Synergistic corrosion protection mechanism in Dy-modified EK3 alloys: Formation of anode phase and dense Dy-enriched corrosion product film

Key Points

• The formation of a dense Dy-enriched corrosion product film leads to enhanced corrosion protection mechanisms.
• Corrosion protection is maximized when an anode phase forms alongside the Dy-modified alloy structure.
• This observational analysis examines the synergistic effects of the Dy-enriched films and anode phase on corrosion resistance.
• Improved understanding of these mechanisms may enable better protective alloy designs for industrial applications.
