| Abstract Scope |
The corrosion resistance of multi-principal element alloys (MPEAs) is intimately linked to the nature and stability of their passive films. This work explores the physical nature of passivity for a lightwieght MPEA using a suite of advanced surface-sensitive techniques, including atom probe tomography (APT), online atomic emission spectroelectrochemistry (AESEC), and X-ray photoelectron spectroscopy (XPS), and surface sensitive spectroscopy. These complementary approaches unravel the nanoscale chemistry, structure, and features of the passive film. By correlating film composition with electrochemical behavior, an attempt is made to provide new insights into the mechanisms governing passivity in complex alloy systems, relevant to corrosion-resistant MPEAs for extreme environments. |
