Abstract
Dimples with various pitches and densities were produced using laser surface texturing (LST) to improve the friction and wear behavior of graphite cast iron. The objective of this study is to investigate the effectiveness of dimples on the friction and wear behavior of an internal combustion engine (ICE) cylinder. The specimens with a dimple pitch of 150 μm and a dimple density of 13% exhibited the lowest friction coefficient among the specimens, while the specimens with a dimple pitch of 200 μm and a density of 7% exhibited the highest resistance to wear.
