MOLD AND METHOD FOR MANUFACTURING THE SAME, AND METHOD FOR MANUFACTURING ARTICLE WHICH HAS MINUTE UNEVENNESS STRUCTURE IN SURFACE

摘要

PROBLEM TO BE SOLVED: To provide a method for manufacturing a mold which can form the oxidation films with few depth unevenness of a pore, even if the gap of the pore is ≥180 nm.;SOLUTION: A method for manufacturing the mold 18 in which the oxidation film 14 having the pore 12 on the surface of the aluminum base material 10 includes: (a) a process to form an oxidation film 14 by anodizing a surface of the aluminum base material 10; (b) a process to remove the oxidation film 14 after the process (a); (c) a process to form the oxidation film 14 by anodizing the aluminum base material 10 by the voltage of less than 90% of the highest voltage applied in the process (a) after the process (b); (d) a process to expand a pore diameter of a pore 12 of the oxidation film 14 after the process (c); (e) a process to repeat the process (c) and the process (d)alternately.;COPYRIGHT: (C)2012,JPO&INPIT
