ABSTRACT:
A thermal spray apparatus is provided for thermal spraying a coating onto a substrate. The apparatus include a heating module for providing a stream of heated gas. The heating module is coupled to a forming module for controlling pressure and velocity characteristics of the stream of heated gas generated by the heating module. The thermal spray apparatus further includes a barrel capable of directing the stream of heated gas from the forming module. A powder injection module may be provided for introducing powder material into the stream of heated gas.
