This article reports on the tribological performance of a WC/C multilayer coating with a periodicity WC/C = 15/5 nm deposited on bearing steel substrates. These substrates were initially polished to achieve different RMS roughness values ranging from 15 to 900 nm. Tribological tests were performed using a precision reciprocating microtribometer under ambient conditions with a steel ball as a counter-sample...
This paper investigates the influence of the applied load and sliding velocity on the microfrictional properties of native oxide-covered Si(100) and Si(100) coated with octadecyltrichlorosilane (OTS) and perfluorodecyltrichlorosilane (FDTS) self-assembled monolayers (SAMs) using a precision microtribometer. Microfriction was investigated as a function of the applied load and sliding velocity. As...
