ANODIZED POROUS ALUMINA COMPOSITE MATERIAL AND ITS PRODUCING METHOD

摘要

PROBLEM TO BE SOLVED: To provide an anodized porous alumina composite material and its producing method with which in the case of filling up the other material into the anodized porous alumina fine holes with a vacuum deposition method, the filling structure having high aspect ratio can simply be obtained at a low cost. SOLUTION: This composite material is produced by filling up the other material into the fine holes of the anodized porous alumina. Then, this complex material is produced so as to fill up the other material into the fine holes with the vacuum deposition after expanding the diameters of the opening hole parts of at least fine holes with an etching treatment.
