A comparative study of MoSi2 coatings manufactured by atmospheric and vacuum plasma spray processes
Source abstract
Abstract
Abstract In this work, MoSi 2 coatings were manufactured by atmospheric plasma spraying (APS) and vacuum plasma spraying (VPS) technologies, respectively. Phase composition and microstructure of the coatings were characterized by X-ray diffraction and scanning electron microscopy. Microhardness, void and oxygen content of the coatings were also determined. Oxidation behavior of the coatings at high temperature was examined. The results showed that the surface of VPS-MoSi 2 coating was dense and homogeneous. However, there were many microcracks formed on the surface of APS-MoSi 2 coating. The VPS-MoSi 2 coating also had lower void and oxygen contents, higher Vickers hardness compared with those of APS-MoSi 2 coating. Besides, oxidation resistance of the VPS-MoSi 2 coating was better than that of APS-MoSi 2 at 1500 °C.
