Spherical Gd_(2)Zr_(2)O_(7)hollow powders with a mean size of 8.8μm were fabricated as feedstock for thermal barrier coatings(TBCs)by *** single-ceramic-layer(SCL)Gd_(2)Zr_(2)O_(7)TBCs and double-ceramic-layer(DCL)Gd_(2)Zr_(2)O_(7)/YSZ TBCs with quasicolumnar structure were successfully fabricated by plasma spray-physical vapor deposition(PS-PVD).Tensile and water-quenching tests were applied to evaluate TBCs *** results show that adhesion strength of SCL Gd_(2)Zr_(2)O_(7)TBCs and DCL Gd_(2)Zr_(2)O_(7)/YSZ TBCs is36.5 MPa and 15.4 MPa,*** delamination of SCL Gd_(2)Zr_(2)O_(7)TBCs and DCL Gd_(2)Zr_(2)O_(7)/YSZ TBCs in the tensile test takes place at the middle and bottom of Gd_(2)Zr_(2)O_(7)layer,respectively,due to relatively lower fracture toughness of Gd_(2)Zr_(2)O_(7)*** 40 cycles of water-quenching test,DCL Gd_(2)Zr_(2)O_(7)/YSZ TBC surface keeps relatively intact,while SCL Gd_(2)Zr_(2)O_(7)TBC surface shows 20%visible destroyed regions,which demonstrates that DCL Gd_(2)Zr_(2)O_(7)/YSZ TBCs have a better thermal shock resistance than SCL Gd_(2)Zr_(2)O_(7)*** cracks in the SCL system propagate near thermally grown oxide(TGO)due to thermal mismatch and TGO growing stress,while cracks in the DCL system propagate in the Gd_(2)Zr_(2)O_(7)layer due to its relatively lower fracture toughness.

7 YSZ coating was prepared by plasma sprayphysical vapor deposition(PS-PVD) technique based on a specific experimental *** microstructure and deposition properties of 7 YSZ coating along the radius of plasma jet were investigated in *** show that the coating presents regional characteristic in the radial direction,which could be divided into three typical zones:In Zone Ⅰ,the coating is all composed of columnar structures with cauliflower structure,and the coating properties including the surface roughness and deposition efficiency(DE) are almost stable;in Zone Ⅲ,the coating is made up of solid particles,droplet and gas phase mixed without columnar structures;Zone Ⅱ is between Zone Ⅰ and ZoneⅢ, in which there are columns with domed top and small *** on experiment results,a model on the state and distribution of particles in plasma jet was proposed to clarify the regional *** study is helpful to comprehend and control coatings deposition by PS-PVD technique.
