| 제목 | Laser Surface Texturing on Cast Iron for Improving Tribological Properties |
| 초록 | Tribological properties of the applications are most important for saving energy or increasing serviceability in automotive industry. It is known that tribological behavior is strongly related to the topography between each surface. Recently, Laser surface texturing of tribological applications is one of most important candidate for saving energy technology. In this research, Yb fiber laser (λ=1064nm) was used to generate different structures on Cast Iron surface. microdimpes were generated on the flat surface by a laser ablation process. Textural features such as size, density of micro dimples and orientation could be modified easily changing the laser parameters due to the flexibility of the laser system. The effect of different topographies on tribological behavior was examined by using ball-on-disk tribometer in commercial engine oil. Laser textured Cast Iron surfaces mated to Steel ball showed that a reduction of friction could be achieved in comparison to the polished surfaces. |
