摘要/Abstract

摘要： 通过机械球磨方法在铝合金表面制备了Ni-Al-Mo复合涂层,对涂层微观组织、组成成分和摩擦学性能等进行了分析.结果表明:经过7 h机械球磨制备的Ni-Al-Mo复合涂层内元素均匀分布;550 ℃退火后涂层中均有Al₃Ni金属间化合物新相生成;复合涂层中Al₃Ni和Mo的存在使得涂层硬度高于铝合金基体和Ni-Al涂层,Mo添加质量分数为10%、20%和30%时涂层硬度随Mo含量的增加而增大,分别约为105、125、167 HV;涂层硬度的增大有效降低了涂层磨损率,三种涂层的磨损率约为0.4×10^－3～0.6×10^－3mm³/(N·m);复合涂层优异的摩擦系数和磨损率有效保护了铝合金基体.

Abstract: Ni-Al-Mo composite coating was prepared on surface of aluminum alloy by the method of mechanical milling. And the microstructure of coating,composition and tribological properties of the coating were analyzed. The result show that the elements in the Ni-Al-Mo composite coating are evenly distributed after 7 h mechanical ball milling. After annealing at 550 ℃,new phases of Al₃Ni intermetallic were formed in the coating. The presence of Al₃Ni and Mo in the composite coating makes the coating hardness higher than that of aluminum alloy substrate and Ni-Al coating, the coating hardness increases with the increase of Mo content, and that is respectively about 105 HV, 125 HV and 167 HV at the addition amount of10%, 20% and 30%; The increase of coating hardness effectively reduces the wear rate,and the wear rate of the coating is about0.4×10^－3～0.6×10^－3mm³/(N·m); The excellent friction coefficient and wear rate of the composite coating effectively protect the aluminum alloy matrix.
