Finite Element Analysis of Wrap up Coating Material on Gas Turbine Blade

The wrap up coating material is used to safeguard the gas turbine blade from elevated temperature and soaring pressure gas, rust, wearing away and mechanical wear. The base material which is used for blade might diminish its functional life while in functioning in rigorous scorching burning gases. The scorching burning gas may possibly to cause and to raise the thermal stresses and unusual deformation. In this perspective work, the deformation and von-misses stresses are estimated for base material and diverse wrap up material with acceptable thickness useful on base material. The gas turbine blade base material is Hardenable nickel-chromium base cast alloy, and its wrap up material is lanthanum Hexaluminate. The deformation and von-misses stresses are estimated for without-coated hardenable nickel-chromium base cast alloy and 0.6 mm thickness coated of lanthanum Hexaluminate material. The Finite element method (FEM) is used to estimate the deformation and von-misses stresses for without-coated and diverse coating materials with 0.6 mm thickness. The evaluation is carried out for without -coating and for diverse coating materials in terms of deformation and von-misses stresses in lowest and highest temperature range.
