    摘要: An electrode is provided for a spark plug made of a base material and at least one additive material situated in the base material in a dispersedly distributed manner, which is intercalated in the base material, and is a metal oxide, and is characterized by a negative enthalpy of formation greater than 800 kJ/mol O2. The base material is an Au based or an Rh based material or is pure Au or Rh, the proportion of the additive material amounting to between 5 vol. % and 50 vol. %. Alternatively, Pt-based materials or pure Pt are provided as the base material, the proportion of the additive material at average particle diameters of the additive material between 5 μm and 20 μm amounting to between 21 vol. % and 50 vol. % or the additive material being at least one metal oxide from the group of the rare earth metal oxides and/or at least one metal oxide from the group Al2O3, Y2O3, Sc2O3, CaO, SrO, BaO and/or at least one mixed oxide, such as spinel, made up of at least one alkaline earth metal oxide, one rare earth metal oxide, Al2O3, Y2O3 and/or Sc2O3, the proportion of the additive material amounting to between 5 vol. % and 50 vol. %.

    摘要: A spark plug for an internal combustion engine is proposed, having at least two electrodes (9, 11), one of which at least two electrodes is at least one middle electrode (11) and another electrode of the at least two electrodes is at least one ground electrode (9), and between the at least one ground electrode (9) and the at least one middle electrode (11), a spark gap (13) is formed. Each of the at least two electrodes (9, 11) has an electrode base body (93, 113). At least one electrode has a region (95, 115) that is highly resistant to electrode erosion and that forms at least a part of the end face, oriented toward the spark gap, of the electrode (97, 117). The highly electrode-erosion-resistant region (95, 115) comprises an alloy which has at least the elements iridium and nickel.

    摘要: A spark plug having a ceramic insulator, which contains a precious-metal center electrode in a cylindrical, axial opening, at the end on the side of the combustion chamber. A contact pin is arranged in the cylindrical opening, downstream from the precious-metal center electrode, in the direction of the insulator end away from the combustion chamber. To reduce corrosion, the surface of the contact pin is provided with a layer of one or more metal aluminides.
