Verification of tribo-reduction of copper oxide in phenolic composite material through visualization of friction surface

open access: yesNihon Kikai Gakkai ronbunshu, 2018
The surface of phenolic composite material was continuously observed through borosilicate glass (BK7) during friction to verify the tribo-reduction of copper oxide (CuO) taking place at the interface. Two types of pad samples were slid against a rotating
