摘要
Abstract
Electric spark deposition (ESD) combining with micro-arc oxidation (MAO) were employed to fabricate ZrO2/NiCrAlY thermal barrier coating (TBC) on GH4169 substrate.Firstly,a NiCrAlY coating with thickness of 250 μm was deposited on GH4169 substrate by ESD.Secondly,a Zr coating with thickness of 150 μm was deposited on NiCrAlY coating followed by MAO of the Zr coating.The thermal shock performances of the coatings under different temperatures were investigated.The results indicate that the thermal cycle numbers of the coatings at 750℃,850 ℃ and 950℃ are 51,32,and 19 respectively.关键词
