A specially designed stainless steel split die capable of producing a total of 24 half cylindrical shaped wax patterns was used in this study. The burnishability of two non-precious casting alloys was evaluated following a proposed softening heat treatment technique. A practical easily applied burnishing tool was introduced. Results have shown that, both of the non-precious alloys were burnishable following softening heat treatment. However, nickel-chromium alloy was significantly more burnishable than the cobalt-chromium alloy. It is suggested that clinical implications of the developed technique in this study would be an important additive for more precision castings.
本研究使用了一种特别设计的不锈钢分体模具，该模具能够制作总共24个半圆柱形蜡型。按照一种提议的软化热处理技术，对两种非贵金属铸造合金的可打磨性进行了评估。介绍了一种实用且易于应用的打磨工具。结果表明，两种非贵金属合金在软化热处理后都具有可打磨性。然而，镍铬合金的可打磨性明显高于钴铬合金。建议本研究中所开发技术的临床意义将成为提高精密铸件质量的一项重要补充。
