摘　　要：为提高钨钩针的使用寿命,采用电解抛光的方法对报废钨钩针进行再生处理。本文探究了氯化钠溶液与深度共晶溶剂对报废钨钩针的抛光效果并对再生钨钩针的耐腐蚀性能进行了测试。结果发现,使用氯化钠溶液抛光后表面光洁平整,而深度共晶溶剂抛光后表面会碳化变黑。增加电化学数据,如腐蚀电位等,发现两种抛光液抛光后的钨钩针耐腐蚀性均显著提高,氯化钠溶液的抛光后的耐腐蚀性能效果最好。氯化钠溶液可以有效代替传统电解溶液对钨钩针进行再生处理并且绿色无污染。To improve the service life of tungsten barb needles,end-of-life tungsten barb needles are regenerated by electrolytic polishing.This paper investigates the effect of sodium chloride solution and deep eutectic solvent on the polishing of end-of-life tungsten barbs and tests the corrosion resistance of the regenerated tungsten barbs.It was found that the surface was smooth and clean after polishing with the sodium chloride solution,while the surface was carbonized and blackened after polishing with the deep eutectic solvent.Adding electrochemical data,such as corrosion potential,it was found that the corrosion resistance of the tungsten crochet hooks after polishing with both polishing solutions was significantly improved,with the sodium chloride solution giving the best results in terms of corrosion resistance after polishing.The sodium chloride solution is an effective alternative to conventional electrolytic solutions for the regeneration of tungsten barbels and is green and non-polluting.
