显象管阳极帽是封接在显象管玻璃壳锥体部分的金属零件(如图1)。它的质量如何,对显象管稳定真空度很有影响。由于阳极帽本身以及它与玻璃封接后的密封状态不良而引起的显象管漏气现象,对显象管质量的危害很严重。目前,有关工厂、研究部门,对阳极帽原材料的晶间腐蚀问题和它与玻璃的封接技术进行较多的深入研究。本文着重探讨金属材料在零件成形过程中的穿晶裂纹现象。 Cathode tube anode tube is sealed in the pyramid portion of the glass tube metal parts (Figure 1). Its quality, it has a very strong influence on the stable vacuum of the CRT. Due to the anode cap itself and the sealed state after sealing with the glass, the leak of the CRT results in serious damage to the quality of the CRT. Currently, the relevant factories, research departments, anode cap raw materials, intergranular corrosion and glass sealing technology with more in-depth study. This article focuses on the metal material in the forming process of the part of the transgranular crack phenomenon.
