AlTiN coating has inconspicuous anti-wear effect on carbide.(3) With the introduce of graphite chips bwteen the frictional surface, the effect of graphite chip on the sliding friction and wear behavior of frictional pair was studied. The results show that graphite chips can reduce the coefficient of friction and frictional temperature, and make the coefficient of friction decrease with the decrease of normal load and rise of sliding speed.
