摘　　要：Zn-Ni合金涂层技术是近年发展起来的防腐涂层新技术,与锌涂层相比,该涂层具有十分优异的腐蚀防护性能。随着工业的发展,Zn-Ni合金涂层将会成为锌的替代性涂层,在钢铁腐蚀防护领域得到广泛应用,极具发展前景。文中介绍了用电镀、热浸镀、热喷涂和渗镀的方法制备Zn-Ni合金涂层的主要进展情况,讨论了Zn-Ni合金涂层的腐蚀防护机理,指出了今后应把开发Zn-Ni合金基材作为Zn-Ni合金涂层技术获得突破的关键,把开发Zn-Ni复合涂层作为扩大Zn-Ni合金涂层应用的手段,同时应加强对Zn-Ni合金涂层耐腐蚀机理的研究,为Zn-Ni合金涂层技术的研究和应用提供理论指导。The way of forming Zn-Ni alloy coating is a newly developed anticorrosive technology.The corrosion resistance of the Zn-Ni alloy coatings is better than that of unalloyed zinc,which shows a trend of substituting for zinc coatings and will be widely applied in the areas of steel protection.In this work,the recent development of the study on preparing Zn-Ni alloy coatings by electroplating,hot dipping,thermal spraying and diffusion are reviewed.The anti-corrosion mechanism of the Zn-Ni alloy coatings is discussed.The preparation of Zn-Ni basic alloy is the key work for the development of Zn-Ni alloy coating.The exploration of newly Zn-Ni composite coatings is the approach for the breakthrough of application;meanwhile,the research on the anti-corrosion mechanism of Zn-Ni alloy coatings should be further intensified to provide guidance for the research and application of the zinc-nickel alloy coatings.
