摘要
用多次扫描电位法研究了金属Mo和Ti与C离子双注入和 2种元素注入的顺序对抗腐蚀特性的影响 ,研究了抗腐蚀纳米相生成的条件 ,首次观察到细丝状纳米碳化物镶嵌相的形成 ,以及这些相对抗腐蚀特性的作用 ,并对其改性机理进行了讨论 .扫描电子显微镜观察表明 ,抗腐蚀的细丝状纳米碳化物镶嵌相与双注入的注入次序有密切的关系 ,这种相仅出现在碳为最后的双注入中 .特别可贵的是这种细丝状纳米碳化物镶嵌相也能有效地提高抗点蚀特性 .
The influence of multi implanted H13 steel on corrosion resistance is studied using multi sweep cyclic voltammetry. The formation conditions of wire nano phases against corrosion resistance and its effects on corrosion resistance are researched. The mechanism of improvement in corrosion resistance is discussed. The experimental results show that the formation of wire nano phases is closely related to dual implantation order. If C implantation is following metal ion implantation, the wire nano phases can be formed in steel. It is very important that wire nano phases can improve both corrosion resistance and tipping corrosion resistance.
