Abstract (en)
[origin: EP1205582A1] Process for decoratively coating metallic materials comprises depositing a chromium alloy from an electrolyte containing chromic acid, sulfuric acid, a metal forming isopolyanions and an organic compound. Independent claims are also included for: an electrolyte for carrying out the process; and a chromium-molybdenum alloy layer deposited by the process. Preferred Features: The metal forming isopolyanions is added to the electrolyte in the form of molybdic acid or molybdenum salts. The molybdic acid is added in an amount of 50-70 g/l. The organic compound is a short chain aliphatic sulfonic acid, its salts and/or halogen derivatives, especially methane sulfonic acid.
