一、工艺特点
提供光亮、无脆性、高中低电流密度区分布均匀的锌镍合金镀层,镀层含镍量为10%-15%
适当钝化处理后,锌镍合金镀层的耐腐蚀性能大大超过镀锌层
锌含量工艺范围为7-9g/L,锌含量控制更加灵活
不需要单独的整流器或向镀液中补充镍的阳极
可接受非银基黑色钝化,也能接收黄色钝化和银基黑色钝化
二、高性能的汽车电镀要求最佳的工艺。哥伦比亚化工让你掌握主动,应对需求。美国哥伦比亚化工的 COLLOY NI-Z-POSIT-II 碱性锌镍合金电镀工艺,能产生非常光亮,延展性好(含镍量高)的锌镍合金镀层,是满足当今汽车行业技术规范的理想选择:
三、镀层含镍量 13-15%
最适用于车盖下面接触到高温的零件,例如空调零件,油管,紧固件,刹车部件等
在所有的电流密度区,镍分布和厚度都非常良好和均匀
符合最严格的耐蚀性测试要求
所以当你想到锌镍合金,请想到 COLLOY NI-Z-POSIT-II 锌镍合金工艺,请致电美德耐化工。
High performance automotive plating demands the very best processes. Columbia Chemical can put you in the driver's seat. Columbia's COLLOY NI-Z-POSIT-II alkaline plating process produces a bright, ductile (high nickel) zinc-nickel deposit that is ideal for meeting today's demanding automotive specifications:
13 - 15% nickel in the deposit
Perfect for under-the-hood components that come into contact with high heat, such as air conditioning components, fuel lines, fasteners and brake components
Best, most uniform thickness and nickel distribution across all current density areas
Meets the most severe corrosion test requirements
So when you think zinc-nickel, think COLLOY NI-Z-POSIT-II... and call METALITE Chemical.
