Current Statues of the Wear Resistance of Electroless Ni-P Based Alloy Plating

化学镀镍磷基合金镀层因硬度高、厚度均匀及耐磨性优异,在工业中得到了广泛应用。简述了化学镀镍磷基合金从二元、三元到复合镀层的发展历程,概述了化学镀镍磷基合金镀层耐磨性的影响因素——合金镀层的化学成分、镀层与基体间的结合力及镀层硬度,并从这三方面论述了改善耐磨性的方法,最后提出了在改善合金镀层耐磨性研究中存在的问题和未来的发展方向。

Electroless Ni-P based alloy platings have found extensive application in industry because of its high hardness, uniform thickness and excellent wear resistance. The development of the electroless Ni-P based alloy platings, from binary and tenary alloy coatings to composite coatings, was summarized, and the influence factors of the wear resistance were presented from the chemical composition of alloy coating, the combining power between coating and matrix and the hardness of coating, as well as current status of improving the wear resistance of electroless plated Ni-P based al- loys. At last, the problem exiting in the research of improving the wear resistance of alloy coating and the future research orientation were raised.
