| Abstract Scope |
Dust threatens long-term durability of vehicles and structures operating on Lunar and Martian surfaces. Abrasion, erosion and jamming of mechanisms with mating surfaces, such as gears, hinges and other mechanical joints, were documented due to lunar dust incursion in Apollo missions. Furthermore, corrosion has been identified as another hazard to materials durability and performance of Martian rovers due to the presence of water and brine. Materials resistant to abrasive particles and corrosive environments are needed to enable human/robotic exploration of the Moon and ultimately Mars. Ternary metal boride (MAB) phase materials, such as molybdenum aluminum boride (MoAlB), are novel ceramics that possess high toughness and hardness, exceptional thermal conductivity and shock resistance with enhanced corrosion resistance observed in some MAB systems. Due to processing limitations, it is difficult to produce MAB parts via traditional fabrication methods. The feasibility of laser powder bed fusion additively manufactured MAB parts will be presented. |
