Friction and wear properties of SiC and immerse copper graphite(C/Cu) against stainless steel (1Cr18Ni9Ti) friction couples were studied under room temperature and unlubrication by pin-disc tribometer. The test shows that at sliding speed of 0.56ms-1 and normal load of 5N, 20N, the SiC/1Cr18Ni9Ti friction coefficient decreases. The immerse copper graphite shows good friction and wear behavior at load 50N, at which the copper of graphite matrix is transported to the surface from the pore of graphite matrix to form a couple of copper and copper. It is difficulties to measure volume loss. When load increased, the copper was transported to generate the film and was grinded away continuously, which the immerse copper graphite(C/Cu) volume loss increases at load 120N. The results of comparing two couples show volume loss of the couple SiC/1Cr18Ni9Ti is severe, so it is not suitable to combine a couple. The couple of immerse copper graphite (C/Cu)/1Cr18Ni9Ti is better applied at low load.
