The corrosion behavior of the bulk glassy samples of Ca₆₅Mg₁₅Zn₂₀ alloy was studied by electrochemical measurements and immersion tests in a simulated body fluid, physiological fluid, and the Ringer solution. The results of immersion show that the volume of H₂ evolved after 2 h in simulated body fluid (29.8 ml/cm²) is the highest in comparison with the results of measurements conducted in physiological fluid (11.3 ml/cm²) and the Ringer solution (7.4 ml/cm²). The electrochemical measurements indicated a shift of the corrosion potential (E_{corr}) from -1.58 V for plate tested in a physiological fluid to -1.56 V and -1.54 V for samples immersed in the Ringer solution and simulated body fluid, adequately. The X-ray diffraction measurements were used to determine composition of corrosion products. The corrosion products were mainly identified to be calcium carbonates and calcium/magnesium hydroxides.
