Thermal-hardened chromium plating
--
We have a new bath for thermal-hardened chromium plating. The process allow us to have a bright coating of necessary thickness on a part of complicated form. A hardness of coating before heat treatment is equal 1100 Hv and after - 1500 Hv (400 degrees of Cent.,one hour).It is very important for us to understand, are there any effective industrial applications for such coatings. We are interested in different testings of this coatings and we are ready to send a samples of coatings to firms or persons who have interest to this deposits. I would be so grateful for any advice.

You could always prepare a sample of, perhaps, a hardened steel drill bit, with your coating, and just send them to companies who sell specialty coatings, along with a brochure containing information about the coating.

Sir,
A lot of platers would be interested in learning more about this product as it is unusual. Most chrome softens considerably when exposed to 400C and I have never heard of a 1500 Hv chrome or other plated product.
Have you published any articles that are available in the USA. If not, Metal finishing or AESF's surface finishing would certainly publish an article for you.
I for one, would be interested in its wear properties compared to regular chrome and/or electroless nickel. Unfortunately, I do not have test facilities.
