| 摘 要： | 利用化学法对1Cr18Ni9钢表面扩渗稀土，通过X－射线衍射分析了试样表面的组织状态。结果表明，1Cr18Ni9钢渗入稀土后，表面有CeFe7和LaO新相产生，并引起奥氏体含量降低，铁素体含量增加，改变了试样表面的微观结构。阳极极化曲线的测定结果表明，扩渗稀土后的1Cr18Ni9钢试样耐腐蚀性能超过了稳定化处理的1Cr18Ni9Ti钢水平。

Influence of Rare-earths Gas-phase Permeation Treatment on the Surface Corrosion Resistance of 1Cr18Ni9 Steel |

| Abstract: | Rare earths was permeated on the surface of 1Cr18Ni9Ti steel by the chemical method. Then the composition and structure of the surface were investigated by the X ray diffraction. The results showed that after the treatment some new phases were formed, and austenite contents increased and ferrite contents decreased on the surface of 1Cr18Ni9 steel; Anode polarization test confirmed that its corrosion resistance exceeded that of stabilized 1Cr18Ni9Ti steel. |
