Initial powder feedstock was composed of an orthorhombic α-MoO3 phase, and the average powder particle size was 6.7 μm. As a result of the APS coating process, a MoO3 coating layer with a thickness of about 90 μm was obtained. Phase transformation occurred during the process, and the coating layer consisted of not only α-MoO3 but also β-MoO3, MoO2. Phase transformation could be due to the rapid cooling that occurred during the process. The properties of the coating layer were evaluated using a nano indentation test. Hardness and reduced modulus were obtained as 0.47 GPa and 1.4 GPa, respectively. Based on the above results, the possibility of manufacturing a MoO3 thick coating layer using thermal spray is presented.}, type={Article}, title={Manufacture of MoO3 Coating Layer Using Thermal Spray Process and Analysis of Microstructure and Properties}, URL={http://www.journals.pan.pl/Content/125129/PDF/AMM-2022-4-47-Kee-Ahn%20Lee.pdf}, doi={10.24425/amm.2022.141089}, keywords={MoO3, Thermal spray, Atmospheric plasma spray, Microstructure, properties}, }
