摘　　要：采用电化学分析手段,研究了钛在20、40、60和80℃甲酸溶液中的电化学腐蚀行为。结果表明,在不同温度的甲酸溶液中,钛均能在表面生成具有保护作用的钝化膜;随甲酸溶液温度的升高,钛的耐蚀性能明显降低,腐蚀速率明显加快。The electrochemical corrosion behavior of Ti in formic acid solution at 20 ℃,40 ℃,60 ℃ and 80 ℃ was investigated by electrochemical methods.The results show that the protective passive film can form on its surface at different temperatures.While increasing temperature of formic acid solution,the corrosion resistance property of Ti decreases and its corrosion rate obviously increases.
