Abstract: The present invention relates to a biocompatible implant coated with a biocompatible fluor-hydroxyapatite and a coating method of the same, and in particular to a method for coating a hydroxyapatite(HA) and a fluor-hydroxyapatite on a biocompatible implant Ti metal substrate having an excellent biocompatibility and mechanical property and a biocompatible implant coated based on the above method. It is possible to maximize of an apatite itself and a biocompatible activation characteristic of a substrate in such a manner that an apatite is coated on a titanium substrate having a high mechanical physical property by a sol gel method. It is possible to adjust a biocompatible activation based on a solubility difference of two kinds of apatites by coating a double layer of a hydroxyapatite and a fluor-hydroxyapatite.
