Abstract
A method of descaling titanium material including the steps of immersing titanium material having oxide scale on a surface thereof in a fused alkaline salt bath in accordance with needs; subjecting the titanium material to anodic electrolysis or alternate electrolysis in an electrolyte solution so as to dissolve the oxide scale; and subjecting the titanium material to acid pickling so as to remove remaining oxide scale or oxide film generated in the electrolysis.
