Chrome plating over other bases than nickel





April 11, 2012

Q. Presently, we are doing chrome plating over nickel plated steel parts. Is it possible to coat chrome over anyother substances like zinc, copper,etc., other than nickel?

Thanks

A. Hi, Selvraraj.

Chrome can be plated over nearly anything, but you will not get a decorative nickel-chrome plating look, nor will you get nickel-chrome corrosion resistance, without the nickel. Please explain your situation for a more interesting and useful discussion. Thanks.

A. Hi,

Chrome plating on brass used by Mercedes Benz in the beginning and the chrome is shining, of course they polish the chrome after chrome plating operation.

Your question, Yes chrome can be applied on almost all materials without nickel.

A. Hi Ted,
Thanks a lot !

We are developing a decorative part which has to have equivalent finish of Nickel+Chrome. The base part is steel. We planned to reduce the coating cost, by eliminating the use of Nickel. Hence this question was posted. Corrosion resistance would be ~50 hours in NSS. Finish: similar or closer to NiCr. Do you have any suggestions for this?

Thanking you once again!

A. Hi,Selvaraj.

Well, no lower cost finish will come close to matching nickel-chrome in appearance, but you could perhaps do chrome-look paint.
