Abstract: An improved design for a thermal spray gun includes an atomizer (70, 102), a combustion chamber (10, 104), an interconnector (30, 106), and a barrel (50, 108). Also included are methods for thermally spraying a substrate. One method for thermally spraying a substrate includes directing at least one fuel stream and at least one oxidant stream to a thermal spray gun with the improved design to form a thermal spray and directing the thermal spray against the surface to apply the coating.
