[The effect of different size of aluminoxide for sandblasting on bonding strength of porcelain to metal].
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.
