在将瓷熔合到金属基材上的过程中，合金上的氧化物被瓷的玻璃相溶解。理论上已经讨论了形成键所需的溶解程度，但事实证明很难获得氧化物厚度和溶解度的测量值。在本研究中，使用俄歇分析确定了 Ni−Cr 合金/玻璃对的界面成分。这些样品由熔合有 5 种专有 Ni−Cr 合金的玻璃纽扣组成。用 10% Br-甲醇溶液溶解合金后，对玻璃进行分析。氧化物中元素的扩散分布表明玻璃对氧化物的溶解不完全。在合金/氧化物界面处也发现了大量的硅。
During fusion of porcelain onto metal substrates, oxides on the alloy are dissolved by the glassy phase of the porcelain. The extent of solution needed for development of a bond has been discussed in theory, but measurements of oxide thickness and solubility have proven difficult to obtain. In this study, the interfacial compositions of Ni−Cr alloy/glass couples were determined using Auger analysis. The samples consisted of buttons of glass fused to 5 proprietary Ni−Cr alloys. After dissolution of the alloy by a 10% Br-methanol solution, the glass was analyzed. The diffusion profiles of elements in the oxide indicated incomplete dissolution of the oxide by the glass. High amounts of silicon were also found at the alloy/oxide interface.
