Effect of Copper Inclusion Antibacterial Behavior, Corrosion Resistivity of Calcium Silicate Coatings
The study focused on the effect of copper (Cu2+) inclusion on the bioactivity, antibacterial behavior, corrosion resistivity and leaching characteristics of calcium silicate coatings on titanium metal. The process of stoichiometric CaSiO3 and ﬁve different concentrations of Cu2+ substitutions in CaSiO3. The incorporation of Cu2+ in the crystal lattice of CaSiO3 was examined by means of the Rietveld reﬁnement technique. The limit of Cu2+ in the crystal lattice of CaSiO3 was determined as 4.399 wt% of Cu2+ and the increased level of Cu2+ substitution result in the form of an additional phase of tenorite (CuO). The fabrication of stoichiometric CaSiO3 and Cu2+ substitutions in CaSiO3 coatings on Ti metal was achieved through an electrophoretic deposition technique and no change was noted until the heat temperature reached 800 ○C. Immersion tests of CaSiO3 coatings in simulated body ﬂuid solution resulted in the layer within 3 days of immersion. Antibacterial tests show pure CaSiO3 powders did not exhibited any antibacterial activity and the presence of Cu2+ in CaSiO3 resulted in good activity against E. coli and S. aureus. Potentiodynamic polarization tests performed on the Cu2+ doped CaSiO3 coatings resulted in its better corrosion resistivity when compared to the pure metal and dissolution tests performed on coatings.
