Abstract

Thermal barrier coatings (TBC) were manufactured by thermal spraying of CoNiCrAlY and YSZ powders, which constituted the bond coat (BC) and top coat (TC), respectively. The BC was deposited on stainless steel substrates by a high velocity oxygen fuel (HVOF) systemwhilst the TC was deposited on the BC by an atmospheric plasma spraying (APS) gun. TBCs were heat treated at 1200 °C for 8 and 16 h in order to determine the evolution of the residual stress state as a function of time. The residual stress profiles were obtained by employing the Modified Layer Removal Method (MLRM) and an adaptation of this for bilayer coatings called Modified Layer Removal Method for Duplex Coatings (MLRMDC). It was observed that as the exposure time was increased, the compressive residual stresses increased, which was more noticeable in the BCs. The TBCs without heat treatment revealed tensile residual stresses.
