Copper-matrix/graphite（pure graphite/nickel-coated graphite） composites were prepared by sintering specimen in an atmosphere of N

2

and H

gas mixture. The effects of nickel coating on tribological

corrosive behavior and resistivity

hardness of the copper-matrix/graphite composites were investigated. The results indicate that nickel coating can significantly improve the interface bonding strength between copper-matrix and graphite. During the process of friction

graphite particles are difficult to be stripped out of the wear surface

so as to form a continuous and complete solid lubrication film

improving the wear reduction and wear resistance of the composites. Compared with that of pure graphite copper matrix composites

the wear rate of nickel-coated graphite composites can be reduced by about 70% under the same test conditions

which is increased gently with the increase of wear pressure. In addition

the existence of nickel in the coating can also enhance the hardness and corrosion resistance of the composites.
