Alumina deposited by metal-organic chemical vapour deposition process on NiCoCrAlYTa superalloy
Alumina deposit was produced by metalorganic chemical vapour deposition process on a NiCoCrAlY superalloy substrate. Low frequency injection in the range 5–10 Hz was used to feed the Aluminium Tri-isopropoxide precursor into a deposit chamber holding at 400 °C of temperature. Both scanning electron...

| description | Alumina deposit was produced by metalorganic chemical vapour deposition process on a NiCoCrAlY superalloy substrate. Low frequency injection in the range 5–10 Hz was used to feed the Aluminium Tri-isopropoxide precursor into a deposit chamber holding at 400 °C of temperature. Both scanning electron microscopy and X-ray diffraction analysis were accomplished to characterize the deposited alumina. Topographic images show an alumina deposit roughness of Ra 35 nm measured by atomic force microscopy. An X-photon spectroscopy analysis of the alumina deposit was performed to identify both Al species and chemical analysis. Thermo-gravimetric analysis was conducted to assess the effect of deposited alumina on the superalloy. |
