研究铁含量对流变铸造过共晶Al?17Si?2Cu?1Ni合金在干摩擦条件下磨损行为的影响。磨损测试是在销?盘式摩擦磨损试验机上进行的。结果表明，在同等载荷下，流变铸造合金试样比传统重力金属型铸造试样的磨损率小。细小颗粒状δ-Al4(Fe,Mn)Si2相和多边形状α-Al15(Fe,Mn)3Si2相有助于提高流变铸造合金的耐磨性。随着细小富铁相体积分数的增加，流变铸造合金试样的磨损率减小。此外，随着载荷从50增大至200 N，流变铸造合金试样的磨损率增大。对于含3% Fe的流变铸造合金，在低载荷(50 N)时，磨损机制以氧化磨损为主；在高载荷时，磨损机制以氧化磨损和剥层磨损的联合作用为主。
The effect of iron content on wear behavior of hypereutectic Al?17Si?2Cu?1Ni alloy produced by rheocasting process was investigated. The dry sliding wear tests were carried out with a pin-on-disk wear tester. The results show that the wear rate of the rheocast alloy is lower than that of the alloy produced by conventional casting process under the same applied load. The fine particle-likeδ-Al4(Fe,Mn)Si2 and polygonalα-Al15(Fe,Mn)3Si2 phases help to improve the wear resistance of rheocast alloys. As the volume fraction of fine Fe-bearing compounds increases, the wear rate of the rheocast alloy decreases. Moreover, the wear rate of rheocast alloy increases with the increase of applied load from 50 to 200 N. For the rheocast alloy with 3% Fe, oxidation wear is the main mechanism at low applied load (50 N). At higher applied loads, a combination of delamination and oxidation wear is the dominant wear mechanism.
