Oleg Vladimirovich Selifanov has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Abrasive material for precision surface treatment and a method for the manufacturing thereof
    Patent number: 5711773
    Abstract: An abrasive material is proposed which is useful for the precision treatment of surfaces. This material may be in the form of an abrasive layer adhered by chemical and/or physical bonds to a carrier, the latter preferably made of a flexible material such as plastic. Alternatively, the abrasive material may be in the form of a free abrasive without a carrier. The abrasive material may be in the form of a vacuum condensate consisting of at last 80 atomic percent of an ultradispersed composite superhard diamond-like substance, preferably containing carbon, and including not more than 0.1 atomic percent hydrogen and oxygen, combined. The abrasive material is preferably obtained from the pulse-flows of an accelerated electroerosive plasma.
    Type: Grant
    Filed: March 25, 1997
    Date of Patent: January 27, 1998
    Assignees: Plasmoteg Engineering Center, TEGO Scientific and Engineering Center of Physics and Technology of Thin Films
    Inventors: Oleg Vladimirovich Selifanov, Eduard Ivanovich Tochitsky, Valerii Vladmiriovich Akulich
