Abstract

Aluminum powder compacts have low wear resistance due to the reduction in ductility. The ductility enhances using the metalwork technology like the hot extrusion process. The wear test is done using pin on disc machine for all hot extruded aluminum compacted specimen reinforced with 1, 2, 3, and 4 copper wires, and extruded at 450℃. The load is applied by dead weights (1600 gm) at 4 variable linear velocities of 0.628, 0.942, 1.25 and 1.57 m/sec at constant time. The results shown that wear resistance enhances with the hot extrusion process for increasing number of reinforcement copper wires.
