Abstract
The invention relates to the technical field of aluminum alloy automobile parts, in particular to a reinforced abrasion-proof composite aluminum alloy automobile part blended with basalt fibers and a casting technology thereof. According to composite materials of the part, the basalt fibers with surfaces being coated with nano-carbon sol are added to conventional aluminum alloy materials. The basalt fibers treated in this way keep complete structural characteristics. Moreover, nano-carbon adheres to the surfaces of the basalt fibers, so that the wettability of the basalt fibers in molten metal is improved. The treatment method is simple and efficient. The use performance of the materials is improved more efficiently. The prepared alloy materials have better overall mechanical properties and are resistant to pressure and abrasion. The part cast through the alloy materials has the advantages of being light and durable in use and has good application prospects.
