Matt zinc coating and method for the electrodeposition of matt zinc coatings

摘要

Zinc coatings with an average surface roughness (RMS) of 10-150 nm. Independent claims are included for (1) electrolytes for the deposition of matt zinc coatings on a substrate, containing delustering agent(s) as well as a source of zinc ions (2) a method for the deposition of matt zinc coatings by pre-treatment of the substrate surface followed by contact with the above electrolytes .
