The aim of the present article is to investigate the corrosion resistance of the Zr‐Ti‐Si‐O coatings (as‐deposited and annealed) as possible candidate as new biocompatible material. The coatings have been characterized in terms of elemental and phase composition, roughness and corrosion resistance in simulated body fluid (SBF) at 37 °C. The coatings, with a compositional ratio O/(Zr + Ti + Si) of 1.38, were found to consist of a mixture of ZrTiO4, ZrSiO4, Ti2O3, and SiOx phases. The samples annealed in O2 atmosphere at 1100 °C for 30 min resulted in improved crystallinity, increased surface area, surface roughness, and skewness. The results of the electrochemical tests revealed that Zr‐Ti‐Si‐O coatings had improved the corrosion resistance to the aggressive attack of the SBF as compared to the bare Ti6Al4V alloy, the best results being obtained on annealed coatings.

“…One of the proposed mechanisms for the drawback of Al and V alloying additions to Ti can be through the formation of a complex oxide structure in the environments due to the precipitation of aluminum and vanadium oxides along with the oxide of titanium . This complex oxide on Ti–6Al–4V alloy surface exhibits lower thermodynamic or kinetics stability than TiO 2 , which is formed on the pure metal …”

The effect of raftiline inulin in presence of Ca 2+ on titanium alloy as biomaterial was investigated in simulated body fluid solution at 37°C. The behavior of Ti alloy was studied at different concentrations of inulin with immersion time using electrochemical impedance spectroscopy and potentiodynamic polarization tests. Ti alloy was effectively inhibited by the addition of 0.25% by weight raftiline in presence of 10 À5 M calcium levulinate, which reacts with Ti alloy and forms a protective film on its surface. The results were confirmed by surface examination via scanning electron microscope.

“…In a previous study [1] it was found that Al behaves differently and its E p is not greatly sensitive to temperature (range 0-40 C). In other works [14,15], it has been found that E p of aluminum decreases with increasing temperature. The results of this study are in close agreement with the reported observation of Broli and Holtan [14].…”

“…There are some works concerning the influence of temperature on E p [10,11,[13][14][15]. In general, E p decreases with increase in temperature for all types of stainless steels, although the particular dependence on temperature depends on the grade of steel.…”

The dependence of the pitting potential (E p ) of aluminum on chloride concentration, pH and the temperature of the solution was studied by the potentiodynamic method according to a statistical experimental design. The parameters of the statistical E p model offered on the basis of Box-Wilson experimental design method were evaluated with the use of the experimental data. Comparison of the predicted values from the model with the observed values showed that the model is a good fit. From the model equation the most noble E p value of À 420 mV was obtained when Cl À ion concentration, temperature and pH of the solution were 57 ppm, 22 C, and 8.3 respectively. Box-Wilson experimental design technique was proved to be applicable in modelling E p of aluminum.
