Abstract
A steel strip (1) is electrolytically coated with a metal layer at least partly of zinc in an electrochemical cell having an insoluble anode (4), wherein the strip acts as cathode. The electrolyte in the cell contains chloride ions and has high conductivity, reducing the voltage required. To avoid production of chlorine gas, hydrogen in the form of a hydrogen gas or gas containing hydrogen is supplied to the anode (4). The anode (4) is selected so that the anode reaction: H2 -> 2H<+> + 2e<-> (V> takes place, this reaction (V) predominating at the anode over the reaction: 2Cl<-> -> Cl2 &uarr& + 2e<-> (IV). <IMAGE>
