Furthermore, the protective effect of Al<sub>2</sub>O<sub>3</sub> coating on galvanic corrosion of 921A/Ti80 couple under various factors was innovatively discussed.

However, the uneven distribution of the various phase compositions often leads to localized corrosion. In this work, the AlCoCr<sub>1+</sub><em><sub>x</sub></em>Fe<sub>1-</sub><em><sub>x</sub></em>Ni<sub>2.1</sub> (<em>x</em> = 0.6, 0.8, and 2.0) HEAs are designed using the calculation of phase diagrams (CALPHAD) method and prepared by vacuum arc melting. The results indicate that the AlCoCr<sub>1+</sub><em><sub>x</sub></em>Fe<sub>1-</sub><em><sub>x</sub></em>Ni<sub>2.1</sub> (<em>x</em> = 0.6, 0.8, and 2.0) HEAs are composed of three phases: face-centered cubic (FCC), body-centered cubic (BCC), and ordered body-centered cubic (B2) phases. BCC phase contains a high concentration of Cr, while B2 phase has a high concentration of Ni and Al. On the other hand, FCC is rich in Cr, Fe, and Co. By increasing the Cr/Fe ratio, the volume fraction of the FCC/B2 lamellar eutectic microstructure decreases, while the volume fraction of the BCC/B2 coherent network microstructure increases. This results in an increase in the corrosion resistance of the HEAs, evidenced by the low values of corrosion current densities and high corrosion potentials. The protective passive film’s formation depends on the Cr and Al content. The Cr-rich coherent nanophases in the Al-rich B2 phase result in a more homogeneous and thicker passive film, which can inhibit the expansion of corrosion pits. And advanced wear resistance counted on appropriate phase fraction, that is, FCC accounted for about 33.56 vol. % and BCC/B2 accounted for 66.44 vol. %. The wear rate of all the HEAs is ∼10<sup>–5</sup> mm<sup>3</sup>/(N·m), and the oxidation wear and abrasive wear play a dominant role in all the samples.

A 10-min conversion treatment was particularly effective compared with the effect on as-polished and 1-min treated specimens. After the conversion treatment, the surface films on the Al-matrix and Al<sub>6</sub>(Fe, Mn) particles became thicker and Mo-enriched.
