Electroplating process for high-gloss zinc coatings on metal involves using aqueous acid electrolyte containing zinc salt and heterocyclic aromatic, especially N-alkyl-pyridine compound, as brightener |
摘要 |
Heterocyclic aromatic compounds with at least one alkylated nitrogen as the heteroatom (I) are used as brightening agents in a process for electroplating metal surfaces with zinc and/or zinc alloy from an aqueous acid electrolyte containing zinc salt(s) and brightener(s).
