中文摘要The stratified gradient thermal barrier coatings (TBCs) were obtained by laser cladding of ZrO2 and NiCoCrAlY mixture powder. The coatings were four-layer structure: cellular dendritic ZrO2, dense ZrO2, Ni-based alloy bonding coating and substrate. The formation of the stratified TBCs was attributed to the insolubility of ZrO2 in the Ni-based alloy and the lower density of ZrO2 than that of Ni-based alloy when both of them were in melted condition. The formation of two-layered ZrO2 was related to the presence of Al in the Ni-based alloy, i) Al could be preoxidized into Al2O3 that could be segregated in the grain boundaries of ZrO2 during solidification process; ii) Al could be partially preoxidized into Al2O3, then Al and Al2O3 could be segregated simultaneously at the grain boundaries of ZrO2 during solidification process. Two formation processes were presented.
