Definitions

  • the invention relates to a workpiece coated with a layer system according to the preamble of patent claims 1 and 4, and to a method for producing such a workpiece according to the preamble of patent claims 18 and 20.
  • Preferred embodiments of the invention are in the corresponding dependent claims 2 to 3, 5 to 17, and 19 and 21 to 27 claimed.
  • US Pat. No. 4,573,690 discloses a body moved against a sealing ring with defined depressions on the surface and a mechanical method for producing the depressions.
  • the latter in use, cause pressure fluctuations of a lubricant introduced between the sealing ring and the body, which is to avoid tearing off the lubricating film and thus direct contact with solid surfaces.
  • No. 5,473,138 describes a method for enlarging metallic and ceramic surfaces by means of laser radiation.
  • WO 98/14710 describes a method for producing a plain bearing, with an optimized pore distribution, for example is generated by means of a pulse laser on a sliding surface of a bearing.
  • a disadvantage of the above-mentioned components is that, in the event of insufficient lubrication conditions, contact between two materials that are similar or even identical in terms of their surface properties is still possible. Cold welding or seizure of, for example, a metallic material combination (eg sealing ring / counter body) cannot always be reliably avoided under such conditions. This also applies in particular to complex machines with tribologically stressed parts, on which, due to high relative speeds and / or surface pressures, conditions of insufficient lubrication and correspondingly increased wear can occur. Examples from engine construction are valve drives in modern, high-performance internal combustion engines, in which bucket tappets and piston rings in particular are exposed to extremely high loads. Tools with a textured surface structure are also known from U. Popp et al.
  • microstructures into a layer system applied at least partially on the functional surface (s) of a workpiece such that the vertical expansion of the (three-dimensional) microstructure extends from the surface of the layer system through the layer into the workpiece extends so that it is uncoated in a lower region of the structure.
  • a ratio d / s of the layer thickness d to the structure depth s between 0.05 and 0.9, preferably between 0.1 and 0.6.
  • the for setting the retention of lubricants as well as the structural depth • and geometry substantial area coverage, ⁇ ie the ratio of the surface of the microstructure to the total with a textured pattern provided surface was set between 10 and 50%, the best results but with a degree of area coverage achieved by 15-35%.
  • the cross section of the recesses was used for small structures or structural cross sections, i.e. Structures with the largest lateral dimension between 5 and 350 ⁇ m, circular, but preferably chosen conical.
  • the tangential angle i.e. the angle between the surface horizontal and a straight line that is intended to be adjacent to the sloping structure flank, as flat as possible, i.e. below 20 °, but preferably below 10 ° or 5 °.
  • the structures were produced using a laser beam, with circular structures being produced for the sake of simplicity.
  • circular structures being produced for the sake of simplicity.
  • differently shaped structures for example circular, elliptical, linear, triangular, quadrangular or polygonal, or else more complex structures, can also be used advantageously in individual applications.
  • test results also surprisingly showed that workpieces coated with DLC and with Me / C, MeC / C or WC / C sliding layer systems, even with conventionally produced structures, significantly improve the tribological properties compared to structured hard layers such as e.g. Enable TiAlN or previously known structured TiN layers.
  • aC: H: Si, ie silicon / carbon layers, aC: H: Si: Me, ie silicon / carbon / metal layers, aC: H / a- Si: 0, ie carbon / silicon oxide layers are suitable, which can be produced with properties similar to the above-mentioned carbon-containing layers.
  • tungsten In addition to the tungsten mentioned here, other metals, such as Ti, Zr, Hf, V, Nb, Ta, Mo, or Fe, but preferably Cr for the Me / C, MeC / C and aC: H: Si: Me layers are used. A combination of several metals is also possible.
  • the first layer of the layer system is advantageously an adhesive layer consisting of one or more metals of the abovementioned selection. If the layer system consists of at least one hard layer and at least one carbon-containing sliding layer, an additional metallic intermediate layer which separates the hard layer and sliding layer can be advantageous. A combination of several metals, in particular those mentioned above, is also possible.
  • graded layer transitions can also be used to optimize the layer properties. For example, it is advantageous to provide carbon-containing layers with a proportion of carbon rising from a metallic adhesive layer towards the surface.
  • the total layer thickness of the layer system can be set between 0.5-20 ⁇ m depending on the planned application. Due to the abrasive wear due to the introduction of particles, which often also occurs in lubricated tribological systems, a minimum layer thickness of one micrometer is preferable in many cases. Due to the economics of the process when depositing PVD layers, a maximum layer thickness of approx.
  • Layers structured according to the invention can be used particularly advantageously on components which have at least one functional surface designed as a sliding surface. Examples of this are plain bearings, sliding seals, sealing rings, piston rings, bucket tappets, rocker arms or crankshafts.
  • Layers structured according to the invention can also be applied to tools which have at least one functional surface designed as a sliding surface.
  • tools which have at least one functional surface designed as a sliding surface. Examples of this are, in particular, cutting tools with at least one rake face for turning, broaching or milling applications or forming tools with at least one extrusion surface such as, for example, massive solid forming tools.
  • these are first coated using a combined PVD / CVD process, a layer system having been deposited on the functional surface.
  • an adhesive layer is applied using a PVD sputtering process and then an increasing proportion carbon-containing gas mixed with the working gas.
  • this proportion is increased to a desired maximum value and the coating process is then stopped (reactive PVD process step).
  • the layer system is to be completed with a DLC layer, the sputtering process is stopped at a certain point in time, a pulsed bias voltage is applied to the substrate, and the DLC layer is then deposited.
  • This last process step corresponds to a CVD process, since no physical evaporation takes place here. Further information on the methods used can be found in the examples below.
  • the structuring after the layer system had been applied to at least part of the functional area (s) was carried out using laser processing systems from different companies (for example Lambda Physik, SurTech, CMT Rickenbach).
