In this study, the effect of Ti and Zr elements with equal mass ratio on microstructure and corrosion resistance of Zn‐11Al‐3Mg alloy was investigated. The microstructure was significantly refined and Al‐rich phase transformed from dendrite to petal‐like with the addition of Zr and Ti elements, due to the Al3(TixZr1 − x) phase as the nucleation substrate. The corrosion resistance of Zn‐11Al‐3Mg‐x(Ti,Zr) alloy was effectively improved. Moreover, the corrosion products of Zn‐Al‐Mg alloy were not changed by the addition of Ti and Zr, which are mainly composed of Zn5(OH)8Cl2·H2O and Zn6Al2(OH)16CO3·4H2O.

相同质量比的Ti和Zr元素对Zn-11Al-3Mg合金的组织和耐蚀性的影响
在这项研究中，研究了等质量比的Ti和Zr元素对Zn-11Al-3Mg合金的组织和耐蚀性的影响。由于以Al 3（Ti x Zr 1- x）相为成核基质，因此在添加Zr和Ti元素后，微观组织得到了显着改善，富Al相从枝晶转变为花瓣状。Zn-11Al-3Mg- x（Ti，Zr）合金的耐腐蚀性得到了有效提高。此外，通过添加主要由Zn 5（OH）8 Cl 2 ·H 2 O和Zn 6 Al组成的Ti和Zr不会改变Zn-Al-Mg合金的腐蚀产物。2（OH）16 CO 3 ·4H 2 O.
