The purposes of this study were to investigate the corrosion properties and the surface structure of ion implanted nickel-titanium orthodontic wire. Ion implanted nickel-titanium wire and Non ion implanted nickel-titanium wire were used for a potentiodynamic polarization measurement and X-ray photoelectron spectroscopy (XPS). Ion implanted wire in artificial saliva and mouthrinse with neutral pH had a lower current density than non ion implanted wire. Both wires in mouthrinse with low pH showed similar corrosion properties. XPS results suggested that a TiN layer may be present on the top surface. Plasma immersion ion implantation might increase the corrosion resistance of nickel-titanium wire in a neutral environment because of a protective TiN layer on the top surface.

本研究的目的是研究离子植入镍钛正畸丝的腐蚀特性和表面结构。离子注入镍钛丝和非离子注入镍钛丝用于动电位极化测量和X射线光电子能谱（XPS）。离子植入线在中性pH值的人工唾液和漱口水中的电流密度比非离子植入线低。两种电线在低 pH 值的漱口水中表现出相似的腐蚀特性。 XPS 结果表明，顶表面可能存在 TiN 层。由于顶表面有保护性的 TiN 层，等离子体浸没离子注入可能会提高镍钛丝在中性环境中的耐腐蚀性。
