Polymeric coatings were obtained polycaprolactone-chitosan. The coatings were applied by dip-coating technique, on Ti6Al4V substrates chemically treated with NaOH solution. Based on SEM morphological analysis and infrared spectra, it was observed that the amount of polycaprolactone in the coating obtained had an effect in retaining the chitosan on the surface, associated with the emission of R-OH bond and the morphological characteristics. Impedance spectra performed on the polymeric films showed phenomena related processes adsorption of ionic species to monolayer formation on the surface. These spectra showed equally charge transfer phenomena generated by the morphological characteristics of the coatings, such as its porosity, density and homogeneity. The coated substrate was immersing in SBF solution for 8 days, allowed to observe its adsorption capacity of calcium through nucleation and precipitation of calcium phosphates, bioactive character displaying a front medium.
