With the objective of producing a new generation of biomaterials, titanium alloys submitted to glow discharge nitriding were used as a substrate to obtain hydroxyapatite coating, deposited by means of pulsed laser deposition. Hydroxyapatite layers were deposited at room temperature by means of the excimer ArF laser (λ=193nm) working at a frequency of f=15 Hz. The pressure in the experimental chamber was p≈3×10-5 hPa. The deposited layers underwent heat treatment at 490°C and 600°C. A scratch test showed high adhesion of the deposited hdroxyapatite layers after heat treatment at 600°C.
