CHARACTERIZATION OF LASER CLADDING CALCIUM PHOSPHATE COATINGS ON TITANIUM SUBSTRATE
Laser cladding has become an extensively attractive technique in the field of biomaterials. Significant effort has been devoted to combine mechanical properties of metal with biologic properties of bioceramic by this technique. The paper described the gradient bioceramic coatings on titanium alloy substrate (Ti-6Al-4V) obtained by laser cladding. The surface and cross-sections morphology of the composites was observed by scanning electron microscope (SEM). The element distribution of calcium phosphate coatings were investigated by electron probe microscopic analyzer (EPMA). Phase composition of the coatings was analyzed by X-ray diffraction (XRD). Microhardness tests also were performed. These analyses showed that the obtained coatings surface was homogeneous with well phase composition, and the coatings structure was gradual variation as well as a good microhardness distribution.
