本研究的目的是探讨使用电解处理，可以提高镍钛正畸丝的耐腐蚀性，以尽量减少不良反应。在甘油和乳酸组成的溶液中对Ni-Ti丝进行电解处理5、15或30 min。对丝表面进行阳极极化测试、三点弯曲测试和X射线光电子能谱分析，以探索最佳处理条件。处理后的导线的击穿电位随着处理时间的增加和更高的耐腐蚀性，通过进行电解处理超过5分钟，得到的。在层中的镍的相对浓度降低成反比的处理时间。结果表明，对耐蚀性较低的商品镍钛丝进行5 min以上的电解处理，可以提高其耐蚀性。
The purpose of this study was to examine the use of electrolytic treatment, which can improve the corrosion resistance of Ni-Ti orthodontic wires, to minimize adverse effects. Electrolytic treatment of Ni-Ti wires was performed in a solution composed of glycerol and lactic acid for 5, 15, or 30 min. The anodic polarization test, three-point bending test, and X-ray photoelectron spectroscopic analysis of the wire surface were performed to explore an optimal treatment condition. Breakdown potentials of treated wires increased with increasing treatment time and higher corrosion resistance was obtained by performing the electrolytic treatment for more than 5 min. The relative concentration of nickel in the layer was decreased in inverse proportion to the treatment time. The results suggest that the commercial Ni-Ti wire with low corrosion resistance can be improved by the electrolytic treatment for more than 5 min.
