钛在海水中的阴极充氢行为

Research of Cathodic Charging Hydrogen Process of Ti in Seawater

摘要:

运用H型双面电解槽，采用双面电解充氢法对海水中自然表面钛片进行恒电流电解充氢，研究了钛在海水中的阴极充氢过程。用X-射线衍射法对充氢后碎裂钛片进行检测，同时探讨了试样厚度、充氢电流密度和阳极氧化电位对于氢渗过程的影响。结果表明，表面膜是氢渗过程的控制因素：试样厚度增加，氢氧化峰值电流和峰值电流出现时间增加：峰值电流随充氢电流密度和B面氧化电位升高而增大，而峰值电流出现时间随充氢电流密度和B面氧化电位升高而减小。

Abstract:

s:Electrolyzing charging method with H pattern double-side electro bath and X-ray diffraction are used to charge Titanium samples and to research cathodic charging hydrogen process of Ti in seawater. At the same time, the effects of thickness of Ti samples, cathodic charging current density and anodic potential on the H permeation process are studied.The result indicates that the surface film of Ti is the main factor controlling the process of hydrogen permeation.Following the thickening of Ti samples voltic peak value and time for voltaic peak value are increased.With cathodic current density and potential of side B raising,voltaic peak value is increased,and time for voltaic peak value is reduced.
