PSI: New Diagnostics for the Determination of Particle Size and Shape in Thermal Spray Processes
Authors: Streibl T. , Landes K.D. , Forster G. 
Published: July 2021

Abstract
In the thermal spraying process the quality of the produced coating is determined by the state of the particles before they impact on the substrate[l]. For the spray particle diagnostics a new method is offered by the development of the Particle-Shape-Imaging (PSI) technique. This method is intended for the analysis of size and shape of individual particles within the plasma jet. The method is based on telemicroscopic imaging of the particle shades. Similar to the Laser-Doppler-Anemometry a cw laser beam is split into two beams of equal intensity, which are superimposed in the focal plane of a Long-Distance-Microscope. The detection system consists of a CCD camera with a Micro-Channel-Plate intensifier allowing exposure times of few nanoseconds. When a particle passes the measuring volume exactly in the focal plane, the two laser beams generate individual shades, which congruently superimpose on the CCD Chip in the image plane of the telemicroscope. If a particle passes the measuring volume not exactly in the focal plane, the two generated shades are separated in the image plane. By this effect the position of the particle relatively to the focal plane can be measured. From the area and the contours of the shades, particles can be classified regarding size and form. Corresponding distributions of the particles within the plasma jet as well as changes of the particle form in the melting process can be determined.
Theory of Particle Composition Analysis During Thermal Spraying
Authors: Wilden J. , Frank H. 
Published: July 2021

Abstract
The properties of thermally sprayed coatings significantly depend on the alloy composition and the adjusted process parameters. In addition to the powder certificate it may be useful to analyse the chemical composition of the sprayed powder during the spraying process itself. The principle of composition analysis is similar to the chemical analysis in an ICP plasma but the boundary conditions are more complex because the sprayed powder should not be completely evaporated in a thermal spray process. Nevertheless all thermal spraying processes lead to a certain evaporation of the species and to excitation of atomic states. The transition into the ground state occurs under emission of characteristic lines. The intensity of these lines is influenced by the plasma temperature, the particle temperature, the temperature dependent evaporation rate of the alloying elements and the powder feed rate. In consideration of the boundary conditions and the information from a detailed analysis of the emitted spectra the lines can be used to quantify the chemical composition of the sprayed alloys online. The theory of the principle for on-line analysing the chemical composition will be deduced and the first experimental validation will be presented.
An Attempt to Improve the Deposition Efficiency of AI2O3 Coating by HVOF Spraying
Authors: Shimizu Y. , Sugiura K. , Sakaki K. , Devasanapathi A. 
Published: July 2021

Abstract
High Velocity Oxy-Fuel (HVOF) method using propylene as a fuel gas was employed to spray alumina particles. In order to improve the coating characteristics such as the deposition efficiency and the hardness, three HVOF gun nozzles of varying geometry were designed and tested experimentally. The spraying process was also simulated numerically for each of the nozzle geometries to understand their effectiveness in influencing the velocity and temperature of the sprayed particles. The coating was characterized using optical and scanning electron microscopy (SEM), micro-vickers hardness test and X-ray diffractometry (XRD). Results showed that with the use of a convergent and divergent type gun nozzle, similar to that of a Laval nozzle, the extent of melting of the alumina particles could be increased. This was exhibited by an increase in the deposition efficiency to the extent of 45%. However, the sharp changes in the convergent and divergent nozzle geometry, resulted in fusion and agglomeration of alumina particles leading to spitting during the spraying process. The results clearly showed that alumina coatings of excellent hardness in the range of 920-1290 HV, with a relatively dense microstructure could be obtained in HVOF method irrespective of the gun nozzle geometry, provided the spraying parameters are properly controlled.
Modeling of Spray Deposition and Robot Motion Optimization for a Gas Turbine Application

Published: July 2021

Abstract
The complexity of many components being coated in the aircraft industry today makes the traditional trial and error approach to obtain uniform coatings inadequate. To reduce programming time and further increase process accuracy a more systematic approach to develop robot trajectories is needed. In earlier work, a mathematical model was developed to predict coating thickness for thermal spray deposition on rotating objects with rotationally invariant surfaces. The model allows for varying spray distance and spray direction but is simple enough to give very short simulation times. An iterative method for robot feed optimization to obtain uniform coatings was also proposed. Currently, the use of the model in engineering practice is being evaluated. A MATLAB implementation of the model has been integrated with a commercial off-line programming system, giving a powerful and efficient tool to predict and optimize coating thickness. Simulations and experimental verifications are presented for two zirconia plasma sprayed parts.

Published: July 2021

Abstract
As applications of thermal spray processes are expanding, the importance of computer-aided design systems and computer-aided engineering systems for these processes has been growing. The principal objective of this study is to propose a new analytic method for the prediction of coating thickness and deposition efficiency. This method is called the particle tracing method and is based on the Monte Carlo simulation method. In order to evaluate the validity of this model, several tests were carried out. The same stainless steel 316L layers coated by the HP/HVOF process (TAFA JP-5000) were used throughout each test. First, spray patterns were observed which had formed on flat-plate specimens from various spray gun angles. Coating thickness distributions on several curved planes were consequently investigated. Finally, the coating process for a blade of a compressor in a gas turbine was simulated. In the right of the results of these experiments, it is summarized that the calculated values of the coating thickness obtained by our method are in good agreement with experimental values. The accuracy is within 10% of the maximum thickness value in each specimen, except for at the edge of the work-piece. In conclusion, the particle-tracing method can be applied to the fundamental analytic model in the CAD or CAE system for thermal spray processes.
Characterization of Al2O3 and SiC Particles, Reinforced Al Powders, and Plasma Sprayed Wear Resistance Coatings
Authors: Bach Fr.-W. , Duda T. , Babiak Z. , Bohling P. , Formanek B. 
Published: July 2021

