Resumen:
In the development of new materials for use in mechanical heart valves there are conditions thatmust be satisfied. In particular for the present report the focus is, particularly, in good surfacequality, mechanical and corrosion resistance and biocompatibility for the intended period of use.The material object of this investigation is titanium oxide deposited on a substrate of Ti-6Al-4V.The oxide films were deposited by the sol-gel technique by dip-coating, withdrawing at aconstant velocity, drying and thermal treatment.The films were characterized by optical and scanning microscopy observations and test ofadhesion. The adhesion of the films were determined as a function of the number of layersdeposited and also in relation with the surface morphology. The results show that the mono-layerfilms have much better adhesion than the multilayer films.The films show cracks in the border of the samples which density number was reduced using a 6months aged sol and covering the border with an acrylic resin.
