干摩擦条件下超声流变压铸高铁过共晶Al-Si合金磨损性能研究
|
摘要
采用销盘式摩擦磨损试验机对干摩擦条件下超声流变压铸成形Al-17Si-2Fe-2Cu-1Ni-0.8Mn合金的磨损性能进行了研究.结果表明:在相同载荷下,超声流变压铸试样的磨损率比液态压铸试样小.长板条状δ-Al4(Fe,Mn)Si2相的细化以及气孔的消除使得合金的耐磨性能得以提高.当载荷从50 N增至100 N时,液态压铸和超声流变压铸试样的磨损率增幅均较大;当载荷从100 N增至150 N时,磨损率增幅变缓;当载荷从150 N增至200 N时,磨损率增幅又变大.合金在低载荷(50 N)时,磨损机理以氧化磨损为主;当载荷介于100~150 N之间时,以氧化磨损和剥层磨损相结合的方式为主;在高载荷(200 N)时,以剥层磨损为主.
The dry sliding wear tests of Al-17Si-2Fe-2Cu-1Ni-0.8Mn alloy produced by rheo-diecasting(RDC) process assisted with ultrasonic vibration were carried out over a pin-on-disk wear tester. The results show that the wear rate of the RDC alloy was lower than that of the alloy produced by liquid die casting(LDC) process under the same applied load. The refinement of coarse plate-like δ-Al4(Fe, Mn)Si2 phase and the elimination of porosities improved the wear resistance of RDC alloy. The wear rates of the LDC and RDC alloys increased sharply from 50 N to 100 N and from150 N to 200 N. For the LDC and RDC alloys, oxidation wear was the dominant mechanism at 50 N. From 100 N to150 N, oxidation wear and delamination wear were the main wear mechanism. At 200 N, delamination wear was the dominant wear mechanism.
