通过极化扫描,EIS,XRD和SEM技术研究了Gd_(56)Al_(26)Co_(18)和Sm_(56)Al_(26)Co_(18)非晶合金在0.01 mol/L氢氧化钠溶液中的腐蚀行为,同时通过DSC研究了自由体积。非晶合金在0.01 mol的NaOH碱溶液中腐蚀后发现经过重熔处理增加了它的耐腐蚀性能。Gd基非晶条带在0.01 mol/L的NaOH碱溶液中的耐腐蚀性要优于Sm基非晶条带。另外通过研究发现,重熔后的非晶条带含有的自由体积比第1次制备的非晶条带要少。
The effects of Gd_ (56) Al_ (26) Co_ (18) and Sm_ (56) Al_ (26) Co_ (18) amorphous alloys in 0.01 mol / L sodium hydroxide solution were investigated by polarization scanning, EIS, XRD and SEM. In the corrosion behavior, while free space by DSC study. After the amorphous alloy was corroded in 0.01 mol NaOH alkaline solution, it was found that remelting increased its corrosion resistance. The corrosion resistance of Gd-based amorphous strip in 0.01 mol / L NaOH alkali solution is better than that of Sm-based amorphous strip. In addition, it is found through research that the remelted amorphous ribbon contains less free volume than the first prepared amorphous ribbon.
