观察陶瓷金相时用哪种腐蚀液比较好？

我是做陶瓷专业的，我们经常做SEM实验，观察陶瓷的表面形貌，主要是晶粒大小和形状等。既然是观察形貌，所以我觉得陶瓷涂层的腐蚀与纯陶瓷的腐蚀是一样的。我们用的腐蚀方法有两个，一个是热腐蚀，一个是化学腐蚀，所用的腐蚀液就是酸类，硫酸、硝酸等，差别就在腐蚀时间上，这个是经验的积累，没有确定的时间规定。腐蚀时间越长，腐蚀程度越大。

希望对你有用。

This study USES three schemes of corn protein biological macromolecules organic templates biological mineralization processes and regulation mechanism. The first one is by ir, XRD, sem observation and analysis, the research of different PH, add ways such as time and mineralization in different conditions on the influence of the mineralization products. The second option is to use two kinds of methods and amide phosphorylation of corn protein microspheres, then modified with modified corn protein microspheres were of hydroxyapatite mineralization. The third is using different methods of preparation of different size radius of corn protein microspheres, and then use the method, the fluid bubble simulation research corn protein of biomimetic mineralization.
