Patent number: 10233533Abstract: 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.Type: GrantFiled: January 7, 2015Date of Patent: March 19, 2019Assignee: UNITED TECHNOLOGIES CORPORATIONInventors: Joseph A. DePalma, Mladen F. Trubelja, David A. Litton, Dmitri L. Novikov, Sergei F. Burlatsky

Patent number: 9970098Abstract: 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.Type: GrantFiled: December 3, 2014Date of Patent: May 15, 2018Assignee: UNITED TECHNOLOGIES CORPORATIONInventors: Russell A. Beers, Joseph A. DePalma
