  • Edge sharpener
    Publication number: 20040105959
    Abstract: An edge sharpening device has a metal body and at least one honing surface coated with ceramic created in an electrolytic bath. Profiles of the device can be triangular, planar, or V-shaped as well as curved. The ceramic can be deposited by passing a modified shaped wave alternating current through the incipient sharpening device in the presence of a passivating agent and an electrolytic agent.

  • Spinning rotor
    Patent number: 6716333
    Abstract: A hard, wear-resistant ceramic surface is applied to spinning rotor cups in an electrolytic bath on which is imposed a shaped-wave electric current. A special electrode has been designed to facilitate application of the coating to the unique shape of a spinning rotor cup under the shaped wave conditions.

  • Ceramic coated liquid transfer rolls and methods of making them
    Patent number: 6290834
    Abstract: Liquid transfer rolls such as printing rolls are made by imposing a hard ceramic coating on an incipient liquid transfer roll in an electrolytic bath subjected to a modified shaped wave alternating current, which causes dielectric breakdown and the formation of a hard ceramic coating on the roll. The roll is laser engraved to form liquid carrying reservoirs or cells on the surface of the roll, either before or after the ceramic coating is built on the roll.
