  • METHOD OF MAKING ABRADABLE SEAL HAVING IMPROVED PROPERTIES
    Publication number: 20010055652
    Abstract: An air seal for use in a gas turbine engine provides improved durability, particularly at higher temperatures. The seal includes a seal substrate, and an abradable layer is provided on the substrate by a thermal spray process, with the abradable including a thermoset polymer and a thermoplastic polymer. The abradable may also include a filler to add porosity, or provide lubrication, to enhance abradability.
