Transformation of surface compositions of titanium during alkali and heat treatment with different vacuum degrees

Abstract

In this study, the alkali and heat treatment (AH) of titanium (Ti) at different ambient pressures (air as atmosphere pressure, 1 Pa and 10-3 Pa) was researched. The results demonstrated that in atmosphere condition the porous layers with rutile/anatase TiO2 formed on Ti surface, and at 1 Pa and 10-3 Pa conditions the more loose surface structures with large pore size and sodium titanate (Na1.7Ti6O11) was obtained. Particularly after AH at 1 Pa, the surface layer had the larger roughness, better wettability and easier hydroxyapatite (HA) deposition in simulated body fluid (SBF) than other conditions. Electrochemical evolution revealed the porous network structure on Ti surfaces formed during AH resulted in successive decreasing of corrosion resistance in SBF with increasing vacuum degrees. This investigation of AH technology of Ti at different chamber pressures would promote a more potentially clinical application of AH method.
