Authors: Vernando Vernando , Mulyadi Indra Hardian 
Published: May 2021

Overall Equipment Effectiveness (OEE) adalah metode yang digunakan untuk menghitung nilai efektivitas dari sebuah mesin atau peralatan. Jika nilai OEE ≥ 85%, maka mesin dapat dikatakan efektif. Jika nilai OEE < 85%, maka mesin tidak efektif dan akan dilakukan analisis untuk mencari akar permasalahan, di antaranya menggunakan metode Failure Mode and Effect Analysis (FMEA). Penelitian ini bertujuan membuat sistem penghitung nilai efektivitas mesin forming menggunakan metode OEE. Limit switch dan Arduino UNO digunakan untuk mengambil data output dari mesin, seperti jumlah produksi, total durasi kerja mesin, dan total durasi mesin berhenti. Data diolah menggunakan Microsoft Visual Studio (C#) dan disimpan dalam database sehingga dapat ditampilkan dalam bentuk laporan bulanan menggunakan Crystal Report. Pengujian lapangan sistem ini dilaksanakan untuk menghitung OEE pada mesin die form. Berdasarkan hasil dari pengujian tersebut, sistem penghitung ini berfungsi dengan baik dalam menghitung OEE mesin die form tersebut, yang dalam hal ini berada dalam kisaran 59,05% s.d 97,17% (efektivitas di bawah nilai World class standard).

Total pancreatectomy and salvage completion pancreatectomy-early and late outcomes without Islet cell auto-transplantation
Authors: Maharjan Dhiresh Kumar , Thapa Prabin Bikram 
Published: May 2021

Background: Total pancreatectomy was abandoned for decades because of high peri and post-operative morbidity and mortality. However, with better peri-operative outcome and post-operative management of exocrine and endocrine insufficiency, the hesitancy to perform total pancreatectomy has been disappearing.
Objectives: This study aims to study exocrinal and endocrinal effects of total pancreatectomy without Islet cell auto-transplantation and compare quality of life index among total pancreatectomy with Whipple patients.
Methodology: This is a prospectively conducted matched-pairs study. Group A underwent total or completion pancreatectomy after non-salvageable complications of Whipple operation. A matched-pairs analysis of quality of life index of these patients by using SF-36 questionnaire were compared with Group B who underwent Whipple operation during the same period of time, according to age, gender and pre-operative diagnosis.
Results: In four years (from February 2016 to February 2020), 160 patients underwent Whipple operation. The mean age of the patients was 59.9 +/-14.3 years. A total of nine patients underwent total pancreatectomy, among which two had per-operative decision of total pancreatectomy and seven had completion pancreatectomy. Median post-operative hospital stay was 11 days with two mortalities. Median follow-up of 12 months and quality of life index of total pancreatectomy patients were comparable to Whipple patients, although a few single quality of life items were reduced.
Conclusion: Exocrinal pancreatic supplements and long acting insulin have augmented control of diabetes despite of not using Islet cell auto-transplantation. Quality of life index of total pancreatectomy patients were comparable to that of Whipple patients. Hence, this study signifies the importance of completion pancreatectomy following non-salvageable complications after Whipple operation in order to save life.
On the Microstructures of Thermally Sprayed “Peek” Polymer
Authors: Liao H. , Beche E. , Coddet C. , Berger F. 
Published: May 2021

Abstract
Polymer coatings find increasing interest for anticorrosion applications and others. Thanks to its extraordinary properties (high chemical stability, low creep rate and good electrical resistivity at relatively high temperature) PEEK (Polyetheretherketone) polymer is now considered as a challenging matierial. In this work, PEEK polymer powder was thermally sprayed with different processes. Particle impacts were observed and coating was analyzed by infrared spectrometry. The temperature of the substrate was shown to play an important role in the formation of dense and continuous coatings. Thermal degradation during spraying produces new carbonyl species due to chain scissions; but the amount of decomposition could be controlled from the choice of spraying conditions.
Plasma Sprayed Self-Lubricating Cr2O3-CaF2 Coatings: Friction and Wear Properties
Authors: Vos F. , Delaey L. , De Bonte M. , Froyen L. 
Published: May 2021

Abstract
An alternative production route to obtain thermally sprayed self-lubricating ceramic coatings is proposed and microstructural, friction and wear properties of these coatings are discussed. A preliminary powder treatment shows to induce a higher degree of homogeneity compared to conventionally deposited composite coatings, offering some perspectives for a further improvement of the lubricating and wear properties. This approach is illustrated using CaF2 as a solid lubricant dispersed in a Cr2O3 matrix, where the high melting point of the latter (Tm{Cr2O3} = 2460°C) necessitates plasma spraying as deposition technique. The microstructure of the coatings is evaluated by a metallographic study of sections perpendicular and parallel to the substrate surface. Wear and friction behaviour is evaluated using reciprocating wear test Wear tracks are analysed by means of laser profilometry. The results are discussed in relation to test and production parameters. Test temperature as well as solid lubricant concentration predominantly affects the wear and friction properties. Using a surface temperature of 400°C, a friction coefficient of 0.25 and a wear volume of 37 x 103 µm3 after 10,000 cycles are obtained for a coating containing 16 vol.% of CaF2.

