oxidation%metal%dynamic scanning electron microscope
A Dynamic Environmental Scanning Electron Microscope (DESEM) was developed in this laboratory for in situ monitoring of the morphology of metal surface during oxidation. The process of nucleation and growth of oxide grains/whiskers on Fe, Ni and TiAl during oxidation were successfully observed and recorded continuously by using our KYKY1500 ESEM. The experiments were carried out under different conditions of oxidation: temperature in the range of 500～750 ℃ and oxygen partial pressure in the range of 10-4～45 Pa. In the light of the observed surface morphology and microstructure during the oxidation, the growth mechanism and reaction kinetics were discussed.
