“…A change in COF and wear behavior was observed with an irradiation from 2.5 × 10 14 to 6.5 × 10 15 cm -²s -1 . Fan et al [25] showed that Helium (He) ion irradiation leads to an increase in nano-hardness and a decrease in surface roughness. Using RAMAN, they observed a microstructural evolution to a structure containing a large fraction of sp2hybridized structure clusters.…”

Diamon-like carbon (DLC) coatings protect engine parts from wear and provide low-friction. Unfortunately, the nature of DLC coatings does not allow progressing wear measurement using conventional methods. Therefore, we applied a radioactive isotope-based wear measurement method (RIC method). A tribometer with oscillating contact and one with sliding contact were used to provide different loading conditions. The RIC method was evaluated for DLC coatings, and the DLC wear was investigated regarding the presence of abrasive particles. The results indicate that an increase in abrasive particle concentration leads to an increase of DLC wear rate and a decrease in usage-time until wear-off.
