refurbishment of hard chrome plating
 
refurbishment of hard chrome plating
i have been advised that, in order to refurbish a worn hard chrome plating on a component, i will have to completely remove the old plating and re-deposit a new one (i.e. onto base material). is there any reason why the existing cr surface cannot be activated and plated onto?
check out our whitepaper library.
hi,
i'm not quite sure of the reason you can't plate onto the old chrome - it probably just won't work. as far as i know you have to strip the old plating and re-plate.
ori
the old chrome layer, being brittle and probably containing small cracks, does not provide a secure substrate for re-plating, hence total removal.
