<p><P>PROBLEM TO BE SOLVED: To provide a method for forming an alumite film whose surface is excellent in smoothness, and to provide the alumite film. <P>SOLUTION: A first alumite film 1a is formed on the surface of an aluminum base material 2 by arranging the aluminum base material 2 in an electrolytic solution as an anode together with a cathode, and then performing a first energization between both electrodes. Thereafter, a second alumite film 1b is formed between the aluminum base material 2 and the first alumite film 1a by performing a second energization between both electrodes so that the amount of applied current becomes larger than that in the first energization. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
