  • Patent  /  Elektronische Ressource

Wie erhalte ich diesen Titel?

Aspects are directed to a tribological and creep resistant system (400) configured to operate at temperature in excess of 750°C, comprising: a piston seal (404) that includes a nickel base alloy, where the nickel base alloy includes a Ni 3 (Al,X) type precipitated phase in an amount greater than 40% by volume. Aspects are directed to a system (400) comprising: a piston seal (404) that includes a cobalt-based alloy. Aspects are directed to a method comprising: heat treating an ingot of a nickel base alloy that includes coarsening a precipitated phase to facilitate forging or wrought forming the ingot, machining the ingot to include a substantially flat surface, and processing the ingot to generate a piston seal (404).
