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

Several innovative technologies, including pressure-drop minimization, advanced refractory high entropy alloys, and advanced manufacturing can provide a compact heat exchanger that extends the state-of-the-art heat-exchanger operating range. The compact heat exchanger can reduce pressure drop losses by 100 to 500%, while retaining most of the heat transfer. The compact heat exchanger can be fabricated from refractory high entropy alloys that have favorable corrosion, thermal fatigue, and creep properties at high temperatures and pressures. Therefore, the compact heat exchanger using high entropy alloys can operate at &#x3e;800&#xb0; C. and 80 bars.

Refractory high entropy alloy compact heat exchanger

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

The present invention relates to an additively manufactured (AM), monolithic, multi-axis linear flexural cantilever test artifact. The artifact is monolithic in that is it one continuous part with no assembly. The artifact can be non-destructively evaluated and includes a support frame, cantilevers, and a mount.

Test artifact for non-destructive evaluation

The present invention relates to an in situ testing system, which includes a wear tester and an enclosure. The wear tester is configured to apply a normal load, by way of a tip, to a surface of the test sample. Use of an enclosure allows such wear testing to be conducted in a controlled environment.

In situ environmentally-isolated wear tester

The present invention relates to monolithic structures for use as an electrical contact. In particular, these structures are formed from a laminate alloy, which in turn is composed of a MAXcompound. Electrical contact assemblies and electrical components having such contacts are also described herein. In some example, such monolithic structures display increased wear resistance, which is useful for sliding electrical contacts.

Monolithic MAX phase ternary alloys for sliding electrical contacts

In one embodiment, a sliding contact system includes a first metal contact, a second metal contact in sliding engagement with the first contact, and a lubricant in which the first metal contact and the second metal contact are immersed to inhibit oxidation and cold welding of the contacts.

Long-life metal sliding contacts
