Abstract The thermal barrier coatings (TBC),which Ni30C r12Al0.3Y bond coating was deposited by magnetron sputtering and ZrO2 ceramic top coating was deposited by electron beam-physical vapor deposition (EB-PVD),wa s produced on Ni-base superalloy.The bond coatings,which the mean grain size was less than 100 nm,were nanostructured coatings,and had good oxidation-resist ance.The ceramic topcoats,which were columnar structure,permitted larger strain in the coatings.The as-deposited ceramic coatings consisted of large quantity no nequilibrium tetragonal (t′),a small amount cubic (c) and monoclinic ( m) phases.The t′ phases,which had important role to the stabilization o f zirconia at high temperature,can not directly transform into m phase during co oli ng.During cyclic oxidation at 1050℃,the scale of the cast alloy had spalled aft er two cycles.After 100 cycles,the surface scale of single-crystal superalloy wa s mainly composed of NiO、Cr2O3,a little Al2O3 and pores by the Kirkenda ll effect.However,the ceramic coatings,which had microcrack,have not spalled and the thermally grown oxide (TGO) was Al2O3.There were some microcrack betwee n TGO and bond coating after 300 cycles.
