What we offer?

Bilasurf offers new methods for surface functionalisation of complex 3D parts using a laser-based high-rate process. The manufacturing path to develop those methods includes innovation in the following areas: design and simulation of bio-inspired functional surfaces, precision laser tooling, manufacturing integration, inline monitoring and new manufacturing guidance.

These methods serve to create nano- and micro-structured surfaces based on designs inspired by nature, mimicking shark skin (so-called riblet surfaces) and reducing the frictional resistance of flat surfaces. This effect is notably higher for 3D streamlines bodies (e.g. airfoils), as it also positively affects flow separation. 

By varying the size and shape of the riblets, different effects can be achieved on the textured surface. As the friction often accounts for an important part of energy consumption, a technology to allow these riblet designs to extend to additional applications and sectors is a key to aim for a more energy-efficient industry.

In order to avoid the actual setbacks, BILASURF proposes a new functionalising process for complex 3D shaped parts which suppose a benefit regarding the traditional processes carried on.

Traditional processes​

Generation of unwanted by-products: Due to their very nature, these processes thereby leave a significant environmental footprint. 

Chemical reactions: the creation of functional surfaces has traditionally relied on processes with a lot of chemicals.

Complete coating of the native surfaces (e.g. aerofoils).

Complex design and application of riblets on highly rotating parts (fan wheels or hydro turbines): the commonly used adhesive foils including the riblet coating cannot meet this requirement.
