Abstract

The bond strength of porcelain to the four gold alloys and the three nonprecious alloys was tested with a simplified pull test method, having wide test surfaces. The tests showed that all gold alloys tested were suitable for fusing porcelain. The bond strength in nonprecious alloys was somewhat lower and the location of the fracture lines was more variable. It seems that nonprecious alloys are more sensitive to laboratory procedures. The bond strength and the location of the fracture line had a good correlation in all metal alloys.

摘要

采用具有宽测试表面的简化拉伸试验方法，测试了瓷与四种金合金和三种非贵金属合金的结合强度。测试表明，所有测试的金合金都适合熔附瓷。非贵金属合金的结合强度略低，断裂线的位置变化更大。似乎非贵金属合金对实验室操作更敏感。在所有金属合金中，结合强度与断裂线位置具有良好的相关性。
