<p><P>PROBLEM TO BE SOLVED: To provide a composite of the aluminum alloy and resin with high water resistance. <P>SOLUTION: A super-minute asperity surface of 20-40 nm cycle is formed by immersing the aluminum alloy in the hydration hydrazine aqueous solution of a several % concentration adjusted to 45-65°C in one to a few minutes, then the hydrazine is adsorbed in the aluminum alloy surface by immersing the aluminum alloy in the hydration hydrazine aqueous solution of 0.05-1% concentration assumed to be 15-55°C for a few minutes, and washing it in clear water, and next, drying it with the low temperature at 50-70°C. This is inserted in the mold for the injection formation, PPS resin composition 53 is injected into the surface and is connected to the aluminum alloy. An aluminum hydroxide layer 54 is formed on the aluminum alloy surface, by immersing the obtained injection joining object in the ion exchange water of 98°C and further heating it for one hour at 170°C. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
