发明名称 PT-IR-BASED WIRE HARDENED BY OXIDE DISPERSION AND OTHER ALLOYS PROVIDED WITH AN IMPROVED SURFACE FOR SPARK PLUG ELECTRODES
摘要 A wire, strip or reshaped part is produced from an alloy based on platinum, palladium or a mixture of platinum and palladium and hardened by oxide dispersion. The wire, strip or reshaped part cross-section exhibits a peripheral zone in which at least one relatively easily volatilized oxide generator is depleted by at least 25%. In addition, a process is provided for production of such a wire, strip or reshaped part, in which a porous skin is produced thermally on the wire, strip or reshaped part, and the porous skin is compacted by conversion into a soft or impermeable skin.
