本文根据焊接不锈钢髓内针使用的特殊条件和特殊要求,通过对四种方案筛选和浸蚀试验考核,确定了与众不同的电解疏松黑皮+光亮浸蚀+电解抛光工艺,使得经本工艺处理的焊接不锈钢髓内针表现出突出的耐腐蚀特点。同时进行了问题讨论及抛光机理探讨,列出典型工艺,简述了临床应用概况,指出了本工艺的特殊性及通用性,得出了初步结论。 Based on the special conditions and special requirements of stainless steel intramedullary needles, this paper determined the distinctive electrolytic loose black leather + bright etching + electrolytic polishing process through screening and etching tests of the four schemes, Treated welded stainless steel intramedullary needles exhibit outstanding corrosion resistance. At the same time, the discussion of the problem and the polishing mechanism were discussed. The typical technology was listed. The clinical application was briefly introduced. The particularity and versatility of the process were pointed out. The preliminary conclusions were drawn.
