摘要
用俄歇能谱仪对比研究了添加 0 2 %Y对高硅不锈钢在 93%H2 SO4 介质中所形成的钝化膜中各元素浓度分布的影响。添加 0 2 %Y增大了SiO2 在不锈钢钝化膜中的比例 ,从而使合金中Si可充分形成富SiO2 的钝化膜。
The element distribution of passivated film formed on the Y added high silicon stainless steel surface in the 93%H 2SO 4 was studied by AES. The results show that 0 2%Y addition can increases the SiO 2 proportion in the passive film of stainless steel so that it makes the SiO 2 content more rich of passive film in the alloy.
