Variations in maximum temperatures of coating thickness for
coating, bond coat and substrate surfaces are shown in Fig. 8. The
maximum temperature of the coating surface increases with the
coating thickness by decreasing rate. The maximum temperature in
the bond coat and substrate surfaces reduces with the coating
thickness. There is no significant difference between the temperature
curves of substrate and bond coat material; they are almost
parallel with each other and the temperature difference between
them is less than 4 C. This temperature variation is similar to the
behavior of heat transfer in the substrate and bond coat.
