titleOfInvention | Method for manufacturing chromium-free blackened electroplating steel sheet with excellent surface appearance |
abstract | Disclosed are a chromium-free blackened electroplated steel sheet excellent in surface appearance and a method of manufacturing the same. Method for producing a black electroplated steel sheet according to the present invention comprises the steps of (a) forming an electroplating layer comprising a Zn-Ni alloy on the base steel sheet; And (b) forming a blackening electroplating layer including Zn-Ni alloy but not containing chromium (Cr) on the electroplating layer, wherein step (b) comprises sodium nitrate (NaNO 3 ). Characterized in that the electrolyte is carried out by a cathodic plating method. |
