Black chromium plating process |
| abstract |
A process for producing a lustrous, deep black, corrosion resistant, adherent film upon a conductive base which comprises electrodepositing such film upon such base acting as a cathode, employing an electrolyte comprising: A. 20 - 35 percent by weight water; and B. 65 - 80 percent by weight of a mixture of: 1. 30 - 75 PERCENT BY WEIGHT CHROMIC ANHYDRIDE; AND 2. 25 - 70 PERCENT BY WEIGHT ACETIC ACID, WHILE MAINTAINING THE ELECTROLYTE AT A TEMPERATURE OF 60* TO 80* F. while passing a current therethrough at a current density of 125 to 1,000 amperes per square foot. |
