  • 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.
    Type: Grant
    Filed: June 6, 2001
    Date of Patent: April 6, 2004
    Assignees: Ceramic Coatings Technologies, Inc., Burckhardt America, Incorporated
