Paper Title:
Corrosion Behavior of TiO2 Coating on Magnesium Alloy AM60 in Hank’s Solution
  Abstract

As magnesium is an essential element for the human body, magnesium alloys are expected to be promising implant materials despite their lower corrosion resistance. The most potential advantages of magnesium lie on both excellent biocompatibility and good mechanical properties. A TiO2 coating had been successfully deposited on the surface of AM60 samples by using a thermal spray technique and was then sealed with sodium silicate. The corrosion behavior was investigated by using the potentiodynamic electrochemical technique. The experimental results demonstrated that the TiO2 coating had a porous ceramic structure. The thickness and micro hardness of the layer reached 40 μm and 886 HV, respectively. After additional sealing with sodium silicate, TiO2 coating on magnesium alloy improved corrosion resistance in Hank’s solution.
