(a,b) of the lubricants (MACs and MACs+G) before and after irradiation, the corresponding wear volume (c) (Red, AO; Green, UV; and Blue, EL), friction curves (d) under low and high temperature (–100 °C and 170 °C) as well as friction curves (e) and 2D morphology (f) of the worn tracks with long duration (56 h and more than one millions sliding passes).
