Abstract
A method is provided for flame-spraying powdered materials onto a substrate by means of an autogenous flame-spraying apparatus of the type in which a combustion gas-oxidation gas mixture is produced and ignited at the outlet of a burner nozzle with the powdered material conveyed by a carrier gas to the burner nozzle and introduced in the flame at the outlet of the burner nozzle. The working parameters of the flame-spraying apparatus are chosen so as to provide an energy constant P.sub.E which together with the kinetic energy E.sub.k of the particles enables the use of a broad range of flame speeds.
