ResumenThe high temperature oxidation-sulfidation behavior of Cr-Al2O3 and Nb-Al2O3 composites prepared by mechanical alloying (MA) and spark plasma sintering (SPS) has been studied. These composite powders have a particular metal-ceramic interpenetrating network and excellent mechanical properties. Oxidation-sulfidation tests were carried out at 900 degrees C, in a 2.5\%SO2 + 3.6\%O-2 + N-2(balance) atmosphere for 48 h. The results revealed the influence of the sintering conditions on the specimens corrosion resistance, i.e. the Cr-Al2O3 and Nb-Al2O3 composite sintered at 1310 degrees C/4 min showed better corrosion resistance (lower weight gains) compared with those found for the 1440 degrees C/5 min conditions. For the former composite, a protective Cr2O3 layer immediately forms upon heating, whereas for the later pest disintegration was noted. Thus, under the same sintering conditions the Nb-Al2O3 composites showed the highest weight gains. The oxidation products were investigated by X-ray diffraction, scanning electron microscopy, and transmission electron microscopy. (C) 2007 Elsevier B.V. All rights reserved.es_ES
