Wettability and In Vitro Bioactivity Studies on Titanium Rods Processed by Equal Channel Angular Pressing

Commercial purity titanium (CP-Ti) was processed by equal channel angular pressing (ECAP) with a channel angle of 120° with the aim of studying the effect of microstructure on the wettability and bioactivity. Solid and tubular Ti rods of 6 mm diameter were ECAPed at room temperature. During ECAP of tubular specimens, hydroxyapatite was filled in the tube. Grains and sub-grains of size approximately 1 μm were observed using transmission electron...
