重熔处理对铝基非晶合金腐蚀性能的影响

Influence of Remelting Treatment on Corrosion Behavior of Amorphous Alloys

摘要:

通过极化扫描,EIS,XRD和SEM 技术研究了Gd56Al26Co18和Sm56Al26Co18非晶合金在0.01 M氢氧化钠溶液中的腐蚀行为,同时通过DSC研究了自由体积。发现非晶合金经过重熔处理后能增加它的的耐腐蚀性能。

Abstract:

The corrosion behavior of Gd56Al26Co18 and Sm56Al26Co18 amorphous alloys in 0.01 M NaOH solution had been researched by polarization scanning, EIS technique, XRD and SEM. The free volume was also investigated by DSC technique. It was found that the corrosion resistance of amorphous alloys increased after remelting.
