چکیده انگلیسی
Composite plating was used to prepare Ni-W infused rare earth oxide CeO2 composite coatings. The high temperature friction behavior and corrosion resistance of the coatings against molten glass were investigated by using a high temperature tribometer. A microhardness tester and an environmental scanning electron microscope equipped energy dispersive spectroscopy were employed to investigate the microhardness and the surface morphology of the composite coatings respectively. The results show that the brittle fracture, high temperature tribological properties and the corrosion resistance of Ni-W infused CeO2 coatings are superior to those of a standard Ni-W coating. CeO2 particles decrease the friction coefficient from nearly 0.5 to about 0.25 during the composite coatings sliding against the molten glass at about 973Â K, and proper quantities of CeO2 decrease the variation of the friction coefficient value. Furthermore, CeO2 can improve the corrosion resistance of the Ni-W coatings at high temperature effectively.
