    摘要： A spark plug for an internal combustion engine includes a middle electrode which has an electrode base body (5) with an end face (51) oriented toward the combustion chamber, to which end face a precious metal platelet (8) is attached. An end section (15) of the electrode base body oriented toward the combustion chamber is formed in the shape of a truncated cone. The precious metal platelet (8) is likewise formed in the shape of a truncated cone and the diameter of the end face (52) of the electrode base body oriented toward the combustion chamber corresponds to the diameter of the end face (84) of the precious metal platelet oriented away from the combustion chamber. A method for producing middle electrodes for a spark plug of an internal combustion engine is also proposed.

    摘要： An electrode and spark plug for an internal combustion engine including an electrode of this type as a center electrode. The electrode includes an electrode base element made of a first material and an end section that is integrally joined to the electrode base element, with this end section including a first area that is integrally joined to the first material and is made of a platinum-containing material and including a second area that is integrally joined to the first area and is made of an iridium-containing and/or ruthenium-containing material. In a method for manufacturing an electrode of this type, a first recess is stamped in the electrode base element, a first preform is inserted into the first recess, the first preform is melted, thereby forming a first alloy, a second recess is stamped in an area of the first alloy, a second preform is inserted into the second recess, and the second preform is melted, thereby forming a second alloy.

    摘要： An electrode for a spark plug includes an electrode base material and a noble metal element, the noble metal element being fastened to the electrode base material using a welding connection. The welding connection has a maximum extension perpendicular to an area of the electrode at which the noble metal element is fastened, and the welding connection has a maximum width at the area. A ratio of the maximum extension to the maximum width is greater than, or equal to 3.
