在这项研究中，我们的目标是监测四种溶液中钛合金（TI6Al4V）的腐蚀行为：盐水溶液、添加1% H2O2的盐水溶液、添加1%白蛋白的盐水溶液和混合1%白蛋白+ 1% H2O2的盐水溶液，以观察这两种化合物联合使用的协同效应。众所周知，H2O2是一种ROS（活性氧），在人体发生炎症反应时产生，白蛋白是人体中最丰富的蛋白质，因此被使用。采用开路电位（OCP）、动电位极化曲线（PD）和电化学阻抗谱（EIS）等电化学测量方法，研究了钛合金（TI6Al4V）在生理盐水、H2O2和白蛋白存在下的腐蚀行为。从电化学结果可以看出，盐水溶液中H2O2的存在降低了TI6Al4V合金的耐腐蚀性，而盐水溶液中白蛋白的存在起到了抑制剂的作用，TI6Al4V合金的耐腐蚀性比添加H2O2的溶液有所提高。
In this study our goal was to monitoring the corrosion behavior of titanium alloy (TI6Al4V) in four solution: saline solution, saline solution with addition of 1% H2O2, saline solution with 1% albumin and saline solution with mixed 1% albumin + 1% H2O2 in order to see the synergistic effects of this two compound in combination. It is known that H2O2 is a ROS (reactive oxygen species) which appear in human body when inflammatory reactions occur and albumin it is used because is a protein (the most abundant) from the human body. In vitro studies for corrosion behavior of titanium alloy (TI6Al4V) in a presence of saline solution, H2O2 and albumin in this study were investigated by different electrochemical measurements: OCP (open circuit potential), PD (potentiodynamic polarization curves) and EIS (electrochemical impedance spectroscopy). From the electrochemical results we can say that the presence of H2O2 in the saline solution decreases the corrosion resistance of the TI6Al4V alloy, while the presence of albumin in the saline solution acts as an inhibitor and the corrosion resistance of TI6Al4V alloy increases as compared to the solution in which it was added H2O2.
