Abstract
A pulsed detonation gun comprises a small-diameter detonation tube, an igniter, and an outlet for discharging detonation products containing a coating material. A detonable or reactive mixture containing a coating precursor is formed in the detonation tube, and the detonable or reactive mixture is ignited to produce detonation or reaction products containing the coating precursor or a coating material formed in situ during a detonation process or a deflagration process. The coating material is discharged through the outlet and is contacted with the substrate to produce a coating. The device is particularly useful for coating the inside surfaces of small-diameter tubes and a variety of other difficult-to-reach substrate surfaces.
