摘要

cBN particles reinforced Ti-based composite coatings were prepared by high-speed laser cladding technology in this paper. The thermal decomposition and the evolution behavior of cBN particles during the cladding process were investigated, with the generation of reinforced phases clarified. The solidification structure of the coating and its relationship with hardness, tribological property were also analyzed. The results showed that reinforced phases TiN and TiB could be in- suit synthesized due to the decomposition of cBN. And the content of the residual cBN and the newly formed TiN and TiB could be optimized through the process parameters. The microhardness of the coating can be increased from 610 ± 40HV0.3 to 1217 ± 1HV0.3, with the wear loss reduced by 56%.
