Abstract
The high-temperature corrosion (700–1000°C) kinetics and processes in sulfur vapor and hydrogen sulfide were investigated for ferritic steels containing Cr and Al. Observation and analysis of the reaction curves obtained allowed the various corrosion steps to be clarified. Formation of compact, protective layers, at either the alloy-sulfide or at the sulfide-gas interface, occurred in the early stages of reaction and subsequently, most of the layers formed were microcrystalline and porous. The influence of the system parameters, i.e., temperature, pressure of the sulfidizing agent, and alloy composition, is reported in this paper.
