Abstract
The tribological properties of K2Ti4O9 whisker reinforced Al-20Si alum inum matrix composites were investigated in a mode of low amplitude re ciprocal sliding. The ball-an-disk tests were performed at applied loa ds of 20-100 N and sliding velocity of 0.09 m s(-1). The water lubrica ted composites demonstrated higher wear resistance and friction coeffi cient than the tetradecane lubricated composites did. The main wear me chanism is microgrooving at low applied loads and tribochemical wear a t high applied loads for the pairs lubricated with water, microgroovin g at an lest loads for the pairs lubricated with tetradecane.
