Method of manufacturing a cathode for cathode ray tubes

摘要

The invention relates to a method of manufacturing cathode skirts of low power electron guns comprising a thermal annealing step in which a realisation step of surface irregularities on the outer face of each skirt is provided, before the said thermal annealing. According to one embodiment of the invention this step comprises a chemical attack of the skirts to treat by annealing. Applications: Television tubes
