Figure 1: (a) Current-time profile during the deposition of HA films on superhydrophilic VACNT films and NiTi alloys in 0.042 molL-1 Ca(NO3)2.4H2O + 0.025 molL-1 (NH4)2HPO4 solution. Applied potential of -2.0 V (vs. Ag/AgCl), and solution temperature kept at 23 and 70°C. (b) Differences of average current evolution of HA films electrodeposition on superhydrophilic VACNT films and NiTi alloys in solution temperature kept at 23 and 70°C.
