“…The electrochemical results indicate that partial replacement of Co by Ag is effective in improving the corrosion resistance of the glassy Zr-Al-Co alloy in PBS. 31 BMGs over the wide binding energy region showed peaks of zirconium, aluminum, cobalt, silver, oxygen, and carbon, while no peaks of silver was observed for Zr 53 Al 16 Co 31 BMG. The C 1s spectrum showing a peak at around 285.2 eV is from contaminant carbon on the top surfaces of the specimens.…”

“…Ti-6Al-4V alloy, known as a widely used biomaterial based on its excellent biocompatibility and high corrosion resistance, was employed as a reference material. The absorbance of Zr 53 Al 16 Co 31 and Zr 53 Al 16 (Co 0.75 Ag 0.25 ) 31 BMGs is comparably high with that of the Ti-6Al-4V alloy, indicating their high cell viability and proliferation activity.

“…The low cytotoxicity of Zr-Al-Co-Ag BMGs can partly be attributed to their high corrosion resistance. The corrosion behavior and biocompatibility of metallic glasses or commercial metallic biomaterials have been extensively studied, the results show that high corrosion resistance of alloys can decrease the ions release in corrosive solution, which may resulting in their good biocompatibility [30][31][32][33][34]. For example, the study of metal ions release during corrosion of FeCobased amorphous metallic materials show that the total metal ions release of the amorphous alloys in PBS solution decreases with increasing corrosion resistance of those alloys.…”

“…Master alloys with nominal compositions of Zr 53 Al 16 (Co 1 − x Ag x ) 31 (described in atomic percentage, x = 0, 0.1, 0.25) were prepared by arc melting the mixtures of pure Zr, Al, Co, and Ag metals under Tigettered high-purity argon atmosphere. From the master alloys, the rods of 3 mm in diameter and 50 mm in length and sheets with a size of 10 mm × 50 mm × 1 mm were prepared by injection copper mold casting under argon atmosphere.…”

The aim of this paper was to investigate the effect of increasing cobalt content on the corrosion resistance of the FeCo-Cr-B-Si alloys in dilute mineral acids. The corrosion rates in 0.5N HCl, 1N HCl and 1N H 2 SO 4 significantly decrease with an increase in cobalt content. The alloys with a larger amount of cobalt can passivate spontaneously. The high corrosion resistance of the Fe-Co-Cr-B-Si alloys is also due to the formation of chromium -enriched passive film. Generally, the corrosion resistance of chromium -bearing alloy is improved by alloying with various metalloids but it is lowered by addition of boron and silicon. The corrosion behaviour of the amorphous Fe 75-x Co x Cr 1 B 7 Si 17 alloys obtained by the melt-spinning technique was studied using gravimetric method. The best results were obtained with Fe 65 Co 10 Cr 1 B 7 Si 17 alloy. The studied amorphous alloy ribbons exhibit not only excellent physical properties which are useful for many electric and magnetic applications: magnetic sensors, power transformers, high frequency transformers, etc., but also a very good corrosion resistance which extend their application domain.

Efecto del cobalto en el comportamiento de la corrosión de aleaciones amorfas Fe-Co-Cr-B-Si en ácidos minerales diluidos ResumenEste trabajo presenta los resultados de la investigación sobre la resistencia a la corrosión de un nuevo sistema de aleaciones amorfas, p. ej., Fe-Co-Cr-B-Si. El comportamiento de la corrosión de aleaciones amorfas así como el de cualquier otra aleación cristalina puede ser determinado, en ambas, por factores internos (la estructura y composición de la aleación) y por factores externos (tipo medio agresivo, concentración y coeficiente pH). La falta de cristalinidad y de defectos específicos al estado de cristalinidad -limitaciones de grano, dislocaciones y segregaciones-aseguran una alta resistencia a la corrosión a las aleaciones amorfas, en lugar de ser termodinámicamente metaestables La investigación se desarrolló a través del método gravimétrico en muestras de aleación amorfa Fe 75-x Co x Cr 1 B 7 Si 17 obtenidos por la técnica de centrifugado. Esta investigación muestra la influencia de la composición química de la aleación, por ejemplo, el porcentaje de cobalto y el medio de trabajo 0,5N HCl, 1N HCl y 1N H 2 SO 4 en la resistencia a la corrosión. Los mejores resultados fueron obtenidos con Fe 65 Co 10 Cr 1 B 7 Si 17.

The prospect of Zr‐based metallic glasses (MGs) in achieving a combination of properties, such as excellent electrochemical properties and extended biocompatibility, has been studied in this work. The combinatorial method (magnetron co‐sputtering) has been adopted to fabricate two novel quaternary MG systems (Zr50Ti32Cu13Ag5 and Zr40Ti37Co12Ni11) with optimized compositions. The structural analysis has been performed by the grazing incidence x‐ray diffraction and high‐resolution transmission electron microscopy to affirm the disordered structure of the MG systems. The electrochemical analysis demonstrates lower corrosion‐ (0.10 and 0.04 μA cm−2), and passive (2.93 and 1.88 μA cm−2) current densities of the MGs. In addition, the MGs are found to have higher charge transfer resistance (4.70 and 7.86 MΩ cm2) compared to the 316L stainless steel (SS) (0.15 MΩ cm2) and cp‐Ti (0.53 MΩ cm2). The electrochemical features are indicative towards higher corrosion‐resistance capabilities of Zr50Ti32Cu13Ag5 and Zr40Ti37Co12Ni11 MGs to prevent adverse biological reactions. Additionally, the cell proliferation analysis manifests higher cell proliferation on the Zr50Ti32Cu13Ag5 and Zr40Ti37Co12Ni11 MGs for the MC3T3‐E1 preosteoblast cells. Besides, the MTS assay analysis strengthens the prediction of cytocompatibility of the MGs. The integration of such unique properties makes these MG systems ideal candidates for biomedical implants.
