  • Thermal barrier coating utilizing a dispersion strengthened metallic bond coat
    Patent number: 7166372
    Abstract: The present invention relates to an overlay coating which has improved strength properties. The overlay coating comprises a deposited layer of MCrAlY material containing discrete nitride particles therein. The nitride particles are present in a volume fraction in the range of 0.1% to 15.0% and have a particle size in the range of from 0.1 microns to 10.0 microns. The coating may also have oxide particles dispersed therein.
    Type: Grant

  • Apparatus for steering the arc in a cathodic arc coater
    Patent number: 6036828
    Abstract: An apparatus for applying material by cathodic arc vapor deposition to a substrate is provided which includes a vessel, apparatus for maintaining a vacuum in the vessel, a disk-shaped cathode, apparatus for selectively sustaining an arc of electrical energy between the cathode and an anode, and apparatus for steering the arc around the cathode. The arc of electrical energy extending between the cathode and the anode liberates a portion of the cathode which is subsequently deposited on the substrate located inside the vessel.

  • Cathodic arc vapor deposition apparatus
    Patent number: 5932078
    Abstract: An apparatus for applying material by cathodic arc deposition to a substrate is provided which includes a vessel, means for maintaining a vacuum in the vessel, a cathode, a contactor, means for selectively sustaining an arc of electrical energy between the cathode and an anode, and an actuator. The cathode and contactor are positioned inside the vessel, and the contactor is electrically connected to the means for selectively sustaining an arc of electrical energy. The actuator selectively actuates the contactor into electrical contact with the cathode, and thereby electrically connects the cathode to the means for sustaining an arc of electrical energy.
