  • Effect of Oxidation on Interfacial Fracture Toughness in Suspension Plasma Sprayed Thermal Barrier Coating

抄録

<p>In this study, Suspension Plasma Spraying (SPS) and Atmospheric Plasma Spraying (APS) thermal barrier coatings were used. After solid solution treatment, heat exposure tests were conducted at a temperature of 1000 ° C for a holding time of up to 1000h. The oxide layer (TGO layer) morphology, residual stress, In oxide layer (TGO layer) and interfacial fracture toughness were investigated. It was confirmed that the structure of the top coat layer of the SPS test piece has a crack suppressing effect. In addition, it was confirmed that, the residual stress and the interfacial fracture toughness decreased in the SPS test piece with an increase in exposure time.</p>
