- Abstract
The aim of the present work was to characterize the influence of the surface conditioning treatment of a medical grade Ti6Al7Nb alloy substrate on the homogeneity, morphology and adhesion strength of hydroxyapatite coatings. The substrates were obtained by means of a Selective Laser Melting process using different laser powers. The deposition of hydroxyapatite was performed by dip-coating, followed by a heat treatment at 600°C for 30 min., in air. The morphology of the coatings was studied by means of scanning electron microscopy. Bonding strength was evaluated by pull-off tests.
