COMPOSITE ARTICLE OF MAGNESIUM MATERIAL AND RESIN COMPONENT, AND METHOD FOR PRODUCING SAID COMPOSITE ARTICLE

摘要

[Problem] To be able to efficiently produce a resin component on a magnesium material. [Solution] A composite article (1) is produced by forming an anodic oxide film (3) on one surface (2A) of a magnesium material (2) as a consequence of immersing the magnesium material (2) into an electrolyte solution and applying a voltage, and by joining a resin component (4) to the magnesium material (2) by using the anodic oxide film (3). The electrolyte solution is formed by dissolving sodium dihydrogen phosphate and sodium hydroxide in pure water. The weight mixture ratio (R1) of sodium dihydrogen phosphate and sodium hydroxide is 1:2<=R1<2:1, and the voltage is between 20 and 50 V.
