Thermal barrier coating (TBC) usually is deposited on nickel-based superalloy substrates for high temperature applications. In this study however, TBC is deposited on medium carbon steel with two different topcoat material which are the 8 wt% yttria stabilized zirconia (8YSZ) and the mullite using an air plasma spraying (APS) method. The aim is to reduce the heat transfer in its application as thermal barriers in electrical turbocompounding systems. The microstructure and thermal cycle life of the as-sprayed TBC are investigated. From the SEM image, the 8YSZ and mullite coating is uniformly deposited on a medium carbon steel substrate. The lifetime of 8YSZ coating is higher than of the mullite coating at 64 cycles for the 8YSZ coating and 14 cycles for the mullite coating. Consequently, in using medium carbon steel as a substrate, the applicable topcoat material for TBC application is the 8YSZ rather than the mullite in terms of better thermal cycle life.
