Electrochemical analysis on localized corrosion of PEO/magnesium oxide coating
Source abstract
Abstract
Mg-Zn-Ca alloys have been identified as a promising biodegradable material for implants. However, their high corrosion rate causes unexpected failures. Plasma electrolyte oxidation (PEO) coating is an effective approach to reduce corrosion rate. MgO coating was applied by the PEO technique on the Mg-5Zn-0.4Ca alloy. The corrosion mechanism was investigated by impedance spectroscopy (EIS) and electrochemical noise (ECN). This paper aims to determine if PEO coating can improve the corrosion performance of this alloy during submersion. Additionally, it seeks to investigate whether pitting corrosion can be a weakness for these coatings, despite the inherent holes and cracks in this coating.
