摘要
研究了C +Mo +C注入结构和相变 ,用多重扫描电位法研究了其抗腐蚀特性 ,得出了抗腐蚀相生成的条件 ,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 +C双注入H13钢中 ,可有效地提高H13钢的抗腐蚀性 ,并能提高点蚀电位 ,使之更耐点蚀 .三重注入生成了含Fe2 Mo ,FeMo合金相和MoC ,Fe5C3,Fe7C3,Mo和MoO等的表面钝化膜 .这种钝化膜的存在可提高H13钢的耐腐蚀性和抗点蚀特性 .其抗腐蚀和抗点蚀特性优于单注入和双注入 .这种多重注入最可贵之处在于既可提高钢表面的抗点蚀特性 。
The influence of multi implantation on the corrosion resistance of H13 steel was studied using multi sweep cyclic voltammetry. The formation conditions of phases and its effects on corrosion resistance were studied. The mechanism of improvement in corrosion resistance was discussed. The experimental results show that the increase of Mo dose can improve corrosion resistance, however the increase of C dose can enhance pitting corrosion potential. Both effects were obtained using dual and multi implantation. The passivation layer consists of the phases of Fe 2Mo, FeMo, MoC, Fe 5C 3 and Fe 7C 3 in dual implantation surface of steel. It can improve corrosion resistance and increase pitting corrosion potential. Multi implantation can further improve corrosion and pitting corrosion resistance compared with dual implantation.
