This study delved into the impact of applied load and sliding speed on the tribocorrosion characteristics in a 3.5% NaCl Solution of additively manufactured Ti6Al4V alloy (AM-TC4) for comparative analysis with the as-forged Ti6Al4V alloy (AF-TC4). Due to the unique thermal cycling process of additive manufacturing, AM-TC4 exhibits more beta phase and lattice distortion, resulting in a hardness increase of about 4 times. Moreover, AM-TC4 also displays higher OCP values than AF-TC4, indicating enhanced electrochemical stability and corrosion resistance. Hereby, AM-TC4 significantly improves the corrosive wear resistance with an obvious lower friction coefficient. Particularly, the corrosive wear rate of AF-TC4 is about 3.7 times that of AM-TC4 when sliding at 120 mm/min under 0.5 N. Variations in wear rates were notable at different loads and speeds, emphasizing the role of manufacturing processes in tribocorrosion performance. These findings highlight the advantages of additive manufacturing in enhancing the hardness, wear resistance, and corrosion performance of Ti6Al4V alloys, making them more suitable for demanding applications, including marine environments.
