Cr plating on carburized surface??
Cr plating on carburized surface??
(OP)
Hi,
Can anybody tell me if we can chrome plate a carburized surface? I do not know to what depth the surface was carburized.
Thanks in advance!

Carburization is done in this case to have an extremely hard surface so the chrome plate can be thinner, not have to have thickness for effective hardness.
My shop key ring is 3/16" x 2" dia. hard chrome plated carburized 1060 CS.

After the guides had a little wear after one about year, as stated in the previous post a lot were made into key rings which required considerable bending to close the gap of the cut ring. Never had any to crack or break.
I'll see if I can get any information if there is any bakeout. We were aware of the problems with H2 as we always baked out 4340 or D2 steel that we had Cr plated.

Coka's original post did not indicate the substrate material or intended service.

Ni-Hard 1 is a Ni-Cr cast iron that is normally supplied in a very hard (500-600 BHN) and brittle condition. This material is typically used for severe abrasive service environments. I have seen Ni-Hard 1 castings that can be supplied at lower hardness (450 BHN), if specified.
Just curious as to the reason for the chrome plate on an already hard surface? Is it for added corrosion protection in service? I would think that if the Ni-Hard is supplied in the fully hardened condition, all you would need is to have a lubricant to reduce friction and wear from metal to metal contact.

Metengr is correct in his comments and pehaps a crazy though why not consider laser hardening the surface? if cost permits?

Will your client consider any other processes such as HVOF spray coating. There are a number of good coatings offered by companies such as Praxair which might perform better than chromium plating.
