ABSTRACT:
A method for preparing an integral cathode substrate and support includes the steps of placing formed metal parts on a pin holder, masking selected surface portions of the formed metal parts, etching the unmasked surface portions, and then removing the mask. The present method is an improvement over prior methods since the parts are arranged in a staggered array to increase the turbulence of the etchant during the etching step. The turbulence provides additional oxygen to increase the rate and uniformity of the etching.
