Disclosed are interfacially modified particulate and polymer composite material for use in injection molding processes, such as metal injection molding and additive process such as 3D printing. The composite material is uniquely adapted for powder metallurgy processes. Improved products are provided under process conditions through surface modified powders that are produced by extrusion, injection molding, additive processes such as 3D printing, Press and Sinter, or rapid prototyping.

Nanothick flakes that are either flat and specularly-reflective in visible light or that have microroughness intentionally controlled to disperse or interfere with visible light. Coatings and inks utilizing such flakes. Method for fabrication of such flakes in partial vacuum includes the repeated multiple times deposition of a release layer over a substrate surface and a flake layer over the release layer to form a multilayer structure further reduced to individual flakes. Reactive metal is passivated inline with the deposition of the flake layer for superior corrosion resistance. Chemically-functional materials are optionally added to the release material to transfer their functionality to the surface of flake layer to create unique functional properties on a flake surface before the multilayer structure is removed from the substrate.

In a method for cold gas spraying a layer, coating particles are accelerated in a cold spraying nozzle. The particles have a plastic encapsulation. In said manner, the plastic is precipitated onto the substrate together with the metal material, thereby forming in particular layer compositions having good sliding properties, dirt repellent properties, or lubricating properties. The coating can be used as a bearing component of a sliding bearing, as a flow component, in particular as a rotor blade of wind power plants or body components of transportation vehicle, or as trim components of structures.

Highly dispersed, highly filled, low viscosity liquid compositions and uses thereof. A composition can include a carrier fluid, a plurality of nano- and micro-sized particles, and multiple dispersants. A carrier fluid can comprise nonpolar organic liquids. A plurality of particles can comprise inorganic particles. A portion of dispersants can exhibit different association affinities for nano-versus micro-sized particles. A composition can be free of water, other solvents, or diluents. A composition can comprise 30 weight % or greater of particles. A composition can exhibit a consistent viscosity of about 1000 centipoise or lower at about 25 C. A curable composition can comprise curable carrier fluids, such as, for example, monomers and/or oligomers. A composition can be utilized in chemical processing, microfluidics, colloidal fluids, 3D printing, coatings, and other types of additive manufacturing. An object can be made, for example, by vat polymerization 3D printing of one or more curable composition(s).
