High-performance applications demand components free from flaws. Bearings, gears, and other steel components manufactured with contaminated materials can lead to devastating outcomes. While most steelmaking applications find impurities still slip into the process, for aerospace applications, complete elimination of impurities is the goal. Contaminant-free steel.
Enter the researchers at NASA’s Glenn Research Center where a method has been devised for “creating ultra-pure steel alloys that are free from ceramic particle contamination” and “can be used to make bearings, gears, or any other machine components.”
Glenn’s innovative method starts with only elementally pure (at least 99.99% pure) ingredients and ceramic-free melting processes followed by ceramic-free atomization and powder metallurgy techniques. ~ NASA
