Effect of laser-glazed treatment on thermal cyclic behavior of plasma-sprayed Lanthanum Zirconate/Yttria-stabilized Zirconia double ceramic layered on NiCoCrAlYTa-coated Inconel

This paper investigates the thermal barrier coating (TBC) performance of La2Zr2O7/ZrO (2-8 wt.%) Y2O3 coatings (LZ/YSZ TBCs) deposited using atmospheric plasma spray (APS) over high velocity oxy-fuel (HVOF) NiCoCrAlYTa coated on Inconel 625. On the outermost surface of the double-layered coating, a...
