Title (EN) ALLOY MEMBER AND METHOD FOR HARDENING SURFACE THEREOF
(FR) ÉLÉMENT D'ALLIAGE ET SON PROCÉDÉ DE DURCISSEMENT DE SURFACE
(JA) 合金部材およびその表面硬化方法
Abstract:
(EN) The present invention relates to a titanium or titanium alloy member and a method for hardening the surface of the titanium or titanium alloy member. The titanium or titanium alloy member is provided with a titanium or titanium alloy base material and a hardened layer which is formed on a surface of the base material as a result of oxygen diffusing to such surface. This method includes: a heating step of heating the titanium or titanium alloy base material of the member to a prescribed temperature in an inert gas atmosphere; a hardening step of introducing a mixed gas containing an inert gas and oxygen gas as a hardening treatment gas at a prescribed temperature and subjecting the surface of the base material to a hardening treatment; and a cooling step of cooling the base material to room temperature in an inert gas atmosphere.
(FR) La présente invention concerne un élément en titane ou en alliage de titane et un procédé de durcissement de la surface de l'élément en titane ou en alliage de titane. L'élément en titane ou en alliage de titane est pourvu d'un matériau de base en titane ou en alliage de titane et d'une couche durcie qui est formée sur une surface du matériau de base par diffusion d'oxygène vers ladite surface. Le procédé selon l'invention comprend : une étape de chauffage consistant à chauffer le matériau de base en titane ou en alliage de titane de l'élément à une température prescrite dans une atmosphère de gaz inerte ; une étape de durcissement consistant à introduire un gaz mixte contenant un gaz inerte et de l'oxygène gazeux en tant que gaz de traitement de durcissement à une température prescrite et à soumettre la surface du matériau de base à un traitement de durcissement ; et une étape de refroidissement consistant à refroidir le matériau de base à la température ambiante dans une atmosphère de gaz inerte.
(JA) 本発明は、チタンまたはチタン合金部材およびチタンまたはチタン合金部材の表面硬化方法に関するものである。チタンまたはチタン合金部材は、チタンまたはチタン合金の基材と、基材の表面に、酸素が前記表面へ拡散して形成された硬化層と、を備える。方法は、部材のチタンまたはチタン合金基材を、不活性ガスの雰囲気の下で所定の温度まで加熱する加熱工程と、所定の温度で、不活性ガスを含む混合ガスと、硬化処理ガスとしての酸素ガスとを導入し、基材の表面に対して硬化処理を行う硬化工程と、不活性ガスの雰囲気の下で基材を室温まで冷却する冷却工程とを含む。
