摘要：

An Fe-27 w/o (weight %) Mn alloy was sulfidized at temperatures of 973, 1073, and 1173 K inflowing H2/H2S/N2 atmospheres corresponding to equilibrium sulfur pressures of 8 Pa. Steady-state parabolic kinetics were always observed after an initial period during which the instantaneous parabolic rate constant increased with time. Product scales were compact and consisted of a layer of Fe(Mn)1-x S over an inner layer of α-Mn(Fe)S. Preoxidation led to a diminution in the subsequent sulfidation rate. Conflicts between differing reports in the literature of the kinetics of this reaction are resolved, and it is concluded that the protective effect expected of an α-MnS layer is in fact possible. © 1990 Plenum Publishing Corporation.
