Abstract

The feasibility of in-situ synthesized TiC dispersedly reinforced nickel-based alloy composite layer on AISi1045 steel by powder feeding laser cladding was investigated. It was found that there exists an excellent metallurgical bond between the coating and the substrate, and no cracks. Results revealed that the cladding coating was mainly composed of γ-Ni, TiC, CrB, M23C6, and TiB2, which means that the TiC particles can be formed in-situ. The microhardness of the coating showed variation in gradient; the maximum value was HV0.21100.
