碱性锌镍合金电镀白钝化工艺的研究

Studies on white chromating of zinc-nickel alloy electrodeposited from alkaline bath

研究了不同镍含量的锌镍合金镀层低铬白钝化工艺。通过中性盐雾试验 ,比较了不同钝化工艺对不同镍含量的锌镍合金镀层耐蚀性的影响。结果表明 。

Low chromium white chromating for zinc-nickel alloy deposits with different nickel contents was studied. Influence of different white chromating processes on corrosion resistance of zinc-nickel alloy deposits with different nickel contents were studied by meams of NSS test. Results show that different white chromating processes should be separately used for zinc-nickel deposits with different nickel contents.
