In Situ Studies of TiC1−x N x Hard Coating Tribology

Abstract: TiC 1-x N x hard coatings present time-dependent tribological behavior with an initial running-in period (500-2000 cycles) marked by an elevated friction coefficient, followed by [10000 cycles with low-friction and wear at room temperature (RT) in ambient air. The mechanisms behind this behavior are not completely understood. Tribological tests performed at RT and at different relative humidity (RH) levels revealed that a minimum value between 15 and 25% RH is needed to trigger the low-friction regime at a sli… Show more

“…There are various pathways for in situ analysis of a surface. In situ spectroscopies such as Raman spectroscopy have been used to analyze the chemical nature of the interactions by examining the wear surface or transfer films during sliding or just after it exits the contact without changing the environment [3,4]. In situ electron microscopy is increasingly popular; Varenberg used a scanning electron microscope to analyze the interaction at the interface from the side [5].…”

“…These extremely different loading conditions, the necessity of increased performance and the demand to master difficult-to-machine materials, have driven the specific development of wear-resistant coatings within the last three decades to meet the individual requirements of the given application. This has recently been related to the in situ formation of self-lubricious reaction layers after a short running-in period in dry sliding contacts ( Figure 5), where the carbon released from the coating forms in humid environments an easy shearable, a few nanometer thick reaction layer characterized by weak C-H bonds (Rebelo de Figueiredo et al, 2010). In particular, TiC x N 1Àx is also of interest because of its excellent friction properties, where the friction coefficient of TiN in the order of 0.6-0.8 (Fateh, Fontalvo, Gassner, & Mitterer, 2007;Franklin & Beuger, 1992) against alumina is reduced to approximately 0.2 due to the formation of the TiC x N 1Àx solid solution (Rebelo de Figueiredo et al, 2008).…”

“…Coefficient of friction and transfer film thickness formed on a TiC x N 1Àx coating plotted versus the number of cycles for a reciprocating sliding test against an Al 2 O 3 counterbody performed in an atmosphere with 35-45% relative humidity (Rebelo deFigueiredo et al, 2010).…”

“…It is also possible that a major fraction of the counterpart wear occurred prior to the formation of the transfer film. In order to study the transfer Lines are a guide for the eye film formation in detail, in situ characterisation methods that monitor the tribological contact during sliding need to be used [25].…”
