Turbine blade, especially for a gas turbine, comprises at least one chamber impinged upon by a coolant and at a rear edge (26) a gap (25) defined by two walls (28, 29) for exiting coolant. At least one of the walls is post-treated to reduce the cross-section of the gap. The cross-section of the gap is altered by changing the length (L) of at least one of the walls, preferably the wall on the pressure side. An Independent claim is also included for a process for producing the above turbine blade. |
