A coating is applied to a workpiece by ejecting a powdered material towards the workpiece using the energy of explosion in a recurrent cyclical operation. To produce an explosion, introduced into a combustion chamber of a detonation gun are a powdered coating material suspended in the stream of an inert gas and a gaseous explosive mixture formed by mixing a combustible gas and an oxidizing gas with or without an addition of an inert gas. During the coating process the explosive mixture is formed continuously, and cyclically filling the combustion chamber by portions of the explosive mixture is accomplished by feeding the inert gas to the pipe connecting the mixing chamber to the combustion chamber, which enables regular termination of the stream of explosive mixture and prevents the flame from spreading to the mixing chamber.
