摘要
研究了新型的代铬合金镀层Ｎｉ－Ｆｅ－Ｗ－Ｐ－Ｓ进行了耐腐蚀性能。结果表明：在ＮａＣｌ体系中代铬镀层的耐蚀性是铬层的１．７倍、镍层的５．２倍；在Ｈ２ＳＯ４体系中，代铬镀层的耐蚀性是铬层的１．４倍、镍层的２．７倍．用扫描电镜（ＳＥＭ）、Ｘ射线衍射及光电子能进（ＸＰＳ）等的分析表明，基体组织为非晶结构是代铬镀层优异耐腐蚀性的主要原因．
The corrosion resistance of new type of chromiumsubstitute brush plating depositsNi-Fe-W-P-S has been studied. The results show that in NaCl solution, the corrosion resistance ofNi-Fe-W-P-S increases by a factor 1.7 and 5.2 in comparision to chromium and nickel depositsrespectively; and in H2SO4 increases 1 .4 and 2.7 respectively.The results of examines by Scanning Electron Microscope (SEM), Transmission ElectronMicroscope(TEM), Scanning Tunneling Microscope(STM), X-Ray diffractor and X-Ray PhotoelectronSpectrometry (XPS) show that the excellent corrosion resistance of the chromiumsubstitute brush plating deposits may be attributed to the amorphous features of the deposits.
