A method and device for laser cladding by independently heating the cladding material and the surface of the workpiece consist in formation of the series of parallel annular laser beams, possibly different wavelengths, with an adjustable distribution of laser radiation power across the annular beams. The annular beams are transformed into a series of conical beams which are separately focused along a single optical axis, along which the cladding material is fed. The device can be supplemented with a cylindrical mirror for the multipass laser radiation through the stream of cladding material with the possibility of the laser radiation return to the laser resonator.

A thermal coating method for applying a functional layer to a workpiece surface, particularly for applying a running surface coating to a cylinder running surface of a crankcase of an internal-combustion engine, includes the steps of: melting a coating material by use of a melting device, applying coating material droplets to the workpiece surface by use of a gas jet aimed at the workpiece surface, which gas jet blows coating material droplets from a melting location of the melting device onto the workpiece surface, and cooling or rapidly freezing the coating material droplets during their transport from the melting location to the workpiece surface.

A method for producing an armor plating for protected vehicles is described. The method employs the following steps: supplying a substrate made of a metal and/or a nonmetal and coating the substrate with the aid of a thermal spraying process. A device for producing an armor plating is also described herein.

Systems and methods disclosed herein relate to texturing a metal surface. A method for texturing a metal surface comprises disposing a first ceramic coating onto a first surface on the metal surface, applying a media to the first ceramic coating, disposing a second ceramic coating onto the media, and/or heat treating the metal surface for an end duration.

A method of making a light weight component is provided. The method including the steps of: forming a metallic foam core into a desired configuration; applying an external metallic shell to an exterior surface of the metallic foam core after it has been formed into the desired configuration; and attenuating the component to a desired frequency by forming a plurality of openings in the external metallic shell.

A method of fabricating a material having a high concentration of a carbide constituent. The method may comprise adding a carbide source to a biocompatible material in which a weight of the carbide source is at least approximately 10% of the total weight, heating the carbide source and the biocompatible material to a predetermined temperature to melt the biocompatible material and allow the carbide source to go into solution to form a molten homogeneous solution, and impinging the molten homogeneous solution with a high pressure fluid to form spray atomized powder having carbide particles. The size of a particle of carbide in the atomized powder may be approximately 900 nanometers or less. The biocompatible material may be cobalt chrome, the carbide source may be graphite, and the fluid may be a gas or a liquid.

A process of fabricating a shield, a process of preparing a component, and an erosion shield are disclosed. The process of fabricating the shield includes forming a near-net shape shield. The near-net shape shield includes a nickel-based layer and an erosion-resistant alloy layer. The nickel-based layer is configured to facilitate secure attachment of the near-net shaped to a component. The process of preparing the component includes securing a near-net shape shield to a substrate of a component.
