Abstract: A new method, the rule of the mixture is developed for the determination of thermal conductivity (K), allied properties viz.density and the volume of the individual composite coating powders. Optimum coating thickness through steady-state thermal analysis of composite coating (Al2O3+ZrO2•5CaO) applied on cast iron surface is carried out. Also, the thermodynamic behaviour of TGO and bond coat were simulated. The thickness of the topcoat, TGO, and the bond coat was varied independently in the range of 0.1 to 0.04 mm. Results show that topcoat thickness doesn't have much influence on the heat transfer. However, TGO and the bond coat plays a crucial role in heat transfer study. Maximum heat resistance, 171.47 C observed at 1 mm TGO thickness, compared to 88.94 C in case of bond coat for the same coating thickness. It is also understood that 1 mm of optimal TGO thickness may be beneficial in the design of thermal barrier composite coating systems. © Published under licence by IOP Publishing Ltd.
