摘要/Abstract

摘要： 目的：通过用失晶粗化的方法对金属底层进行处理，以提高金属烤瓷的结合强度。方法：采用不同形态（球形、长方体、立方体）、不同粒度（直径0.1、0.2和0.3 mm）、不同比例晶体含量在30%、50%和80%的晶体盐(NH₄Cl,NaCl和KMnP₄)，制作蜡型常规包埋铸造合金烤瓷后，测试金属烤瓷合金抗拉强度、剪切强度、抗压强度。结果：不同形态的晶体以球形晶体盐(NH₄Cl)为佳；不同粒度的晶体盐(NH₄Cl)以直径0.2 mm粒度为佳；不同比例的晶体盐(NH₄Cl)以50%含量的晶体盐为最佳。结论：失晶粗化的方法处理金属的烤瓷合金的结合强度显著提高。

Abstract: Objective To improve metal-porcelain interfacial bond strength through treating the metal bottom with wiping crystal off and roughening it. Methods Crystals (NH₄Cl,NaCl and KMnP₄) with different shapes (globose, rectangular, cubical)，different granularitis（the diameter of 0.1,0.2, and 0.3 mm）and different proportions (the respective content of crystal in which was 30%,50%, and 80%) were chosen.After wax pattern was shaped,routinely imbedded ,casted and fused ,the drawing strength ,the cut strength,and the pressing strength were tested. Results The crystal (NH₄Cl) with globose shape was the best of the three shapes;the crystal (NH₄Cl) with the diameter of 0.2 mm was better than the other two and the content of 50% of crystal was the most appropriate proportion in the three kinds of crystal. Conclusion This method can improve the metal-porcelain interfacial bond strength greatly.
