Title (EN) SURFACE-COVERED CERMET MEMBER AND METHOD FOR MANUFACTURING SAME
(FR) ELÉMENT DE CERMET RECOUVERT EN SURFACE ET SON PROCÉDÉ DE FABRICATION
(JA) 表面被覆サーメット部材及びその製造方法
Abstract: front page image
(EN)Disclosed is a surface-covered cermet member that can improve oxidation resistance while maintaining high performance of a titanium-type sintered compact. The surface-covered cermet member comprises an oxidation-resistant film (12) provided on a cermet base material (11) formed of a sintered compact having a hard phase composed mainly of one or more titanium compounds selected from titanium carbide, titanium nitride, and titanium carbonitride.  In the surface-covered cermet member, the oxidation-resistant film (12) is formed of a composite oxide containing titanium.
(FR)La présente invention a pour objet un élément de cermet recouvert en surface qui peut améliorer la résistance à l’oxydation tout en conservant une grande performance d’une pièce frittée de type titane. L’élément de cermet recouvert en surface comprend un film résistant à l’oxydation (12) prévu sur un matériau de base de cermet (11) constitué d’une pièce frittée ayant une phase dure composée principalement d’un ou plusieurs composés du titane choisis parmi le carbure de titane, le nitrure de titane, et le carbonitrure de titane. Dans l’élément de cermet recouvert en surface, le film résistant à l’oxydation (12) est constitué d’un oxyde composite contenant du titane.
(JA)【課題】チタン系焼結体の優れた性能を維持しつつ、耐酸化性を向上できる表面被覆サーメット部材を提供する。 【解決手段】本発明は、炭化チタン、窒化チタンおよび炭窒化チタンのうち、少なくとも1種以上のチタン化合物を硬質相の主成分とする焼結体によって構成されたサーメット基材11に、耐酸化膜12が形成された表面被覆サーメット部材を対象とする。本発明の表面被覆サーメット部材においては、耐酸化膜12が、チタンを含む複合酸化物によって構成されている。
