Sažetak
Many reasons make magnesium and its alloys the best potential materials for biodegradable implants: (i) magnesium is an essential element to humans and beneficial for bone strength ; (ii) magnesium degrades in physiological solutions ; and (iii) the mechanical properties of magnesium are similar to those of natural bone. Unfortunately, magnesium is very susceptible to corrosion in physiological solutions and its mechanical properties decrease before the new tissue has healed. Various surface treatments have been applied to magnesium and its alloys to improve their corrosion resistance and the lifetime of implants. It has been also found that pre-treatment methods are very important for the protection of magnesium against corrosion. Pre-treatment methods remove the passive oxide layer that forms easily due to the high reactivity of Mg and has a detrimental effect on coating adhesion and uniformity. Because of its relatively easy preparation from aqueous solution and stability at oxidized state, polypyrrole and its derivatives are reported to be one of the most important candidates for corrosion protection. In this study, the polymeric coating (polypyrrole) was formed on the magnesium alloy by electrochemical polymerization from aqueous solution of sodium salicylate. The protection efficiency of the polymeric coatings was investigated in a simulated physiological solution (Hanks’ solution) using voltammetry and electrochemical impedance spectroscopy methods. The structural characteristics of the surface coatings were investigated by the FTIR technique.
