Corrosion caused by salt-spray and fatigue failure resulting from cyclic sea wave and strong storm are common degradation problem in offshore structural steels, and their interaction would accelerate service failure of these steels. In this work, therefore, FeCoNiCrMn high-entropy alloy (HEA) coatings were first prepared on 321 steels to simultaneously improve their corrosion and fatigue resistance. Then the pre-corrosion in salt-spray environment and subsequent high-cycle fatigue (HCF) tests were conducted on both coated and uncoated steel. Th...
