Abstract: The invention relates to a process for the electrolytic coating of metals with zinc or a zinc alloy in which matt surfaces are obtained, by deposition of zinc from an electrolyte solution comprising a zinc salt selected from zinc sulfate or an alkanesulfonate of zinc or mixtures thereof, and, if desired, further metal salts, an acid selected from sulfuric acid or an alkanesulfonic acid or a mixture of the two acids, and at least one additive for improving the surface roughness and preventing dendritic edge growth, selected from nitrogen-containing surface-active compounds, which may be ionic or nonionic, sulfur-containing anionic surface-active compounds, and surface-active compounds based on multifunctional alcohols having at least three hydroxyl groups. The invention furthermore relates to an electrolyte composition for electrolytic coating of metals with zinc or zinc alloys, and to the use of said additives for improving the surface roughness and preventing dendritic edge growth in the electrolytic coating of metals with zinc or a zinc alloy in an alkanesulfonic acid-containing electrolyte.

Abstract: The invention relates to a method for electrolytically coating metalswith zinc or a zinc alloy. Matt surfaces are obtained by depositing zinc from an electrolyte solution containing a zinc salt selected from zinc sulphate or an alkane sulphate of zinc or mixtures thereof and optionally other metal salts, an acid selected from sulphuric acid or an alkane sulphonic acid or a mixture of both acids and at least one additive for improving surface roughness and for avoiding dendritic edge growth, selected from surface active compounds containing nitrogen which can be ionic or non-ionic, anionic surface active compounds containing nitrogen, and surface active compounds derived from multi-fuctional alcohols with at least three hydroxy groups. The invention also relates to an electrolytic composition for an electrolytically coating of metals with zinc or zinc alloys, in addition to the use of the above-mentioned additives for improving surface roughness and avoiding dentritic edge growth when metals are electrolytically coated with zinc or a zinc alloy in an electrolyte containing alkane sulphonic acid.