Abstract
Aluminum coatings reinforced with either Al2O3 or SiC particles were deposited onto aluminum substrates and subjected to various tests. The coatings were made with mechanically alloyed powders via atmospheric plasma spraying (APS). Both types of coatings had uniformly distributed hard particles, porosities in the range of 4 to 5%, and bond strengths of around 20 MPa. The wear resistance of the SiC-reinforced coatings, however, was almost 35% higher than the coatings containing Al2O3. X-ray examination (XRD) showed that the Al2O3 particles undergo partial phase transformation during spraying, making them more prone to wear.
Microstructure and Property Control of CoNiCrAlY Based Abradable Coatings for Optimal Performance
Authors: Wei X. , Mallon J.R. , Correa L.F. , Dorfman M.R. , Ghasripoor F. 
Published: July 2021

Abstract
A CoNiCrAlY-hBN/Polyester material has recently been developed for clearance control applications in gas turbine compressors that use titanium alloy blades. While engine tests serve as the final evaluation of the coating performance, quality assurance laboratories and production shops would rely upon the more readily available coating hardness values to predict performance. This paper will focus on the reproducibility of coating macrohardness with a plasma spray process. It is shown that plasma spray parameters affect the hardness of CoNiCrAlY-hBN/Polyester coatings by changing the level of polyesters retained in the coating and the volume percentage of metallic matrix. The correlation between hardness, retained polyester level and microstructure of these coatings is captured in a coating hardness map from which desired microstructure and polyester entrapment are determined. Based on the understanding of the correlation between coating hardness and microstructural features, the use of additional criteria other than hardness such as retained polyester level and non-metallic portion of the coating is recommended in order to assure the quality of the coating more effectively.
Microstructure and Corrosion Resistance of HVOF Sprayed 316L Stainless Steel and Ni Base Alloy Coatings
Authors: Kuroda S. , Fukushima T. , Kodama T. , Sasaki M. 
Published: July 2021

Abstract
316L stainless steel and Hastelloy C alloy powders were sprayed by an HVOF apparatus onto mild steel substrates. The microstructure, pore size distribution, composition and corrosion resistance of thus obtained coatings were evaluated experimentally. Corrosion resistance in sea-water was examined by monitoring the impedance and corrosion potential of samples immersed in artificial sea-water at 300 K over a period of more than 3 months and also by polarization measurement. It was found that the stainless coatings composed mainly of plastically deformed particles and some splats which were molten at the impact. By increasing the combustion pressure, the porosity as measured by mercury porosimeter could be reduced to below 1%. In comparison, Hastelloy C deposits sprayed under the standard condition were so dense that its porosity could not be measured by the porosimeter. The polarization curve and the results of impedance monitoring both exemplified that the Hastelloy C coatings possess much superior corrosion resistance to the stainless coatings in sea-water, which was attributed to the higher density and better adhesion of the Ni-base alloy coatings.
Influence of Flame Parameters on Stainless Steel Coatings Properties

Published: July 2021

Abstract
Owing to high particle velocity upon impact, and consequently low porosity and high bond strength of so-obtained coatings, HVOF spraying process is widely used to improve components life in service. However, many parameters can affect metallic coatings properties, especially un-melted particles and oxidation level. Flame parameters, such as calorific power, combustion ratio and temperature, are of prime importance. The aim of this work was focused on the influence of these parameters on stainless steel coatings characteristics. For different substrate temperatures, maintained through CO2 cooling nozzles, those parameters varied independently. Flame characteristics were computed using a simple model for propylene as fuel gas. Microstructure investigation as well as oxide content measurements and microhardness were obtained. It appeared that combustion temperature, in the range studied (2600-2750K) was not a critical factor. However, combustion ratio and calorific power greatly influenced coating properties: an increase of oxide content, and consequently a higher microhardness, was observed when combustion ratio decreased as well as when calorific power increased.

Abstract
Shreenath has been engaged in the manufacturing and reclamation of engineering components by using the full range of thermal spraying since 1990. The analytical case studies of some of the tribological solutions provided to the core industries in Central India by HVOF spraying are presented in this paper. The case studies presented in this paper are the reclamation of the Vertical shaft of a bowl mill used for feeding crushed coal to the power plant, the engine spares of the earth moving machinery of the mining industries and the press rolls made up of chilled cast alloy steel, of defence industry. The surface characteristics needed for these applications, along with high hardness, bond strength and thermal conductivity could be achieved by the HVOF spraying using Topgun. In all the cases, the component life has been increased few folds and a direct cost saving of 30-70% was achieved. In addition, such an optimized reclamation reduces the down-time loss and improves the working efficiency.
Processing Quasicrystalline Powders to Produce Variable and Unique Coating Properties
Authors: Hermanek F.J. 
Published: July 2021

Abstract
Quasicrystals are materials whose structure cannot be understood within classic crystallographic methodology. Quasiperiodic structures have a long-range orientation order but lack transitional periodicity. This non-periodic structure gives quasicrystals a unique range of physical properties including: poor thermal conductivity; excellent crystallographic stability up to their melting point; can be thermally sprayed to display either wear resistant or abradable characteristics; possess excellent release properties (low coefficient of friction); and, they are non-work hardenable. This effort describes parametric conditions utilized to deposit coatings of identical parent metal chemistry but with vastly different end properties.
