  • Metal-resin bonded member and method of manufacturing the same
    Patent number: 11633892
    Abstract: An object is to provide a metal-resin bonded member that is easy to manufacture and has high bonding strength. The metal-resin bonded member includes a metal body having an iron oxide layer on the surface and a resin body bonded to the metal body via the iron oxide layer. The iron oxide layer has a thickness of 50 nm to 10 ?m. The iron oxide layer comprises 60-40 at % Fe and 40-60 at % O at the outermost surface side. The iron oxide layer contains magnetite (Fe3O4). The iron oxide layer is formed by heating the surface of an iron-based substrate at 200-850° C. in an oxidation atmosphere. The resin body is composed of polyphenylene sulfide (PPS). The bonding of the metal body and the resin body via the iron oxide layer can be carried out by insert molding, thermal adhesion utilizing friction heating, etc.
