Thermal stabilization of coating material vapor stream

摘要

A coating system includes a work piece, a coating delivery apparatus configured to apply a coating material to the work piece in a plasma-based vapor stream, and a first electron gun configured to direct a first electron beam at the plasma-based vapor stream for adding thermal energy to the coating material in the plasma-based vapor stream.

主权项

1. A coating system comprising:
a work piece; a coating delivery apparatus configured to apply a coating material to the work piece in a plasma-based vapor stream; a first electron gun configured to direct a first electron beam at the plasma-based vapor stream at a region of the plasma-based vapor stream that extends from a location downstream from the coating delivery apparatus where the coating material transitions to vapor phase to a location upstream from the work piece for adding thermal energy to the coating material in the plasma-based vapor stream, wherein the first electron gun is further configured to scan the first electron beam across at least a portion of the region of the plasma-based vapor stream; a susceptor positioned adjacent to the work piece; and a susceptor-directed electron gun configured to direct an electron beam at the susceptor such that the susceptor radiates heat toward the work piece.
