[Problem] A composite of a metal part and a resin composition part improved to firmly integrally join a metal and a resin, and a production technology thereof.n n n [Solution] A magnesium alloy component is inserted into a mold, a resin composition is injected and bonded to obtain a composite. The component which formed the surface layer of a metal oxide, a metal carbonate, or a metal phosphate can be used by using the chemical conversion treatment of the conventional method or its modification method for the magnesium alloy plate 1. The greater the amount of crystalline material at the nano level in the surface layer made of metal oxide, metal carbonate, or metal phosphate, the harder and microscopically visible surface is, and the injection bonding force is good, and they can be controlled by chemical treatment. have. One resin composition component uses the resin composition 4 which has PBT or a PPS main component.n n n n Metal parts, resin composition parts, composites, molds, injection |