Authors: Knuuttila J. , Ahmaniemi S. , Leivo E. , Sorsa P. , Vuoristo P. , Mantyla T. 
Published: May 2021

Abstract
Several recently published studies have shown remarkable improvements in dry abrasion resistance and corrosion resistance of aluminum phosphate sealed oxide coatings when compared to unsealed ones. There are numerous applications in chemical industry where a corrosive environment is accompanied with abrasive or erosive particles. In this study the wet abrasion resistance and slurry erosion resistance of aluminum phosphate-sealed and unsealed oxide coatings were studied and compared to their dry abrasion resistance. In wet abrasion tests kaolin and water mixture was used as the abrasive. In slurry erosion tests several abrasives in water with various pH values was used as the erosive medium. The coatings were characterized for microstructure and their wear mechanisms were analyzed using SEM. The results from wear tests are reported and correlated with coating properties. The influence of coating quality to the relative improvement achieved by sealing is presented and discussed.
Elevated Temperature Erosion Resistance of Several Experimental Amorphous Thermal Spray Coatings
Authors: Wang B. 
Published: May 2021

Abstract
The elevated temperature erosion resistance of experimental amorphous thermal spray coatings was determined in a laboratory elevated temperature erosion tester. Test conditions attempted to simulate the erosion conditions found at the combustor waterwall tubes in fossil fuel fired boilers. Erosion tests were conducted on four experimental amorphous thermal spray coatings, using the bed ash retrieved from an operating coal fired boiler. An experimental arcspray process was used to spray coatings. These results were compared with erosion test results of two common structural materials, two commercially available arc-sprayed coatings, and a proprietary HVOF coating. Test results indicated that the Duocor coating had the highest erosion resistance among the four experimental coatings, it showed equal resistance to the HVOF coating (DS-200). Compared to AISI 1018 steel, both Duocor and DS-200 coatings reduced material wastage by 26-fold. Other test results indicated that the XJ-16, 60T and Armacor M coatings had equal erosion resistance reducing material wastage approximately 7-fold, while Armacor CW reduced by 10-fold. Only slightly better than the unprotected 1018 steel, the X-20 coating performed poorly on erosion tests. The high erosion resistance of Duocor and DS-200 coatings was attributed to their high densities and fine splat structures.
A Study on the Wear Characteristics of Plasma Sprayed NiCrSiB/WC-12Co Mixed Coating
Authors: Ahn H.S. , Lee C.H. 
Published: May 2021

Abstract
Air plasma spray coatings of three different WC-12%Co powders based on the powder manufacturing methods were conducted. S&F (Sintered and Crushed) WC-12%Co and NiCrSiB mixed powder with different ratio were also sprayed. The best wear resistance of S&F WC-12%Co coating was mainly due to its high hardness related with large amount of homogeneously and uniformly distributed retained carbides. The wear resistance of blend coatings increased with increasing WC-12%Co weight percent which was associated with the fact that the wear resistance of all coatings increased with increasing hardness and decreasing friction coefficient. But the exact relation of wear resistance with cohesive bond strength could not be found. The dominant wear mechanisms of WC-12%Co coatings were adhesive wear, tribo-film formation by material transfer, fatigue crack, particle (splat) fracture and delamination (spallation of coating layers). In the case of blend coatings, when the weight percent of WC-12%Co was small plastic deformation and abrasive mark (or scratching) by asperity and/or hard particle were observed. with increased weight percent of WC-12%Co the wear mechanism was closer to that of WC-12%Co coatings where no plastic deformation and abrasive mark was observed.
Effect of Powder Type and Composition on the Erosion and Abrasion of HP/HVOF Deposited WC-Co Coatings
Authors: De Villiers Lovelock H.L. , Van Wyk P. 
Published: May 2021

Abstract
WC-Co and WC-CoCr coatings were deposited with the JP-5000 liquid fuel HP/HVOF system using various thermal spray powder types. The microstructure, microhardness, deposition rate and wear resistance of the coatings were characterized. The results show that these coatings provide significantly more protection from dry three-body abrasion than from dry sand erosion, when compared to mild steel. They also provide more advantage at low angles of erosion than at high angles of erosion. Furthermore, the coating composition was found to have a significant effect on the wear rates, with WC-CoCr providing the best wear resistance even after taking the higher cost of the powder into account. The powder manufacturing route had only a secondary effect on the wear rates, except in the case of fused and crushed powder, which produced an inferior coating.

