The wear resistant coatings of Ni₃Al alloy and Ni₃Al/Cr₃C₂ composites were prepared on 304 stainless steel substrate by laser cladding technique. The microstructure, hardness and wear resistance of Ni₃Al alloy and Ni₃Al/Cr₃C₂ composites were investigated. The results show that the microstructure of the cladding layer of Ni₃Al/Cr₃C₂ consists of matrix γ"-Ni₃Al phase and in-situ self-generated M₇C₃ (M=Cr,Fe) type carbides, and the fine near-circular M₇C₃ is dispersed in γ"- Ni₃Al matrix. Compared with the Ni₃Al alloy cladding layer, the micro-hardness of the Ni₃Al/Cr₃C₂ composites cladding layer is increased by 2.5 times, and the weight loss is only 28% of the vermicular graphite cast iron. Therefore, the laser cladding Ni₃Al/Cr₃C₂ composite cladding layer has good wear resistance.
