Design of ZrO<sub>2</sub>/Ti Functionally Graded Thermal Barreir Coatings Based on a Nonlinear Micromechanical Approarch
説明
<jats:p>This study presents a design process of ZrO2/Ti functionally graded thermal barrier coatings (FG TBCs) based on a mean-field nonlinear micromechanical approach developed by Tsukamoto [1], which takes into account the time-independent and dependent inelastic deformation, such as plasticity of metals, creep of metals and ceramics, and diffusional mass flow at the ceramic/metal interface. The effect of compositional gradations on micro-stress states in the FG TBCs has been examined. The suitable compositional gradations have been proposed for typical thermo-mechanical boundary conditions in terms of thermal-stress relaxations, thermal-shielding and light-weight characteristics.</jats:p>
