A biased, wear resistant seal assembly for sealing gas flow paths in a turbine system includes a planar shim (26) having transverse legs (32,34) at each end, a flattened leaf spring (38) to urge the shim (26) into sealing contact with the sealing surfaces (18, 24) of the turbine parts (10,12), and a shim protection material (46) to avoid wear to the shim (26) on the contact side (18). The shim protection material (46) can include one or more metal fiber cloth layers secured to the shim (26), for example, by seam welding to a pair of rails (52) or to the legs (32,34) of the shim (26).
