Thermal Conductivity of a Zirconia Thermal Barrier Coating
The conductivity of a thermal-barrier coating composed of atmospheric plasma sprayed 8 mass percent yttria partially stabilized zirconia has been measured. This coating was sprayed on a substrate of 410 stainless steel. An absolute, steady-state measurement method was used to measure thermal conductivity from 400 to 800 K. The thermal conductivity of the coating is 0.62 W/(m⋅K). This measuremen...

cement is an essential ingredient in the concrete buildings. for production of cement considerable amount of fossil fuel and electrical energy is consumed. on the other hand for generating one tone of portland cement, nearly one ton of carbon dioxide is released. it shows that 7 percent of the total released carbon dioxide in the world relates to the cement industry. considering ecological issu...
Evaluation of thermal conduction anisotropy on Thermal Barrier Coating
The microstructural analysis of Thermal Barrier Coatings, deposited according to the Air Plasma Spray technology, furnishes information according which a strong orthotropic thermal conductivity is expected to be measured for such a material. Pulsed experiment with a localized heating source and thermographic temperature recording, permit to evaluate both the in-depth and in-plane components of ...
