摘要: ＬＴＮＦ常温Ｎｉ－Ｆｅ合金镀层的耐蚀原因分析黄树坤，邹振华，邝少林（湖南大学化学化工系长沙４１００８２）肖觉民，吴力军（湖南大学材料测试中心）１前言通常的瓦特镀镍工艺在常温下得到的镍镀层发暗，应力大且耐蚀性差，不宜作为防护装饰性镀层使用．我们曾提出一种节能、省镍的ＬＴＮＦ常温Ｎｉ－Ｆｅ合金电镀工艺［１］，由该工艺得到的镀层不但光亮，而且应力低，耐蚀性优良，可作为防护装饰性镀层使用．本文报导关?...

Abstract：Ni-Fe electrodeposits obtained at ambient temperature possess superior corrosion resistance. Its cause was experimentally investigated by means of electronmicroscopy and X-ray distraction analysis. The results showed that both low-iron (5～7Wt%) and high-iron (20～25wt%) alloy deposits were homogeneous nickel-base solid solutiolls. In these deposits lower internal stress, smaller grain size and (100) texture me those obtained in the Watts nickel electrodeposit were obserVed. Besides, a lamellar structure composed of iron-rich and iron-depleted zones alternately made up a galvanic corrosion system which may prevent the underneath steel substrate from corrosion.
