摘　　要：金卤灯内胆大多由透明的石英玻璃与组件电极密封组成。根据玻璃与金属的润湿性原理,在封接前,通过电解氧化的方法在金卤灯电极表面氧化成低价的金属氧化物,解决两种相异材料的永久封接问题。选用金卤灯电极70/100 W为研究对象,进行电解氧化处理实验研究。通过正交实验以及数据分析,研究电解液盐酸含量、电解电压、电解电流、电解反应时间4种实验参数及其交互作用对氧化层质量的影响。利用数显显微镜观察表面氧化层质量,并在封接后进行漏气检测。实验结果表明:运用电解氧化方法在金属表面产生一层低价氧化物,能使玻璃与金属形成牢固的气密封接。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.
