Abstract

Synthesis and characterization of titanium and zirconium oxide and carbide thin films (1–25 μm) on spherical substrates is reported. Hydrolysis of an appropriate metal alkoxide precursor in aqueous acid yields the amorphous metal oxide coating. Thermal treatment can produce the highly crystalline phases of the oxides or, in the presence of a carbon containing reducing gas, the metal carbide. Scanning electron microscopy and x-ray diffraction have been used to study the surface morphology and the crystallographic structure of the coating films. Morphological characteristics strongly depend on the acid species and acid strength used during hydrolysis. The thickness of the film is also governed by control of the acid hydrolysis step.
