| 摘 要： | 采用可溶性阳极电刷镀的方法制备纳米晶Ni-Fe合金和纳米晶Ni镀层,用浸泡法和电化学极化法研究了纳米晶Ni、Ni-5.84%Fe和Ni-13.49%Fe镀层在3.5%NaCl和10%HCl溶液中的腐蚀行为.结果表明:通过此法制备的Ni和Ni-Fe合金镀层具有典型的纳米晶结构;随着含Fe量的增加,镀层的晶粒尺寸减小,硬度增加;所制备的纳米晶Ni-13.49%Fe合金镀层组织结构均匀致密,晶界处没有明显的孔洞或缺陷,晶界及三叉晶界处的原子错配度小,过渡均匀,其在3.5%NaCl溶液中的耐蚀性优于纳米晶Ni镀层,而在10%HCl溶液中的耐蚀性与纳米晶Ni镀层相当;纳米晶Ni和纳米晶Ni-Fe合金刷镀层在3.5%NaCl溶液中的腐蚀形态均为点蚀,而在10%HCl溶液中的腐蚀形态则为均匀腐蚀.

| Abstract: | Nanocrystalline nickel and Ni-Fe alloy coatings were synthesized by brush plating using soluble anode. The corrosion characteristics of nanocrystalline nickel, Ni-5.84%Fe and Ni-13.49%Fe alloys were investigated by soak a method and an electrochemical polarization method, respectively. The experimental results indicate that the typical nanocrystalline nickel and Ni-Fe alloy coatings can be synthesized by brush plating, and the alloying element Fe has the effects of solution strengthening and grain size refi... |
