<p>Bulk metallic glasses (BMGs) have been proved to be a new family of materials that possess unusual atomic arrangements and exceptional mechanical properties against traditional crystalline alloys. The composition of alloys and environmental conditions greatly influences their corrosion resistance. This review captures prevailing knowledge on the corrosion behavior of BMGs in aqueous and physiological solutions. Focus is given to zirconium-, titanium-, magnesium-, copper-, and calcium-based BMGs, which are of interest for biomedical and structural uses. The influence of alloying elements on determining the stability of the passive film, susceptibility to localized corrosion, and resistance to pitting is discussed. Emphasis is placed specifically on the corrosion response of BMGs in bio-applications, where parameters like biocompatibility, ion release, and localized corrosion are significant to enable their viability as implant materials. Results from electrochemical characterization and in vivo tests are integrated to offer mechanistic explanations of corrosion mechanisms. The knowledge of the corrosion behavior of these materials, thus such an understanding of the application of metallic glasses in various environments, is required for both designers and engineers.</p>
