Mechanical behaviour of Al 6061/Garnet Particulate Composites

摘要

An attempt has been made to Investigate the tribological behavior of A16061 ceramic particulate reinforced composites. A pin on disc wear testing machine was used to cany out the tribological tests on both composites and matrix alloy over a load range of 10-50N and sliding velocities of 1.25 to 3.05 m/s for various sliding distances of 0.5 to 3 km. A theoretical model was developed for estimating the sliding wear-rate taking into consideration the effect of factional heat on the wear properties at contact surfaces, the effect of reinforcement, mechanical-load, sliding distance, sliding velocities on wear rates, coefficient of friction, and transition wear. An addition of ceramic particulate to A16061 showed that it not only delays the transition wear but also reduces the wear rate.
