镀层的抗腐蚀能力,尤其是做为防护性镀层的抗腐蚀能力,是镀层性能的一个重要指标。槽镀中,常见的铬、镍、锌、金、银等镀层在一般环境中具有较好的抗腐蚀能力;刷镀中,由于镀层质量较高,孔隙卒较低,可供选择的单金属镀层和合金镀层种类很多,因而,可获得更多更好的耐腐蚀镀层。如低氢脆镉、铟或铟锡合金等刷镀层具有优良的抗盐水腐蚀性能,银、铟、铜、铑、金等叠加镀层具有更高的耐蚀性。尽管一些
Anti-corrosion coating capacity, especially as a protective coating corrosion resistance, coating performance is an important indicator. Groove plating, the common chromium, nickel, zinc, gold, silver and other coatings in the general environment has good corrosion resistance; brush plating, due to the higher quality coating, lower porosity, the choice of single metal Coating and alloy coating a wide range of types, thus, get more and better corrosion-resistant coating. Such as low hydrogen embrittlement cadmium, indium or indium tin alloy brush coating has excellent corrosion resistance of salt water, silver, indium, copper, rhodium, gold and other superimposed coating with higher corrosion resistance. Although some
