dc.description.abstract | The corrosion activity of amorphous plates of Ca60Mg15Zn25 alloy was investigated. The biocompatible elements
were selected for the alloy composition. The electrochemical corrosion and immersion tests were carried out in a
multi-electrolyte fluid and Ringer's solution. Better corrosion behavior was observed for the samples tested in a
multi-electrolyte fluid despite the active dissolution of Ca and Mg in Ringer's solution. The experimental results
indicated that reducing concentration of NaCl from 8.6 g/dm3 for Ringer's solution to 5.75 g/dm3 caused the
decrease of the corrosion rate. The volume of the hydrogen evolved after 480 min in Ringer's solution (40.1 ml/
cm2) was higher in comparison with that obtained in a multi-electrolyte fluid (24.4 ml/cm2). The values of opencircuit
potential (EOCP) for the Ca60Mg15Zn25 glass after 1 h incubation in Ringer's solution and a multielectrolyte
fluid were determined to be −1553 and −1536 mV vs. a saturated calomel electrode (SCE). The
electrochemical measurements indicated a shift of the corrosion current density (jcorr) from 1062 μA/cm2 for
the sample tested in Ringer's solution to 788 μA/cm2 for the specimen immersed in a multi-electrolyte fluid. The
corrosion products analysis was conducted by using the X-ray photoelectron spectroscopy (XPS). The corrosion
products were identified to be CaCO3, Mg(OH)2, CaO, MgO and ZnO. The mechanism of corrosion process was
proposed and described based on the microscopic observations. The X-ray diffraction and Fourier transform
infrared spectroscopy (FTIR) also indicated that Ca(OH)2, CaCO3, Zn(OH)2 and Ca(Zn(OH)3)2·2H2O mainly
formed on the surface of the studied alloy. | pl_PL |
