摘　　要：在复杂环境下,钛合金表现不仅需要具有良好的耐磨性能,同时还须具有耐酸介质的腐蚀能力。采用电化学和侵蚀等分析手段,研究了钛表面无氢渗碳试样在HCl溶液和H_2SO_4溶液中的电化学特性及浸泡腐蚀性能。结果表明:经过无氢渗碳处理的纯钛试样在HCl和H_2SO_4溶液中的耐蚀性能得到大幅提高。In a complex environment, titanium alloys should possess wear-resistance and corrosion resistance of acidic medium. The present paper studied the electrochemical properties and corrosion resistance of hydrogen-free carburized Ti alloy samples in HCl and H2SO4 solution by means of electrochemistry and eroding. The result shows that after hydrogen-free carburization, the corrosionresistance of the samples immersed in HCl and H2SO4 solution is significantly improved.
