Abstract

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.

摘要

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。
