摘要: The purpose of the present invention is to provide a method for surface nitriding a titanium material as a convenient method for forming a hardened and nitrided layer having excellent wear resistance on the surface of a titanium material in a short period of time. In order to achieve this purpose, the present invention adopts a method for surface nitriding a titanium material characterized by blowing a nitrogen gas at a flow rate of at least 10 L/minute on the surface of a titanium material while heating the titanium material to 800°C-1000°C in an inert gas atmosphere to form a hardened and nitrided layer on the surface of the titanium ma - terial.
