| 英文摘要 | MCrAl (M=Ni, Co, or their combinations) coatings have been widely used as high temperature oxidation protection coatings on turbine blades, as they can thermally grow stable, dense and well adherent Al2O3 protective scales. Due to the particulate nature of the exhaust,MCrAl coatings often fail owing to severe high-temperature wear. To improve the anti-wear resistance of the MCrAl coatings, NiCrAlSiC composite coatings were designed and fabricated by the combination of electrophoretic deposition (EPD) and electrodeposition (ED). The compositions, morphologies and structures of the as-deposited composite coatings were characterized by XRD, SEM, EPMA and TEM. A Ni7.4Cr6.2Al14.3SiC (mass fraction, %) coating, as well as a contrast SiC-free Ni7.2Cr6.2Al coating, was prepared. No cracks or micro pores were found either at the coating/substrate interface or in the coating, and elements distributed uniformly in the coating. Compared to the SiC-free coating, oxide scale on the NiCrAlSiC coating transformed from a three-layered structure (NiO, NiAl2O4 and Al2O3) to a thinner two-layered structure (NiAl2O4 and Al2O3), showing better high temperature oxidation resistance. And microhardness of the NiCrAlSiC coating increased 26%, together with the wear rate reduced 52%. Wear mechanism of the NiCrAl coating was abrasive wear, while that of the NiCrAlSiC coating switched to adhesive wear. These results indicate that the addition of SiC improves both high temperature oxidation resistance and wear resistance of the NiCrAl composite coating obviously. |
