This project which is based on the demand of increasing the electron tube ’ s qualities totally and reducing the manufacture cost has done a large amount of investigative work as follows to improve and perfect the technologies for the important part of electron tube manufacture ? the grid surface processing : on the surface processing of the molybdenum grid , the primary purpose is to reduce thermionic emission and secondary electronic emission of the grid . by the constantly experiment and grabbling the different technology routes , we have successfully developed these new technologies on the tac and zrc electrophoresis and electroplating platinum black of the grid , and made its surface cladding quality very stable and reliable 本課題是基于整體提高電子管的質量和降低生產成本的要求,對電子管生產中的重要部分? ?柵極的表面處理技術進行改進和完善,主要在以下方面進行了深入研究:在鉬柵極表面處理方面,主要為實現降低柵極的熱電子發射和二次電子發射,通過不同工藝路線的不斷試驗和摸索,成功開發出柵極電泳tac 、 zrc和電鍍鉑黑的新工藝,使柵極的涂覆質量穩定可靠。
