Metallic implants have weak surface properties, despite superior material properties in strength and elasticity. Therefore, different modification techniques studied in order to reduce the inflammation, clot, and allergic or toxic reaction during the interaction with tissues. Hydroxyapatite (HA), similar to calcium salts found in the bone, which have characteristic calcium phosphate structure, preferred as most coating material in metallic implants. However, direct application of HA is quite limited due to stiffness and low ductility when compared to tissue. Therefore, nowadays HA reinforced with metal oxide as TiO2, ZrO2 and AgNO3.
