中文摘要本发明公开了一种短弧灯钨电极的激光冲击延寿方法,利用去离子水将工件清洗后用干燥的氮气吹干,然后放入100℃的干燥箱中干燥10min;接着在钨电极工作端面覆盖吸收层吸收激光能量防止激光烁伤钨电极表面;接着将钨电极安装在工作台上并在吸收层上施加一层约束层约束激光冲击波增加冲击力;接着以脉宽为3‑40ns、波长为532nm或1064nm、激光能量为0.5‑20J、重复频率为0.1‑10Hz、光束直径为0.5‑10mm的激光束进行预冲击延寿处理和冲击延寿处理;接着去除钨电极工作端面涂覆的吸收层;最后利用去离子水清洗后用干燥的氮气吹干留作短弧灯组装。本发明延寿方法工艺简单,延寿效果显著、效率高、成本低、无污染。
英文摘要The invention discloses a laser shock life-prolonging method of the tungsten electrode of a short-arc lamp. The method comprises: cleaning a workpiece with deionized water, blow-drying the workpiece with nitrogen, and placing the dried workpiece in a drying box at the temperature of 100 degrees centigrade to dry the workpiece for 10 minutes; covering the operating end face of the tungsten electrode with an absorption layer to adsorb laser energy in order to prevent the laser from damaging the surface of the tungsten electrode; installing the tungsten electrode on a workbench and applying a constraint layer to the absorption layer in order to constrain an increase in the shrck force of a laser shock wave; performing pre-impact life-prolonging treatment and impact life-prolonging treatment by using a laser beam with a pulse width of 3 to 40ns, a wavelength of 532 or 1064nm, laser energy of 0.5 to 20J, repetition frequency of 0.1 to 10Hz, a laser beam diameter of 0.5 1o 10mm; removing the absorption layer coating the operating end face of the tungsten electrode; cleaning the workpiece with deionized water and blow-drying the workpiece with dry nitrogen in order to assemble the short-arc lamp. The laser shock life-prolonging method is simple in technology, obvious in life-prolonging effect, high in efficiency, low in cost, and little in pollution.
