Title
Research Paper / Environment : Simultaneous Oxidation - Chloridation of Austenitic Stainless Steels by NaCl in Air
권종원Jong Won Kwon, 이윤용Yun Yong Lee, 이용득Yong Deuk Lee
Abstract
Simultaneous oxidation-chloridation behavior of austenitic stainless steels by NaCl in air was investigated at 650℃. Oxide scale formed on the surface of every test alloy consisted of inner spinel layer and outer Fe₂O₃ layer. Condensed and gaseous chlorides were formed at the alloy/scale interfaces by NaCl vapors which penetrated via pores or cracks of the scales. Phase equilibria and the partial pressures of gaseous species at the interfaces between alloys and product phases were calculated by computer-assisted thermodynamic calculations using the Thermo-Calc computer program. A mechanism was proposed for the overall oxidation process including the initial reaction of alloys with NaCl, the rapid formation and growth of oxide scales, and the transport of gaseous species through the oxide scales.
