摘要

The laser-melting process of SiC nano-particles coated on the plasma sprayed WC-Co coating was performed. The SiC nanocomposite coating was prepared, and the microstructure and the mechanical properties of it were investigated. After laser irradiated, parts of nano SiC particles are turned into the inner of coating with the nano-micro composite structure. The being of SiC nano-particles in coating brings the better fine microstructure and the higher densification. The wear-resistant property and the corrosion-resistant property of the coating with SiC nano-particles are improved more than the coatings prepared by laser melting process without the SiC nano-particles.
