OXIDATION OF Fe AND STEELS AT HIGH TEMPERATURES
Kučera, Jaroslav ; Adamaszek, K. ; Hajduga, M.
The results of surface oxidation and decarburization of (Fe, C, Mn, Si, Cr, Ni) steels are reported. The oxidation anneals were carried out at temperatures T = 940, 980, 1020, 1060, 1100 °C. The time course of Fe and of steels oxidation is expressed by parabolic law l = kp . The surface oxidation is accompanied by decarburization of surface steel layers. The evaluation of measured carbon concentration profiles N(C,x,t) yields diffusion coefficients D(C,T). Oxidation coefficients kp(T) are linearly proportional to D(C,T).
