  1. 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

    本課題是基於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，使柵極的塗覆質量穩定可靠。
