dc.description.abstract | Porous titanium implants can be a good solution to solve the stress shielding phenomenon.
However, the presence of pores compromises mechanical and corrosion resistance. In this work,
porous titanium samples obtained using a space-holder technique are coated with Chitosan, Chi-
tosan/AgNPs and Chitosan/Hydroxyapatite using only one step and an economic electrodeposition
method. The coatings’ topography, homogeneity and chemical composition were analyzed. A study
of the effect of the porosity and type of coating on corrosion resistance and cellular behavior was
carried out. The electrochemical studies reveal that porous samples show high current densities
and an unstable oxide film; therefore, there is a need for surface treatments to improve corrosion
resistance. The Chitosan coatings provide a significant improvement in the corrosion resistance, but
the Chitosan/AgNPs and Chitosan/HA coatings showed the highest protection efficiency, especially
for the more porous samples. Furthermore, these coatings have better adherence than the chitosan
coatings, and the higher surface roughness obtained favors cell adhesion and proliferation. Finally,
a combination of coating and porous substrate material with the best biomechanical balance and
biofunctional behavior is proposed as a potential candidate for the replacement of small, damaged
bone tissues. | es |
