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。

Abstract:
The way of forming ZnNi alloy coating is a newly developed anticorrosive technology. The corrosion resistance of the ZnNi 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 ZnNi alloy coatings by electroplating, hot dipping, thermal spraying and diffusion are reviewed. The anticorrosion mechanism of the ZnNi alloy coatings is discussed. The preparation of ZnNi basic alloy is the key work for the development of ZnNi alloy coating. The exploration of newly ZnNi composite coatings is the approach for the breakthrough of application; meanwhile, the research on the anticorrosion mechanism of ZnNi alloy coatings should be further intensified to provide guidance for the research and application of the zincnickel alloy coatings.
