本文着重研究了B~+、P~+离子在不锈钢S.S.316L和Ni二种金属中的低温注入。对样品表层进行了电子衍射结构分析和阳极极化曲线,线性极化阻力(R_P)的电化学腐蚀性能测定。结果表明B~+、P~+离子注入使这两种金属的抗腐蚀性能明显改善,尤其在注入表面形成非晶态结构时,其抗腐蚀性能有显著的提高;并且在二次离子质谱分析所得到的注入离子浓度分布与在同一样品上进行多次阳极极化曲线所显示抗腐蚀性能之间存在着对应关系。即注入表面离子浓度高峰的地方其抗电化学腐蚀的稳定性也较好。
This article focuses on the B ~ +, P ~ + ions in the stainless steel S.S.316L and Ni two kinds of low-temperature metal injection. Electron diffraction structure analysis and anodic polarization curve were performed on the sample surface. The electrochemical corrosion resistance of linear polarization resistance (R_P) was measured. The results show that the corrosion resistance of these two metals is obviously improved by B ~ +, P ~ + ion implantation, especially when the amorphous structure is implanted into the surface, and the corrosion resistance of the two metals is improved remarkably. In the secondary ion mass spectrometry There is a correspondence between the resulting ion concentration distribution and the corrosion resistance exhibited by multiple anodic polarization curves on the same sample. That is injected into the surface of the ion concentration peak where the resistance to electrochemical corrosion stability is better.
