  • Smooth diamond films as low friction, long wear surfaces
    Patent number: 5989511
    Abstract: An article and method of manufacture of a nanocrystalline diamond film. The nanocrystalline film is prepared by forming a carbonaceous vapor, providing an inert gas containing gas stream and combining the gas stream with the carbonaceous containing vapor. A plasma of the combined vapor and gas stream is formed in a chamber and fragmented carbon species are deposited onto a substrate to form the nanocrystalline diamond film having a root mean square flatness of about 50 nm deviation from flatness in the as deposited state.
    Type: Grant
    Filed: March 22, 1996
    Date of Patent: November 23, 1999
    Assignee: The University of Chicago
    Inventors: Dieter M. Gruen, Alan R. Krauss, Ali Erdemir, Cuma Bindal, Christopher D. Zuiker
  • Diamond film growth argon-carbon plasmas
    Patent number: 5849079
    Abstract: A method and system for manufacturing diamond film. The method involves forming a carbonaceous vapor, providing a gas stream of argon, hydrogen and hydrocarbon and combining the gas with the carbonaceous vapor, passing the combined carbonaceous vapor and gas carrier stream into a chamber, forming a plasma in the chamber causing fragmentation of the carbonaceous and deposition of a diamond film on a substrate.
