Publikováno v: Detriche, S, Vivegnis, S, Vanhumbeeck, J-F, Felten, A, Louette, P, Renner, F, DELHALLE, J & Mekhalif, Z 2020, ' XPS fast depth profile of the native oxide layers on AISI 304, 316 and 430 commercial stainless steels and their evolution with time ', Journal of Electron Spectroscopy and Related Phenomena, vol. 243, 146970, pp. 146970 . https://doi.org/10.1016/j.elspec.2020.146970
The thin oxide layers forming on the metal surfaces of metals determine their interactions with the environment and have a strong influence on the materials properties such as corrosion resistance. Such oxide layers typically have a thickness in the

Effect of variation in oxygen concentration in static Pb–Bi eutectic on long-term corrosion performance of Al-alloyed austenitic steels at 500 °C
Autor: Serguei Gavrilov, Wouter Van Renterghem, Pierre Louette, Erich Stergar, Stéphane Lucas, Valentyn Tsisar
Publikováno v: Corrosion Science
Aluminium-alloyed austenitic steels Fe-14Cr-2Mn-20Ni-0.5Cu-3Al and Fe-14Cr-5Mn-12Ni-3Cu-2.5Al were tested at 500 °C in static Pb-Bi eutectic for 10,000 h. The concentration of oxygen in the liquid metal was changed in a controlled way over the cours

Publikováno v: Materials Today Proceedings. 4(4):4987-4997
Porous photonic structures found in several living organisms are known to display colour changes induced upon contact with liquids, vapours and gases. Usually these changes are due to physico-chemical phenomena such as the swelling of the structure e
