An original concept for the synthesis of an oxide coating: The film boiling process

The film boiling chemical vapor process is an original and rapid synthesis method for ceramic coatings composites. This work reports the deposition of silica coating from tetraethyl orthosilicate (TEOS) by process. Experiments were carried out under atmospheric pressure between 900 °C 1100 °C. Several modifications experimental setup made in order to allow a better thermal monitoring. Silica fast synthetized: several microns per minute. An activation energy 209 kJ/mol ± 20 was deduced. structure microstructure oxide characterized Optical Microscopy, Scanning Electron Energy Dispersive Spectroscopy, Probe MicroAnalyzer, Fourier-Transform InfraRed spectrometery X-ray diffraction.
