作者应用俄歇电子能谱仪,对显象管所用的基金属进行了表面分析。发现基金属中的激活元素Mg、Si、A1、Ca等在表面存在着一个“富集层”。在“富集层”中激活元素的浓度,远远大于其体内的平均浓度。用对比法初步找到了形成“富集”的原因。对基金属的分析还发现钨在基金属表面恰恰又形成一层“贫钨层”。在洁净的基金属表面很容易吸附C,在高达70～90％的表面碳往往会把微量激活元素淹没。
The author applied Auger electron spectroscopy to conduct a surface analysis of the metal used in the kinescope. Found that the activation of the metal elements Mg, Si, Al, Ca and so there is an “enrichment layer” on the surface. The concentration of activated elements in the “enriched layer” is much greater than the average concentration in the body. With the contrast method initially found the formation of “enrichment” reason. Analysis of the metal also found that tungsten forms a “lean tungsten layer” on the surface of the metal. In the clean metal surface is easy to adsorb C, up to 70 ~ 90% of the surface carbon tends to submerge the trace elements.
