Ren, Y. He, D. Wang] A novel YSZ-YSZ/Al2O3 (YSZ means 6wt% yttria partially stabilized zirconia) double-layer thermal barrier coating was fabricated using composite sol-gel and pressure filtration microwave sintering (PFMS) technologies. In this double-layer coating, the top layer was YSZ ceramics with a thickness of about 150μm and the bottom layer was composed of micro-sized YSZ particles packed by nano-sized α-Al2O3 films and had a thickness of about 10μm. Cyclic oxidation tests indicated that this coating possessed superior properties to resist oxidation of alloy and spallation of coating. These beneficial effects could be mainly attributed to that, the alloy substrate could be sealed completely by α-Al2O3 phase and the thermal stress could be decreased by means of better thermal matching and nano/micron structure in YSZ/Al2O3 layer. Moreover, thermal insulation capability tests indicated that the thermal barrier effect was improved due to the application of YSZ/Al2O3 layer. YSZ/Al2O3 layer could be considered as a promising bond coat in TBCs.
