Seeking Technical Help for Hard Chrome

I have a small business, a licensed gun shop and I am very interested to know about electroplating especially HARD CHROME . We have chromed several guns already for our customers but we still have problems with our quality. I think it has something to do with the proper replacement of the used chemicals and the correct timing when to add or discharge some of its components. The main reason why I am sending you this e-mail is because I strongly believe that you can give me some professional advice regarding these problems. Also if you can give me informations about Black Chrome please include it in your reply, thank you very much. Hoping for your quick response.

Hi Mario. I have working with black chrome and study what can happen in the bath solution. If you can describe your problem more specific, maybe I can help you with the black chrome. Regard

Mario, I suggest that you check out the following link:

Although this article deals with chrome plating of models, I found that it gives many good pointers on hard chrome plating in general.

Decorative nickel chrome can be applied on the non-functional surfaces of the guns. Hard chrome or functional chrome is applied on the ID of the gun barrel. Both of these processes can be applied by quality plating shops. Remember anything is possible if you are willing to pay the price.
