Thermal Barrier Coatings (TBCs) are used extensively to protect components of gas turbines or diesel engines against deterioration at high temperatures, oxidation and corrosion attack by reactive species, especially sulfurs. A TBC can be manufactured by implementing atmospheric plasma spraying (APS)
During high temperature operation, the thermally grown oxide (TGO) usually forms along the bondcoat/topcoat interface in thermal barrier coating (TBC) and was characterized as a driving force for the failure of the coating system. The effects of TGO thickness and Al 2 O 3 interlayer applied as an ox
The general role played by thermal and residual (TR) stresses in fracture mechanics is still unclear. It is sometimes argued (a) that in the linear elastic fracture mechanics (LEFM) regime TR stresses are secondary (rather than primary) i.e. that the overall loading is relaxed (rather than maintaine
