中文摘要:
      目的 研究电镀黑铬的耐候性,对汽车行业的黑铬应用风险进行评估。方法 通过对比分析的方法,以传统电镀亮铬性能为参照,从耐腐蚀、耐氙灯老化、自然暴晒三个方面介绍汽车用装饰性电镀黑铬的耐候性,并对黑铬耐候性不良的原因进行分析、讨论。结果 电镀黑铬的耐自然暴晒性能、耐腐蚀性能均较传统亮铬差,镀层自钝化效果差镀层氧化是影响镀层耐候性的主要因素。结论 电镀黑铬不适合应用于汽车外饰零部件。
英文摘要:
      Objective To research the weather resistance of black chromium plating and assess the risk of its application in the auto industry. Methods Based on comparative analysis from the following three aspects: resistance to corrosion, xenon lamp aging and natural exposure, the weatherability of automotive decorative black chromium plating was analyzed and discussed by referring to performance of traditional bright chrome plating. Results Black chromium plating had poor resistance of natural exposure and corrosion. The poor self-passivation was the main factor which influenced the coating weatherability. Conclusion Black chromium plating is not suitable for automotive exterior parts.
