Bulk metallic glasses (BMG) for biomedical applications—A tribocorrosion investigation of Zr55Cu30Ni5Al10 in simulated body fluid

Bacterial adhesion on amorphous and crystalline metal oxide coatings

“…The role of the atomic arrangement or atomic ordering; crystalline versus amorphous, has not been of interest partially because metallic implants are generally crystalline and their native oxide films are so thin that their structural organization is not well defined. However, nowadays the development of amorphous metals is an important research area due to their extraordinary mechanical and corrosion resistance properties [21,22]. Similarly, the use of biocompatible coatings to improve the biological response of the implants is an emerging area, in which the synthesis of crystalline or amorphous coatings is possible [23][24][25].…”

Tribological behaviors of Zr-based bulk metallic glass versus Zr-based bulk metallic glass under relative heavy loads

“…Within the group of ZrTiCuNiBe alloys, Vit alloy 1 (Vit 1) with the composition of Zr 41 Ti 14 Cu 12.5 Ni 10 Be 22.5 exhibits the best comprehensive properties and has attracted the most attention [11e16]. Owing to these excellent properties mentioned above, BMGs are considered promising structural materials in future engineering [17e19] and biomedical applications [20,21]. However, to allow for a wide-spread use as structural materials, BMGs should have excellent combination properties, and their friction and wear property should be considered as well.…”

“…[48]. In addition, it exhibits good wear resistance, high hardness and high specific strength [37]. It showed to have the same hardness of GCr15 (HRC 60-63), but has higher compressive strength (1900 MPa) and higher fracture toughness (55-59 MPa) [46], Table 11: Mechanical properties of Zr-based BMG compared to Ti6Al4V.…”

“…Numerous researches focused on improving the performance and durability (nowadays an average 10-15 years lifetime) of biomedical implants [37]. In case of metals, the poor bioactivity and the release of toxic ions in the human body are the main challenges facing metallic implants.…”
