Patents by Inventor Gregor Baladjanian

Gregor Baladjanian 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).

  • High temperature braze repair of superalloys
    Patent number: 4285459
    Abstract: Cracks in superalloys are braze repaired after notching or cutting away material adjacent the cracks, filling the recess with a braze component containing a melting point depressant and subjecting the repair area to a first elevated temperature to form a melt. The melting point of the repair region is raised by diffusing the depressant into the braze material and repair region at second and third elevated temperatures lower than the first elevated temperature to form a repaired superalloy exhibiting highly desirable properties.
    Type: Grant
    Filed: July 31, 1979
    Date of Patent: August 25, 1981
    Assignee: Chromalloy American Corporation
    Inventors: Gregor Baladjanian, Robert L. Rothman
  • Rhodium-containing superalloy coatings and methods of making same
    Patent number: 3961910
    Abstract: Superalloy structures, such as high temperature components for jet engines and the like, are provided with aluminum-containing diffusion coatings enabling guantum extensions of service life through unique distributions therein of rhodium. The rhodium is prediffused into the alloy structure, and the resultant distribution minimizes aluminum migration into the structure and thus maximizes protective coating performance.
