Engineers at NASA's Glenn Research Center have invented a new solid lubricant coating for high-temperature wear applications.
Called PS/PM400, the alloy performs in temperatures ranging from approximately -150°C to greater than 900°C.
It has been formulated to provide high density, smooth surface finish, and excellent dimensional stability with low complexity and expense in fabrication.
This alloy is a significant upgrade over not only traditional lubricants such as oil and grease, but also solid lubricants like graphite or other carbon-based composite materials.
For that reason, NASA’s Inventions and Contributions Board selected Glenn’s PS/PM400 as NASA's 2018 Government and Commercial Invention of the Year winner.
