Abstract
In this research, Fluoridated hydroxyapatite bio-ceramic coatings were produced by laser cladding on the titanium alloy with hydroxyapatite and CaF2 as raw materials. The microstructures and phase constitutions of coatings were characterized by OM, SEM, EDS and XRD, the mechanical properties was investigated by micro-hardness and simulated body fluid immersion test. The results indicated that Fluoridated hydroxyapatite bio-ceramic coatings with anticipated structure and properties were achieved successfully by laser cladding on the titanium alloy. Compared with CO2 laser, the FHA coatings prepared by fiber laser had better deposition of biological activity phase.
