Evaluation of thermal conduction anisotropy on Thermal Barrier Coating
نویسندگان
چکیده
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 the conductivity tensor. The utilization of a gaussian shaped heating function permits to compare both the direct solution and the one obtained by a spatial Fourier Transform.

In this paper a functional graded material (FGM) thermal barrier coating (TBC) is prepared using Atmospheric Plasma Spraying (APS) method. The FGM layers were deposited by varying the feeding ratio of CYSZ/NiCrAlY and conventional CYSZ on a NiCrALY-coated Inconel 738 substrates. Hot corrosion behavior, bonding strength and the related failure mechanisms of a conventional TBC and a FGM TBC are i...
متن کاملThe Behavior of Temperature on Insulated(MgZrO3) Diesel Engine Piston With ANSYS
In an internal combustion engine, the heat energy approximately one third of total fuel input energy is converted to useful work. Since the exhaust gas temperature is not equal environmental temperature, so lot of heat energy lost with hot gases. Also heat energy is lost in cooling of engine. If we recovered heat energy which lost in cooling instead on crankshaft as useful work, then increase t...
