? 2022 Elsevier B.V.Novel thermal barrier coatings (TBCs) based on Mg2SiO4/8YSZ double-ceramic-layer (DCL) were prepared by atmospheric plasma spraying (APS). Thermal cycling tests of the TBC specimens were performed at 1373 K. Results indicate that the DCL coating has a much longer lifetime compared to the single layer Mg2SiO4 coating. This is attributed to the fact that DCL Mg2SiO4/8YSZ TBCs further enhances the thermal insulation effect, improves sintering resistance and relieves thermal mismatch between ceramic layer and bond coat (BC). It can be concluded that this DCL coating structure design is ideal to optimize the performance of single layer Mg2SiO4 TBC and shows the Mg2SiO4 exhibiting a promising potential as new TBC materials.
