Abstract (en)

The method for metallic coating of a mold part, comprises mechanically and chemically cleaning the mold part by blast cleaning before the coating process and immersing the mold part into a melt of an aluminum-containing alloy for coating. After mechanical cleaning, the mold part is directly pretreated with an acid solution before coating process. The melt has a bath temperature of 650-800[deg] C. The immersion time is 2-6 minutes and the thickness of the coating is 50-500 mu m. The mold part before the coating process has a temperature between room temperature and 200[deg] C.

The mold part before the coating process has a temperature between room temperature and 200[deg] C and the mold part after the coating process has a temperature between 200[deg] C and the bath temperature. The mold part is subjected to a heat treatment in an oxidizing atmosphere after the coating process and then subjected to anodic oxidation. The mold part is colored after the anodic oxidation.
