    Abstract

    Composite coatings including TiC particles are fabricated on the TC21 titanium alloy surface by the laser cladding process. The effects of SiC particle size on the phase compositions, microstructures, hardness, friction and wear properties of the cladding coatings are investigated. The results show that the main phases of the cladding coatings are Ti2Ni, TiNi, Ti5Si3 and TiC and the TiC particles refine the grain size. The addition of micro-SiC particles makes the hardness and the wear resistance of the cladding coating surface increase to 2.1 and 2.082 times that of the matrix, respectively, in contrast, the addition of nano-SiC makes them increase to 2.4 times and 1.475 times, respectively.
