First Claim
Patent Images
1. A method of coating a first surface area of an object, comprising:
- forming a plasma in a first cavity by subjecting a gas to an amount of electromagnetic radiation in the presence of a plasma catalyst;
adding at least one coating material to the plasma; and
allowing the at least one material to deposit on the surface area of the object to form a coating.

Abstract
Methods and apparatus are provided for igniting, modulating, and sustaining plasma (615) for various coating processes. In one embodiment, the surface of an object can be coated (247) by forming plasma in a cavity (230) with walls (232) by subjecting a gas to an amount of electromagnetic radiation power via electrode (270) and a voltage supply (275) in the presence of a plasma catalyst (240) in mount (245) and adding at least one coating material to the plasma. The material is allowed to deposit on the surface of the object (250) on mount (260) to form a coating (247). Various plasma catalysts are also provided.

32. A material deposition system comprising:
-
a first vessel in which a first cavity is formed;
an electromagnetic radiation source configured to direct electromagnetic radiation into the first cavity during deposition;
a gas source coupled to the first cavity such that a gas can flow into the cavity during deposition; and
a plasma catalyst located at a position selected from a group consisting of (a) in the first cavity, (b) near the first cavity, and (c) a combination thereof. - View Dependent Claims (33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56)
