A metal member—polyarylene sulfide resin member complex superior in airtightness between the metal member and the polyarylene sulfide (PAS) resin member and a production method therefor, in which the complex comprises a metal member and a PAS member combined together into a one-piece shaped article by injection molding and satisfies conditions 1) and 2) as described, and the PAS resin member contains a PAS resin and a modified ethylene copolymer.

Metal member-polyarylene sulfide resin member complex and production method therefor

A magnesium alloy part is inserted into a mold, a resin composition is injected and joined to the part, and a composite is obtained. A part having, formed thereon, a surface layer of a metal oxide, a metal carbonate, or a metal phosphate in use of a usual conversion treatment or a modification method thereof can be used for the magnesium alloy plate. The surface that has a larger amount of crystal-like objects of a nanolevel on the surface layer composed of the metal oxide, metal carbonate, or metal phosphate has a higher level of hardness, microscopic roughness, and good injection joining force, and these parameters can be controlled by a conversion treatment method. A resin composition, containing PBT or PPS as the main component, is used as the resin composition part.

Composite of metal and resin and method for manufacturing same

A composite of a metal part and a resin composition part that is improved so that the metal and resin are integrally joined to have strong bonding properties, and a method for manufacturing the composite.
