Thermal Analysis of Functional Gradient Materials as Thermal Barrier Coating of Piston 2008-01-2754

It was simulated the temperature and thermal stress distributions of ceramics/metal functional gradient piston coating based on the third type boundary conditions of piston in IC engine under stable working conditions using the indirect solution method of thermal analysis and subsequently structural analysis by means of ANSYS10.0 finite element software. It was studied the effect of gradient composition distribution index p on the temperature of piston head and the thermal stress at the gradient layers of ceramics/metal. The optimal design result, as the gradient composition distribution index p = 0.6, could be obtained to relax the thermal stress.
