摘要/Abstract

摘要： 零件存储是真空微波器件制造的基础条件,慢波组件一般存放于真空柜中,存放一段时间后,慢波组件中的螺旋线镀铜表面出现了发黑现象,分析表明螺旋线表面镀铜部位发生了硫化。结合进一步的实验研究和理论分析,真空柜中放置的橡胶制品导致了无氧铜材料表面发黑。在真空状态下,硫是比较容易从橡胶套中升华进入真空柜中的,从而会在真空柜中弥漫大量硫蒸气,这些硫蒸气极易与铜发生化学反应形成Cu₂S,因此含硫的橡胶套不宜放入真空柜,并且在真空电子器件中也要防止使用含硫的橡胶制品接触无氧铜零件。

Abstract: The storage of metal parts is the basic condition for the microwave vacuum devices. Slow wave components are generally stored in vacuum cabinets. After storage for a period of time, blackening occurs on the copper plating surface of the helix in the slow wave component. The analysis showed that the copper plating on the surface of the helix was vulcanized. Combined with further experimental research and theoretical analysis, the rubber products placed in the vacuum cabinet caused the surface blackening of the copper material. In the vacuum, sulfur is relatively easy to sublimate from the rubber sleeve into the vacuum cabinet, which will diffuse a large amount of sulfur vapor in the vacuum cabinet. These sulfur vapor easily reacts with copper to form Cu₂S, so the sulfur-containing rubber sleeve should not be placed in a vacuum cabinet, and the use of sulfur-containing rubber products in vacuum electronic devices should be prevented from contacting copper parts.

Key words: microwave vacuum devices, slow-wave structures of helix, copper, storage
