e data for downselection of hard-hard and hard-soft tribopairs, focusing on their ability to eject or thrash lunar regolith dust and resist abrasion. DLC and Ti-MoS2 averaged low friction (COF 0.18...

Lunar surface, especially that of a permanent Moon settlement. First identified during the Apollo missions, Lunar dust causes overheating, abrasion, and clogging of Lunar surface equipment and caus...

wear mechanisms are elucidated based on regolith particle impact velocity, impact angle (erosion), regolith morphology, and particle size (abrasion). The lack of research on how temperature affects...

include mineralogical and chemical composition, particle size distribution, density, shear strength, angle of repose, mass flow rates, and abrasivity. Results of data collection and analysis show t...

Additionally, this work provides new results for ESA s mare simulant, EAC-1. We provide data on particle size distribution, particle shape, abrasivity, density, water content, major and trace eleme...
