Abstract
A surface treatment method for a metal composite body, comprising: providing a metal composite body, comprising a first metal part and a second metal part integrated into one body; roughening the exposed surface of the first metal part of the metal composite body by using an etching solution; anodizing the roughened metal composite body to form an oxide film on the surface of the second metal part; and etching the anodized first metal part of the metal composite body by electrochemical etching to form a plurality of micropores. The metal composite body is firstly corroded to roughen the surface of the first metal part, and then the metal composite body is anodized to form an aluminum oxide film on the surface of the second metal part of the metal composite body, and then electrochemical etching is performed to etch micropores of a desired size on the surface of the first metal part.
