摘要: 将不同基材、不同磷含量的化学镀镍磷合金镀层样品在南海海洋大气环境中进行大气暴露试验,观察其腐蚀行为,并进行对比分析,优选出海洋环境耐腐蚀性能好的镀层工艺。结果表明,在海洋大气环境中,高磷镀层比中磷镀层耐腐蚀性能好;Q195基材镍磷合金镀层耐腐蚀性能优于铝基材镀层,而铝基材镀层中,LF6M基材镀层优于LF21M基材镀层,LY12-CZ基材镀层耐腐蚀性能最差;海洋大气环境中的Cl- 是镍磷合金阴极镀层的主要腐蚀原因。

Abstract:The autocatalytic plating nickel-phosphorus coatings with different phosphorus content on different substrates were exposed in marine atmospheric environment of South China Sea. During exposure time, the corrosion behaviors were researched and compared. The testing results showed that the corrosion resistance of coatings with high phosphorus content was better than those coatings with medium phosphorus. The corrosion resistance of coatings on Q195 steel substrate was better than those coatings on aluminum substrate. The coatings on LF6M substrate were better than those coatings on LF21M substrate and the coatings on LY12-CZ substrate were the worst; The Cl- is the primary factor for the nickel-phosphorus cathode coating in marine atmospheric environment.
Key wordsmarine atmospheric environment test    autocatalytic plating    nickel-phosphorus coating    corrosion resistance
