以２０２４铝合金为基体，使之与硅线石颗粒搅融混合成均匀浆料，经半固态挤压成形，获得一种新型的复合材料制件。对它进行摩擦磨损性能测定后发现，虽然增强体硅线石颗粒是直接从矿石开采获得的，但由于采用搅融混合半固态挤压新技术，其耐磨性明显高于ＺＱＳｎ６－６－３铜合金。为此，对其摩擦学特性进行了研究，以便为硅线石颗粒作为一种廉价的增强剂应用提供依据。 Taking 2024 aluminum alloy as substrate, the mixture was mixed with sillimanite particles to form a homogeneous slurry, which was extruded into a semi-solid state to obtain a new type of composite material. The results of friction and wear tests showed that although the reinforced sillimanite particles were directly obtained from ore mining, the wear resistance of the composite was obviously higher than that of ZQSn6-6- 3 copper alloy. To this end, tribological properties have been studied in order to provide a basis for the application of sillimanite particles as an inexpensive enhancer.
