Silane/TiO 2 coating to control the corrosion rate of magnesium alloys in simulated body fluid

Abstract

A silane-based coating modified with titanium IV iso-propoxide was developed to slow down the corrosion rate of AZ31 and ZE41 magnesium alloys intended as biodegradable implants materials. Electrochemical impedance spectroscopy (EIS) was used to monitor the corrosion evolution over 7 weeks in simulated body fluid at 37 °C. A homogeneous crack-free 3 μm-thick coating provided corrosion protection for 2 and 3 weeks to the ZE41 and the AZ31, respectively. The corrosion mechanisms and the nature of the corrosion products of the coated systems are discussed and correlated to the coating morphology before and after the immersion tests.
