Oxidation and molten salt corrosion behavior of AlCoCrFeNi2.1Mo0.3 high-entropy coating manufactured by atmospheric plasma spraying

Key Points

• Oxidation and corrosion rates decrease significantly when using high-entropy coating, implying better protection against environmental factors.
• The high-entropy coating demonstrated a corrosion resistance up to 80% compared to traditional coatings in molten salt environments.
• Assessment using atmospheric plasma spraying revealed enhanced metallurgical properties in the high-entropy coating after testing.
• Findings underscore the potential for prolonged equipment lifespan in high-stress applications, highlighting durability against corrosion.
