Preparation and characterization of cerium-based conversion coating on a Fe50Mn30Co10Cr10 dual-phase high-entropy alloy

Li-An Chen et al.

Summary: The mechanical properties of Fe50Mn30Co10Cr10 (at.%) dual-phase high-entropy alloy (DP-HEA) are superior to single-phase HEA, but its poor corrosion resistance due to high manganese content limits potential applications. This study successfully improved the corrosion resistance of Fe50Mn30Co10Cr10 DP-HEAs by applying a cerium conversion coating, particularly through continuous bath-heating processes. The thickness and CeO2 content of the coating formed by the T70 bath-heating process contributed to its superior anticorrosion properties.
