A gas cap for a thermal spray gun has a spray passage extending from the combustion chamber to an exit end, and a thermal spray material is fed into the passage. A nozzle component of the gas cap is formed of a tubular inner member in thermal contact with a metallic outer member, such as copper, that is in contact with a fluid coolant. The inner member is formed of a hard, thermally conductive material, preferably a carbide in a metal matrix, such as tungsten carbide in cobalt.
