In this study,the friction performance of self-lubricating material with the counterpartsteel ball-plate rubbing was investigated in vacuum conditions and the thermal distortion ofthe heat sink sample was tested.The analysis and test results show that the self-lubricating materialhas excellent anti-friction properties in high vacuum condition and can decrease the thermalstress and avoid damage to the PFCs during physical experiments.
