Title:
PRODUCTION METHOD FOR ALUMINIUM CASTING-ALLOY MEMBER FOR RESIN BONDING, AND ALUMINIUM CASTING-ALLOY MEMBER FOR RESIN BONDING OBTAINED USING SAID METHOD
Document Type and Number:
WIPO Patent Application WO/2014/170945
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide: a production method for an aluminium casting-alloy member for resin bonding, said method being capable of producing, with ease by way of a simple method, an aluminium casting-alloy member exhibiting excellent aluminium/resin bonding properties; and an aluminium casting-alloy member for resin bonding, said aluminium casting-alloy member being obtained using said method. Provided is a production method for an aluminium casting-alloy member for resin bonding, said method wherein die casting is used to prepare an aluminium casting-alloy substrate including 0.9-18 mass% of Si and 1.0-10.0 mass% of Mg, and the aluminium casting-alloy substrate is subsequently subjected to etching, under conditions in which the processing temperature is 30-80˚C and the processing time is 5-15 minutes, using an acidic etching solution comprising an aqueous solution of sulfuric acid and/or nitric acid, to dissolve Mg2Si crystallized products on a surface of the aluminium casting-alloy substrate and impart, upon the surface of the aluminium casting-alloy substrate, a fine uneven shape exhibiting excellent resin bonding properties. Also provided is an aluminium casting-alloy member for resin bonding, said aluminium casting-alloy member being obtained using this method.
