| Abstract Scope |
As a type of biodegradable material, AZ31 magnesium alloy has attracted many attentions in the bio-implanting field. Depending on the actual applications, it is often necessary to modify the microstructure of materials to achieve different properties. It is critical to understand the relationship between microstructure and corrosion property of AZ31 magnesium alloy. Grain size is the microstructural feature studied in this work. Heat treatment was employed to obtain the samples with different grain sizes. Bio-corrosion test was conducted for the samples through being immersed in simulated body fluid for various time intervals. Scanning electron microscope was employed for observing morphology changes due to corrosion testing. The results show that the corrosion rates increased with the immersion duration for the samples, the samples with larger grain size exhibited better corrosion resistance, and the corrosion mechanisms for the sample was uniformly pitting corrosion. |
