Space Plasma Ion Processing of Ilmenite in the Lunar Soil: Insights from In-situ Tem Ion Irradiation Experiments

Introduction: Space weathering on the moon and asteroids results largely from the alteration of the outer surfaces of regolith grains by the combined effects of solar ion irradiation and other processes that include deposition of impact or sputter-derived vapors. Although no longer considered the sole driver of space weathering, solar ion irradiation remains a key part of the space weathering p...

Electron Energy-Loss Spectroscopy of Iron Nanoparticles in Lunar Soil using an Aberration-Corrected Scanning Transmission Electron Microscope

Introduction and Motivation: Mineral grains on the surfaces of airless planetary bodies like the Moon are subjected to continuous radiation processing from solar energetic ions and also experience micrometeorite impact events. Together these processes alter the morphology, chemistry, and microstructure of surface particles and are collectively known as space weathering [1]. The optical properti...

Important Considerations for Lunar Soil Simulants

Lunar samples are not readily available for In-Situ Resource Utilization (ISRU) studies, necessary for preparations for a return to the Moon with landers, robots, and astronauts. Lunar soil simulants have been produced as substitutes for the real thing; BUT how good are they? JSC-1 and 1A were produced only to approximate the geotechnical properties of lunar soil, with its natural glassy compon...

Synthesis oF Fe-TiC Hard Coating From Ilmenite via Laser Cladding

The aim of this work was to synthesize TiC reinforced coating on carbon steel via reduction of ilmenite powder. A mixture of ilmenite and graphite was pre-placed on AISI 1020 steel surface. The effect of the addition of excess graphite amounts on the progress of synthesis of carbide particles was studied. The evolution of phases in different coatings was analysed via X-ray diffraction and scann...
