Wire of oxide dispersion hardened platinum and/or palladium alloy, for use as spark plug electrode, has impermeably edge zone with reduced oxide former content to provide improved deformability |
摘要 |
<p>A wire of oxide dispersion hardened alloy (I) based on platinum and/or palladium has an edge zone of the wire cross-section in which the relatively volatile oxide former(s) is diluted by at least 25%. An independent claim is included for the production of a wire of (I), in which (a) a porous skin is thermally created on the wire of (I) and (b) the porous skin is compressed by deformation to give a soft or impermeable skin.</p> |
