  • Protective metal oxide films on metal or alloy substrate surfaces susceptible to coking, corrosion or catalytic activity
    Patent number: 4297150
    Abstract: This case relates to a process for forming protective metal oxide films on metal or alloy substrate surfaces susceptible to coking, corrosion or catalytic activity. The process comprises first preoxidizing the substrate surface and then depositing on the pre-oxidized surface a metal oxide of Ca, Mg, Al, Ga, Ti, Zr, Hf, Ta, Nb or Cr by vapor phase decomposition of a volatile compound of the metal which has at least one metal-oxygen bond. Nitrogen, helium, argon, carbon dioxide, air or steam may be used as carrier gases for the metal compound.
