Definitions
- the invention relates to a machine part, which belongs to a sliding pair with two mutually movable machine parts of a large engine, in particular a two-stroke large diesel engine, and at least in the region of the other machine part side facing a wear-resistant structure with recorded in a metallic matrix particles of relatively hard material and having a rough and uneven surface and which is designed as a piston ring or cylinder liner or piston with at least one piston ring groove or other sliding element of a large engine.
- the wear protection coating consists of ceramic particles embedded in a matrix formed by a Ni alloy.
- a thin, consisting only of the matrix material cover layer is provided at the top of the coating.
- the surface of this cover layer proves, however, as practice has shown, as very rough and uneven, which is unfavorable for a run-in process. It is therefore a machining in the form of a grinding process required. Experience has shown that this is very time consuming and costly.
- the Ni alloy is in any case unfavorable due to its hardness for intake purposes.
- Another object is to provide a simple and inexpensive method for producing the inventive machine part.
- the first part of the object is achieved by applying to the wear-resistant structure a top unevenness and roughness compensating inlet application consisting of a running-in material suitable for wear during an inlet operation, different from the materials of the wear-resistant structure underneath and metallurgically connected to the wear-resistant structure and which is softer than the wear-resistant structure and at most equal wear-resistant as the sliding surface of the respective opposite machine part.
- a top unevenness and roughness compensating inlet application consisting of a running-in material suitable for wear during an inlet operation, different from the materials of the wear-resistant structure underneath and metallurgically connected to the wear-resistant structure and which is softer than the wear-resistant structure and at most equal wear-resistant as the sliding surface of the respective opposite machine part.
- the inlet support consists of inlet material, good shrinkage properties are to be expected. Since the inlet support compensates for the roughness and unevenness of the underlying, wear-resistant structure, an abrasive machining is unnecessary dispensable. In addition, this ensures that even in the upper zones are located, hard particles of the wear-resistant structure even then find a reliable stop when their surface is exposed towards the end of the inlet process, so that breaking of these particles is not to be feared. The unpolished surface results in an advantageous manner from the beginning to a gas-tight system, which is very desirable especially for sliding mating between the piston ring and cylinder liner.
- Another advantage of the measures according to the invention is the fact that, as a result of the metallurgical connection of the inlet support, a reliable hold of the inlet support on the underlying, wear-resistant structure is ensured, so that peeling is safely avoided.
- the inlet support may suitably have a hardness of 100 to 200 HV.
- a particularly good run-in behavior is to be expected. Nevertheless, sufficient durability is guaranteed to ensure a sufficiently long break-in period to make sure.
- a further development of the parent action may consist in that the material forming the running-in rest has a melting temperature of below 1050 0 C 1, preferably from 600 ° C to 800 ° C.
- This measure advantageously allows a simple production of the inlet support, in which only the material of the inlet support is melted and the material of the underlying, wear-resistant structure remains in the solidified state. This ensures that very thin, the metallurgical connection of the inlet support to the underlying, wear-resistant structure causing boundary layers can be achieved. The brittleness which is frequently to be expected in these boundary layers therefore advantageously has only a slight effect on the overall result.
- the inlet support in the new state an average thickness of 50 to 300 microns (microns) have.
- a thickness is sufficient for an inflow time of 1000 to 2000 hours, whereby the abrasiveness of the opposite sliding surface can be accommodated by adjusting the thickness.
- a further development of the superordinate measures may consist in that the inlet support in the new state has a surface roughness of 1 to 20 Ra. This makes post-processing completely unnecessary and still ensures a particularly good seal from the beginning.
- a particularly expedient development of the higher-level measures may be that, in contrast, harder particles, preferably of ceramic material, such as Al 2 O 3 and / or CrO and / or Cr 3 C 2 , are incorporated into the inlet material on which the inlet support is based.
- harder particles preferably of ceramic material, such as Al 2 O 3 and / or CrO and / or Cr 3 C 2
- the proportion of the deposited particles in the total volume of the inlet support in the range between 5 to 30% by volume. This ensures that the embedded particles do not unduly impair the run-in behavior can.
- the inlet material underlying the inlet support at least copper (Cu) and / or tin (Sn) included. This allows an optimization of the desired inlet properties depending on the individual case.
- a particularly advantageous embodiment may consist in that the inlet support contains about 70% copper (Cu) and about 30% tin (Sn). Such a material is advantageously usable in many cases. It is also conceivable to add an additional component of antimony (Sb). This creates a so-called. White metal, which finds use in practice as a bearing metal and therefore is available at low cost.
