摘　　要：2205双相不锈钢因具有高耐腐蚀性,在进行材料性能评定时,其显微组织很难快速、清晰地显现出来。在现有双相不锈钢腐蚀方法的基础上,采用草酸、碳酸氢钠、硝酸和甘油的配方,对腐蚀液进行优化,运用电解腐蚀的方法,可以在短时间内得到清晰的双相不锈钢显微组织。Due to its high corrosion resistance,it was difficult to quickly and clearly show the microstructure of 2205 duplex stainless steel in the material performance evaluation.On the basis of the existing corrosion methods of duplex stainless steel,the formula of oxalic acid,sodium bicarbonate,nitric and glycerol was used to optimize the corrosion solution,and the clear microstructure of duplex stainless steel could be obtained in a short period time by using the method of electrolytic corrosion.
