Published: August 2024

Abstract
Erosion-corrosion is a severe problem observed in the coal fired thermal power plant boilers which lead to premature failure of boiler tubes. Thermal spray coatings have been applied successfully to check the erosion-corrosion of boiler tubes. In the present research work NiCrTiCRe coating powders were successfully deposited on T22 boiler steel by two different coating processes i.e. high velocity oxy-fuel (HVOF) and cold spray process. The performance of the coatings in actual power plant boiler were investigated and compared. The uncoated and coated T22 boiler steels were subjected the superheater zone of the coal fired boiler for a total of 15 consequent cycles. The thickness loss data and weight change analysis were used to establish kinetics of the erosion-corrosion. X-ray diffraction, surface field emission scanning electron microscope/energy dispersive spectroscopy (FE-SEM/EDS) techniques were used in the present work for the analysis. The results of thickness loss data indicated that the cold sprayed coating performed better in thermal power plant boiler environment.

Published: August 2024

Abstract
The H-class turbine, introduced nearly a decade ago, has reached a significant milestone with its 100th global sale. With 108 units sold and 91 in operation across four continents, accumulating over 3.2 million fired hours, the SGT5-8000H has established itself as a market leader, setting industry benchmarks for performance. Since its launch, the SGT5-8000H's output has increased from 375 MW to 450 MW, and combined cycle efficiency has surpassed 62%. To maintain optimal performance, the platform combustion system (PCS) of the SGT5-8000H has undergone refurbishment in Berlin since 2017. Beginning with a PCS from Samsun, Turkey, the process involves a detailed inspection, repair, recoating, and final assembly. Advanced technologies, such as blue light scanning, enhance efficiency and enable lifecycle assessments. Innovative repair methods, including 3D printed patch repairs using laser powder bed fusion (LPBF), reduce costs. Laser-based cutting and welding automation further minimizes heat input and distortion, ensuring the PCS's reliability and longevity. These technological advancements contribute to the SGT5-8000H's stable and dependable operation.
Air Plasma-Sprayed MCrAlY Coatings with Low Oxide Content Enabled by Adding a Deoxidizer

Published: August 2024

Abstract
MCrAlY coatings prepared by plasma spraying have been commonly utilized as a thermal protective coating for crucial heated end components due to their high mechanical properties and excellent high-temperature oxidation resistance in aggressive environments. However, the oxides introduced during the preparation process have an adverse impact on the properties of the MCrAlY coatings. In the present work, an attempt was made to deposit NiCrAlY coatings by air plasma spraying (APS) with a low oxide content achieved by introducing carbon as a deoxidizing element. During spraying, the carbon is preferentially oxidized and the formed gaseous CO is completely removed rapidly. Thus, the in-flight oxidation of metal elements can be suppressed to achieve oxide-free particles. Individual in-flight droplets were collected with liquid N2 to clarify the deoxidation effect. Results demonstrate that the oxygen-free NiCrAlYC droplets can be achieved by adding deoxidizing element carbon. The oxide content of NiCrAlYC particles is 0.43 wt.%, being much lower than the 2.87 wt.% of conventional NiCrAlY particles. The adhesive strength test yielded an adhesive strength higher than 71 MPa for NiCrAlY coatings APS-prayed by the oxide-free NiCrAlYC molten droplets, which is much higher than 53 MPa for the conventional NiCrAlY coatings.

Abstract
The US Navy has adopted High-Pressure Cold Spray (HPCS) as a repair technique for corroded and worn components in their fleet of aircrafts, ships, and submarines. HPCS repairs are not only used for depositing corrosion and wear resistant coatings but is being successfully used for dimensional restoration in metal parts and components. By utilizing HPCS, the Navy ensures the longevity and reliability of critical components, even in harsh environments. Whether safeguarding against corrosion or restoring worn parts, HPCS is playing an increasingly critical role in maintaining operational readiness for the US Navy and other DOD agencies, as well as the commercial industry.
Cavitation Erosion in HVOF Thermally Sprayed WC-NiCrBSi Coatings
Authors: Algoburi Ahmed , Ahmed Rehan , Kumar Vishakh 
Published: August 2024

