Abstract
A powder supply device for use in the formation of a coating by a laser beam treatment has its delivery pipe from the powder and carrier gas dispensing apparatus fitted with an expansion chamber into which the powder and gas enter via an inlet pipe carrying a powder diffuser. The expansion chamber has a conical part leading into an outlet pipe for carrying powder and gas to a discharge nozzle at a reduced rate determined by the rate of escape of gas from the expansion chamber via an exhaust pipe fitted with a flow regulator.
