Abstract

In a process for casting a metallic semi-finished product into a casting, the semi-finished product is roughened on a surface which faces the casting, then being placed in a defined position in a casting mold and surrounded with casting metal, after which a firm bond is formed between the semi-finished product and the solidified casting metal at the roughened surface. The surface of the semi-finished product is roughened by high-pressure water blasting.
