The present disclosure relates to a cold spray metal process for imparting electromagnetic interference (EMI) resistance or lightning protection to the surface of a polymer, and a polymer with surface EMI resistance, or lightning protection, articles coated therefrom, and methods of reducing or eliminating electrochemical interactions between the metallic coating and components of the polymer.

Equipment for selectively depositing, by shockwave-induced spraying, at least one particle on a deposition surface of a receiver substrate. The equipment including at least one laser source that emits a laser beam, a substrate carrier to which the substrate is fastened, a shockwave-generating layer having a first surface oriented toward the laser beam and a second surface oriented toward the deposition surface of the substrate, an optical system for directing and focusing the laser beam toward a focal region of the first surface. The second surface including a plurality of cavities, each cavity housing at least one particle. The laser beam generates a plasma in the focal region on the first surface and a shockwave that propagates within the generating layer from the first surface to the second surface in order to spray at least one particle in the direction of the deposition surface of the substrate.

A method for controlling gas dynamic spraying includes providing a particle jet by using an accelerating nozzle, illuminating the particle jet with illuminating light pulses, capturing images of the particle jet illuminated with the illuminating light pulses, and determining one or more velocity values by analyzing the captured images,
wherein the images are captured by using an imaging unit which includes imaging optics to form an optical image of an object plane on an image sensor by focusing light, wherein an optical axis of the imaging unit is inclined with respect to a central axis of the nozzle, and wherein the image sensor is inclined with respect to the optical axis such that the object plane is substantially parallel with a direction of movement of particles of the particle jet.

A component for a turbine engine may be formed by spraying particulate with a nozzle toward a substrate. The particulate may be deposited to form one or more annular layers and a reinforcing structure. The component may be a closed loop annular component having a reinforcing structure of specific dimensions enabled by the methods described.

Methods are provided for a post-treatment process for use with coatings deposited via thermal spray and/or cold spray to modify the microstructures of the coatings and improve associated cohesion and adhesion properties. Such process includes performing ultrasonic consolidation of the spray coating as a post-treatment step after deposition of the spray coating onto a substrate. A system for spray deposition and ultrasonic consolidation is also provided.

The present invention provides an iron-aluminum-based plated steel sheet, and a manufacturing method therefor, the iron-aluminum-based plated steel sheet comprising a base steel sheet and a plated layer formed on the surface of the base steel sheet, wherein the alloy plated layer comprises: a diffusion layer comprising an Fe—Al-based intermetallic compound having a cubic structure; and an alloyed layer formed on the diffusion layer and composed of an alloy phase differing from that of the cubic structure, the thickness of the diffusion layer is 3-20 μm, and the thickness of the diffusion layer is greater than 50% of the total thickness of the plated layer.

An apparatus for producing a three-dimensional object by spray deposition including a powder conveyance line A arranged to channel a flow of spray material entrained in a carrier gas to a nozzle (a first flow). The apparatus also has a process line B arranged to channel a flow of gas to the nozzle (a second flow). The apparatus also has a spray nozzle. The apparatus is such that pressure and temperature parameters of the first flow are controlled in real time, but for the second flow these parameters are not controlled in real time. The two flows merge to cause spray material to be propelled from the nozzle to a substrate to create a three-dimensional object.
