金相组织的显示最常用的方法是化学浸蚀和电解浸蚀。也有用物理方法借助金属本身的力学、电学或磁性能显示金相组织。如热蚀、阴极真空溅射或磁性显示等等。铌、锆、钛等有色金属合金的阳极氧化法相分析,即将试样接于直流电源的阳极,以有机酸(草酸、柠檬酸、乳酸或磷酸等)为电解质(图1),利用电化学反 The most commonly used methods of metallographic display are chemical etching and electrolytic etching. It is also useful to use physical methods to show the microstructure with the mechanical, electrical or magnetic properties of the metal itself. Such as thermal etching, cathode sputtering or magnetic vacuum display and so on. Niobium, zirconium, titanium and other non-ferrous metal alloy anodic oxidation phase analysis, the sample will be connected to the DC power anode, with organic acids (oxalic acid, citric acid, lactic acid or phosphoric acid, etc.) as the electrolyte (Figure 1)
