  • Ceramic coating deposition
    Patent number: 8642140
    Abstract: A material is applied to a part. The part is placed in a deposition chamber and a first electric potential is applied to the part. Components are evaporated for forming the material. The evaporated components are ionized. The first electric potential is modulated so as to draw the ionized component to the part. The modulation comprises a plurality of first steps for PA-PVD. Each of the first steps comprises a series of pulses of negative potential. The modulation further comprises a plurality of second steps for PVD alternating with the first steps.
    Type: Grant
    Filed: March 9, 2011
    Date of Patent: February 4, 2014
    Assignee: United Technologies Corporation
    Inventors: Igor V. Belousov, Yuriy G. Kononenko, Anatoly Kuzmichev, Leonid Shaginyan, Michael J. Maloney, John F. Mullooly, Jr.
