摘要	Ni+WC composite cladding was prepared on the surface of 45 # steel by vacuum cladding technology. The formation mechanism of nickel-based composite coating was investigated by intermittently sampling. The results show that a Ni-based composite cladding with metallurgical fusion to the matrix and uniform distribution of WC hard particles is obtained on the surface of 45 steel. The entire cladding consists of a 4 mm thick composite layer, a 1 mm thick transition layer, a 20 μm thick diffusion fused zone, and a 250 μm thick diffusion affected zone. The composite layer composes of WC and W-rich multiphase carbide formed after decomposition, surrounded by Ni particles; The main phase constituents of the composite cladding layer include γ- Ni solid solution, Cr7C3, Ni2.9Cr0.7Fe0.36, Cr23C6, Ni3Fe, Ni3Si, Ni3B, W2C and C. The vacuum cladding process mainly includes the formation of a micro-sintered neck between the particles in the heating stage before the Ni-based alloy particles reach its melting point, and the melting of the Ni-based alloy particles at the beginning stage of its melting point and the third stages of fusion diffusion in the heat preservation stage and position adjustment of the WC particle within micro-area. © All right reserved.
