Abstract
The TC4 titanium alloy is extensively utilized in marine engineering due to its exceptional comprehensive performance. However, when subjected to harsh marine environments, the TC4 titanium alloy is susceptible to tribocorrosion, which can shorten the service life of components. This paper employs an electrochemical anodic oxidation treatment of the TC4 titanium alloy and a ceramic adhesive to fabricate a TC4 anodic oxidation/carbon fiber composite (CFCM) to address this challenge. Hence, A systematic study has been conducted on the friction and wear behavior of TC4 titanium alloy in artificial marine and air environments, focusing on exploring the tribocorrosion behavior and their intrinsic mechanisms in marine environments. The corrosion behavior of the TC4 titanium alloy was determined through kinetic potential polarization analysis. The results indicate that the anodized/carbon fiber composite can significantly enhance the tribocorrosion resistance of the material. Two orders of magnitude reduce the passivation corrosion density, and the corrosion potential increases to -0.136 V compared to the TC4 substrate. Furthermore, the wear mechanism is predominantly characterized by abrasive wear. This study offers novel insights for optimizing the selection of anticorrosive materials and designing coatings in marine engineering.
