摘要：

Al coated steel sheets are being used for heat resisting application such as muffler for automobile, fuel tank, microwave oven, and combustion chamber parts. These are commercially produced by hot-dip galvanizing process and their heat resisting properties are depending on their processes. In this study. Al coated steel sheets are fabricated by sputtering process in order to compare their properties with the ones of galvanizing. Hot-dip Al coated steel sheet (HACSS) showed a typical solidified structure of Al Si alloy: primary Al dendrite and Al Si eutectic structure. Intermetallic compounds were found between the coating layer and the steel substrate. On the other hand, sputtered Al coated steel sheet (SACSS) represented a well-mixed structure of Al Si. No intermetallics were observed. Heat resistance tests were carried out at 450 degrees C and 500 degrees C. HACSS was discolored at 450 degrees C, but SACSS at 500 degrees C. In this study, heat resistance experimental results are analyzed and discussed based on their microstructures of non-ferrous/ferrous metal hybrid system. (C) 2012 Elsevier B.V. All rights reserved.
