Oxidation Resistance of Coated and Uncoated SiC-Based Refractories
The potentialities of ceramic coatings as a protective layer have been discussed by the comparison of the oxidation kinetics between coated and uncoated SiC-based materials. It was observed that a thermally sprayed coating of titanium dioxide (TiO2), in the same conditions of oxidation, decreases the kinetics constants and acts as a diffusion barrier. The evolution of the (micro-)structural features of oxidized materials were followed by XRD and SEM.
