Thermal spray coatings of new Mo-Ni-B and Mo-Co-B  cermets were developed. These cermet coating have superior properties than carbide cermets(i.e. WC-Co, Cr3C2-Ni/Cr) at high temperature. Thier hardness and oxidation resistance are higher than Cr3C2-Ni/Cr coating having same metal contents at 873-1073K. Especialy, its friction coefficient to steel and glass is low. The mechanism of low friction and other features will be shown in this presentation.
