【摘要】 用XPS、AES研究了可伐合金分别经1:1:8体积比的盐酸——硝酸——水溶液,1:1:1.5:6.5体积比的盐酸——硝酸——丙三醇——水溶液处理后的表面组成、表面层原子价态和表面元素深度分布,并探讨了混合强酸中可伐合金的腐蚀行为。更多还原

【Abstract】 The components and element depth distribution of kovar alloy surface treated in HCl-HNO3 -H2O solution (1:1: 8v/v) and HC1-HNO3-glycerin-H2O solution (1 : 1 : 1. 5 : 6- 5 v/v) respectively have been investigated with XPS and AES methods. The corrosion behaviour of the alloy in the mixed strong acids is discussed.更多还原
