Compositionally complex alloys containing four or more principal elements provide an opportunity to explore a wide range of compositions, processing, and microstructural variables to find new materials with unique properties. In particular, the discovery of novel alloys that form self-healing, protective passivating films is of substantial interest. Probing experimentally a robust landscape of such alloys requires the utilization of high-throughput electrochemical methods to uncover key differences, ideally captured by discriminating metrics, indicative of superior properties. Herein, a methodology is demonstrated using a scanning droplet cell for a rapid passivation behavior evaluation of Al0.7-x-yCoxCryFe0.15Ni0.15 combinatorial alloy library in 0.1 mol l−1 H2SO4(aq).
