Tribological Properties Research of Nano-electro-brush Plating In Layer in Vacuum Radiation Environment

Making use of nano-electro-brush plating technology,the layer In was prepared on working lining.With scanning electron telescope(SEM) and X-ray diffraction(XRD),surface,grinding crack pattern and elemental composition of In layer after exposed in air,in vacuum,atomic oxygen and ultraviolet radiation are analyzed.Vacuum friction and wear equipment model CZM was applied for testing tribological properties under dry friction condition in environments such as air,vacuum,atomic oxygen and vacuum ultraviolet radiation.Outcome shows in normal state,metal In has good chemic stability,erosion resistance and solid lubricity and the atomic oxygen and vacuum ultraviolet’s effect on it is very limited.But the tribological properties of lubricant coating prepared with nano-electro-brush plating technology are poor because of degradation of density and superficial smoothness caused by air-bleeding.So as long as through proper process method and enhancing In layer’s forming quality,soft metal In coating should have decent prosperity in future space equipments and arming.
