The synthesis of TiC-TiB2-Ni composite coating on steel substrate using electro-thermal explosion ultra-high speed spraying (EEUSS) method has been investigated. The coating exhibits a compact microstructure and good interface bonding. TiC-TiB2-Ni coating consists of TiC, TiB2, Ni, as well as the residual C Microstructure characterization reveals micro-sized clubbed TiB2 particles with the length of 5-10 mu m and submicron-sized spherical TiC particles with the average diameter of 1 mu m and these different morphologies are due to their respective crystal structure. The average hardness Value for TiC-10TiB(2)-Ni and TiC-20TiB(2)-Ni are HV0.3 1800 and HV0.3 2000.
