A new method for the preperation of the titanium impregnated iron and steel was studied by the present authors. In the process of this study, iron and steel sheets were subjected to the action of the mixed gases of titanium-tetrachloride and hydrogen at an elevated temperature. Experiments for determining the conditions of this treatment were carried out and the following results were obtained which seemed to be most suitable : reaction temperature ; 900〜1,100℃ reaction time ; 1〜3 hrs. gaseous mixture ; hydrogen saturated with TiCl_4 at room temperature gas velocity ; 200〜400cc/min. Various measurements on the properties of specimens prepared by this method, such as mechamical properties, corrosion resistance, weldability and gas evolution, were also carried out and it was found that a pure iron sheet treated by this process had an excellent properties as a material for anode in a vacuum tube.
