Tribological and mechanical properties of plasssma sprayed 316L and 420 stainless steel layers on the AZ91D commercial magesium alloy

AZ91D 상용 마그네슘합금위에 316L과 420의 스테인레스 스틸의 플라즈마 코팅층의 마모와 기계적 특성

316L and 420 Stainless steels were deposited onto AZ9ID commercial magnesium alloy by plasma spray process with various gas flow rate of, TEX>$H_2$ secondary gas. And hardness as well as were track volume, coefficient of friction also had been measured. wear and hardness were measured by using reciprocal configuration tribometer and microghardness tester, respectively. Also, the microstructure of the coatings surface the cross sectional area of coating surface and cross sectional area of coaing/Substrate interface had been analyzed with Scanning Electron Microscope(SEM) and Optical microscope(OM). Finally, optimal process parameters for the improvement of coating efficiency such as mechanical property and wear behavior were examined.
