Chromium plating

摘要

The present invention relates to a plating bath for electroplating various metals with chromium, prepared from 100 g to 1600 g chromium trioxide per liter, 0.3 weight percent to 15 weight percent Cl (chlorine or chloride ions) calculated on the chromium trioxide, and/or 0.3 to 10 weight percent I (iodine and/or iodide ions) calculated on the chromium trioxide said plating bath optionally containing also from 0.3 weight percent to 2 weight percent sulfate ions calculated on the chromium trioxide, and to a process of electroplating of metals from such plating baths, which is effected at a temperature between room temperature and about 60 DEG C. at a current density from 10 A/dm2 to about 270 A/dm2.
