Abstract

Disclosed is a dual nozzle cap for thermal spray coating to which both a thermal spray coating method and a kinetic spray coating method are applied. The dual nozzle cap includes a nozzle unit including inner and outer nozzles, a gun insertion hole, into which the front end of a spray gun is inserted, and a gas connection hole, into which a gas connector to supply the gas is inserted, formed through one surface of the nozzle unit. In a space between the inner and outer nozzles, a gas collection part to uniformly distribute the high-pressure subsidiary gas injected through the connection hole, a neck part to apply pressure to the high-pressure subsidiary gas to accelerate the subsidiary gas, and a gas spray hole to spray the subsidiary gas supplied from the neck part together with a material sprayed from the spray gun are sequentially formed.

Description

technical field [0001] The present invention relates to a dual nozzle cap (Dual Nozzle Cap) for thermal spraying, and more particularly to one that is attached to the outer periphery of the flame injection port of the spray gun, so that the thermal spray flame and the additional injected auxiliary gas are sprayed together to adjust the thermal spray A device for the speed, temperature and purity of the flame. Background technique [0002] As we all know, Thermal Spray includes Thermal Spray Coating and Kinetic Spray Coating. The thermal spraying method is to spray the wire or metal powder as the coating agent after melting at high temperature. The power spraying method is to spray the coating powder onto the surface of the substrate to be coated at high pressure and high speed, and use the impact energy generated during the impact to melt the powder for coating. The above-mentioned thermal spraying methods are divided into gas type and electric type according to the type of...
