用多次扫描电位法研究了C +Mo双注入和两种元素注入的顺序对抗腐蚀特性的影响 ,研究了抗腐蚀相生成的条件 ,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 .实验结果表明 ,在C+Mo双注入H1 3钢中 ,生成了含Fe2 Mo,FeMo合金相和MoC ,Mo2 C ,MoCx ,FeMo2 C ,Fe2 C ,Mo和MoO等的表面钝化膜 .双注入则具有C和Mo单注入双重优点 ;可有效地提高H1 3钢的耐腐蚀性和抗点蚀特性 ;效果比Mo单注入更好 ,与C +Mo双注入注入次序相反的Mo+C双注入生成的钝化膜抗腐蚀性更强 .特别可贵的是这种注入能有效地提高抗点蚀特性 .
The effect of the order of C + Mo double implants and the implantation of two elements on the corrosion resistance was studied by multiple scanning potential methods. The conditions of anti-corrosion phase formation were studied. The formation of filamentous nanocrystalline inlay phase was observed, and these Relative corrosion resistance and the modification mechanism are discussed.The experimental results show that Fe2Mo, MoC2, MoCx, MoCx and FeMo2 are formed in H1 + C, Fe2C, Mo and MoO etc. The double injection has the dual advantages of single injection of C and Mo, which can effectively improve the corrosion resistance and pitting corrosion resistance of H1 3 steel. The effect is better than single injection of Mo The passivation film formed by Mo + C double implantation with the opposite injection order of C + Mo is more resistant to corrosion, and it is especially valuable that such implantation can effectively improve the anti-pitting property.
