摘要

商用純鈦在硫酸水溶液中電解滲氫後表面氫化物之結構受電流密度、滲氫時間及添加劑所影響，其中影響效果最明顯者為添加劑。不添加硫代尿素（thiourea）時鈦之吸氫量及滲入深度隨電流密度及滲氫時間之增加而增加，其形成之氫化物格子參數亦隨電流密度及滲氫時間之增加而略增；若在硫酸水溶液中添加硫代尿素，則出現明顯抑制滲氫之效應，此效應在低電流密度、長時間滲氫下尤其明顯。

Structures of surface hydrides formed on commercial purity titanium having been electrolytical hydrogenated in aqueous sulfuric solution are affected by the aplied current density, the operating period and the additive. Among these, the most effective is the additive. Without adding thiourea, the intake of hydrogen and depth of diffusion increase with the applied current density and the operating period while the lattice parameters of hydrides also increase slightly under these conditions. The addition of thiourea in the solutiongives an inhibitive effect of hydrogenation which is prominent at lower current densities for longer operating periods.