Authors: Giroud A. , Jouanny C. , Heuze J.L. , Gaillard F. , Guiraldenq P. 
Published: May 2021

Abstract
Different oxides layers have been studied by friction in natural sea water medium under the same conditions (Cr2O3, Al2O3, Al2O3 + Cr2O3). The evolution of different parameters have been analyzed: friction coefficient, electrochemical potential, degradation of the layers in the contact, impedance spectroscopy. The main result observed is concerned by the cracking of the coatings under stresses, in such a way interconnection paths are rapidly present between the substrate and the sea water medium through the layers. The coating impregnation process by epoxy, before the tribocorrosion tests, improve the protection of the substrate against the corrosion.
The Tribology of Amorphous Surfaces Formed by Wear of Thermal Spray Coatings
Authors: Scruggs D.M. 
Published: May 2021

Abstract
This paper describes the wear induced transformation of crystalline metal surfaces into amorphous and/or microcrystalline surfaces that exhibit gross changes in the fundamental properties of friction, wear, hardness and toughness. The coatings are applied using wire and powder feed to TWAS and HVOF equipment. Wear processes investigated include adhesive wear, low stress abrasion, grinding wear and galling. The effects of chemical makeup of the surfaces and the alloy structure are examined using microscopy and x-ray diffraction. The surface & underlying coating characteristics including roughness, microstructure, hardness and friction coefficient are determined. Results show that the surface structure is dependent on the wear vector. The structural transformation is a function of the chemical makeup and intrinsic wear resistance of the crystalline alloy coupled with the energy input of the wear process. High energy wear such as grinding wear can overcome the transformation. The results also suggest that the micro-welding that occurs between asperities in crystalline alloys is replaced by a flow process on the transformed surface. Coating structure, glass transition temperature, crystallization temperature and critical cooling rate of the transformed surface are much more significant than the chemistry of the alloy once the transformation takes place.

Published: May 2021

Abstract
Reducing operating clearance between the HP turbine and shroud is a means often used by engine manufacturers to improve the efficiency of new generation gas turbines. This, in turn, requires the development and use of clearance control coatings to minimize the effects of degradation and wear associated with rubbing. In this study, the authors assess two coating systems: VPS NiCoCrAlYTa coatings for blade tips and plasma-sprayed MCrAlY, a potential abradable coating. In order to understand the wear mechanisms of these systems, block-on-ring and fretting tests were conducted and the relationship between microstructure and wear was examined. The results were then compared to those of rub tests performed with real engine components.

PTA Reclamation of Cast Iron and Aluminum Alloys Substrate with NiCu Film Deposited by Tape Casting
Authors: Leylavergne M. , Grimaud A. , Fauchais P. , Chartier T. , Baumard J.F. 
Published: May 2021

Abstract
Plasma transferred arc (PTA) is now currently used for reclamation of worn materials or to provide wear or corrosion resistant coatings welded to the base material. However, the powder injection in the molten pool created at the coated part surface is a critical parameter. In order to avoid coating reproducibility problems induced by the powder feed rate, the way to coat substrate surface with powder before the PTA treatment has been studied. As the powder cannot simply be deposited onto the substrate because of the plasma flow which would blow it off before melting it, tape casting process was used to obtain an adherent powder layer on the material surface. In this paper, tape casting of NiCu particles is described and the different organic additives used to obtain a homogeneous nickel copper film on cast iron and AG3 aluminum alloys are presented. The first results of the treatment of these films by PTA reclamation are then shown.

Published: May 2021

Abstract
The detonation gun (D-Gun) coating technology which results in coatings with outstanding properties has found extensive applications especially in the aerospace and engineering industry. Though the D-Gun process has been in use for the last 30 years or so, the basic mechanisms which lead to such an outstanding combinations of properties is not yet fully understood. This has been primarily due to the fact that the coating property ultimately depends on the combination of powder particle temperature and velocity at the time of its impact on the substrate to be coated and so far measurement of these parameters has not been possible. As a result, indirect correlations between D-Gun variables like fuel gas to oxygen ratio, powder feed rate, firing frequency and working distance and coating properties have been developed but without the knowledge base of how these D-Gun variables affect the powder particle temperature and velocity. An in-flight particle diagnostic sensing system has been recently installed in our laboratory and this system allows for the simultaneous measurement of particle velocity and temperature. In view of the above, a major programme has been launched to study the effect of particle velocity and temperature on the coating properties (like coating hardness, porosity, bond strength, XRD etc.) for a wide range of coatings. The preliminary results from the above investigation, pertaining to Cr3C2-25NiCr coatings obtained using D-Gun, will be presented and discussed in this paper.
