| Abstract Scope |
Friction-induced energy dissipation poses a significant obstacle in space applications, especially during extended missions where energy losses accumulate and become substantial due to the limitations of lubrication in space. The Al6061 aluminum alloy stands out as a promising material for spacecraft component manufacturing due to its corrosion resistance, impressive strength-to-weight ratio, exceptional formability, and its inherent insensitivity to the harsh conditions of the extraterrestrial environment. There have been efforts to extend application of additive manufacturing for space applications but the tribological performance of additively manufactured components has not been extensively explored yet. In this effort, we will present how parts fabricated via two distinct AM techniques: large scale WAAM and meso-scale L-DED on friction and wear behavior in ambient and vacuum conditions. Additionally, in-depth characterization of worn our regions was conducted to explore the primary wear mechanisms in different conditions. |
