In-Depth Information
The corrosion resistance increases (decreases the corrosion
current) for the etched and with HA deposited nanocomposites, with
respect to not etched materials. The best passivation (lowest current
and wide plateau in the passive range) shows samples marked as
c and d on both Figs. 5.28 and 5.29. These samples have lat and
porous surface covered with Ca-P, respectively. After corrosion test, a
large part of the particles deposited on lat surface was removed
from the surface, which they were not observed on the porous
nanocomposite [19].
Figure 5.28 Potentiodynamic corrosion curves for Ti-glass nano-
composites: lat (a), porous (b), lat with HA (c), porous with
HA (d); (HA deposited using HA + HCl electrolyte) [19].
Figure 5.29 Potentiodynamic corrosion curves for Ti-glass nano-
composites: lat (a), porous (b), lat with HA (c), porous with
HA (d); (HA deposited using Ca(NO 3 ) 2 + (NH 4 ) 2 HPO 4 + HCl
electrolyte) [19].
