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.
