E. Caudron et H. Buscail, Comparison of the oxidation resistances of yttrium implanted low manganeseand low manganese-carbon steels at high temperature, APPL SURF S, 158(3-4), 2000, pp. 310-329
Yttrium implanted and unimplanted low manganese and low manganese-carbon st
eel samples were analyzed at T = 700 degrees C and under an oxygen partial
pressure P-O2 = 0.04 Pa for 24 h to show the yttrium implantation effect on
sample high temperature oxidation resistances. Sample oxidation weight gai
ns were studied by thermogravimetry and structural analyses were performed
by in-situ high temperature X-ray diffraction (XRD) with the same experimen
tal conditions. The aim of this paper is to show the initial nucleation sta
ge of the main compounds induced by oxidation at high temperature according
to the initial sample treatment (yttrium implanted or unimplanted). The re
sults obtained by in-situ high temperature XRD will be compared to those by
thermogravimetry to a better understanding of the weight gain curves obser
ved during the oxidation test at 700 degrees C and P-O2 = 0.04 Pa. This stu
dy allows us to show the improved corrosion resistance of yttrium implanted
low manganese and low manganese-carbon steel at high temperature. (C) 2000
