碱性无氰锌合金电镀工艺 COLLOY NI-Z-POSIT
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7.5-15g/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
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 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:
- 镀层含镍量 10-15%
- 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 锌镍合金工艺,请致电美国哥伦比亚化工。
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 alkaline plating process produces a bright, ductile (high nickel) zinc-nickel deposit that is ideal for meeting today's demanding automotive specifications:
- 10 - 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... and call Columbia Chemical.
