ADHESIVE-BONDED COMPOSITE CONTAINING METAL ALLOY, AND MANUFACTURING METHOD FOR THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a composite that is formed by combining a thermosetting resin molded product with a metal alloy shaped product by injection-bonding the thermosetting resin to metal alloys so as to have excellent corrosion resistance, weather resistance, and heat resistance.SOLUTION: A metal alloy piece 61 is subjected to NAT treatment as follows: (1) forming an uneven surface 72 where the roughness period is 1 to 10 m and the height difference is up to about half of the roughness period, (2) forming ultra-fine irregularities with a period of 10 to 500 nm, most desirably 50 to 100 nm, on the inner-wall surfaces of the concaves, and (3) covering the surface with a thin layer of a hard ceramic phase. The composite is formed by integrating a metal alloy shaped product with a thermosetting resin molded product via an adhesive layer, by applying a one-pack epoxy adhesive, a phenol resin adhesive, or an unsaturated polyester-resin-based adhesive to insert the metal alloy piece applied with the adhesive into an injection mold, and injecting a thermosetting resin composition having the same kind as the adhesive into the mold.
