Original Abstract

Biodegradation properties of magnesium and its alloys that can be used for implants are not satisfactory and cause serious problems. These problems can be solved by biodegradable surface coatings. Evaluation of biodegradation process of Mg-3Al-1Zn alloy surfaces after grinding and grinding followed by potential controlled electrodeposition of dicalcium phosphate dihydrate (DCPD) was investigated by electro-chemical impedance spectroscopy measurements in this study. The potentiostatic electrodeposition treatment process was performed in water solutionof Ca(NO3)2.4H2, NH4H2PO4and H2O2. The corrosion process on treated and nontreated samples after various exposure times wasevaluated in 0.9% NaCl solution simulating body fluid environment at 37 °C.

Keywords
