主 题:AZ91 magnesium alloy Al-TiC coating TIG alloying micro-hardness dry sliding wear
摘 要:An attempt was made to improve the surface properties of the AZ91 Mg alloy through surface alloying of a mixture of Al and TiC with the help of TIG arc as heat *** microstructural evolution of the alloyed layer on the AZ91 alloy was analysed through SEM and XRD *** micro-hardness and the dry sliding wear behaviour were assessed by Vickers micro-hardness tester and pin-on-disc wear test setup,*** is revealed that almost uniform alloyed layer forms on the AZ91 alloy substrate for a specific current and scan speed employed in the present *** alloyed layer exhibits hardness value up to 305 HV0.25,and almost negligible wear as compared to the as-received AZ91 alloy substrate.
