The HA deposited from HA + HCl electrolyte has signiicantly
different morphology on micro-Ti-6Al-4V with respect to second
electrolyte. The HA layer has many cracks with small spherical
particles on top (Fig. 9.80a). For nano alloy, the HA layer covers the
alloy surface, but pores are still visible (Fig. 9.80b) [34].
