A thermal spray assembly (10) for transforming precursor material (60) into a layer of deposited material joined to a substrate body. A plasma torch produces a plasma jet from a plasma nozzle (28) and a feeder mechanism (30) guides the precursor material into the plasma jet in use and is capable of providing a feeder orifice when in an open condition. The feeder mechanism (30) is provided with a distribution chamber configured for guiding moving precursor material azimuthally around the plasma torch, a plurality of deflector structures (38) configured for deflecting the precursor material (60) from the distribution chamber and guiding it into a guide chamber configured for guiding the precursor material (60) to the plasma jet in use. |
