In-Depth Information
The EDS analysis of the surface after Ca-P removing shows Ca
and P components (Fig. 9.83), and Raja
et al
. suggest that calcium
phosphate grows from the bottom of the nanotubes rather than
just sticking on the top surface of the titanium oxide [75]. Calcium
phosphate coating on a polished lat titanium surface is extremely
weak, not uniform and is easily removed after washing [75].
Figure 9.83
EDS analyses of the tensile tested surface where the coating
was partially removed. The upper spectrum is for the Ca-
P coating. The lower spectrum is for the surface, where the
coating was removed (the peaks of Ca and P are still observed,
indicating that the calcium phosphate nucleated at the bottom
of the nanotubes) [75].
