摘要：

High temperature and pressure produced in an internal combustion engine may lead to high thermal stresses. A piston may need to be coated to avoid fails operation due to insufficient heat transfer. Common material that used as a material for Thermal Barrier Coating (TBC) is Yttria Partially Stabilized Zirconia (YPSZ) and a ceramic based material called Mullite which has very good properties against high temperature application. In this work, the usage of Mullite and YPSZ were compared to improve the performance of TBC and were plasma sprayed on piston crown (AC8A aluminium alloys) in order to reduce thermal stresses. Those samples were deposited with NiCrAl bonding layers prior to coating of Mullite and YPSZ some samples is remained uncoated for comparison purpose. Detailed analyses (microstructure and hardness) on the deposited coating were examined and studied.
