Characterization of the rouging in laboratory

You want to characterize rouging on your materials?

What is rouging?

Rouging is a very thin film that appears as a result of a disturbance of the outer layer of the surface of stainless steels. The formation of iron oxides and other metal oxides is thus favored and leads to the coloration of the surface. 

Rouging is characterized in particular by a coloration of the surfaces of certain stainless steel equipment, from yellow to black, through orange and red, depending on the extent of the phenomenon.

Why characterize the rouging on your materials?

Rouging is not a spontaneous phenomenon. In fact, the appearance of rouging is characteristic of a failure generally linked to the surface treatment. It also implies that the steel loses its anti-corrosion properties and its resistance.

Thus, the characterization of rouging by a specialized laboratory is essential in the optimization of your materials.

FILAB supports you in the characterization of rouging on your materials

Through our three levels of services: analysis, expertise and R&D support, FILAB assists companies of all sectors and sizes. 

Indeed, FILAB supports you in the characterization of rouging and takes charge of the different steps of realization.

Thanks to its high level of in-house expertise and diversified analytical resources, FILAB can offer you solutions tailored to your needs. Thus, our laboratory provides you with several analytical techniques:

Time-of-flight Secondary Ion Mass Spectrometry (TOF-SIMS). This method allows, to begin with, to obtain elementary and molecular information on the species present on the extreme surface of samples
X-ray photoelectron spectroscopy (XPS/ESCA). This method allows then to determine the elemental chemical composition of a material on a depth of a few nanometers.
Scanning Electron Microscopy (SEM/EDX). Finally, this method allows morphological observations and local semi-quantitative chemical analysis on the product
