| Abstract: | A nanostructured zirconia coating was deposited by air plasma spraying on nickel-based superalloy substrate. The microstructure of the coating was characterized by scanning electron microscopy. The microhardness, bonding strength and thermal shock resistance were tested. The results showed that the coating consists of a fully molten zone and a partly molten zone, and has porosity about 7%, micro-hardness 655.81 HV and bonding strength 54.37 MPa. No signs of peeling-off were observed for the coating tested a... |
