Five base metal alloys were investigated to determine if phase changes in the alloy microstructure occurred as a result of the porcelain baking procedure. It was found that during the oxidation treatments concentration changes in the alloy surface led to a depletion of certain elements in four of the alloys investigated. It was also found that phase changes could occur in a region 20 micrometers wide next to the alloy surface. Phase changes and alloying element depletion occurs as a result of the oxidation treatments prior to the fusion of porcelain and not as a result of or during porcelain fusion.
研究了五种贱金属合金，以确定合金微观结构中的相变是否是由于烤瓷程序而发生的。结果发现，在氧化处理过程中，合金表面的浓度变化导致了所研究的四种合金中某些元素的耗尽。还发现，在合金表面旁边20微米宽的区域内可能会发生相变。相变和合金元素的耗尽是由于烤瓷熔合之前的氧化处理而发生的，而不是由于烤瓷熔合期间或烤瓷熔合的结果。
