“…These conditions determine that the development of a new thin film sensor must take into consideration sensor durability and sensing material stability in order to withstand these harsh environment and to meet expected service lifetimes that range between 10,000 h (for civil aeroengine applications) and 100,000 h (for industrial/power generation applications) [9,10]. One of the elements critical in ensuring sensor durability is the bond coating composition, which influences the oxide formation on that bond coat.…”

“…S ilicon‐based ceramic matrix composites are considered as promising structural materials for high‐temperature applications due to their high‐temperature mechanical properties and excellent oxidation resistance in dry air 1–6 . However, when exposed to combustion environments containing water vapor, silicon‐based ceramics were oxidized and corroded due to volatilization of gaseous silica hydroxide species formed by the following reaction between the formed silica and water vapor, as indicated in previous studies 7–12 : …”

The corrosion behavior of scandium silicates with different scandia contents were investigated in an atmosphere of 50%H 2 O-50%O 2 water vapor with a total pressure of 1 atm at 14001C. The weight changes of scandium silicates as a function of annealing time were recorded to illustrate the corrosion behavior of these materials. The phases of as-prepared and corroded materials were compared by using X-ray diffraction and Fourier transform infrared spectroscopy. The results indicate that the water vapor does not corrode the scandium disilicate. The weight gain during corrosion is attributed to the hydroxylation of free scandia.

For many applications the weathered surface is satisfactory, but anodising is often undertaken, particularly for architectural items, to preserve a smooth appearance, but periodic washing is desirable, especially when the anodic film is coloured.…”
