主　　题：PVD coating Mg alloy Taguchi grey approach 

摘      要：This study was an attempt made to explore the possibility of increasing the surface properties of the AZ91D magnesium alloy by applying ZrO_(2)coating using Physical Vapour Deposition(PVD-RF)sputtering *** order to improve the quality of the coating,the PVD process parameter with multiple performance characteristics was optimized by using the Taguchi grey approach.L 18 orthogonal array was selected for conducting the *** proposed Taguchi grey method was find out the optimal process parameter for multiple performance *** optimal combination was attained at chamber pressure of 0.003 bar,argon gas in millibar and power input of 200 *** validation experiment result shows an improvement in the micro hardness and surface ***,the performance characterizations such as SEM,EDX,XRD,coating thickness,surface roughness and micro hardness were measured at optimal process parameter.
