ELECTROLYTIC PRINTING ELECTRODE

摘要

An electrode (10) for electrolytic printing on a printing medium (14) comprises a metal substrate, preferably of Ti, which has a thin layer (18) of TiO2 between 200 ANGSTROM and 1,000 ANGSTROM deposited thereon and a tip layer (12) of RuO2 between 5,000 ANGSTROM and 10,000 ANGSTROM on the TiO2 layer. The RuO2 layer is at the extremity of the electrode which during the printing is in close proximity to the printing medium. This oxide layer provides an increase in wear resistance of about two orders of magnitude over non-oxidized electrodes.
