【摘要】 在钢基化学镀Ni-P镀层上再电镀上1层镍,成功制得Ni-P+Ni双镀层,并对Ni-P镀 层和Ni-P+Ni双镀层进行可靠性试验,结果表明Ni-P+Ni双镀层表面光亮,其致密性和可靠 性都比Ni-P镀层好,对提高金属抗蚀性和防护性有着重要的意义。更多还原

【Abstract】 The reliability of substrate steel coated with a electroless Ni-P deposit and a electrolytic nickel layer is investigated. The results show that double layers deposit has a glaorous surface, and its compaciness and reliability are better than Ni-P deposit, which is very important for metals to improve their erosion resisrance and barrier properties.更多还原
