Title:
コーティングされていない鋼ストリップをめっき層で電気めっきする方法
Document Type and Number:
Japanese Patent JP7066707
Kind Code:
B2
Abstract:
This invention relates to a method for electroplating an uncoated steel strip with a plating layer from a trivalent Cr-electrolyte, where the uncoated strip is subjected to a cleaning and pickling step prior to the plating process and then subsequently subjected to a plating process in a plating section comprising of a series of consecutive plating cells, wherein in a first stage of the plating process a current is applied to the strip entering the first plating cell which current is insufficient to deposit a plating layer from the trivalent Cr-electrolyte, but which is sufficient to provide cathodic protection of the strip in the electrolyte, and wherein in a second stage of the plating process a higher current is applied to the strip to deposit a plating layer comprising chromium metal, chromium carbide and chromium oxide from the trivalent Cr-electrolyte.
