【摘要】 对碱性化学镀 Ｎｉ－Ｐ／ＣｅＯ_２复合镀层的工艺参数进行了研究．并与化 学镀 Ｎｉ－Ｐ镀层的耐水溶液腐蚀和耐高温腐蚀性能进行了比较研究。通过对镀层表 面形貌、结合力以及ＣｅＯ_２复合量的测量，确定出最佳镀液配方和施镀参数。实验 结果表明，Ｎｉ－Ｐ／ＣｅＯ，复合镀层具有良好的耐蚀性能。其原因主要是由于弥散分布 的稀土ＣｅＯ２颗粒改善了镀层的微观结构，并在腐蚀过程中表现出稀土元素所起 的效应。更多还原

【Abstract】 Alkaline electroless Ni-Pr-CeO₂composite coating was studied.The corrosion behavior of Ni-P-CeO₂ composite coating in aqueous H₂SO₄ （0.5M） solution and in high temperature environment was studied and compared with electroless Ni-P coating. By testing the surface morphology,adhesion and CeO₂ content of the composite coating. optimal parameters were determined in the coating process.It was found that microstructure of the coating was im- proved due to CeO₂ composition,and anti-corrosion properties was improved due to rare earth effects.更多还原
