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.

这项研究的目的是研究离子植入镍齿齿线的腐蚀特性和表面结构。离子植入的镍钛线和非离子植入的镍钛金属丝用于电位动力学极化测量和X射线光电光谱法（XPS）。人造唾液中的离子植入线和具有中性pH的嘴巴的电流密度低于非离子植入线。嘴中的两条电线都具有低pH值的腐蚀特性。 XPS结果表明，顶部表面可能存在锡层。血浆浸入离子植入可能会在中性环境中增加镍丝电线的耐腐蚀性，因为顶部表面有保护性锡层。
