Metal-ceramic coatings have been widely used for industrial applications, mainly in the gas turbine and
diesel engine industries as thermal barrier coatings (TBCs). Conventional thermal barrier coatings consist
of a metallic bond coat and an insulating ceramic topcoat. Temperatures and temperature gradients
in the coating during plasma spraying play an important role on the final coating quality, especially the
temperature of the particles just hitting the substrate surface. In this work, metal-ceramic coatings were
applied on nickel-superalloy substrates. The temperatures of both the coating surface and substrate were
measured during spraying. The adhesion of the coatings was determined using ASTM C 633 and correlated
with the measured temperatures. Optical pyrometry and thermocouples were used to measure the
interfacial and substrate temperatures, respectively. Temperature was shown to have a significant influence
where lower interfacial temperatures were found to result in lower adhesion values.
