PROBLEM TO BE SOLVED: To disclose a compliant seal (20, 30) used between a rotational blade (16, 26) and a static shroud (18, 28) surrounding the rotating blade (16, 26) in a steam or gas turbine (10). SOLUTION: The present seal (29, 30) includes a tip surface (36), substantially resistant to wear due to rubbing by the tip of the rotating blade (16, 26), and an elastic biasing member (38), comprising a biasing element. A wear-resistant surface (36) is thus biased against the tip of the rotating blade (16, 26) to seal a gas path between the rotating blade (16, 26) and the static shroud (18, 28).
