“…In terms of strength, the MGs are closer to the maximum theoretical value than any other known metallic material [ 27 ]. Additionally, they are characterized by increased corrosion resistance [ 28 , 29 , 30 , 31 ], as a result of grain boundary absence that reduces the possible corrosion routes and the common presence of alloying elements with the great ability to chemical passivation. This increase is also connected with nearly ideal chemical and structural (including lack of crystalline inclusions) composition homogeneity in the microscale [ 32 ], which reduces the number of galvanic micro-cells formed [ 33 ].…”

The continuous development of novel materials for biomedical applications is resulting in an increasingly better prognosis for patients. The application of more advanced materials relates to fewer complications and a desirable higher percentage of successful treatments. New, innovative materials being considered for biomedical applications are metallic alloys with an amorphous internal structure called metallic glasses. They are currently in a dynamic phase of development both in terms of formulating new chemical compositions and testing their properties in terms of intended biocompatibility. This review article intends to synthesize the latest research results in the field of biocompatible metallic glasses to create a more coherent picture of these materials. It summarizes and discusses the most recent findings in the areas of mechanical properties, corrosion resistance, in vitro cellular studies, antibacterial properties, and in vivo animal studies. Results are collected mainly for the most popular metallic glasses manufactured as thin films, coatings, and in bulk form. Considered materials include alloys based on zirconium and titanium, as well as new promising ones based on magnesium, tantalum, and palladium. From the properties of the examined metallic glasses, possible areas of application and further research directions to fill existing gaps are proposed.

“…It is mainly related to the absence of grain boundaries, which are easy corrosion paths. Furthermore, the homogeneity of the chemical composition of BMGs (and often the content of many passivating elements) is also a significant advantage, which influences the corrosion resistance of the alloys in physiological fluids and various aggressive solutions [ 30 , 48 , 49 , 50 ]. The exceptional corrosion resistance of many glassy alloys may go hand in hand with the enhanced biocompatibility, associated with the ability to be inert in the organism’s environment and the lack of cytotoxicity of the released ions [ 51 , 52 ].…”

Microstructure, mechanical properties, corrosion resistance, and biocompatibility were studied for rapidly cooled 3 mm rods of Zr40Ti15Cu10Ni10Be25, Zr50Ti5Cu10Ni10Be25, and Zr40Ti15Cu10Ni5Si5Be25 (at.%) alloys, as well as for the reference 316L stainless steel and Ti-based Ti6Al4V alloy. Microstructure investigations confirm that Zr-based bulk metallic samples exhibit a glassy structure with minor fractions of crystalline phases. The nanoindentation tests carried out for all investigated composite materials allowed us to determine the mechanical parameters of individual phases observed in the samples. The instrumental hardness and elastic to total deformation energy ratio for every single phase observed in the manufactured Zr-based materials are higher than for the reference materials (316L stainless steel and Ti6Al4V alloy). A scratch tester used to determine the wear behavior of manufactured samples and reference materials revealed the effect of microstructure on mechanical parameters such as residual depth, friction force, and coefficient of friction. Electrochemical investigations in simulated body fluid performed up to 120 h show better or comparable corrosion resistance of Zr-based bulk metallic glasses in comparison with 316L stainless steel and Ti6Al4V alloy. The fibroblasts viability studies confirm the good biocompatibility of the produced materials. All obtained results show that fabricated biocompatible Zr-based materials are promising candidates for biomedical implants that require enhanced mechanical properties.

“…Since these defects are commonly the culprits behind localized corrosion in crystalline alloys, it is believed that BMGs will be more resistant to pitting corrosion than their crystalline counterparts. Corrosion studies have shown that many Zr-based BMGs are vulnerable to pitting corrosion in chloride solutions [2][3][4][5][6][7][8][9][10]. Peter et al [3] investigated the localized corrosion behaviors of the Zr 52.5 Cu 17.9 Ni 14.6 Al 10.0 Ti 5.0 (atomic percent, at.%) BMG and its crystalline form (polished samples) in 0.6 M NaCl.…”
