Ciro Sinagra of Laminazione Sottile, a large company based in San Marco Evangelista, in the province of Caserta, together with colleagues at the University of Naples, has carried out a research on the stratigraphic analysis (and nanometric over 200 μm of depth from the surface) on some characteristic elements of aluminium alloy, after a thorough examination of the two laminate surfaces, which are artificially shiny and matt, and having understood the reasons for their different corrosion resistance.
To do this, the researchers used very innovative
technologies of superficial analysis, such as pulsing radio frequency and “glow
discharge optical emission” spectrometry.
This technique (which we suggest especially for surface treatment of aluminum profiles’ coating) can truly represent a revolution in the technical and practical knowledge to help understand the difficult physical and chemical mechanisms that occur on the surface of extruded materials, which sometimes lead to disastrous defects such as peeling, exfoliation and more, invalidating all the window frames or all the curtain walls of a civil construction.
