Radiation-Induced Lubricant Degradation Pathways in Spacecraft Tribosystems

Description

Expert lecture on radiation-induced degradation of spacecraft lubricants. Covers space radiation, PFPE oils and greases, MoS2 films, accelerated beam testing, and post-irradiation characterization. Contrasts radiation chemistry with thermal oxidation, details performance impacts, and maps chemical-structure sensitivities. Presents mitigation, modeling with G-values, and mission-specific tailoring for Moon, Mars, and deep space. Includes practical reliability testing and implementation guidance.
