Anodic oxidation is a prevalent technique to introduce superior corrosion and wear resistance upon the surface of titanium (Ti) alloys,in which the selection of appropriate electrolytes and defect-sealing strategies is a key.This study aims to address such issues through anodizing Ti-10V-2Fe-3Al alloy in malic acid,followed by a post-sealing treatment with Mg-Al layered double hydroxides (LDHs).The characteristics of the samples were investigated using scanning electron microscopy (SEM),atomic force microscopy (AFM),glow discharge optical emission spectroscopy (GDOES),X-ray diffraction (XRD) and energy-dispersive X-ray spectroscopy (EDS).SEM micrographs reveals that the anodic coating had a surface full of bulges and cracks,and was almost sealed by the following LDHs treatment.XRD pattern indicate that the anodic coating was mainly consisted of amorphous TiO2 with a small fraction of anatase,but its crystallization degree was increased through the post-sealing.Moreover,electrochemical and tribological measurements demonstrate that corrosion current density was 2.8 × 10-6,2.0 × 10-7,5.9 × 10-9A cm-2,and wear rate was 1.45 × 10 3,1.30 × 10-4 and 6.90 × 10-s mm3 N-1 m-1 for respective bare Ti10V-2Fe-3Al alloy substrate,anodized specimens without and with the LDHs post treatment.Finally,a plausible wear mechanism was proposed.
