Abstract (en)
[origin: WO2007019990A1] The invention relates to a wire or strip made of an alloy hardened by an oxide dispersion which is based on platinum or palladium or the mixture thereof and is characterised in that the wire or strip cross-section comprises an edge area in which a relatively easily volatile oxide generator is reduced at least by 25 %. A method for producing the wire or strip made of the alloy hardened by the oxide dispersion which is based on platinum or palladium or the mixture thereof is also disclosed. The inventive method consists in thermally producing a porous skin on the wire or strip made of the alloy hardened by the oxide dispersion and in compressing said porous skin in the form of a elastic or impermeable skin.
