Summary
Ceramic oxide materials such as Al2O3, YAG, mullite… have proved high corrosion resistance at high temperature. So, we have investigated the deposition of different ceramic oxides thin films on carbon substrates whose utilization is limited below 600°C in air atmosphere in order to improve their corrosion resistance. Indeed, carbon undergoes oxidation reaction to form CO and CO2 inducing drastic weight loss, microstructural degradation and flexural strength decreasing. These damage indicators were recorded to follow the protection effect of deposited ceramic oxide films. The present paper reports the protection efficiency of silicon and aluminum oxides deposited by LF-PECVD and sol-gel process respectively.
