TiC/Ni cermet cladding layer on the surface of 16Mn steel was fabricated with plasma cladding process. Different additions of Mo were 0%, 5%, 10% and 15% in mass percent. The cladding layer was composed of ceramic particles and Ni alloy binder. And the gradient distribution of ceramic particles was observed. And Mo was found in TiC ceramic particles in solid solution. The mechanical properties of the cladding layers with different Mo additions were all better than the cladding layer without Mo. However, the cladding layer with 10% Mo had more defective microstructure and worse mechanical properties.
