摘要

采用低压冷喷涂技术在AZ91D镁合金基体上制备了Ni含量不同的Cu-Ni-Al₂O₃复合涂层。采用扫描电子显微镜和X射线衍射仪分析了复合涂层的微观形貌和结构;通过显微硬度、结合强度和摩擦磨损试验研究了复合涂层的力学性能。结果表明:Cu-Ni-Al₂O₃复合涂层结构致密,涂层未发生氧化和相变。控制合适的Ni含量可降低涂层的孔隙率,提高涂层的沉积效率、结合强度和耐磨性。当Ni含量为21%(质量分数)时,Cu-Ni-Al₂O₃复合涂层的孔隙率为0.94%,沉积效率为36.32%,结合强度为26.31MPa,体积磨损率为1.10×10^-11m³/m。

Abstract

Cu-Ni-Al₂O₃ composite coatings with different Ni contents were prepared on AZ91D magnesium alloy substrates using low-pressure cold spraying technology.The micro-morphology and the structure of the coatings were analyzed by SEM and XRD.The mechanical properties of the coatings were studied through microhardness,bond strength,and friction-wear tests.The results showed that the Cu-Ni-Al₂O₃ composite coatings exhibited a dense structure without oxidation or phase transformation.The porosity of the coatings could be reduced and their deposition efficiency,bond strength,and wear resistance could be improved by controlling the amount of Ni.When the Ni content was 21% (mass fraction),the Cu-Ni-Al₂O₃ composite coating exhibited a porosity of 0.94%,a deposition efficiency of 36.32%,a bond strength of 26.31MPa,and a volume wear rate of 1.10×10^-11m³/m.
