| Abstract: | The metallographic microstructure and surface morphologic structure of graphite brush impregnated silver after wearing test were observed by using SEM. The effects of microstructure of brush on electric conductivity and friction and wear were analyzed. Results show that the silver has efficiently permeated into the porous graphite and appears in the form of network in the matrix. the brush possesses with good electric conductivity and fine lubrication. From the point of view of tribology, the interface of different friction essentiality during the brush sliding contact was analyzed, the wear mechanism of graphite brush impregnated silver was also discussed. |
