Abstract
Abstract In this research work, aluminium oxide/yttria stabilized zirconia (20%Al2O3/80%8YSZ) and ceria/yttria stabilized zirconia (20%CeO2/80%8YSZ) were coated through atmospheric plasma spray technique (APS) as thermal barrier coating (TBC) over CoNiCrAlY bond coat on aluminium alloy (Al-13%Si) substrate piston crown material and their thermal cycling behavior were studied experimentally. Thermal cycle test of both samples were conducted at 800 °C. Microstructural, phase and elemental analysis of the TBC coatings were experimentally investigated. The performance, combustion and emission characteristics of Al2O3/8YSZ, CeO2/8YSZ TBC coated and uncoated standard diesel engine were experimentally investigated. The test results revealed that CeO2/8YSZ based TBC has an excellent thermal cycling behavior in comparison to the Al2O3/8YSZ based TBC. The spallation of the Al2O3/8YSZ TBC occurred mainly due to the formation of thermally grown oxide (TGO), and growth of residual stresses at top coating and bond coating interface. The experimental results also revealed that the increase of brake thermal efficiency and reduction of specific fuel consumption for both TBC coated engine. Further reduction of HC, CO and smoke and increase of NOx emission were recorded for both TBC coated engine compared to the standard diesel engine.
