The kinetic curves of the high-temperature oxidation of austenitic heat resistant stainless steel 1.4828 at1050℃ were measured using a weighing method.It is shown that the oxidation curves at 1050℃ followed the parabolic line law,and after 250 h of oxidation,the mass gain was about 80 g/m~2.The surface morphology and structure of the oxide layers were studied by scanning electron microscopy and X-ray diffraction.A complicated oxide layer obtained at 1 050 ℃ was mainly composed,from inner to outer,of(FeSi)_3O_4,Cr_2O_3,Fe_2O_3,and spinel oxides FeCr_2O_4 and NiMn_2O_4.
The kinetic curves of the high-temperature oxidation of austenitic heat resistant stainless steel 1.4828 at 1050 ° C were measured using a weighing method. It is shown that the oxidation curves at 1050 ° C followed the parabolic line law, and after 250 h of oxidation, the mass gain was about 80 g / m ~ 2. The surface morphology and structure of the oxide layers were studied by scanning electron microscopy and X-ray diffraction. A complicated oxide layer obtained at 1 050 ° C was mainly composed, from inner to outer, of (FeSi) _3O_4, Cr_2O_3, Fe_2O_3, and spinel oxides FeCr_2O_4 and NiMn_2O_4.
