摘　　要：主要研究并分析了不同工艺下的锌-镍合金镀层及不同厚度镀层的防腐性能。结果表明,不同工艺防腐性能优劣顺序为:电镀+钝化+封闭>电镀+钝化>电镀+封闭>电镀,随厚度增加,镀层防腐性能提高,δ为8~12μm的锌-镍合金镀层在保证生产效率的前提下,具有良好的防腐性能,且产品具有良好的粘合性能。Anti-corrosion performance of different processes and thickness of Zn-Ni alloy coatings were researched and analyzed. Results showed that the anti-corrosion performances order of the different processes, in accordance with their pros and cons,was as following ： electroplating ＋ passivation ＋ seal- ing 〉 electroplating ＋ passivation 〉 electroplating ＋ sealing 〉 electroplating, and the anti-corrosion per- formance would increase with the thickness increasing. On premise of ensuring production efficiency, the Zn-Ni alloy coating with 8- 12 μm thickness had good anti-corrosion performance, and the product had good adhesion performance.
