Abstract
A system for depositing coating on a workpiece includes a deposition chamber within which is formed a vortex to at least partially surround a workpiece therein.
Claims13
A system for depositing coating on a workpiece comprising:
- a deposition chamber;
- an electron beam gun positioned within the deposition chamber so as to point toward an ingot, a gas temperature within said deposition chamber maintained by the electron beam gun at greater than 1300 degrees F. (704 C);
- and
- a manifold to inject process gases toward an upper wall of the deposition chamber to form a vortex within the deposition chamber around a vapor plume from the ingot.

A system for depositing coating on a workpiece comprising:
- a deposition chamber, at least one wall of the deposition chamber having a thermal barrier coating;
- an electron beam gun positioned within the deposition chamber so as to point toward an ingot;
- a manifold to inject process gases toward the upper wall of the deposition chamber to form a vortex within the deposition chamber around a vapor plume from the ingot;
- and
- a refractory plate in a vortex area of the deposition chamber.

A system for depositing coating on a workpiece comprising:
- a deposition chamber, at least one wall of the deposition chamber having a thermal barrier coating;
- and
- an electron beam gun positioned along a junction of an upper wall and a side wall of the deposition chamber so as to diagonally point toward an ingot, a gas temperature within said deposition chamber maintained by the electron beam gun at greater than 1300 degrees F. (704 C);
- and a manifold to inject process gases toward the upper wall of the deposition chamber to form a vortex within the deposition chamber around a vapor plume from the ingot.
