Surface Forces Apparatus in Nanotribology

摘要: The Surface Forces Apparatus (SFA) has proven to be an excellent tool for research in nanotribology. It allows the study of single or multiple asperity contacts lubricated not. normal load, contact area and sliding velocity between surfaces can controlled unambiguously measured with higher accuracy than any conventional tribometer. Furthermore, image obtained as are slid, allowing monitoring real size shape distance film thickness profile when atomically smooth used. is relatively simple perform a comprehensive exploration full space parameters determine important variables frictional behavior system. In this chapter principles operation some experimental details nanotribometer described.
