Abstract
An apparatus for nickel electro-plating parts from nickel plating baths that use nickel sulfamate as a source of nickel has a tank containing the nickel plating bath and in which an anode and a cathode are immersed. A semi-permeable wall of sintered or polymer material separates a cathode compartment from an anode compartment.
Claims4
Nickel electro-plating apparatus comprising a tank receiving a nickel sulfamate-containing nickel plating bath, an anode and a cathode immersed in said bath, and a semi-permeable wall of chemically inert sintered material separating a cathode compartment from an anode compartment in said bath, wherein said semi-permeable wall of inert sintered material preventing oxygen-containing compounds from passing from the anode compartment to the cathode compartment.
Nickel electro-plating apparatus comprising a tank receiving a nickel sulfamate-containing nickel plating bath, an anode and a cathode immersed in sintered material or polymer separating a cathode compartment from an anode compartment in said bath, wherein said tank comprises two vertical vessels and a transverse channel communicating said two vessels and wherein the semi-permeable wall is placed in said channel.
