摘要：

ADC12 is a eutectic Al-Si die-cast alloy (Al-12Si) widely used instead of cast iron for industrial parts in order to reduce their weight. Here, to improve the wear resistance, SiC and diamond particles were dispersed into the surface of the ADC12 alloy. The tribological properties of the hard-particle-dispersed ADC12 samples under lubrication were evaluated using a vane-on-plate tribometer and compared to those of hypereutectic Al-Si alloy (Al-15Si). Three different kinds of vane materials, carbon steel, die steel and high-speed steel, were used as counter materials. The diamond-dispersed ADC12 alloy showed the most significant wear reduction effect when sliding against die steel and high-speed steel, and the lowest coefficient of friction was obtained when high-speed steel was used as the counter material. The durability tests using a conventional pump and the modified materials confirmed the significant improvement in the wear resistance of hard-particle-dispersed ADC12.
