在对磷酸二氢钾(KDP)晶体进行磨削加工的基础上,利用光学显微镜、ZYGO三维表面形貌仪和扫描电子显微镜对KDP晶体磨削加工表面层缺陷及损伤进行了研究,发现磨削加工后的KDP晶体表面有较大的划痕和脆性破碎现象,材料以脆性去除为主。
Processing KDP crystal with grinding method, the optic microscope, ZYGO three- dimensional surface profile measurement, scanning electron microscope were used to study the surface defection and damage analysis of ground KDP crystal. The results show that the materials remove with brittleness wipe off mainly, and have great nick and brittleness crash on the surface of gound KDP crystal.
