Bioceramic coatings on titanium alloy (TC4) is fabricated with the powders of CaCO3,CaHPO4·2H2O and Ti by laser cladding and heat treatment. Phase analysis by X-ray diffraction (XRD) indicates that the main compose of transitional coating is CaTiO3, and the ceramic coating without heat treatment is tetracalcium phosphate (TTCP), the ceramic coating after heat treatment is hydroxyapatite (HA). It can be conclude that laser power has a greater impact on the composition of coating than scanning speed. The heat treatment process at temperature 800 ℃ for 4 hours and furnace cooling can promote the regeneration of HA and effectively increase the content of HA in ceramic layer. The HA content of coating fabricated with Ca/P2.00 powders is higher than those of others.
