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 70oC. (b) Differences of average current evolution of HA films electrodeposition on superhydrophilic VACNT films and NiTi alloys in solution temperature kept at 23 and 70ºC.
