Enabling Niobium-based Alloy and Coating Technologies (ENACT)

Active

Description

Design and benchmark novel oxygen-tolerant additively manufactured (AM) Nb-based alloys with advanced environmental barrier coatings (EBCs)

Benefits

Will enable more efficient propulsion/power conversion systems Addresses a critical space industry need for thrusters capable of higher temperatures, longer lifetimes, and improved reusability beyond legacy niobium (Nb) alloy C103 reaction control system (RCS) thrusters Enhanced reusability and reproducible improvements over SOA alloys/coatings is a key hurdle for adoption, and demonstration of representative thruster conditions >1400C can provide ~10% increase in specific impulse. Characterize legacy Nb-alloys C103 and Nb521 as benchmarks, then confirm the improved elevated-temperature mechanical and oxidation resistance of new oxygen-tolerant, lower-density Nb-base alloys (with/without oxide dispersion strengthening). Investigate the oxidation performance of alumina- and silica-forming EBCs for Nb-based alloys in comparison to heritage R512E(A) Si-Cr-Fe(Ti)-based slurry coatings.

Listed on TechPort itself — the most direct way to ask about this specific project.

How to get involved

This is a mature technology (TRL 7+) — the realistic path in is usually NASA's Technology Transfer Program: licensing an existing NASA patent, or a Space Act Agreement to use NASA facilities/expertise directly. NASA also runs a startup licensing program with no upfront fee for companies formed to commercialize a specific NASA technology.

None of these are guaranteed paths for this specific project — TechPort itself doesn't have an "apply" button. Reaching out to the contact(s) above with a specific question is usually the fastest way to find out what's actually open.
