Corrosion behavior and mechanism investigation of laser cladded Ti6Al4V coatings in hydrochloric acid corrosive media

Key Points

• Corrosion behavior of laser cladded Ti6Al4V coatings in hydrochloric acid is significantly influenced by coating properties.
• Experiments reveal that acid concentration affects the corrosion rate and mechanism at two distinct levels of influence.
• Assessment using electrochemical analysis identifies interfacial effects of hydrochloric acid on coating integrity and durability.
• Findings highlight the importance of material selection in corrosive environments for extended service life.
