High-performance spacecraft components require advanced manufacturing and novel materials to push the state-of-the-art. Bulk metallic glasses (BMGs) are alloys that lack a crystalline structure, which result in superlative mechanical properties, high wear resistance, and the processability of thermoplastics. This combination of properties makes BMGs the material-of-choice for gears for extraterrestrial robotic exploration. In this talk, work regarding the development of BMG gears and the corresponding manufacturing specifications will be discussed.
