VERFAHREN ZUR ENTSCHICHTUNG EINER AUF EINEM HARTMETALL-WERKSTÜCK AUFGEBRACHTEN HARTSTOFFSCHICHT

摘要

A hard material layer deposited on a hard metal work piece is removed by electrolytic passivation in which a maximum current density equal to at least 0.01 A/cm<2> is generated on the work piece at the beginning of the layer removal process. In doing this, the hard material layer rapidly flakes off without causing substantial damage to the hard metal material located underneath.
