Abstract

Gas turbine rotor blade assembly (12) and corresponding gas turbine (50) having a plurality of stages and a plurality of blades (58) coupled to each respective stage includes depositing a silicone oxime sealant (150) onto at least a portion of a compressor blade, and coupling the compressor blade to a compressor disk (56) such that the silicone oxime sealant is between the compressor blade and the compressor disk.
