The invention is directed to environmentally stable solid lubricant coatings with bilayer transition-metal dichalcogenide structures that are designed to resist the effects of oxidation during long term storage, or during short exposures under conditions that would oxidize similar films that do not have these bilayer structures. In addition to improving oxidation resistance, these bilayer structures also facilitate the more rapid establishment of a low, steady-state friction coefficient than is possible with similar films that do not have these bilayer structures.

Environmentally stable solid lubricant coating

Refractory-reinforced multiphase high entropy alloys (RHEAs) advantageously providing high strength and fracture toughness in an as-AM deposited condition and other conditions are described.

Ultra-high strength multphase high-entropy alloys

The present invention relates to methods of forming a film between two surfaces, in which the film includes diamond-like carbon. Also provided herein are uses of such films, such in sliding contacts and in metal coatings.

Diamond-like carbon films and uses thereof

The present invention relates to metal coatings and methods thereof. In certain embodiments, the invention relates to ultra-low wear noble metal alloys, such as for use in electrical contact coatings.

Stable nanocrystalline metal alloy coatings with ultra-low wear

A nanosolder comprises a first metal nanoparticle core coated with a second metal shell, wherein the first metal has a higher surface energy and smaller atomic size than the second metal. For example, a bimetallic nanosolder can comprise a protective Ag shell 'glued' around a reactive Cu nanoparticle. As an example, a 3-D epitaxial Cu-core and Ag-shell structure was generated from a mixture of copper and silver nanoparticles in toluene at temperatures as low as 150&#xb0; C.
