<p><P>PROBLEM TO BE SOLVED: To provide a method which is feasible in safe working circumstances and enables integrated formation of a metal material and a thermoplastic resin with sufficient bonding strength and manufacture of a metal/resin composite material at low costs. <P>SOLUTION: The method comprises injecting a thermoplastic resin onto the surface of a metal having a micro-porous hydroxy-containing film to integrate the metal with the thermoplastic resin via the film. The hydroxy-containing film can be formed easily at low cost by treating the surface of the metal with warm water. The film can also be considered as a hydroxylated and/or a hydrated film, or a film containing a hydroxide and/or hydrated oxide of the metal. Preferably, the micro-porous hydroxy-containing film is at least 5 nm thick, more preferably 5-100 nm thick, is formed on the surface of the metal. The warm water treatment preferably comprises immersing the metal in warm water at 50°C or higher for 30 sec or longer, more preferably in warm water at 60-90°C for 1-30 min. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
