|
摘要
目的探索不同类型的蛋白对合金抗腐蚀能力的影响及其机制,以期为镍钛和不锈钢弓丝在临床上的安全应用及表面改性提供参考。方法采用动电位极化法测试纤维蛋白原、IgG或黏蛋白对镍钛和不锈钢弓丝抗电化学腐蚀能力的影响,并用循环极化法检测三种蛋白处理后表面钝化膜的修复能力。电感耦合等离子体发射光谱法(inductively coupled plasma optical emission spectrometer, ICP-OES)测定腐蚀产物的类型,并对腐蚀后表面形貌进行扫描电镜和原子显微镜分析。结果添加纤维蛋白原、IgG或黏蛋白对同一合金的抗腐蚀能力影响不同。添加蛋白能够降低不锈钢合金的抗腐蚀能力,可减缓镍钛合金的腐蚀进程。添加黏蛋白能够提高镍钛合金抗腐蚀性和表面钝化膜的修复能力。与黏蛋白及IgG相比,纤维蛋白原能够降低镍钛和不锈钢合金的抗点蚀能力。结论不同类型的蛋白能与弓丝发生作用,在表面形成不同的沉积形貌,并参与合金的腐蚀过程。
Objective To explore the influence and mechanism of different types of proteins on the corrosion resistance of alloy to provide a reference for the safe application and surface modification of nickel-titanium(Ni-Ti) and stainless steel bow wires in the clinic.Methods The effects of fibrinogen, IgG and mucin on the electrochemical corrosion resistance of Ni-Ti and stainless steel arch wires were tested by the potentiodynamic polarization method, and the repair ability of passive films on surfaces treated with the three proteins were tested by the cyclic polarization method.Inductively coupled plasma optical emission spectrometry(ICP-OES) was used to determine the types of corrosion products, and the surface morphology after corrosion was analyzed by scanning electron microscopy(SEM) and atomic forcemicroscopy(AFM).Results The addition of fibrinogen, IgG or mucin to an alloy has different effects on its corrosionresistance. Adding protein can reduce the corrosion resistance of stainless steel alloys and slow the corrosion process of Ni-Ti alloys. The addition of mucin can improve the corrosion resistance of Ni-Ti alloy and the repair ability of passive film. Compared with mucin and IgG, fibrinogen can reduce the pitting resistance of Ni-Ti and stainless steel alloys.Conclusion Different types of proteins interact differently with the arch wire, form different deposition morphologies on the surface, and participate differently in the corrosion process of the alloy.
