A method for fabricating an electrical conductor on a substrate by cold spraying includes propelling a solid powder composition that includes copper and highly oriented pyrolytic graphite using a gas propellant, and directing the solid powder composition towards the substrate at a velocity sufficient to cause the solid powder composition to undergo plastic deformation and to adhere to the substrate to deposit the electrical conductor thereon.

In a first aspect, the present invention relates to a planar sputtering target comprising a target material layer built up by a layering of splats, wherein the target material layer has a layer width and has a microstructure which varies across the layer width. In a second aspect, the present invention relates to a method for manufacturing such a planar sputtering target.

The invention relates to a method of forming a 3-dimensional solid object, comprising the steps: a) cold spraying one or more metallic powder to form a solid three dimensional item; b) thermally sintering the item such that a portion of the sprayed powder liquefies and reduces spaces between, and/or non-adhesion of, one or more solid portions of the item; and c) causing or allowing the portion of the sprayed powder that liquefied on heating, to become solid.

Implementations are provided for fabricating a finished workpiece having a shaped portion. One implementation includes: a superplastic formation diffusion bonding (SPFDB) component; a cold spray additive manufacturing (CSAM) component; and a mold having a concavity. Various configurations can operate on a workpiece with the SPFDB and CSAM components in different orders. An implementation is configured to cold spray (with the CSAM component) an additive material onto the workpiece; and perform superplastic forming (with the SPFDB component) on the workpiece with the mold, thereby rendering the workpiece into the finished workpiece having the shaped portion. The shaped portion conforms to a shape defined by the concavity. Cold spraying results in an increased thickness of the finished workpiece in a target region, which can provide structural reinforcement, and which can have a tapered edge. The workpiece can be a metal substrate made of titanium, aluminum, stainless steel, or another material.

Provided is a nickel-based composite coating, method for producing the same and use thereof. A powder mixture is coated on the surface of a substrate to obtain a nickel-based composite coating, wherein the powder mixture comprises nickel-chromium-boron-silicon powders and barium titanate powders. The barium titanate powders are added to the nickel-based powders as a second phase to form BaTiO.sub.3—NiCrBSi metal-based ceramic composite coating. The nickel-based barium titanate composite coating has an excellent damping shock absorbing performance and gives the substrate strength as well. Comparing with the conventional coating materials, the coating obtained by the present disclosure through plasma cladding technique not only bonds with the substrate in a metallurgic way, but also has a small heat affected zone, specifically, an excellent damping shock absorbing performance. In embodiments of the present disclosure, vibration and noise generated by the cylinder head is reduced 20% by using the shock absorbing cladding coating.
