| dc.description.abstract | In the present study, we prepared the FeCrAlTiY-10 mass% MoSi2 coating on low carbon steel using the
spark plasma sintering (SPS) technique. Its resistance against oxidation and corrosion was studied in air and
atmosphere containing 20 mass% NaCl at 700oC for 8 cycles. The results show that a dense coating layer is
composed by FeCr containing Al and MoSi2 phases. After high temperature oxidation test, a thin protective Al2O3
layer was formed. While mix oxide scales composing of (Cr,Fe)2O3, Al2O3, and Fe3O4 were formed after high
temperature corrosion test. Althought, the affected area after corrosion test was more severe than after oxidation test,
the corroded sample somehow had a lower mass gain compared to oxidized sample after 8 cycles exposure. This
could be related to the effect of chlorine ions and oxide spallation during cyclic corrosion test. | en_US |
