英文摘要: In the present study, an investigation into wear properties has been carried out to identify the influence of ZrO2 as the reinforcement material on the LM25 MMC composite. Aluminum LM25 is selected as the base material, and it is reinforced with varying proportions of 0, 3, 6, 9, 12 and 15% of zirconia (ZrO2) manufactured by stir casting. Six tensile test and wear test samples were prepared according to the ASTM B-557-M-94 and ASTM G99 standards. Then, the prepared samples were subjected to the wear test using a pin-on-disc wear tester by varying the parameters such as loads of 10 N, 20 N and 30 N and sliding distances of 1,000 m, 1,200 m and 1,400 m for various percentages of ZrO2 reinforcement composites, and corresponding wear losses were measured. The wear test results reveal that an...
