摘要
对比研究了碳化硅 ( Si C)、石墨 ( Gr)混杂增强铝硅合金复合材料 ( Al- Si/Si C+ Gr)与铸铁、以及基体铝硅合金的干摩擦磨损性能。 Al- Si/Si C+ Gr显现了优异的耐磨性 ,分别是基体铝硅合金的 6～ 8倍和铸铁的 1～ 3倍。同样 ,其抗咬合性能明显比铸铁好。 Al- Si/Si C+ Gr对配偶钢的磨损非常轻微 ,在 40 N( 1 .44MPa)载荷时配偶钢的磨损分别是铝硅合金基体情况下的 1 /39和铸铁情况的 1 /5。Al- Si/Si C+ Gr-钢摩擦副的总磨损率也很微小。
The tribological property of silicon carbide and graphite particulates reinforced Al Si alloy matrix composite was researched, compared with that of the matrix and that of gray cast iron The composite displays wear resistance 6~8 times higher than the matrix, and 1~3 times higher than gray cast iron The seizure resistance of the composite is also better than that of the gray iron, because seixure ocurred to the gray iron at 40N (1 44MPa) The wear rate of the counterface steel against the composite is just 1/39 of that of the matrix and 1/5 of that of gray iron So the total wear rate of the tribosystem of the composite is much lower than those of the matrix and gray iron
