Experimental Study on Electrolytic Oxidation of Metal Halide Lamp Electrode

The inner liner of metal halide lamp is mostly composed of transparent quartz glass and component electrode seal. According to the wettability principle of glass to metal, before sealing, it is oxidized into low-cost metal oxide on the electrode surface of metal halide lamp by electrolytic oxidation, so as to solve the problem of permanent sealing of two different materials. The metal halide lamp electrode 70/100 W was selected as the research object, and the electrolytic oxidation treatment experiment was conducted. Through orthogonal experiments and data analysis, the four experimental parameters of electrolyte hydrochloric acid content, electrolytic voltage, electrolytic current, and electrolysis reaction time and their interaction on the quality of the oxide layer were studied. A digital microscope was used to observe the quality of the surface oxide layer, and air leakage detection was performed after sealing. The experimental results show that a layer of low price oxide is produced on the metal surface by electrolytic oxidation, which can form a firm air tight seal between glass and metal.
