Notes:
The tribological behavior and the mechanism of nano-silicate mineral powder aslubrication oil additive were researched in the article. The tribological behavior of nano-silicatemineral powder with mass ratio 0.6% in lubrication oil 50CC was tested and compared with thelubrication oil 50CC’s by friction wear testing machine. The surface morphologies and elementarycompositions of grinding cracks were analyzed by Scanning Electron Microscope (SEM) and EnergyDispersive Spectrometer (EDS).The results showed that the friction coefficient is decreased 37.5%,and the lost mass of the upper proof sample reduces 68.75%, the down’s reduces 86.7%, after addingnano-silicate mineral as lubrication oil additive, by comparison to lubrication oil 50CC’s. Under thelubrication oil which has been putted nano-silicate mineral as additive, there is a repairing layerwhose material is different from basal body material on the grinding cracks; in addition, Si, Mg andother elements are deposited on the repairing layer. These state that nano-silicate mineral aslubrication oil additive possesses superior behavior of wear resistance, antiwear and self-repairingeffects
