dc.description.abstract | New resorbable Ca32Mg12Zn38Yb18-2xBxAux (x = 1,2) alloys were designed and prepared in order to verify
their use for medical applications as potential short-term implants. Their amorphous structure containing
some crystalline phases (CaZn, CaZn2 and MgZn) was determined by X-ray and neutron diffraction
and electron microscopy methods. The biocorrosion behavior of the plates was tested by hydrogen evolution
measurements, immersion, electrochemical polarization tests, and electrochemical impedance
spectroscopy in Ringer’s solution at 37 C. The corrosion analysis was also supplemented by X-ray diffraction,
photoelectron, and ICP-AES spectroscopy. The corrosion resistivity measurements revealed that the
alloys manifest enhanced corrosion resistance. The corrosion current density for Ca32Mg12Zn38Yb18-
2xBxAux (x = 1, 2) alloys were 18.46 and 8.79 lA/cm2, which is lower than for pure Mg (47.85 lA/cm2)
and Zn (33.96 lA/cm2). A decreasing tendency for hydrogen to evolve as a function of time was noted.
The hydrogen evolution did not exceed 1 ml/cm2 over 1 h and average corrosion rate is calculated as
0.32 g/m2 . h for Ca32Mg12Zn38Yb14B2Au2 alloy after 312 h. The corrosion mechanism of the alloys
includes an anodic dissolution, a hydroxide precipitation, corrosion product layer formation and corrosion
propagation stage. | pl_PL |
