摘要：

Five ferritic stainless steels are characterized in terms of thermally grown oxide films and corrosion performance under simulated exhaust gas condensate conditions. Oxide films developed at 300 degrees C show only little variation in microstructure and properties between the alloys, whereas those evolved at 600 degrees C exhibit clear differences. Especially in alloys with >11.5 wt.% chromium, the presence and distribution of such alloying elements as titanium, silicon, niobium and molybdenum are crucial for the film properties and the overall corrosion performance. The results may be exploited in the compositional optimization of the alloys for the cold-end components of automotive exhaust system. (C) 2014 Elsevier Ltd. All rights reserved.
