Thin Fe/Cr films with lateral composition gradients were deposited by magnetron sputtering; the analysis of the films was done with microscopy and X-ray photoelectron spectroscopy (XPS). The local interfacial polymeric film formation could be therefore directly correlated with the Fe:Cr ratio. The local thickness and structure of the formed polycarbonate residue was analyzed by means of imaging ellipsometry, atomic force microscopy as well as Fourier-transform infrared spectroscopy under grazing incidence and XPS. Moreover, confocal fluorescence microscopy of the PC melt/alloy interface could reveal the formation of minor degradation products in the interphase region. The results show that already an Fe:Cr ratio of 2 : 1 leads to a strong inhibition of the thermal degradation in comparison to the unalloyed iron, and that in general, the enrichment of chromium in the passive film leads to an effective suppression of interfacial PC degradation. The data contributes to improving the mechanistic understanding of the role of iron during this process. Additionally, a critical concentration of chromium in the alloys used for PC processing can be deduced."}]},{"author":[{"first_name":"J.","last_name":"Varghese","full_name":"Varghese, J."},{"first_name":"P.","full_name":"Vieth, P.","last_name":"Vieth"},{"full_name":"Xie, X.","last_name":"Xie","first_name":"X."},{"id":"194","full_name":"Grundmeier, Guido","last_name":"Grundmeier","first_name":"Guido"}],"volume":5,"date_updated":"2022-12-21T09:29:01Z","doi":"10.1007/s42452-022-05244-0","publication_status":"published","publication_identifier":{"issn":["2523-3963","2523-3971"]},"citation":{"bibtex":"@article{Varghese_Vieth_Xie_Grundmeier_2022, title={Enhanced corrosion resistance of epoxy-films on ultra-thin SiOx PECVD film coated laser surface melted Al-alloys}, volume={5}, DOI={<a href=\"https://doi.org/10.1007/s42452-022-05244-0\">10.1007/s42452-022-05244-0</a>}, number={129}, journal={SN Applied Sciences}, publisher={Springer Science and Business Media LLC}, author={Varghese, J. and Vieth, P. and Xie, X. and Grundmeier, Guido}, year={2022} }","short":"J.

Laser surface melting (LSM) was performed using a continuous wave mode at a wavelength of 1064 nm. Ultra-thin plasma polymer films were deposited from a mixture of hexamethyldisilane (HMDSO), oxygen, and argon by means of an audio-frequency glow discharge. The surface morphology and surface chemistry compositions were investigated by employing field emission scanning electron microscopy, energy-dispersive X-ray spectroscopy (EDX), diffuse reflection infrared Fourier transform spectroscopy, and X-ray photoelectron spectroscopy. The corrosion resistance of plasma polymer coated LSM Al-7075 alloy was studied using linear sweep voltammetry and electrochemical impedance spectroscopy in a chloride-containing electrolyte. The electrochemical studies showed an improved corrosion resistance for plasma film-coated alloys compared to the just laser surface melted state. To study the corresponding surface adhesive properties, the samples were coated with an epoxy amine adhesive. 90°-peel test under humid conditions confirmed the improvement of interfacial wet-adhesion corrosion tests showed a strong improvement of the delamination resistance of adhesives caused by the ultra-thin interfacial SiO<jats:sub>x</jats:sub>-films.</jats:p>","lang":"eng"}]}]
