dc.description.abstractThis study comparatively presents the thermal and mechanical effects of different Thermal Barrier Coatings (TBCs) and their thicknesses on the performance of aluminum diesel engine piston by combining Finite Element Analyses (FEA) and Artificial Neural Network (ANN) methods. The piston structure of MWM TbRHS 518S indirect injection six-cylinder diesel engine was modeled. The clustered TBCs (NiCrAlY-Gd2Zr2O7, NiCrAlY-MgO-ZrO2, NiCrAl-Yttria Partially Stabilized Zirconia (YPSZ), and NiCrAlY-La2Zr2O7) were implemented to the related surface of aluminum alloy piston and then static, thermal, and transient structural FEA were conducted for each model. Based on both of the temperature and equivalent stress distributions, NiCrAlY-Gd2Zr2O7 coated model displayed the best performance. Additionally, the effects of top coating thicknesses of TBCs were investigated in the range of 0.1-1.0 mm with 0.1 mm increments in FEAs. The thermally effective top coating thickness was predicted as 0.95 mm for the selected TBC using ANN method. Then the effects of coating thickness on frictional performance were revealed by generating transient structural FE models and utilizing stribeck diagram. The uncoated and 0.95 mm NiCrAlY-Gd2Zr2O7 coated models were adjusted as transient and the related crank angle - dependent in-cylinder combustion pressure data was implemented. The friction force was reduced by at least 15% in NiCrAlY-Gd2Zr2O7 coated model.en_US
