FeNi_(42)Cr_6A1玻封合金是大量用于显象管的阳极帽材料,与玻壳锥体封接后,作为引进管内高压的阳极。 金属与玻璃在封接过程中,合金表面氧化膜质量的优劣是保证封接强度和可靠气密性的重要因素之一,而合金的予氧化工艺则是生成优质表面氧化膜所必不可少的条件。 本文为讨论予氧化温度、表面机械加工处理、大气中高温封接过程的再氧化作用对合金表面氧化膜的影响分别进行了模拟试验、对所得试样用俄歇扫描微探针(SAM)进行合金主要元素Fe、Ni、Cr的浓度及其深度测试,分析,并讨论了所得结果,为合理选择予氧化工艺提供参考依据。
FeNi_ (42) Cr_6A1 glassy sealing alloy is a large amount of anode cap material used for the picture tube. After sealing with the glass bulb cone, the FeNi_ (42) Cr_6Al glass is used as the anode for introducing the high voltage inside the tube. Metal and glass in the sealing process, the quality of the oxide film on the surface of the alloy is to ensure that the sealing strength and reliable air tightness is one of the important factors, and the alloy is the oxidation process is essential to generate high-quality surface oxide film is essential conditions of. In this paper, we simulate the effects of reoxidation on the oxide film on the surface of the alloy under the conditions of oxidation temperature, surface mechanical processing, atmospheric high temperature sealing process, respectively. The obtained sample was subjected to Auger scanning microprobe (SAM) The main elements of Fe, Ni, Cr concentration and depth of the test, analysis, and discussed the results obtained for the rational choice of oxidation process to provide a reference.
