摩擦界面その場SEM観察法とその観察例

抄録

In-situ observation of friction interfaces using electron microscopy are necessary to clarify friction mechanisms. Although transmission electron microscopy (TEM) can be used to observe friction interfaces, TEM obtains only side views of friction interfaces. Current observation methods using scanning electron microscopy (SEM) cannot obtain friction interfaces from a top view. A novel method for in situ SEM observations of friction interfaces, from a top view has been developed using an electron transmission film and a microtribometer. In this review, in situ observations of friction interfaces between electron transmission films and nanodiamond, graphene oxide, and polyacetal in dry are explained. Moreover, those between electron transmission films and SUJ2 balls in poly alpha olefin, under boundary lubrication, are also explained. SEM observations and energy dispersive X-ray spectroscopy (EDS) measurements of the friction interfaces are discussed.
