Abstract: A nozzle for a thermal spray gun and a method of thermal spraying are disclosed. The nozzle has a combustion chamber within which fuel is burned to produce a stream of combustion gases. The stream of heated gases exits through an annular exhaust which is located around an aerospike. The stream converges outside the nozzle and powdered coating material is introduced into the converging stream immediately downstream of the aerospike. The coating material is heated and accelerated before impacting on a substrate to be coated.
