摘要
用光学显微镜、维氏硬度计和摩擦磨损试验机对Zn-2Al-x Mg(x=0、0.5、1.0、1.5,质量分数,%)合金镀层的显微组织、硬度和摩擦性能进行了观察分析。结果表明,随Mg含量增加,合金镀层晶粒细化,硬度提高。在相同载荷下,随Mg含量增加,4种合金镀层的摩擦因数相近,耐磨时间先增加后减小,其中含1%Mg的合金镀层耐磨时间最长。Zn-2Al-1Mg合金镀层的耐磨性优于Zn-2Al合金镀层。
Microstructure, hardness and tribological properties of Zn-2Al-xMg (x=0, 0.5, 1.0, 1.5wt%) alloy coatings were observed and characterized with optical microscopy , Vickers hardness tester and friction testing machine .It was found that with increase of Mg content in the hot-dipped galvanizing solution , grain size of the alloy coatings decreases , and the hardness increases .Under the same load , with increase of Mg content , friction coefficient of the four alloy coatings is very close , and wear-resisting lifetime of the alloy coatings increases fist and then decreases , and the longest wear-resisting lifetime is obtained in the alloy coating with 1.0%Mg.The abrasive resistance of Zn-2Al-1Mg alloy coating is superior to that of Zn-2Al alloy coating.
