Abstract
A thermal spray apparatus for depositing a coating on to a substrate is provided which includes a plasma generator for selectively changing gas from a gaseous state to a plasma, and apparatus for filtering plasma. Powder particles entrained in the plasma change from a solid state to a molten state. The apparatus for filtering the plasma permits only a high intensity region of the plasma to pass through to the substrate.
