Influence of diaminomaleodinitril on quality of galvanic nickel coverage was investi-gated. Structure and physical-chemical properties of nickel coverages were studied. It was established that diaminomaleodinitril introduced to standard electrolyte of nickel-plating (10 – 50 mg/l) is the effective brightener. The light-reflecting ability of the nickel-plating reaches of 82 %. The roughness of nickel coverage is reduced by a factor of 2.5. The electrolyte sca-ter ability is increased by a factor of 2.

Key words: electrochemical nickel-plating, electrolyte, brightener addition
