Sažetak
Magnesium and its alloys have some advantageous properties which make them an excellent choice for a number of applications. As the potential biodegradable materials, they show many advantages over current metallic materials and biodegradable plastics and ceramics. Biodegradable magnesium based implants in the human body can be gradually dissolved, absorbed, consumed or excreted, so there is no need for the secondary surgery to remove implants after the surgery regions have healed. Because of the high corrosion rates in physiological environment, protection coatings must be applied to the magnesium based alloys surface to prevent their prematurely degradation. In this study, the protection efficiency of the self-assemble monolayer of fatty acids (palmitic and stearic) formed on the anodized alloy samples were investigated in a simulated physiological solution (Hank’s solution) using voltammetry and electrochemical impedance spectroscopy methods.
