Abstract

There is provided a fluid flow machine (10) comprising: a casing structure (24), a turbomachine blade (311) disposed within the casing structure (24), and a sealing arrangement (330) coupled to the casing structure (24). The sealing arrangement (330) comprises (330) an abrasion portion (334) including a lattice structure (400). The abrasion portion (334) is configured to provide a seal with a tip (321) of the turbomachine blade (311). The abrasion portion (334) includes the lattice structure (400) having a lattice density that increases along a radial direction (42) of the machine (10).There is also provided a method (600) of manufacturing such a fluid flow machine (10).
