摘要: 镀液中的稀土元素对Ｎｉ－Ｐ合金镀层耐蚀性能的影响邵光杰，王玉林，沈德久，于金库（燕山大学材料工程系秦皇岛０６６００４）１前言电刷镀Ｎｉ－Ｐ合金镀层作为设备的局部防护处理手段已经得到了广泛应用。但单纯的Ｎｉ－Ｐ合金镀层还不能满足某些部门的要求，进一步提高镀层的耐蚀性能已引起表面处理工作者的注意［１］。本工作研究稀土在电刷镀Ｎｉ－Ｐ合金镀层中的作用。２实验方法基础镀液中的镍离子含量为６０ｇ／Ｌ，?...

Abstract：The effect of rare earth addition to brush plating bath on structure and corrosion resistance of electrodenosited Ni－P alloy layer was studied．The results showed that the addition of 1g／L of blent rare earth could promote non-crystallization of the resulting Ni－P（RE）alloy layer，which was amorphous with even as low as only 5％ P．The Ni-P (RE) alloy had higher corrosion resistance than Ni-P alloy without rare earth in 3．6％ HCl solution and sea water．A mechanism of improvement was proposed．The rare earth ions might be adsorbed on the eledrode surface and interfered with normal discharge and diffusion of Ni2+ so as to promote the non-crystallization.
