Development and Tribo-Mechanical Behavior of Functionally Graded Dust Tolerant Metal Matrix Composites Via Additive Manufacturing (Funding Agency: NASA, Research Collaborators: Marshall Space Flight Center NASA and United Tribes Technical Collage)

Long-term human presence on the moon has always been an ambitious topic for several space agencies. To fulfill this groundbreaking endeavor, NASA has launched a separate mission named Artemis Program. Some of the mission goals such as long-term human inhabitable structures, a south pole base camp, to bring several lunar probes and mobile habitats require long operating life in the harsh lunar environmental conditions. One of the major challenges in hardware components is the ability to protect surfaces against dust storms. From a tribological perspective (study of friction, and lubrication), the surfaces should have reasonable erosive wear resistance. Aluminum 6061 alloy is a widely used alloy in the space sector. In this project, we are investigating the potential of laser-based additive manufacturing techniques to fabricate erosive wear-resistant or dust-tolerant surfaces for future lunar exploration. Although aluminum is lightweight and has good ductility, it usually presents low erosion resistance and lower hardness. Multi-feeder laser powder blown directed energy deposition (DED) process provides the ability to develop metal matrix composites where selected particles can be incorporated into the aluminum to enhance target mechanical properties.
