Fe-Me(Me=Co,Ni,Co-Ni)合金化层表面钝化膜的电化学行为
Electrochemical Behavior on Surface Passivation Films of Fe-Me(Me=Co,Ni,Co-Ni) Alloying Layers
摘 要
采用热扩渗方法在低碳钢表面制备了Fe-Co、Fe-Ni和Fe-Co-Ni合金化层。热扩渗过程在1 000 ℃的纯H2气氛中进行,处理时间为5 h。采用XRD、EDS和SEM对合金化层的组成和微结构进行了测试,并采用电化学手段分析了合金化层在硼酸缓冲溶液(pH=8.4)中的钝化行为。结果表明,合金化层均为单一α-Fe固溶体相; Fe-Ni合金化层以及镍含量相对高的Fe-Co-Ni合金化层表面易于形成致密的钝化膜; 这些钝化膜可以明显改善低碳钢基体在碱性溶液环境中的耐蚀性。

Abstract
Fe-Co, Fe-Ni and Fe-Co-Ni alloying layers were prepared on mild steel by thermal diffusion. Heat treatment of the coated mild steel was performed at 1 000 ℃ for 5 h in hydrogen atmosphere. The composition and microstructure of the alloying layers were analyzed by XRD, EDS and SEM. A series of electrochemical analysis was carried out to examine the passivation behavior of these alloying layers in borate buffer solution (pH=8.4). Results indicated that the Fe-Ni alloy layer and the Fe-Co-Ni alloy layer with high Ni content promoted the formation of compact passive films. The passive films significantly improved the corrosion resistance of mild steel substrate in alkaline solution.
