Abstract:
A gas detonation apparatus utilizing energy from a detonation wave front (100) for applying powdered coatings to a workpiece (1), the gas detonation apparatus having a fuel and oxygen supply (16, 17), an ignition source (14), a combustion chamber (12), a means for supplying powder, and a barrel (13), the gas detonation apparatus further comprising:a transition portion (75) between the combustion chamber (12) and the barrel (13) located at the downstream end of the combustion chamber (13);the transition portion (75) having at least one bleed aperture (76) as a means for bleeding off energy (78) for the purpose of minimizing reflected energy (98) from interfering with the detonation wave front (100).
