中文摘要	Ni-W-CeF3 composite coatings were prepared by electrodeposition in a Ni-W plating bath containing CeF3 nano-particles. The shape and size of the CeF3 nano-particles and the surface topography of the composite coatings were observed using an environmental scanning electron microscope, and the component and structure analysis was characterized by means of XRD. A microhardness tester was employed to investigate the microhardness of the coatings. The high temperature friction behavior and corrosion resistance of the coatings against molten glass were investigated by using a high temperature tribometer. It was found that the CeF3 nano-particles appeared in the coatings as microspheres of a diameter less than 50 nm. The addition of CeF3 nano-particles led to changes in morphologies of the composite coatings by refining the size of crystalline bulks. Therefore, the Ni-W-nanoCeF(3) composite coatings had more compact and fine granular morphologies. The co-deposited CeF3 nano-particles were uniformly distributed in the Ni-W matrix and had contribution to greatly increasing the microhardness, high temperature tribological and anti-corrosion properties of the Ni-W alloy, furthermore the mechanism of anti-friction and anti-corrosion is discussed.
