Modelling Thermal Conductivity of Porous Thermal Barrier Coatings [PDF]
Coatings, 2019 Thermal conductivity of porous thermal barrier coatings was evaluated using a newly developed five-phase model. It was demonstrated that porosities distributed in coating strongly affect thermal conductivity. The decisive reason for this change in thermal conductivity can be traced back to defect morphology and its orientation, depending on the coating
