失晶法粗化金属表面提高金属—塑料结合强度的研究

Improvement of metal-resin retention strength by roughing metal surface with lost crystals

金属—塑料的界面结合强度关系到修复体的远期效果。失晶粗化法是利用廉价的可溶性晶体盐陷入蜡铸型表面内,失晶后再铸出有粗化表面的金属修复体,用以增加其与塑料结合强度。结果经统计学分析具有科学性。

Metal-resin retention strength has a long-range effect on repair.Roughi- ng surface with lost crystals means that soluble crystal sault is filled into the surface of wax casting mould raising metal-resin retention strength.The stati- stic result shows it is scientific.
