<p><P>PROBLEM TO BE SOLVED: To provide a method for manufacturing a metal member which has both of enhanced fatigue characteristics and corrosion resistance, and to provide a structural member. <P>SOLUTION: The method for manufacturing the metal member includes: a projection step of projecting particles with an average particle size of 200μm or smaller onto the surface of a metal material including an aluminum alloy with the use of compressed air/compressible gas; and a chemical conversion treatment step of forming a coating film on the surface of the metal member through chemical conversion treatment, after the projection step. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
