铸造铝合金-石墨颗粒复合材料作为廉价质轻耐磨材料很早就受到人们重视。如同铸铁一样,若能使石墨均匀分布在铝合金中,就可以赋于铝合金前所未有的性能,如低的摩擦系数,低的线膨胀系数以及良好的吸震性、耐磨性、抗咬合性等等。但由于石墨几乎不溶于铝,它在熔融铝中溶解度小于0.05％,同时还由于它与铝的润湿性差(铝 Cast aluminum alloy - graphite particle composite material as a cheap, light and wear-resistant material has long been valued. Like cast iron, if graphite is evenly distributed in aluminum alloy, it can give unprecedented properties such as low coefficient of friction, low coefficient of linear expansion and good shock absorption, wear resistance, seizure resistance, etc. Wait. However, since graphite is hardly soluble in aluminum, its solubility in molten aluminum is less than 0.05%, and at the same time due to its poor wettability with aluminum (aluminum
