Dendritic zinc growth on the edges of flat steel strip during electro galvanizing

Dendritic growth on strip edges during continuous zinc electroplating of flat steel strip for the automotive industry is a wellknown problem. They produce surface defects during the stamping process. In this work the effect of the electrolytic process variables on dendrites formation is studied. Zin...
