COMPOSITE MEMBER, AND MANUFACTURING METHOD OF COMPOSITE MEMBER
To provide a composite member excellent in durability in a severe environment such as a high temperature environment and a corrosive environment and capable of suppressing generation of cracks and peeling, and a manufacturing method of the composite member.SOLUTION: A composite member of the present invention has a molded body (1) having a melted solidification structure which is formed on the surface of a metal substrate (2) having a transition metal as the main component. The molded body (1) contains a ceramics phase of at least one of TiC, TiN, and Ti (C, N) of 15-75 mass% and a metal phase of 25-85 mass%. The metal phase is made of Ni alone or an alloy having Ni as the main component. A mixed layer (3) having a thickness of 250 μm or more and containing Ti in the tilting width direction is formed on the surface layer part of the metal substrate (2) contacting the molded body (1).SELECTED DRAWING: Figure 2
【課題】高温環境や腐食環境などの過酷環境下での耐久性に優れ、割れや剥離の発生を抑制することができる複合部材および複合部材の製造方法を提供する。【解決手段】本発明の複合部材は、溶融凝固組織を有する造形体（１）が、遷移金属を主成分とする金属基材（２）の表面に形成された複合部材であって、造形体（１）は、ＴｉＣ、ＴｉＮおよびＴｉ（Ｃ、Ｎ）のうちの少なくとも１種のセラミクス相を１５〜７５質量％と、金属相を２５〜８５質量％含み、金属相は、Ｎｉ単体またはＮｉを主成分とする合金よりなり、造形体（１）に接する金属基材（２）の表層部に、Ｔｉを深さ方向に傾斜して含む混合層（３）が、厚さ２５０μｍ以上形成されていることを特徴とする。【選択図】図２
