Colloidal-sol gel derived biphasic FHA/SrHA coatings

► FHA/SrHA biphasic coatings on Ti substrate are prepared by sol-gel method. ► Solubility and adhesion strength of biphasic coatings is tailored by SrHA amount. ► The dispersion of SrHA in FHA promoted growth and attachment of osteoblast cells. ► FHA/SrHA biphasic coatings are to be advantageous in bioactivity and longevity.
