Analysis of rouging phenomenon in laboratory
Your needs: analyze the rouging phenomena on your products
What is rouging?
Rouging is a phenomenon that occurs when the outer layer of the surface of stainless steels is disturbed. The formation of iron oxides and other metallic oxides (nickel or chromium) is thus favored and leads to the coloration of the surface.
A very thin film, rouging is characterized 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 analyze the rouging phenomenon on your products?
Rouging does not occur spontaneously. In other words, rouging is a symptom of surface degradation of stainless steel. It also implies that the steel is losing its corrosion resistant properties and strength.
Furthermore, rouging is unstable and not an acceptable phenomenon in many processes. Indeed, the oxidation particles can detach and contaminate the possible transported products, which endangers the safety of the processes.
FILAB supports you in the analysis of rouging phenomena
Through our three levels of services: analysis, expertise and R&D support, FILAB assists companies of all sectors and sizes.
Indeed, FILAB accompanies you in the analysis of rouging phenomena and takes charge of the different stages of realization.
Thanks to its high level of in-house expertise and diversified analytical equipment, 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