Abstract
Cavitation is a wear process in engineering systems caused by the energy release of collapsing bubbles leading to the failure of critical components such as valves, pumps, and propellers. Thermally sprayed coatings can be applied to improve the wear resistance of these components. This investigation considers a WC-NiCrBSi coating composition under cavitation wear, where the WC phase provides the strength and the NiCrBSi matrix offers corrosion resistance in seawater. Coatings were deposited on AISI 440C stainless steel discs of 32mm diameter and 8mm thickness using industrially optimized parameters for the HVOF JP5000 system. Indirect cavitation tests were conducted using a modified ASTM G32 testing procedure on coated test coupons in as-sprayed and Hot Isostatic Pressed (HIPed) conditions. Two tests were performed for each coating using natural seawater of pH 8.19 at room temperature, and averaged wear values are reported to compare the cavitation rate and cumulative mass loss of the coatings. Coating microstructural phases in the as-sprayed and HIPed conditions were identified using X-ray diffraction. The microstructure of the coating substrate system and post-cavitation test wear scars were investigated using Scanning Electron Microscopy (SEM) equipped with energy dispersive spectroscopy (EDS). This investigation provides an understanding of the corrosive-cavitation wear behavior and failure modes of coatings. The cavitation erosion rate and cumulative mass loss results showed that the as-sprayed WC-NiCrBSi coatings improve the cavitation wear resistance of the substrate.
Influence of Substrate Patterns on the Coating Microstructure in Aerosol-Deposited Alumina Coatings
Authors: Yang Zhenying , Dolatabadi Ali , Coyle Thomas W. 
Published: August 2024

Abstract
Aerosol deposition (AD) is a novel method for producing dense nanocrystalline ceramic films at room temperature. Previous studies primarily used flat substrates with varying hardness and roughness. However, the development of micro-device applications is increasing the demand for deposition on structured/patterned surfaces. To investigate the impact of substrate patterns on coating microstructure and growth mechanisms in AD, alumina coatings were deposited on patterned Si substrates. Si wafers with patterns of micropillars were employed. The coatings were characterized using laser scanning microscopy, scanning electron microscopy, and x-ray diffraction. The microstructure and density of coatings in the valleys were influenced by the size of and the spacing between the patterns. The results revealed that coatings initially formed in the valleys before covering the entire pattern. Fragments of the initial powder particles became trapped between the patterns, adhering to the groove bottoms and pillar sides. Subsequent particle impacts and densification processes transformed these fragments, ultimately filling the gaps between the walls. With further deposition, a uniform coating surface was achieved.
Effect of Surface Preparation by Laser Texturing in Thermal Spraying on the Fatigue Life of the Ti-6Al-4V Alloy

Published: August 2024

Abstract
The Ti-6Al-4V alloy is widely used in aerospace applications for its excellent mechanical properties, however, it presents low wear resistance. It is often coated with a cermet using high-velocity oxy-fuel (HVOF) spraying to improve its wear performance. The Cr3C2-NiCr cermet becomes particularly interesting since it is non-carcinogenic, compared to traditional cermet coatings containing tungsten-cobalt compounds. While the improvement in wear resistance of Ti-6Al-4V with this coating has been demonstrated, its impact on the fatigue performance of the alloy remains to be studied. This is precisely the aim of this study, which focuses on the fatigue life of a Cr3C2-25NiCr-coated Ti-6Al-4V alloy. Among the various influencing factors, surface preparation represents a significant source of crack initiation, particularly in the case of sandblasted surfaces. Indeed, the inclusion of fragmented alumina particles can produce stress concentration zones. Thus, laser texturing, which is a method involving the creation of anchoring points through controlled ablation, can be considered today as a less harmful surface preparation technique. The results obtained from cyclic tensile fatigue tests with a stress ratio of 0.1 for these two surface preparation methods are presented in this paper.

Published: August 2024

Abstract
Cold spray metallization of carbon fiber-reinforced polymers (CFRP) has attracted increasing interest for potential applications in providing lightning strike protection (LSP) to aircraft. This study aims to assess the LSP performance of cold-sprayed copper and aluminum coatings on a Polyaryletherketone (PAEK)-based carbon fiber-reinforced thermoplastic polymer (CFRTP). Lightning strike tests with a peak current of 70 kA were performed on full-surface copper and aluminum coatings, and grid-patterned aluminum coatings. The lightning strike process was captured by a high-speed camera to investigate the fracture behavior of the cold-sprayed CFRTP specimens. Results revealed that the full-surface copper coating, which had higher electrical resistivity and was thinner than the aluminum coating, experienced explosive coating fractures. Conversely, the aluminum coating incurred less damage, effectively protecting the underlying CFRTP from lightning current without visible ply lift or carbon fiber fracture. Furthermore, grid-patterned aluminum coatings also exhibited LSP capabilities, with their denser mesh reducing both the area of coating fractures and the thermal damage to the CFRTP surface.
Offline Robot Programming for Generating Coating Paths Quickly and Accurately
Authors: Schneebeli Stephan , Karandikar D.A. 
Published: August 2024

