Definitions

  • the invention relates to a sliding element, in particular a piston ring, with a coating and a combination of a sliding element with a running partner.
  • Piston ring can be seen with a cylinder liner.
  • the cylinders or cylinder liners are made of, for example, aluminum-silicon alloys, which is the case in particular for gasoline engines, DLC (diamond iike carbon) coating systems have proven to be effective in terms of wear and friction.
  • DLC diamond iike carbon
  • the known DLC layer systems are diesel or high in terms of service life as well as their applicability
  • Layer thicknesses are also known PVD coatings, in particular based on CrN, the layer thicknesses in the range of 10-30 ⁇ have. Although this results in an improved life, but deteriorates the
  • Friction loss and wear resistance especially in case of insufficient lubrication, as well as fire safety.
  • DLC layer systems offer the advantage of exhibiting a largely chemical inactivity with metallic surfaces and thus an extremely low adhesive tendency towards the iron on the track.
  • DE 296 05 666 Ul relates to a component in the region of an internal combustion engine, which is coated with a metal-free, amorphous carbon layer whose hardness profile over the layer thickness is graduated.
  • DE 10 2008 016 864 B3 discloses a piston ring which has, from the inside to the outside, an adhesive layer, a metal-containing, amorphous carbon splint and a metal-free, amorphous carbon layer.
  • WO 2009/106201 AI relates to a component of a
  • WO 2006/125683 A1 shows a piston ring which has, from the inside to the outside, a layer with an element of groups IVB, VB or VIB, an intermediate layer with a diamond-like nanocomposite composition and a DLC layer. Presentation of the invention
  • the invention has for its object to provide a sliding element, in particular a piston ring, which in particular when used in diesel or highly charged petrol engines with, for example, iron-based running partners the
  • Frictional performance met. Furthermore, a suitable combination of a sliding element with a running partner should be specified.
  • the DLC layer is either metal-free or has one
  • the DLC layer is at least partially metal-free and in particular has a metal-free DLC layer on the outer surface. Furthermore, extensive tests have shown that a particularly good behavior of the coating described occurs when an intermediate layer is provided between the CrN and the DLC layer as Me (C x Ny) layer. For this layer structure was found in experiments that the
  • the CrN layer is preferably applied to the piston base material without an adhesive layer, for example by metallic vapor deposition or sputtering.
  • the CrN layer may be special Applications be attached by means of an adhesive layer to the base material of the sliding element.
  • Me stands for metal and, for example, tungsten, chromium, titanium or silicon can be used for this purpose.
  • carbon and nitrogen may be present in almost any proportion in the described layer, i. H. both x and y can range from 0-99 atomic percent.
  • the coating can be provided, in particular at least partially, on at least one running surface. Further, the coating may extend into the transition to surfaces and to surfaces adjacent the treads. This concerns, for example, the running flanks of a piston ring.
  • the metal-containing DLC layer may also advantageously nanocrystalline Metallcarbarbscheidiens, such as. WC, CrC, SIC, GeC or Tic.
  • the top layer forming the surface has a roughness Rz of ⁇ 5 ⁇ m and / or Rpk of ⁇ 0.8 ⁇ m.
  • the invention further relates to a combination of at least one sliding element described above with a

  • Figure 2 shows the relative wear of a piston ring
  • a CrN layer 12 is applied to the base material 10 of the sliding element.
  • the adhesive layer 14 shown in FIG. 1 does not necessarily have to be provided. In particular, it is preferred to omit them.
  • a Me (C x Ny) intermediate layer 16 of the outside of a DLC layer 18 is provided, the
  • the "Series DLC” system is a standard DLC coating system without CrN
