ABSTRACT:
The invention relates to a method for the electrolytic coating of materials, in particular metallic materials, whereby a chromium alloy is deposited from an electrolyte, comprising at least chromic acid, sulphuric acid, an isopolyanion-forming metal, a short-chain aliphatic sulphonic acid, the salts and/or halo-derivatives thereof and fluorides. According to the invention, an alloy can be deposited, which can comprise a high proportion of isopolyanion-forming metal as a result of the combined addition of the short-chain aliphatic sulphonic acid with the fluorides and is nevertheless smooth and lustrous. In comparison with the alloy coatings known in the state of the art, in particular chrome/molybdenum alloys the above is a definite advantage. Furthermore, the presence of fluorides in particular leads to the above deposited coatings having a significantly higher hardness.
