## Abstract A double‐layered coating, consisting of a hydroxyapatite (HA) outer film and a fluor‐hydroxyapatite (FHA) inner film, was produced on a Ti substrate by a sol–gel route to improve the biocompatibility and functionality of the system. Dissolution behavior of and __in vitro__ cellular resp
## Abstract Hydroxyapatite (HAP) based coatings on titanium alloy Ti6Al4V were attempted by sol–gel process. Precursor sol was dip‐coated onto the substrates and the formation of HAP as the main phase was ensured after the sintering of coatings at 900°C, as confirmed by the characterization studies
Sol-gel-derived zirconia films were deposited onto polished Ti-6Al-4V substrates by dip-coating from an alkoxide precursor solution. No change in morphology of the zirconia film was observed after aging at 37°C for 4 -12 weeks in pH 4.0 buffer solution or Hanks' balanced salt solution (HBSS), althou
