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.
