Five Ni-Cr alloys were studied in order to identify the compounds formed on the alloy surface during oxidation under conditions similar to those encountered during dental laboratory procedures prior to application of porcelain. After the alloys were oxidized, the films covering the surfaces were removed with the aid of a Br-methanol solution. X-ray diffraction was used to analyze the compounds formed. Oxides of nearly all elements contained by the alloys were found after low-temperature (650 degrees C) oxidation, while NiO and particularly Cr2O3 were predominant after oxidation at high temperatures (1000 degrees C).
研究了五种镍铬合金，以便确定在类似于牙科实验室烤瓷前操作条件下合金氧化过程中在合金表面形成的化合物。合金氧化后，借助溴 - 甲醇溶液去除覆盖在表面的薄膜。使用X射线衍射分析形成的化合物。低温（650摄氏度）氧化后发现了合金所含几乎所有元素的氧化物，而在高温（1000摄氏度）氧化后，氧化镍尤其是三氧化二铬占主导地位。
