A method for producing a thermal spray powder includes: a preparing step of preparing a powder mixture containing a first particle made from zirconia-based ceramic containing a first additive agent and a second particle made from zirconia-based ceramic containing a second additive agent, the powder mixture having a 10% cumulative particle diameter of more than 0 m and not more than 10 m; and a secondary-particle producing step of producing a plurality of secondary particles each of which includes the first particle and the second particle sintered with each other.

A cold spray apparatus for applying a coating of particles to a substrate includes a nozzle assembly having a plurality of inner passages terminating at a common exit. The nozzle assembly includes a particle supply members in communication with the inner passages. The particle supply members supply the particles to flow and accelerate through the inner passages and out of the nozzle assembly via the common exit toward the substrate to be coated thereon. Furthermore, each inner passage includes a laser that emits a laser beam that is transmitted through the inner passage. The laser heats at least one of the particles and the substrate to promote coating of the substrate with the particles.

A powder convergence improves without varying the flow velocity and powder density of a powder flow. A processing nozzle includes an inner cone including a beam path that passes light from a light source, an outer cone arranged outside the inner cone, a fluid ejection channel formed by a gap between the inner cone and the outer cone, and including an ejection port that opens toward a process surface, and a fluid guide channel having a flow inlet for a fluid. The fluid guide channel guides the fluid toward the fluid ejection channel in a direction away from the beam path.

Described herein is an apparatus for applying and curing a light-curable material on a work surface. The apparatus includes a nozzle from which the light-curable material is applied to the work surface to form a layer of light-curable material on the work surface. The layer of light-curable material has a leading edge and a trailing edge defined according to a direction of movement of the nozzle relative to the work surface. The apparatus also includes a light source fixed relative to the nozzle. The light source is operable to direct a light beam to the trailing edge of the layer of light-curable material.

A coat forming apparatus 100 includes a droplet supply unit 110 and an active species supply unit 120. The droplet supply unit 110 is adapted to spray or drop a droplet for coat forming toward an object 116. The active species supply unit 120 is adapted to supply an active species to be brought into contact with the droplet moving from the droplet supply unit 110 toward the object 116. The coating is formed on a surface of the object 116 by the droplet that has been brought into contact with the active species.

A laser cladding device for applying a coating to a part comprising a laser which can generate laser light, which is adapted to heat the coating and the part, a main body defining a laser light channel adapted to transmit the laser light to the part, a coating channel adapted to transmit the coating to the part, and a vacuum channel and a nozzle having an exit. The nozzle comprises a delivery port at one end of the laser light channel, a coating port at one end of the coating channel, and a vacuum port at one end of the vacuum channel, wherein the vacuum port is positioned generally adjacent the delivery port In operation the vacuum port draws a vacuum, pulling the coating towards the part.

A branch location is arranged close to a nozzle, and the channel lengths are the same. A processing nozzle that includes a beam path for passing light from a light source and ejects a fluid containing a processing material from an ejection port includes a supply pipe that is arranged outside the beam path through which the light passes, and supplies the fluid, and a first branch pipe and a second branch pipe that supply the fluid from the supply pipe to the ejection port, and have the same total length.
