  • Patent number: 10233533
    Abstract: A method for use in a coating process includes pre-heating a substrate in the presence of a coating material and shielding the substrate during the pre-heating from premature deposition of the coating material by establishing a gas screen between the substrate and the coating material. An apparatus for use in a coating process includes a chamber, a crucible that is configured to hold a coating material in the chamber, an energy source operable to heat the interior of the chamber, a coating envelope situated with respect to the crucible, and at least one gas manifold located near the coating envelope. The at least one gas manifold is configured to provide a gas screen between the coating envelope and the crucible. A second manifold provides gas during a later coating deposition to compress a vapor plume of the coating material and focus the plume on the substrate to increase deposition rate.

  • Publication number: 20190040525
    Abstract: An apparatus for use in a physical vapor deposition coating process includes a chamber, a crucible configured to hold a ceramic coating material in the chamber, an energy source operable to heat the interior of the chamber, a fixture for holding at least one substrate in the chamber, an actuator operable to rotate the fixture, and a controller configured to establish a plume of the ceramic coating material in the chamber to deposit the ceramic coating material from the plume onto the at least one substrate and form a ceramic coating thereon, and during the deposition, rotate the at least one substrate at a rotational speed selected with respect to deposition rate of the ceramic coating material onto the at least one substrate.

  • Patent number: 10145006
    Abstract: A method for use in a physical vapor deposition coating process includes depositing a ceramic coating material from a plume onto at least one substrate to form a ceramic coating thereon, and during the deposition, rotating the at least one substrate at rotational speed selected with respect to deposition rate of the ceramic coating material onto the at least one substrate.

  • Patent number: 9970098
    Abstract: A moveable evaporation source system may have an insulator disposed above a cathode support member, and a cathode support member disposed beneath the insulator and exerting an upward force on the insulator so that the upward force exerted by the cathode support member urges the insulator toward a down force source. A cathode may be placed between the insulator and the down force source and translated so that material liberated from the cathode may strike different portions of a workpiece as the cathode is translated.
