Abstract

•Porous Ti substrates were coated with hydroxyapatite by the sol-gel technique.•A HA porous thin films onto the porous titanium substrates was obtained.•The HA - porous Ti showed good mechanical interlocking and chemical bonding.•The HA coatings can prevent the corrosion of Ti substrate and make it bioactive.•The proposed HA coating on porous Ti allows a biofunctional and mechanical balance.
