Abstract

Diamond slicing wheels which have become worn from extensive use may be rejuvenated by an electrochemical etching process. The diamond wheel with a nickel matrix serves as the anode, and a platinum electrode serves as the cathode. The electrolyte is an acid bath consisting of 100 milliliters of orthophosphoric acid, 25 milliliters of sulfuric acid, and 75 milliliters of water, having one drop of anionic TRITONT* X-100 surfactant.
