The surface of a material is a vulnerable zone where many interactions with its environment take place. It conditions, by its specific characteristics, the global performances of materials. It can impact the reliability and the solidity of a product in case of failures (corrosion, wear, adhesion, friction…).
Moreover, whatever its manufacturing process, the surface is not perfectly smooth. Indeed, this can depend on various factors such as: the machining method, the tools used, the materials. These materials have many irregularities that can be called defects. All these surface defects constitute the roughness.
Shape : Deviations over long periods or non-cyclic deviations
Ripples: Surface structure with longer intervals of irregularities.
Roughness : Irregularities with short intervals
Why is surface roughness important?
Each production process has an impact on the quality of the surface and thus leads to the appearance of roughness. In this context, the FILAB Laboratory supports you in your surface roughness issues through the following services:
