摘要:
锌镍合金镀层具有良好的耐蚀性，在汽车、航空、航天等领域有广泛应用。然而，加热除氢工序可能会造成锌镍合金钝化膜破坏，从而大幅降低镀层的耐蚀性。为了探究加热除氢后锌镍合金镀层的应用可靠性，采用电化学测试及盐雾测试等方法对除氢后的锌镍合金镀层进行了耐腐蚀性测试，对比了腐蚀前后的微观结构变化，探究了除氢后锌镍合金镀层结合力和耐蚀性等的变化情况。实验结果表明，经过加热除氢处理后的锌镍合金镀层在经过96 h盐雾测试后发生了表面腐蚀，但并未完全裸露基体。
Abstract:
Zn-Ni alloy coatings are widely used in automotive, aviation, aerospace and other fields because of excellent corrosion resistance. However, the thermal dehydrogenation process causes damage to the passivation film of Zn-Ni alloy, thereby greatly reducing the corrosion resistance of the coating. To explore the application reliability of Zn-Ni alloy coating after heating and hydrogen dehydrogenation, electrochemical test and salt spray test are used to test the corrosion resistance of Zn-Ni alloy coating after hydrogen dehydrogenation. The changes of microstructure before and after corrosion are compared, and the changes of binding force and corrosion resistance of Zn-Ni alloy coating after hydrogen dehydrogenation are explored. The experimental results show that the Zn-Ni alloy coating after heat dehydrogenation treatment has surface corrosion after 96 h salt spray test, but the substrate is not completely exposed
