ADDITIVES FOR ZN-NI ALLOY ELECTRODEPOSITION ELECTROLYTE, ZN-NI ALLOY ELECTRODEPOSITION ELECTROLYTE COMPRISING THE SAME AND METHOD FOR MANUFACTURING ZN-NI ALLOY ELECTRODEPOSITED STEEL SHEET USING THE SAME
ADDITIVES FOR ZN-NI ALLOY ELECTRODEPOSITION ELECTROLYTE, ZN-NI ALLOY ELECTRODEPOSITION ELECTROLYTE COMPRISING THE SAME AND METHOD FOR MANUFACTURING ZN-NI ALLOY ELECTRODEPOSITED STEEL SHEET USING THE SAME
PURPOSE: An additive composite for Zn-Ni alloy electrodeposition electrolyte, Zn-Ni alloy electrodeposition electrolyte comprising the same and a method for manufacturing Zn-Ni alloy electrodeposited steel sheet using the same are provided to improve surface roughness and minimize burning by uniformly forming a upsetting layer. CONSTITUTION: An additive composite for Zn-Ni alloy electrodeposition electrolyte comprises water and additives. The additive composite is 5~10 weight% of one or more inorganic acids selected from a group consisting of sulfuric acid, nitric acid, phosphoric acid, boric acid, and chromic acid. Carboxylic acid is aromatic carboxylic acid.
