Abstract

The discharge portions of sparking plug electrodes are made from an alloy having one or more members of the platinum group of metals as the major constituent whilst the surfaces of the discharge portions are impregnated with chromium as described in Specification 646,641. Specification 448,913 [Group XXVII] also is referred to.
