In this article, 10um, 50um, 110um, 200um and 280um aluminoxide particles were used separatively for producing various roughness metal surfaces. The effects of different roughness of metal surface on porcelain--metal bonding strength were studied by porcelain--metal bonding strength measurement, scanning electron microscope (SEM) observation and energy-dispersive analysis of x-rays (EDAX). The result shows: the size of aluminoxide particles should be over 50 microns for non-precious Ni-Cr allay Surface blasting. In certain range, the roughness of metal surface can increase bonding strength significantly.
在本文中，分别使用了10微米、50微米、110微米、200微米和280微米的氧化铝颗粒来制备各种粗糙度的金属表面。通过测量烤瓷-金属结合强度、扫描电子显微镜（SEM）观察和X射线能谱分析（EDAX），研究了金属表面不同粗糙度对烤瓷-金属结合强度的影响。结果表明：对于非贵金属镍铬合金表面喷砂处理，氧化铝颗粒尺寸应超过50微米。在一定范围内，金属表面粗糙度可显著提高结合强度。
