摘要

The present work describes investigations on the transformation behavior of the intermetallic phase (Fe, Cr)(2)Al-5 which forms on martensitic 10%Cr steel during aluminizing. In order to improve the mechanical properties of the coating and to incorporate the metallic Al overlayer, a subsequent heat treatment is necessary after aluminizing. Heat treatments were carried out in Ar at 700 degrees C and 1075 degrees C for several exposure times. It was found at 700 degrees C that the (Fe, Cr)(2)Al-5 scale starts to transform into the softer (Fe, Cr)Al phase (referring to hardness) at the scale-substrate interface. This process is time dependent. The (Fe, Cr)Al phase gets further transformed into the alpha-Fe(Cr, Al) solid solution. After heat treatment at 1075 degrees C for 0.5 h the (Fe, Cr)(2)Al-5 scale is completely transformed. The resulting scale can be subdivided into an upper layer of (Fe, Cr)Al phase, an intermediate band of pores and a lower layer of alpha-Fe(Al, Cr) solid solution. (C) 1997 Elsevier Science B.V.
