Abstract
Commercial pure titanium discs were subjected to sandblasting using varied treatment jet angles, and the samples were subsequently modified by plasma electrolytic oxidation to optimize both mechanical and electrochemical modifications. The coating morphology, real-time images, chemical composition, thickness, microhardness, roughness, and electrochemical behavior were characterized and investigated to research the microstructures and properties comprehensively. Research results demonstrate that an optimal jet angle in sandblasting led to improvements in coating topography, phases, and deposition, contributing to enhanced surface mechanical and anticorrosion performances. The further enhancement of the titania coating properties was attributed to the optimized hybrid electrochemical-mechanical-treatment.
