Abstract

Metal matrix composite (MMC) claddings can be effectively used in severe wear working conditions. The present work successfully develops the MMC clad of Ni + 10% WC8Co + Cr3C2 based material on SS-316L substrate using cost-effective microwave hybrid heating technique. The developed composite clads showed the refined microstructure with the existence of randomly dispersed reinforcement particles inside the Ni based matrix. The phase analysis study results of the clad region revealed the formation of various hard phases of Co3W3C4, Cr7¬¬Ni3, NiC, NiW, W2C, Fe6W6C, Fe7C3, FeNi3 during microwave heating The hard phases present in the clad region contributed to the enhancement in the microhardness. The mean micro-hardness of the clad region was observed as 550 ± 40 HV. Further, composite clad exhibited excellent wear resistance than SS-316L substrate under different tribological conditions.
