%X Using HT200 gray iron as the lower sample, the sliding friction and wear behavior of laser cladding in situ synthesis TiC p/Al composite surface layers containing different volume fractions of TiC particle were tested on a type MM 200 ring block wear tester. The experiment results show that as the volume fraction of TiC particles is less than 20%, the wear amount of the composite decreased with the increase in the fraction. At a volume fraction above 25%, the larger the fraction is, the more the wear amount will be. Compared with the materials DL7 and ZL104, the composite layer containing 20% TiC has a wear volume loss of 26.7% of that of DL7 and 56.5% of that of ZL104. However,the incorporation of TiC of various volume fractions almost has no influence on the friction coefficient.
