Chromium electroplating industry facts for uni project




Hello, I am doing some research for a mini-project at uni on the chromium electroplating industry and I need some information on plating baths : what they are, what chemicals are used in them, how long the electroplating process actually takes, etc...I have not been able to find out these basic facts, although there is a lot of really technical stuff on the net. Any help anyone can offer will be greatly appreciated. Thank you.

The conventional bath: Chromic acid (CrO3) 28 oz./gal (U.S.), 0.28 opg sulphate ion (100:1 ratio)
110 degrees F, 100 Amperes/square foot cathode current density, lead anodes, three minutes plate over bright nickel for a few millionths of an inch of decorative plate.

Best wishes,

Hi, Bethany. You may also find our Chrome Plating FAQ helpful to give you a quick understanding of the different types and applications, and to clarify Tom's reference to nickel plating.
