HIGHLY CONCENTRATED SUPERSONIC LIQUIFIED MATERIAL FLAME SPRAY METHOD AND APPARATUS

摘要

HIGHLY CONCENTRATED SUPERSONIC LIQUIFIED MATERIAL FLAME SPRAY METHOD AND APPARATUS Within ultra high velocity flame spray apparatus, the oxy-fuel products of combustion under pressure exit from an internal burner and pass through a spray nozzle of extended length. Metal or ceramic material in thin diameter rod form or as particles are fed to the nozzle inlet at a point at or just ahead of the throat of the nozzle bore. The exceptionally long nozzle flow path and the mode of introduction of the material into the flame spray insures a concentrated and highly focussed more of spray material for material spray coating downstream of the nozzle at supersonic speed.
