Use of a surface layer or covering layer provided with open hollow chambers by anodic oxidation for structuring a surface of a cast part and/or workpiece

摘要: Use of a surface layer (3) or covering (6) provided with open hollow chambers (4) by anodic oxidation for structuring cast part and/or workpiece is new. The shaped as the molding casting. Preferred Features: made from aluminum oxide, silicon dioxide, iron oxidized steel titanium dioxide. Structuring carried out in nanometer region. have an average uniform diameter 10-500, preferably 15-200, especially 20-100 nm.
