There is limited understanding of surface degradation mechanisms in high entropy alloys (HEAs) in terms of their corrosion, erosion, and wear behavior. There are few reports and limited understanding of the response of these alloys in different environments and as a function of temperature. We report on the corrosion and wear mechanisms for several single-phase and complex multi-principal high entropy alloys. Potentiodynamic polarization and electrochemical impedance spectroscopy measurements were performed to understand the corrosion mechanisms. Wear behavior was evaluated for several HEAs as a function of temperature. The severity of corrosion and wear behavior changed with the test conditions. Raman and auger spectroscopy were employed to identify the surface degradation products and passivation layers. The good surface degradation resistance of HEAs makes them attractive for several structural applications in marine as well as elevated temperature environments.
