Re: copperplating

Hello everybody
Have a nice day. I am having soft copper plating facility. My bath is sulphate bath. I want to convert it into hard copper bath is it possible?.
If not then what would be the chemistry of hard copper bath?
I want to do plating on Mild Steel surface for making rollers.
my e-mail is aarchy_ind@hotmail.com
thanks

Re: copperplating

It is not advised to plate acid copper over steel, since you will have a copper immersion plate that lacks adhesion. You can coat the steel with a cyanide copper strike bath, then plate the hard copper over this layer. The concentrations of the copper sulfate, sulfuric acid, and hardening additive should be determined by your chemical vendor.
