Definitions

  • the present invention relates to an electrode for a spark plug and a method of manufacturing the same, wherein excellent durability of a noble metal element is provided on an electrode base material.
  • an electrode for a spark plug in which a noble metal chip is welded onto a base material of the electrode by means of laser welding. This results in a large melting section of fused together materials of the base electrode and the noble metal platelet of more than 50 vol .-% of the noble metal platelet. This makes it necessary to use a large amount of expensive precious metal for the production of the electrode. However, this leads to high production costs of the electrode.
  • the method according to the invention with the features of claim 1 has the advantage that an amount of noble metal for the electrode can be significantly reduced.
  • a weld joint is now produced between the noble metal element and an electrode base material having a ratio of a maximum depth T of the weld perpendicular to a surface of the electrode to a maximum width B of the weld at the electrode surface greater than or equal to 3 (T / B ⁇ 3).
  • the noble metal material is fused to the electrode base material in the weld. This will ensure that the weld does not become excessively thick and sufficient noble metal material is present for a long durability of the spark plug.
  • a volume of the noble metal element before welding is in a range of 0.015 to 0.2 mm 3 , preferably 0.075 to 0.15 mm 3, and more preferably about 0.1 mm 3 .
  • the ball preferably has a diameter of 0.3 to 0.75 mm, preferably 0.4 to 0.6 mm, and more preferably about 0.5 mm.
  • the noble metal element is a noble metal chip, preferably with a cylindrical shape having a diameter between 0.4 to 2.6 mm.
  • the diameter is preferably between 0.4 to 0.8 mm, preferably 0.5 to 0.7 mm, and particularly preferably about 0.6 mm.
  • the diameter is preferably between 2.2 to 2.6 mm, and is preferably about 2.4 mm.
  • a thickness of the noble metal chip is preferably in a range between 0.2 to 0.7 mm, preferably 0.25 to 0.6 mm, and more preferably about 0.3 mm.
  • the thickness is preferably about 0.3 mm, for stationary gas engines preferably about 0.6 mm.
  • the weld is provided substantially perpendicular to an electrode surface.
  • the weld is at an angle to the electrode surface, preferably at an angle of 0 ° to 60 ° provided.
  • the weld is formed without interruption on the outer circumference of the noble metal element. More preferably, a maximum width of the weld in a range of 0.1 to 0.3 mm, and more preferably about 0.2 mm. A maximum depth is preferably in a range of 0.3 to 0.9 mm, and more preferably 0.6 mm.
  • FIGS. 1 to 3 an electrode for a spark plug 1 according to a first embodiment of the invention described.
  • the spark plug 1 comprises a ground electrode 2 and a center electrode 3, which is arranged in a center axis XX of the spark plug.
  • the electrode according to the invention is the ground electrode 2. It should be noted, however, that the electrode according to the invention can also be the center electrode 3 or both electrodes can be designed in accordance with the invention.
  • the ground electrode 2 has a surface 20 which is directed to the other electrode and is arranged perpendicular to the central axis XX.
  • the center electrode 3 has a surface 30, which is directed towards the ground electrode and is also aligned perpendicular to the central axis XX.
  • the ground electrode 2 comprises an electrode base material 4 made of a material which does not contain a noble metal, for example a nickel alloy. Furthermore, the ground electrode 2 comprises a noble metal element 5, which by means of a welded joint 6 is fixed to the electrode base material 4.
  • the noble metal element 5 is a ball in this embodiment, and the welded joint 6 is annularly formed around the ball, as in FIG FIG. 2 shown.
  • the welded joint 6 is formed such that the welded joint 6 in the axial direction XX has a maximum depth T, ie maximum extent of the weld parallel to the central axis XX. Parallel to the surface 20, the welded joint 6 further has a maximum width B at the surface (see also FIG. 2 ).
  • the width B of the welded joint 6 is defined as the maximum length of the weld in a radial direction from the center axis XX of the spark plug to the surface of the welded joint 6.
  • the welded joint 6 of this embodiment is made by means of a fiber laser so that high beam quality is ensured to make the weld 6 as homogeneous as possible.
  • the welding operation for fixing the noble metal element 5 to the electron base material 4 is carried out in one step before the ground electrode 2 is bent by 90 °.
  • An original diameter of the spherical precious metal element was 0.5 mm.
  • a fiber laser which produces a very exact weld seam with a very constant width and a very constant extension in the axial direction XX of the spark plug can be.
  • another laser can be used for welding.
  • the present invention surprisingly demonstrates a way in which precious metal can be saved in spark plugs without thereby reducing the durability of the spark plug.
  • a production of the spark plug can be cheapened by the saving of precious metal. Since spark plugs are mass components, this results in great savings potentials.
  • the durability of the spark plug can be further improved if both the ground electrode 2 and the center electrode 3 have a noble metal element welded in accordance with the definition of the aspect ratio of ⁇ 3 according to the invention.
  • FIGS. 4 to 6 show alternative embodiments of the invention, wherein identical or functionally identical parts are denoted by the same reference numerals as in the first embodiment.
  • FIG. 4 shows the use of a platelet of noble metal as the noble metal element 50.
  • the noble metal chip is formed as a smaller cylinder and welded to the electrode base material 4 by means of a welded joint 6. While in the first embodiment in the FIGS. 1 to 3 approximately a depth of the weld in the axial direction XX defined the axial extent of the weld, in the second embodiment, the axial expansion of the weld 6 is formed largely at the lateral peripheral edge of the noble metal element 50. Also, this aspect ratio of the maximum depth T to the maximum width B at the surface of the electrode is greater than or equal to 3.
  • a noble metal chip 50 is used as a noble metal chip.
  • the main welding direction is no longer selected substantially parallel to the central axis XX, as in the second exemplary embodiment, but at an angle ⁇ of approximately 40 °.
  • a funnel-shaped welded joint 6 is obtained, which lies partially below the noble metal element 50.
  • an aspect ratio T / B ⁇ 3 is also with this Welded joint 6 and is an aspect ratio T / B ⁇ 3, wherein the width B of the welded joint 6 is given by a projection of the maximum radial to the central axis XX directed propagation of the weld 6 at the surface.
  • FIG. 6 shows a fourth embodiment of the invention, wherein the noble metal element 5, which was originally also a ball, is welded from an opposite opposite side 21 at the ground electrode 2 ago.
  • the noble metal element 5 which was originally also a ball, is welded from an opposite opposite side 21 at the ground electrode 2 ago.
  • this results in no annular weld, as in the preceding embodiments, but a substantially cylindrical weld, which extends from the opposite side 21 to a foot region of the precious metal element 5.
  • the weld joint 60 is made such that it does not leak out of the noble metal element 5 on the surface 20 facing the center electrode. This results in a particularly large area of the noble metal element 5, which is directed to the center electrode.
  • the welded joint 60 of this embodiment is formed in the center axis X-X of the spark plug and slightly tapered toward the noble metal element 5.
  • a width B of the fourth embodiment corresponds to a diameter of the welded joint 60 on the opposite side 21.
  • An extending in the direction of the center axis XX extension of the welded joint 60 corresponds to the depth T of the welded joint in the ground electrode 2.
  • an improved electrode for spark plugs can be provided, which has a very high durability despite lower precious metal use. It can also be ensured according to the invention that a weld seam is kept relatively small.
  • noble metal elements with a volume in the range of 0.015 to 0.2 mm 3 are weldable, with 50% or less of the noble metal volume being fused to the electrode base material.
