| Abstract: | The main components of additives and the performance characteristics of the first,second,and third generations of potassium chloride zinc plating were introduced.Low-foam carrier brightener is used in the third-generation potassium chloride zinc plating process.Besides having the advantages of the first-and second-generation processes,the third-generation has the following features:compressed air agitation is acceptable;large current density is allowed,hence production efficiency is improved;and the coating passivated with trivalent chromium has corrosion resistance in neutral salt spray test superior to that prepared by cyanide and alkaline non-cyanide zinc plating processes. |

| Keywords: | zinc plating potassium chloride brightening agent passivation corrosion resistance |
