Residual Stresses of Eb-pvd Thermal Barrier Coatings Exposed to High Temperature
The substrate material was nickel-based superalloy (In738LC), and CoNiCrAlY was pressureless plasma-sprayed on the substrate as the bond coating. As the top coating, zirconia with 4 mol% yttria was electron beam-physical vapor deposited (EB-PVD) on the rotating substrate. The rotation speeds in the EB-PVD process were 5, 10 and 20rpm. The specimens were exposed to 1273K in air atmosphere for 20...
متن کاملSimulation of the effect of sub- micron interface roughness on the stress distribution in functionally graded thermal barrier coatings (FG- TBC)
In this research, a numerical modeling was utilized to calculate the stresses caused during thermal cycling in a functionally graded thermal barrier coating (FG - TBC). The temperature – dependent material response of this protective material was taken into account and the effects of thermal cycle and interface morphology of the ceramic / metallic layer in functionally graded coating system wa...
متن کاملThree-dimensional Analysis of Transient Thermal Stresses in Functionally Graded Plates
An analytical solution is presented for three-dimensional thermomechanical deformations of a simply supported functionally graded (FG) rectangular plate subjected to time-dependent thermal loads on its top and/or bottom surfaces. Material properties are taken to be analytical functions of the thickness coordinate. The uncoupled quasistatic linear thermoelasticity theory is adopted in which the ...
متن کاملTransient Thermal Stresses of Functionally Graded Thick Hollow Cylinder under the Green-Lindsay Model
The transient thermoelastic response of thick hollow cylinder made of functionally graded material under thermal loading is studied. The generalized coupled thermoelasticity based on the Green-Lindsay model is used. The thermal and mechanical properties of the functionally graded material are assumed to be varied in the radial direction according to a power law variation as a function of the vo...
متن کاملThermal Buckling of Functionally Graded Beams
In this article, thermal stability of beams made of functionally graded material (FGM) is considered. The derivations of equations are based on the one-dimensional theory of elasticity. The material properties vary continuously through the thickness direction. Tanigawa's model for the variation of Poisson's ratio, the modulus of shear stress, and the coefcient of thermal expansion is considered...
