摘要： A spark plug for an internal combustion engine is disclosed, with a middle electrode, comprising an electrode base body (5), with a front face (51), facing towards the combustion chamber, to which a noble metal tip (8) is attached. A combustion chamber facing end section of the electrode base body (15) is in the form of a frustum. The noble metal tip (8) is also in the form of a frustum, whereby the diameter of the front face of the electrode base body (51), facing towards the combustion chamber, corresponds to the diameter of the front face of the noble metal tip (84), facing away from the combustion chamber. Furthermore, a method for the production of a middle electrode for a spark plug in an internal combustion engine is disclosed, whereby a noble metal tip (8) is fixed to an electrode base body (51), with the front face of the electrode base body (51), facing the combustion chamber, connected to the front face of the noble metal tip (84), facing away from the combustion chamber. Finally, the noble metal tip (8) and the combustion chamber end of the electrode base body (5) are machined into a cone in such a way that an external section (11), in the boundary region between the noble metal tip (8) and electrode base body (5) is removed, which, in terms of the microstructure and/or composition thereof, differs from that of an internal section (12) of the boundary region.

摘要： Applying a precious metal tip (1) to an electrode (5) comprises welding the tip to the electrode; and fusing the tip in a first region and the electrode in a second region to form a mixed alloy. The first region is selected so that it completely surrounds the material of the tip. Independent claims are also included for the following: (i) the electrode used in the process; and (ii) a spark plug comprising an electrode and a precious metal tip. Preferred Features: The welding step is a resistance welding step. Both regions are fused using a laser having a pulse of approximately 1 kW for approximately 10 ms. The electrode is made from nickel or a nickel alloy. The tip is made from gold, iridium or platinum.

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.
