    Korozní odolnost slitin na bázi Fe3Al ve vybraných sklovinách
    (Technická Univerzita v Liberci, 2010-01-01) Boháček, Jan; Hotař, Adam
    The task of this thesis was determined the corrosion resistance of alloys based Fe3Al (Fe3Al Fe-25.41Al-5.23Cr, Fe-31.5Al-3.11Cr-0.005Ce, Fe-29Al-1.4Ti-0.31B, Fe-28.06Al-2.85Cr-0.53Zr) and chromium nickel steel in selected glasses. Tests were carried out in leaded crystal and opal glass. The resistance of all materials was investigated at 1200° C and the time interval 13-96 hours. A result of this work is a graphical representation of the weight increases / decreases of intermetallics and chromium nickel steel ČSN 417 255. Coloring of glass and surface roughness of the samples where also evalvated after 96 hours of corrosion test. The roughness of a samples, which was established statistical tools and compass dimensions, was compared with the initial state (before corrosion tests).
