摘要
用SEM ,XPS对钽及表面离子渗氮层在充分搅拌的 5 0℃的 6 .5 %NaOH中腐蚀前后的表面进行了观察和分析。证明表面腐蚀产物为NaTaO3 和Ta2 O5。结合计算的腐蚀反应的电荷转移数 ,给出了钽在碱液中可能的腐蚀反应方程式。
The surfaces of tantalum and its nitride were investigated by SEM and XPS before and after being corroded in fully stirring 6.5% NaOH solution at 50?℃. The results show that the corrosion products was mainly composed of NaTaO 3 and Ta 2O 5. The corrosion reaction formula has been given according to the corrosion products and the electric charge transfer number calculated. [
