Patent number: 9133542Abstract: A coating apparatus comprises a coating chamber for coating the articles. The at least one preheat chamber is coupled to the coating chamber. The at least one loading station has a proximal end connectable to at least one of the preheat chambers when in an installed position at a distal end of the preheat chamber. The loading station further includes a carrier for carrying the articles and a drive system. The drive system is positioned to move the carrier between: a loading/unloading position of the carrier in the loading station; a preheat position of the carrier in the preheat chamber to which the loading station is connected; and a deposition position of the carrier in the coating chamber. A gas source is connected to the preheat chamber.Type: GrantFiled: November 30, 2010Date of Patent: September 15, 2015Assignee: United Technologies CorporationInventors: James W. Neal, Robert F. Latour, Benjamin J. Zimmerman

Publication number: 20130269611Abstract: A method and apparatus for applying a vapor deposition coating onto a substrate with a non line of sight or limited line of sight is disclosed. A vapor stream is provided in a chamber that is below atmospheric pressure. The vapor stream is impinged with a working gas that provides a flow that transports the vapor stream. The flow of the working gas is modified with a physical object that directs the flow to achieve a desired coating on the substrate.Type: ApplicationFiled: June 8, 2013Publication date: October 17, 2013Inventors: Michael D. Greenberg, Benjamin J. Zimmerman
