In this paper, the corrosion resistance of laser-welded composite arch wire (CoAW) with Cu interlayer between NiTi shape memory alloy and stainless steel wire in artificial saliva with different concentrations of protein was studied. It was found that protein addition had a significant influence on the corrosion behavior of CoAW. Low concentration of protein caused the corrosion resistance of CoAW decrease in electrochemical corrosion and immersion corrosion tests. High concentration of protein could reduce this effect.
本文研究了 NiTi 形状记忆合金与不锈钢丝之间具有 Cu 中间层的激光焊接复合弓丝(CoAW)在不同浓度蛋白质人工唾液中的耐腐蚀性能。结果表明,蛋白质的添加对 CoAW 的腐蚀行为有显著影响。低浓度蛋白质会降低 CoAW 在电化学腐蚀和浸泡腐蚀测试中的耐腐蚀性,而高浓度蛋白质则可以降低这种影响。
