Abstract:
PROBLEM TO BE SOLVED: To provide a thermal spray system for proper coating upon thermal spray coating.SOLUTION: A thermal spray system 100 can include: a thermal spray torch 110 configured to produce an emission of a material; at least one camera 121, 123 configured to capture an image of the emission of the material emitted by the thermal spray torch; a diagnostic device 125 communicatively coupled to the at least one camera; and a controller 113 communicatively coupled to the diagnostic device. The camera 121, 123 may be configured to transmit an image of the emission of the material to a diagnostic device 125 that may be configured to determine a characteristic of the emission of the material based on the image. The diagnostic device 125 may transmit the characteristic to the controller 113 that may control a position of the thermal spray torch 110 based on the characteristic.

PROBLEM TO BE SOLVED: To prevent the generation of ignition due to the friction of a raw material powder with a discharge duct.SOLUTION: The thermal spraying apparatus provided with: a storage means 20 storing the raw material powder 10 and having a put-out port 21 for putting out the raw material powder; an ejector 30 sucking the raw material powder 10 from the put-out port 21 with the flow of a pressurized carrier gas and mixing the carrier gas with the raw material powder to make a mixture; and a spraying means 40 for spraying the mixture generated in the ejector 30; wherein in the thermal spraying appratus in which a refractory composition is formed by spraying and burning the mixture, at least a part of an inner surface forming a flow path of the discharge duct 33 of the ejector 30 is made from a resin or rubber.
Abstract:
An improved thermal spray apparatus (100) and method of promotes mixing of axially fed particles in a earner stream with a heated effluent stream without introducing significant turbulence into either the effluent or carrier streams. An axial injection port (114) includes a plurality of chevrons (120) at the distal end of the port. The chevrons (120) are located radially around the circumference of the distal end of the axial injection port to increase the shared area between the two flow streams at the outlet of the port.
