Selecting super hydrophilic phosphate masses coatings electrodeposited on titanium for medical applications

Abstract

In order to elaborate a very strong hydrophilic phosphate masses coating on titanium, an electrodeposition method was performed after polishing, etching and ultrasonication of samples. Electrodeposition took place in three electrodes cell at different working parameters (time and temperature). After electrodeposition all samples were calcinated for 1 hour at 4000C, in order to increase the crystalinitty and the purity. The coating characterization has included FT-IR SEM, XRD, AFM, and contact angle determinations and has indicated a rough coating with plaques crystals and small needles of HAP, good ratio Ca/P, and superhydrophilic character. The high surface energy denotes good bioadhesion.
