Gas-path seal material
Abstract
Composite sealant reduces frictional heating, wear, and leakage. Sealant is needed to reduce wear of rotating compressor-blade tips if they rub against stationary engine casing. Nickel substrate with plasmasprayed aluminum top layer was evaluated. Results showed little wear on top layer took place; layer itself remained intact and provided heat conduction pathway from rub surface.
