| Summary: | Laser micro texturing technique has shown its potential in reducing friction and wear at various mechanical interfaces
such as automotive and cutting tools etc. Automotive parts are coated with Diamond-like Carbon (DLC) coatings to
enhance their performance. Due to stringent condition at the automotive contacts and demand for performance
enhancement, increase in performance of DLC coatings is required. In this study laser micro texturing is being
combined with tungsten doped DLC coating. In order to analyze the benefits of laser micro texturing on tungsten
doped DLC coating. Tribological testing was conducted on a reciprocating test rig at various loading conditions. The
results indicated that laser textured tungsten doped DLC coating showed the lower coefficient of friction compared to
un-textured tungsten doped DLC coating at a load of 15 N, 25 N and 35 N. Higher graphitization was observed in the
case of un-textured coating at 35 N load. |
