  • Composite metal seals for use in rotary internal engines
    Patent number: 3947161
    Abstract: A composite metal rotor tip seal for use in rotary internal combustion engines and a process for making a composite rotor tip seal. The composite seals are formed from at least two different metals or alloys having different frictional and wear characteristics whereby uniform wear and improved sealing are obtained. The seal is mounted so that different components of the composite contact the chamber wall during operation. A process for producing composite material, for the fabrication of composite seals, utilizing a pressure welding process is also described.
    Type: Grant
    Filed: July 22, 1974
    Date of Patent: March 30, 1976
