Abstract:
1. An electron beam vapor deposition apparatus comprising: a coating chamber for depositing a coating on a work piece; a coating device including at least one crucible for presenting at least one source coating material, the coating device having a physical vapor deposition mode of depositing the at least one source coating material and a directed vapor deposition mode of depositing the at least one source coating material; wherein the at least one crucible includes a funnel-less physical vapor deposition crucible and a directed vapor deposition nozzle having a funnel for jetting a gas stream therefrom; at least one electron beam source for evaporating the at least one source coating material; and a controller configured to move a transport holding the work piece at a first speed in response to the physical vapor deposition mode and at a second, different speed in response to the directed vapor deposition mode.
