Abstract:
An abradable turbine component, a method of creating a turbine component with an abradable mesh structure, and a gas turbine engine are provided. The abradable turbine component includes a turbine component surface for coupling to a turbine casing, and a deposited abradable mesh structure coupled to the turbine component surface. The abradable mesh structure includes interlacing strands of material, each strand including a height relative to the turbine component surface. At least two of the plurality of interlacing strands include a height different from each other. The method includes applying a bond coat layer followed by a thermal barrier coating layer. An abradable mesh structure is deposited on top of thermal barrier coating wherein the abradable mesh structure includes interlacing strands of material wherein at least two of the interlacing strands include a height different from each other. A gas turbine engine including the abradable turbine component is also provided.
