| Popis: | Due to the many advantages it provides metal matrix composite materials, it is used as a publication in many industrial applications, especially in the automotive industry. Therefore, it is necessary to know the properties of these materials such as mechanical, tribological and corrosion. In this study, the effect of different sliding speeds was investigated on wear behavior of aluminum matrix composite materials produced by adding different amounts of ZrO2 by mechanical alloying method. 4 different amounts (3%, 6%, 9% and 12%) ZrO2 were added to the aluminum 2% graphite matrix. Composite powders mechanically alloyed for 60 minutes, were produced green compact samples by cold pressed with a pressure of 700 MPa. The green compacts produced were sintered for 2 hours at 600 °C. The produced aluminum composites were characterized by microstructure, density and hardness measurements. Wear tests were carried out on a block on-ring type wear testing device, under 20 N load and three different sliding speed (0.2 ms-1, 0.4 ms-1 and 0.6 ms-1) and three different sliding distances (53 m, 72 m and 94 m). As a result of the studies, hardness and density values increased as the amount of ZrO2 in the matrix increased. Wear test results showed that weight loss decreased with increasing amount of reinforcement in the matrix. |
