Abstract: A nozzle for a thermal spray gun and a method of thermal spraying are disclosed. The nozzle has a combustion chamber within which fuel is burned to produce a stream of combustion gases. The stream of heated gases exits through an annular exhaust which is located around an aerospike. The stream converges outside the nozzle and powdered coating material is introduced into the converging stream immediately downstream of the aerospike. The coating material is heated and accelerated before impacting on a substrate to be coated.

Abstract: The method for flame spraying thermoplastic powders provides to heat the article to be coated at a suitable working temperature and to feed the said thermoplastic powders, transported by an inert gas, a flow of compressed air and a flow of liquefied petroleum gas through respective separated discharge chambers (7, 9, 12), shaped inside a mixing device (1) of a spray gun. The thermoplastic powders are then projected, in a resulting flow (30), on the heated surface of the article to be coated, to determine the melting of the same powders at their contact with said heated surface. At least one couple of flows (31, 32) of compressed air is sprayed converging towards the resulting flow (30) flowing out of the mixing device (1), giving the resulting flow (30) a substantially flattened fan shape.

Abstract: Disclosed is a surface treatment device with a robust nozzle configuration. The device includes a nozzle for ejecting a primary stream of combustible substance to a gaseous atmosphere in an ejection direction; an ignition unit configured to ignite the primary stream in a point of ignition; and an impermeable shield providing a planar surface that is substantially opposite to the ejection direction and has in front of the nozzle a hole that allows passage of the primary stream. The shield is positioned between the nozzle and the point of ignition of the primary stream. The shield is advantageously dimensioned to allow simultaneous passage of the primary stream ejected from the nozzle and a circumferential secondary stream of gas from the gaseous atmosphere via the hole.

Abstract: The present invention provides a method and an apparatus for forming, by spraying, a commonly known amorphous coating film, which is not limited to a metallic glass or the like. According to this invention, a flame containing metal particles is ejected toward a base material from a nozzle, such that the material particles are melted with the flame. Thereafter, the melted material particles and flame are cooled before they reach the base material. For this cooling process, a gas is externally ejected toward the flame, such that the gas can gradually approach the central line of the flame. Preferably, the particle size of the material particles in the flame is within a range of 10 to 100 μm.
