Paper Abstract

In this paper we will discuss various aspects of surface engineering. This is a broad term, and we choose to focus on two aspects thereof, namely surface texturing on the micron scale using laser micromachining, and chemical modification of the surface using molecular vapour deposition (MVD). First, we will discuss the basics of laser texturing, followed by a brief review of contact angle theory. We will then demonstrate how to obtain superhydrophobic surfaces on any kind of material using a combined laser and MVD process. Finally, we will present a few recent industrial cases.
