摘要:
Disclosed is a composite in which an aluminum-plated steel sheet and a resin are securely and integrally joined together, as well as a corrosion resistant steel sheet. Through chemical etching the aluminum-plated steel sheet is caused to have a surface configuration, in which three-dimensional protrusions having pebble-like shapes with a diameter of at least about 0.3 μm or having irregular shapes with a minor diameter of at least 0.3 μm and a major diameter of at least several microns are scattered over a plain-like part, where 30 to 50% of the surface area of the plain-like part is accounted for by a portion covered with shallow recesses having a diameter of 20 to 50 nm in a state of being distributed adjacent to each other. The surface of the three-dimensional protrusions is mainly ceramic containing silicon and the flat part is mainly a ceramic containing aluminum. The steel is heated and welded under pressure to a resin composition, injection joining is performed or adhesion joining with another adherend is performed with a resin-based adhesive. Coating with a corrosion resistant material can also be performed.
