摘 要:To solve the long-standing contradiction between the bonding strength and abradability of an abradable seal coating(ASC),a novel spherical closed-pore structure was proposed.The new structure consisted of three discontinuous phases,including locally enriched metals,hollow thin-shell spheres,and pores.The results show that the bonding strength of the abradable seal coating reaches 25.4 MPa,and the abrasion ratio between the coating and blade tip,as a characteristic of the abradability of ASCs,is>5900.The dewetting kinetics of the metal film on the ceramic sphere were calculated.The size of the shrink metal hemisphere is 3.6 times the metal film thickness.The locally enriched metal enables a high bonding strength,while the fragmentation of the hollow thin-shell spheres enhances the abradability,thus simultaneously improving the strength and abradability.The coating is expected to be used in next-generation turbines to improve efficiency and stability.
