摘要

通过电化学试验研究了Fe3+对钛在不含F−和含F−的H2SO4溶液中腐蚀的影响。电化学测试结果表明，Fe3+通过促进钛表面保护膜的形成，可以显著抑制钛在没有F−和有F−的H2SO4溶液中的腐蚀。钛的耐腐蚀性（Rc）与不含F−和含F−的H2SO4中Fe3+的浓度呈正相关。提出了Fe3+抑制钛在H2SO4溶液中腐蚀的机理。

Influence of Fe3+ on titanium corrosion in H2SO4 solutions without and with F−

Abstract Influence of Fe3+ on the corrosion of titanium in H2SO4 solution without F− and with F− was investigated by electrochemical tests. The electrochemical test results showed that Fe3+ could significantly inhibit titanium corrosion in H2SO4 solution without F− and with F− by promoting the protective film formation on titanium. Titanium corrosion resistance (Rc) was positively related to the concentration of Fe3+ in H2SO4 without and with F−. A mechanism was proposed for Fe3+ inhibiting the corrosion of titanium in H2SO4 solution without and with F−.

期刊介绍： Corrosion Reviews is an international bimonthly journal devoted to critical reviews and, to a lesser extent, outstanding original articles that are key to advancing the understanding and application of corrosion science and engineering in the service of society. Papers may be of a theoretical, experimental or practical nature, provided that they make a significant contribution to knowledge in the field.
