摘 要: 研究了离子注入工艺与注入元素对工业纯钛在硫酸和氢氧化钠溶液中析氢活性的影响，测定了工业纯钛及其注入Ni+， W+， Mo+， C+， Nd+等离子后在硫酸溶液和氢氧化钠溶液中的阴极过程动力学参数。结果表明，如果选择适当的注入离子和注入工艺，可以大大提高工业纯钛的析氢活性。注入的离子对提高工业纯钛析氢活性的影响有W+>Mo+>Ni+>Nd+的规律，特别是W+和C+的重叠组合注入对提高析氢活性效果最为明显，在硫酸溶液中其Tafel关系中的常数 a 降低470 mV。

Abstract:The effects of ion implanted process and elements on the activity of hydrogen evolution of industry titanium were studied. The cathodic dynamic parameters of industry titanium implanted with Ni+，W+，Mo+，C+ and Nd+ in H2SO4 solution and in NaOH solution were obtained. The results show that the activity of hydrogen evolution of industry titanium could be improved greatly by suitable implanted ions and process. Especially，the overlap-implantation of W+ and C+ can greatly improve the catalytic activity of hydrogen evolution，and the constant a of Tafel equation decreases by 470 mV in H2SO4 solution. The order of catalysis hydrogen evolution is W+>Mo+>Ni+>Nd+.
