Nanostructured Tungsten Rhenium Components for Propulsion Systems, Phase I

Completed

Description

Revolutionizing the space propulsion industry through innovative, relatively low-cost, manufacturing techniques is extremely needed. Specifically, advancements are needed for components in new high-powered electrical, beamed energy, and nuclear propulsion systems. Innovative processes for fabricating large, net shape, nanostructured tungsten-rhenium components are proposed. Innovative liquid precursors, tungstic acid and perrhenic acid, will be used in conjunction with powders. Vacuum Plasma Spray parameters will be developed to deposit nanostructured W-Re material. The techniques will then be used to fabricate samples for microstructural characterization and tensile testing. After optimization, non-eroding throats will be fabricated and hot fire tested at ATK/Thiokol at no cost to the Phase I effort. Tungsten is being used for its high melting temperature and chemical stability, and rhenium is used to improve ductility. The ability to fabricate nanostructured tungsten-rhenium components to net shape will revolutionize the ultra high temperature materials industry.

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.
