Original Abstract

The long-term chemical degradation of magnesium alloys AZ31 and AZ61 processed by method squeeze casting in simulated body fluid solution (SBF) were evaluated in depending on alloy compositions, time duration, and released amount of degradation products and pH level changes. The chemical degradation was realized during several time intervals from 24 to 1008 hours and alloys AZ31 and AZ61 were immersed in Hank's solution with various salt concentrations. The pH changes were determined electrochemically; alloys compositions and released amount of degradation products were determined using spectrometrically (GDS glow discharge emission spectrometer and AAS atomic absorption spectrometry). The results confirmed the important role of chemical heterogeneity of AZ31 and AZ61, type of SBF and time dependence of degradation.
