Abstract

The corrosion resistance and bioactivity of titanium-hydroxyapatite (Ti-HA) composites prepared by mechanical alloying (MA) followed by spark plasma sintering were investigated. Potentiodynamic polarization tests showed that Ti composites containing 0-10% HA exhibited higher corrosion resistance than commercially pure Ti. An increase in HA concentration (20-30%) decreased corrosion resistance owing to the craterlike defects induced by ceramic particle detachment. Increasing MA time significantly reduced defect density and improved corrosion resistance. Bioactivity test on Ti HA composites in simulated body fluid revealed the growth of a nano-HA layer, which indicates the high potential of Ti-HA composites for application in biomedical implants.
