| Abstract: | Sm2Co17 type permanent magnet materials were corroded under three kinds of corrosion conditions.Scanning electron microscopy and energy dispersive X-ray spectrometer were used to study the metallographic corrosion conditions.The result showed that sample corroded for 60 seconds in corrosive liquid of 100ml distilled water dissoled in 0.5ml nitric acid and 2ml acetic acid can clearly display boundary,surface of grain,and Zr-rich and Sm-rich phase in the grain.Compared with the corrosion agent most commonly used to metal material and the formula from metallographic corrosion handbook,the corrosion agent determined in this research can get a more clearly metallographic image. |
