摘要
对15CrMo钢和12Cr1MoV钢的快速金相制样方法进行了探索,确定了一种磨抛光侵蚀剂法。结果表明:采用由25mL蒸馏水、30mL双氧水、2mL氢氟酸和2g草酸配置的磨抛光侵蚀剂,在室温下侵蚀试样约60s,能够清晰地显示出15CrMo钢和12Cr1MoV钢的显微组织;该方法具有操作简单、耗时少、不受部件位置和形状限制等优点,可极大地提高现场金相制样的效率。
The rapid preparing method for metallographic specimens of 15 CrMo steel and 12 Cr1 MoV steel was explored,and the grinding and polishing erosion reagent method was determined.The results show that：after etching in the grinding and polishing reagent consisting of 25 mL distilled water,30 mL hydrogen peroxide,2 mL hydrofluoric acid and 2 g oxalic acid for 60 sat room temperature,the microstructure of 15 CrMo steel and12 Cr1 MoV steel could be revealed clearly;the method had the advantages of easy handling,less time consumption and no restrictiveness of locations and shapes,and the efficiency of in-filed preparation for metallographic specimens could be enhanced greatly.
