Corrosion Degradation Behaviors of Ti6Al4V Alloys in Simulated Marine Environments

Detailed tests and characterizations were used to investigate the corrosion degradation behaviors of Ti6Al4V alloys in simulated marine environments. These suffered from very slight pitting a miniscule weight loss 0.018 mg/cm2 during 50 cycle salt spray exposure but experienced significant oxygen erosion high-temperature oxidation test, resulting high gain 2.657 at 400 h. The reactions simultaneously occurred hot test. chlorine (Cl2) induced by eutectic reaction mixed salts accelerated substrate led higher 4.265 In contrast, this alloy severe damage salt–water vapor synergy TiO2, Al2O3, V2O5 was aggravated synergistic action water. forming hydrochloric acid (HCl) further degraded matrix metal consequently 16.358 current findings provide comprehensive understanding for mechanisms Ti these specific
