| Abstract Scope |
Friction and wear contribute to a significant amount of the world’s energy waste and machine part failures, making it a priority for countries to control these two factors. High entropy alloys are strong candidates for tribological applications because of their wide variety of excellent properties. Efforts in material design and surface treatments have been investigated to reduce wear, especially in extreme environments. With each new treatment, alloy, and environment, wear behaviors change drastically. Identifying and understanding the underlying wear mechanisms is crucial to the advancement of high entropy alloys for tribological applications. This work investigated the tribological properties and specific wear mechanisms experienced by a single-phase FCC 1.1 at% C-doped Fe40.4Ni11.3Mn34.8Al7.5Cr6 and a two-phase Fe28.2Ni18.8Mn32.9Al14.1Cr6 under both cryogenic temperatures and room temperature. The latter alloy was also exposed to a surface nitriding treatment to identify its potential to improve wear resistance. |
