<p><P>PROBLEM TO BE SOLVED: To provide a method for improving the fatigue life of a metal member which is subjected to shot peening treatment using a simple process to prevent the deterioration of fatigue life due to the inclusion of corners and edges that may occur in the shot peening treatment. <P>SOLUTION: The metal member method for manufacturing includes a deburring process for removing burrs on the corners and edges of the metal member 10, and a blasting process in which particles with an average particle size of 10-400μm are blasted onto the surface of the metal member so that chamfering need not be applied after the deburring process. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
