Later on, Fleischauer and Hilton [129] discussed the space tribology applications which included sliding motion, combined sliding and rolling motion of mechanisms in heavy load and high-speed conditions. Fusaro and Khonsari [130] presented the review for space lubricants, lubrication mechanisms, environmental effects, additives and bearing failures. The tribological behaviour of PFPE lubricants (Krytox, Demnum and Fomblin-Z) in steel/steel surface interface under vacuum environment has been analysed [131]. Low wear resistance was observed in vacuum environment compared to air environment. High wear resistance was observed for krytox lubricant in air for different load conditions. High wear resistance was observed for both Demnum and krytox lubricants in vacuum for high load conditions. The Fomblin-Z lubricant observed low wear resistance and low CoF.
