Direct Laser Interference Systems for the Surface Functionalization of Powertrain Components
Periodic patterned surfaces do not only provide unique properties, but act as intelligent surfaces
capable of selectively determine various functionalities in applications, such as biomaterials, surface
engineering, photonics and sensor systems. In particular, these surfaces have demonstrated control of friction
and wear in both lubricated and non-lubricated conditions.
In this paper, we introduce a recently developed approach for the fabrication of two and three dimensional
structures using Direct Laser Interference Patterning (DLIP). The fabricated structures range from the submicrometer to micrometer scale, and were directly fabricated on metals as well as on diamond like carbon
coatings. Different examples of fabricated arrays and their applications in tribology are discussed.