Abstract
To achieve the optimum quality of thermal spray coating, the material must be applied by controlled, smooth and steady movement. This is best executed by robots. Complex geometries such as hydro turbine parts, hot gas casings or gas turbine blades are difficult to coat with common methods of robot programming such as teach-in. These methods take longer time and tedious calculations to generate robot coating paths. SoftART - a Switzerland based company - has developed a software-based offline programming process to produce robot paths quickly and accurate for an optimized coating result. Based on the 3D-model of the workpiece, the target points of the robot are calculated in a line pattern. Then, the spray direction for each point gets determined with optimized spray angle, considered collision avoidance and robot reachability. Based on this raw data, the line movement will be smoothed to avoid uneven accelerations of the robot axis to produce a uniform coating result. Finally, the data gets postprocessed and a robot specific, ready to run movement program will be generated. This offline programming process is well tested on many different parts and industries and fits best when you have either a complex geometry or many similar parts, which must be coated individually.

Published: August 2024

Abstract
This paper presents an RGB-D visual odometry (VO) approach, designed to enable precise state estimation for a camera-equipped unmanned ground vehicle operating within indoor environments, with a specific focus on its applicability in mobile manufacturing systems including thermal spray. The proposed method utilizes both color images and depth information (through RGB-D camera data) followed by feature detection, frame-to-frame feature matching, and subsequent robot state estimation. To enhance the accuracy of the estimation, an optimization method known as local bundle adjustment, is also integrated into the developed visual odometry framework. For evaluation purposes, we established a ground truth by leveraging an onboard LiDAR sensor to capture the camera path. This ground truth trajectory is then compared with the estimated camera trajectory, incorporating the 3D model of the environment through the utilization of keypoints matched along the path.

Published: August 2024

Abstract
The properties of the coating depend, among other things, on the preparation of the substrate surface and the spray parameters. One of the key properties of the coating is its adhesion to the substrate. Suitable preparation of the substrate surface has a great influence on the adhesion of the thermal spray coating. This work aims to study the influence of surface preparation on roughness of substrate and the resulting surface adhesion of coating. Another aim was to compare the effect of the chosen adhesion measurement method. A series of measurements of the roughness of the samples after grit blasting was performed. The effect of using new and used corundum was also taken into account. The selected coating for testing was TWAS (twin Wire Arc Spray) sprayed Zn15Al. The substrate material was low carbon steel 1.0570. The following adhesion measurement methods were chosen for the experiment - adhesion tensile test according to ASTM C633 - 79 standard, method using a special sample holder based on the ASTM C633 - 79 standard. In addition, a series of measurements were performed using Elcometer 510 Model T.

Published: August 2024

Abstract
Revealed as a process for surface functionalization and repair, cold spray is currently used as a reliable additive manufacturing process thanks to its ability to fabricate dense solid-state deposits with high deposition efficiency. However, cold-sprayed deposits generally present limited mechanical and structural properties due to manufacturing defects such as microporosities and weak interfacial particle bonding. As solutions, post-processing methods such as heat treatment or hot isostatic pressing are proposed to reduce manufacturing defects and optimize final deposit properties. This paper investigates the heat treatment effect on structural and mechanical features of cold sprayed 3D Aluminium part by comparing deposits properties evolution with the additive growth in the as sprayed and heat-treated states. Thus, a study is carried out to identify the right heat treatment conditions for optimizing deposits properties.

Published: August 2024

Abstract
The multi-layered thermal barrier coatings (TBC) are commonly used in the systems exposed to extensive heat, such as jet engines or gas turbines. The testing of coatings' performance is usually carried out using electric or gas furnace. Concentrated solar power (CSP) could provide cost-effective and environmentally friendly alternative using natural energy source. Moreover, it can also simulate materials exposure in real applications, e.g., in solar power-plants. In this study, possibility of using concentrated solar power to test the performance of hybrid YSZ-based TBCs prepared by hybrid water/argon-stabilized plasma (WSP-H) technology was studied for the first time. In service, TBC top-coat layer may be exposed also to so-called CMAS air-borne particles occurring in the atmosphere which may melt at elevated temperatures and penetrate the coating microstructure, inducing crystallographic and volumetric changes therein. Therefore, testing with the presence of CMAS particles was also included in this study to observe its influence on the coating microstructure under solar irradiation. Changes of the coating microstructures were studied using SEM analysis and X-ray diffraction.
