Abstract

With 2 kW continuous wave Nd-YAG laser, SiC ceramic powder was laser-cladded on the AA6061 aluminium alloy surface. Within the range of process parameters investigated, the parameters were optimized to produce the SiCpreinforced metal matrix composites (MMC) modified layer on AA6061 alloy surface. After being treated, the modified layer is crack-free, porosity-free, and has good metallurgical bond with the substrate. The micro-structure and chemical composition of the modified layer were analyzed by such detection devices as scanning electronic microscope (SEM-EDX) and X-ray diffractometer (XRD). The performance of electrochemical corrosion and cavitation erosion and their mechanism were estimated by the microhardness tester, potentiostat and ultrasonic-induced cavitation device.
