“…At high annealing temperature of more than 673 K, the enhanced mobility of atoms may cause the relaxation of compressive stress in the films and the desorption of hydrogen atoms from the Fig.11 Results of the Raman spectra after annealing films, thus inducing an increase of the order of sp 2 -bonded clusters, i.e., graphitization. As a result of the graphitization, the D and G peak curves tend to be separated as distinct peaks are indicative of the more graphite materials [18][19][20] . The presence of the separated D and G peaks shown in Figs.…”

In order to estimate the wear process of diamond-like carbon (DLC) films, a ball on disk test and a micro laser Raman spectroscopy are employed in this study. DLC films are deposited on high-speed tool steel (JIS-SKH51) surfaces by a plasma based ion implantation and deposition (PBII&D). After the ball on disk test with a steel ball (JIS-SUJ2) as an indenter, a mapping measurement using micro laser Raman spectroscopy has been accomplished against both the wear surface of the DLC films and the surface of the indenter. As a result, obvious changes in the structure of the DLC films originating from the contact interface between the substrate and the indenter are observed. This is like to be caused by the graphitization of the DLC films. On the other hand, except for the preceding descriptions, the Raman spectra are almost same to each other and there are no changes in the structure of the DLC films. This means that the effects of the sliding on the changes in the structure can be neglected. In addition, the carbon compounds and the solid solutions of carbon and iron included in the substrate and the indenter hardly influence the Raman spectra with or without sliding.

“…Consequently, the opportunity to rebuild the temperature field on the outermost surface is a key factor for determining the friction factor value. A recent experimental study of Sutter and Ranc [7] showed that friction between two samples of medium-low carbon steel at 34 m/s can induce flash temperatures over 1100 C. Bogdanovich and Tkachouk [8] showed that temperature reached between two asperities can attain the melting point of the softer material. They were pioneered by Block [9] who has first highlighted the flash temperature concept.…”

“…Chen and Li, 2005 established a wear model to simulate the sliding processes to analyze the frictional heating. Bogdanovich and Tkachuk, 2006 presented some experiments to understand thermal phenomena in a sliding contact, revealing that asperities in contact were found to undergo the pulse effect of the temperature approaching the melting point of one of the friction members. But few research works are focused on prediction theory of fusion micro-zone of the realistic engineering surface which was constructed by a set of patches whose sizes and shapes are irregular.…”

Purpose -The purpose of this manuscript is to analyze the fusion micro-zone generated by typical rough surfaces and investigate the factors of thermal effects on the tribological performance of surface asperities and its results verified by the experiment. Design/methodology/approach -A three-dimensional fractal rough surfaces sliding contact model has been developed, which takes into account temperature rise and distribution. The finite-element method, Green's function method, thermal conduct theory and contact mechanics are used as the solution methods. Findings -The results yield insights into the effects of the sliding velocity, thermal properties of the material, normal load and surface roughness on the temperature rise of the sliding contact surface. It allows the specification of working conductions' properties to reduce fusion. Originality/value -The model is developed and described by using the features of the contact between one flat surface and one rough surface with varied topographies. It can be easily applied for solving the sliding contact problems with different working conditions and specified for designing the surface accuracy in the severe working condition.
