Abstract: A system to coat a substrate includes a deposition chamber maintained at sub-atmospheric pressure, one or more arrays containing two or more expanding thermal plasma sources associated with the deposition chamber, and at least one injector containing orifices for each array. The substrate is positioned in the deposition chamber and each expanding thermal plasma source produces a plasma jet with a central axis, while the injector injects vaporized reagents into the plasma to form a coating that is deposited on the substrate. The injector orifices are located within a specified distance from the expanding thermal plasma source to obtain generally a coating with generally uniform coating properties.

Abstract: The present invention provides a deposition process for plasma enhanced chemical vapor deposition of a coating on a substrate. The process comprises detennining a target process condition within a chamber of an expanding thermal plasma generator; the generator comprising a cathode, a replaceable cascade plate and an anode comprising a concentric orifice; and thereafter replacing the cascade plate with another plate having a configured orifice to effect the identified target process condition. The plasma is then generated at the target process condition by providing a plasma gas to the plasma generator and ionizing the plasma gas in an arc between cathode and anode within the generator and expanding the gas as a plasma onto a substrate in a deposition chamber.
