| Abstract: | Predicting “in-service” lifetime of ceramic thermal barrier coatings (TBCs) is difficult due to the inherent brittle nature
of ceramics used. Therefore, the study of metal-based thermal barrier coatings (MBTBCs) has been initiated to challenge the
current problems of ceramic-based TBCs (CBTBCs) and create a new generation of thermal barrier coatings (TBCs). In this work,
nano/amorphous structured MBTBCs, for use in internal combustion engines, have been produced using high frequency induction
plasma spraying (IPS) of iron-based nanostructured alloy powders. Coatings were deposited by IPS using various spray parameters
and heat treated up to 850 °C to study the thermal stability of the coating. The thermal diffusivity (α) properties of MBTBCs were measured using a laser flash method. Density (ρ) and specific heat (C
p
) of the MBTBCs were also measured for calculating thermal conductivity (k = αρC
p
).
