EFFECT OF HEAT TREATMENT ON WEAR BEHAVIOR OF AlSi10Mg ALLOY FABRICATED BY CASTING

The ease of processing aluminum due to its mechanical and chemical properties, along with various manufacturing methods, has increased its usage in the industry. This study involves tests conducted on the samples produced from EN AC-43000 (AlSi10Mg) aluminum casting material, which finds applications in machine manufacturing. The tests aimed to determine the mass loss and friction coefficients of the test specimens. Wear experiments were carried out according to ASTM G99 using a specialized test machine. The abrasive disc used in the wear machine has a surface hardness of 62 HRC and a surface roughness value (Ra) of 1,6 μm, and it is made of 1,2379-X155CrVMo12-1 cold work tool steel. Adhesive wear tests were conducted on the test specimens under loads of 14,7, 24,5, and 34,3 N. When the mass losses of the samples were examined, the wear rate decreased as the aging temperature increased up to 200 °C. On the other hand, it was observed that the wear rate increased at 220 °C, unlike aging at lower temperatures.
