Published: January 2023

This paper aims to present a group of compounds Dy2M2O7 (with M = Hf, Ce and Zr) which could be an alternative having the same function as TiO2. Based on our studies and those reported in the literature, we will discuss in detail the roles and the functional mechanism of the catalysts. The results show that Zr2Dy2O7 is the best candidate to be a photo-catalyst: it has a band gap close to 2.2 eV, and a good absorption in visible range compared to the other compound having absorption in UV. The quantum efficiency of Zr2Dy2O7 reaches up to 3%, and the limit of conduction band and valence band are localized in potential redox zone. Doping with Cerium gives another energy level, which allows having other optical transitions and improving the absorption and reaching the quantum efficiency to 4% in a visible range.
Residual Stress Measurement of Cold Sprayed Metallic and Ceramic Coating During Spraying
Authors: Watanabe Yuta , Yamada Motohiro , Fukumoto Masahiro 
Published: January 2023

Abstract
Cold spraying is a promising process for fabricating functional coatings. Because of the solid-state particle deposition, the electrical and chemical properties of the coatings are similar to those of the bulk materials. Mechanical properties, on the other hand, differ from those of bulk materials due to severe plastic deformation of the particles. Residual stress may thus be an important variable to track during cold spraying although the formation mechanism is not entirely clear. In this study, the residual stress of metallic (copper) and ceramic (titania) coatings is measured during the cold spray process. The results are presented and discussed.
Control of Arc Motion in a dc Plasma Spray Torch with a Cascaded Anode
Authors: Zhukovskii Rodion , Chazelas Christophe , Vardelle Armelle , Rat Vincent 
Published: January 2023

Abstract
Two common concerns in dc plasma torches are stability of plasma jet and anode erosion. The challenge is how to get a stable plasma jet with minimal anode erosion. This study tackles this question by using an external axial magnetic field applied to a cascaded plasma torch. A 3D, time-dependent model of the torch is used to predict the value of the magnetic field and its effect on heat flux to the anode as well as plasma jet stability. The model couples the gas phase and electrodes, making it possible to follow anode temperature evolution. For specific operating conditions, the model predicts an azimuthal self-magnetic field induced by electric arcing and the subsequent effect of an external field on arc attachment and anode wall temperature. This approach is expected to provide a better understanding of arc behavior in dc plasma torches and facilitate the control of anode erosion.

Authors: Lima Rogerio S. , Guerreiro Bruno M.H. , Curry Nicholas , Leitner Matthias , Körner Kari 
Published: January 2023

Abstract
In this study, different sets of plasma-sprayed YSZ thermal barrier coatings were deposited via Ar/H2 and N2/H2 plasmas and compared based on deposition efficiency (DE), thermal conductivity (TC), and furnace cycle testing (FCT). The top-performing coatings exhibited equivalent FCT lifetimes with TC values in the range of 1.15-1.25 W/mK at 1200 °C, but the deposition efficiency of those produced with N2/H2 plasma was twice as high, resulting in a 55% reduction in production costs.
Dilatometric Study of High Temperature Exposure Effects in Multiphase Fe-Al Intermetallic/Oxide Ceramic Coating Deposited by Gas Detonation Spraying
Authors: Panas Andrzej J. , Senderowski Cezary , Fikus Bartosz 
Published: January 2023

Abstract
A wide range of properties can be achieved in intermetallic coatings applied by gas detonation spraying (GDS). The properties of Fe-40at%Al GDS layers, however, may change when exposed to temperatures exceeding a threshold level. To characterize such changes, Fe-40at%Al GDS coatings were subjected to systematic dilatometric studies in which temperatures were cycled from room temperature to 1180 °C. The investigation revealed both irreversible and reversible phase transitions as described in the paper. Dilatometry measurements obtained from sintered samples made from the same powder are presented for comparison.

Authors: Lapushkina Elizaveta , Ying Sheng , Mary Nicolas , Ogawa Kazuhior , Normand Bernard 
Published: January 2023

Abstract
Cold spraying is a semi-empirical method in that spray parameters must be optimized experimentally in regard to coating quality and deposition efficiency. In this work, porosity and deposition efficiency are the key parameters in the optimization of corrosion-resistant zinc coatings produced by high-pressure cold spraying. The deposition process is described along with the tests used to assess the morphology, adhesion, and anticorrosion properties of the coatings obtained.

Published: January 2023

Abstract
The objective of this study is to assess the wear resistance, hardness, and porosity of HVOF-sprayed Cr3C2-25NiCr coatings applied using different oxygen and C3H8 flow rates. In the experiments, six coating samples were prepared and subjected to various tests. The sample deposited with the highest oxygen flow rate and lowest fuel-oxygen ratio exhibited the lowest porosity and highest microhardness. In general, the higher the surface hardness, the better the erosion and cavitation wear resistance. The most intense wear occurred during the erosion test conducted with an impingement angle of 60°.
Erosive Wear Testing of Laser Clad and HVOF Coatings for Drilling in Mining
Authors: Schulz C. , Charrault E. , Hall C.J. , Shläfer T. 
Published: January 2023

Abstract
This study assesses the erosive wear performance of hard-phase-reinforced coatings developed for use on hammer drills employed in mining operations. Several laser-clad coatings consisting of a nickel matrix with various tungsten carbides were evaluated along with two Fe-based alloys, FeCrBSi and FeCrNiBSi, and a WC-CoCr reference layer deposited by HVOF spraying. Erosion tests were conducted in 15° steps up to an angle of 90° and coating performance was determined based on volume loss obtained by 3D profilometry. At low angles, the more brittle materials lost significantly less volume, but at 90°, wear-resistant steel performs almost as well as a hard-phase loaded coating. Laser-clad layers with spherical fused tungsten carbides (FTC) performed better overall than coatings with regular (angular) FTC.
Microstructural and Performance Analyses of Thermally Sprayed Electric Resistance Heating Systems as De-Icing Elements
Authors: Rad Milad Rezvani , McDonald André , Bajgiran Morvarid Mohammadian , Moreau Christian 
Published: January 2023

Abstract
This study investigates the microstructure and efficiency of coating-based heating elements produced by deposition of various powders, including aluminum oxide (Al2O3), alumina-titania (Al2O3-TiO2), nickel-chromium (NiCr), and copper, using flame spraying, suspension plasma spraying, high-velocity oxyfuel (HVOF) spraying, and cold spraying techniques. The main goals are to assess the dielectric strength of flame and plasma sprayed alumina, compare the electrical resistivity of HVOF and flame sprayed NiCr, and obtain coating cross-sectional images to shed light on the challenges and potential of different heating element designs. The Al2O3 layer produced by suspension plasma spraying appeared to be more reliable due to its cauliflower-like structure, corundum content, and hygroscopic properties. Resistivity was found to be higher in the flame sprayed NiCr than in the HVOF deposit mainly due to discontinuities and imperfections such as cracks, pores, and oxygen content. The micrographs taken from sample cross-sections show penetration of flame-sprayed NiCr into the flame-sprayed Al2O3 and Al2O3-TiO2 layers, which decreases the effective thickness of the dielectric. However, interlocking between NiCr and Al2O3-TiO2 coatings can be beneficial when cohesion is a concern.
