Oxidation Corrosion Behavior of Composite Cladding of Intermetallic Compound Ni3Si

Abstract:

The oxidation resistance of Ni-Si-Ti-C, Ni-Si-C-Nb in-situ reinforcement clad layers has been investigated by cyclic oxidation tests at the temperature 1100°C. The oxidation performance were characterized by Thermo-gravimetric (TG),scanning electron microscopy (SEM) and X-ray diffractometer (XRD),the TG date indicates good oxidation resistant was reached for the clad layers. The kinetic constant Kp and the micrograph of oxidized samples shown that NbC reinforce clad layers which oxide products including NiO, SiO2 and Nb2O5 has better oxidation resistant than TiC reinforce clad layers which oxide products including NiO, some SiO2 and TiO2.