- the wear-resistant structure accommodating the run-in support may expediently comprise a matrix formed by a Ni alloy, in which particles consisting of ceramic material are embedded, wherein the volume fraction of the ceramic material in the total volume of the wear-resistant structure may be more than 60%, preferably 85% , These measures result in a particularly high load-bearing capacity and wear resistance.
- the melting temperature of the matrix can be lowered below the melting temperature of cast iron, etc., which can facilitate the application of the inlet support to the wear-resistant structure and / or this on a base body.
- the object relating to the method is achieved according to the invention in that the machine part having a wear-resistant structure is coated with an inlet support covering the wear-resistant structure, so much energy being supplied during the coating process of the wear-resistant structure and / or the material forming the inlet support there is a desired metallurgical connection of the inlet support to the wear-resistant structure. If a thick boundary layer between wear-resistant structure and inlet support is desired, so much energy is supplied that the inlet support is alloyed. On the other hand, where this is not desired, the energy supply is reduced so much that the inlet support is diffused. there Only so much energy is needed that only the material forming the inlet support melts and the wear-resistant structure underneath remains in the solidified state. As a result, comparatively thin boundary layers are achieved in this case. In addition, damage to the supporting structure is excluded.
- a relative to this relatively movable, on this one Walkerfleck generating heater can be used for coating the wear-resistant structure, wherein the inlet material forming the inlet material is fed into the Schufleck or a directly adjacent this area.
- This allows a simple construction of the coating apparatus, as well as a controlled supply of energy within narrow limits.
- the material supplied to the heating spot or to a region directly adjacent to it can be supplied in powder form and / or in the form of a wire or ribbon.
- Figure 1 shows an application example in the form of a cooperating with a cylinder liner, provided with a supporting structure and arranged thereupon inlet piston ring in section;
- Figure 2 shows a detail of the inlet support with adjacent region of the wear-resistant structure
- Figure 3 shows a detail of a with embedded ceramic particles provided inlet pad
- Figure 4 shows a coating device with two laser guns, each with associated feed device for the wear-resistant structure forming material and the inlet support forming material and
- Figure 5 shows a variant of Figure 4 with a laser gun and a two-channel
- the invention is applicable with advantage everywhere where sliding bearings with a long service life require a certain inlet, e.g. in machines of the metallurgical industry, mill industry, food industry, engines, etc.
- a particularly preferred field of application are large engines, in particular two-stroke large diesel engines and in particular the piston rings cooperating with a cylinder liner and associated piston ring grooves.
- FIG. 1 shows a schematically indicated portion of a cylinder liner 1, in which an up and down piston 2 is arranged. This is provided with circumferential piston ring grooves 3, in each of which an associated, with its peripheral surface on the inside of the cylinder liner 1 abutting piston ring 4 is received.
- the piston ring 4 consists of a base made of cast steel 5 and has in the region of its opposite component, here the cylinder liner 1 side facing a wear-resistant structure 6, here in the form of an applied to the base part 5 protective layer. It would of course also be conceivable that the wear-resistant structure is already based on the base part.
- the wear-resistant structure 6 is circumferentially provided with a running surface of the cylinder liner 1 facing inlet support 7.
- the wear-resistant structure 6 consists, as can be seen from FIG. 2, of particles 9 of hard material embedded in a matrix 8.
- This may be ceramic material, such as tungsten carbide (WC) with a hardness of 3000 HV to 5000 HV act.
- a nickel alloy with phosphorus (P) and / or silicon (Si) is expediently provided. These materials are non-toxic, which allows their use also in the food sector.
- the nickel alloy can be 1 to 15% by volume, preferably 3.65% by volume P, 1 to 6% by volume, Preferably, 2.15 vol% Si and balance Ni.
- the volume fraction of the ceramic particles in the total volume of the wear-resistant structure 6 is greater than 60% and may preferably be up to 85%.
- the embedded ceramic particles 9 suitably have a spherical configuration with a diameter of 40 to 160 microns (microns).
- the thickness of the coating formed by the wear-resistant structure 6 can be adapted to the conditions of the individual case. In the case of piston rings of the type present here, the coating formed by the wear-resistant structure 6 can have a thickness of 0.2 to 2 mm.
- the radial surface of the wear-resistant structure 6 is comparatively rough and uneven, before attachment of the inlet support 7, as shown in FIG. This results in elevations 10 and between these located valleys 1 1, which would be detrimental to an inlet process.
- the applied to the wear-resistant structure 6 inlet support 7 therefore has the task to compensate for the roughness of the surface of the wear-resistant structure 6 and fill the valleys 1 1, so that towards the end of an inlet operation in Figure 2 indicated by a broken line 12 surface without protruding edges and corners. Since the valleys 11 are filled, also the valleys 11 laterally bounding, upwardly projecting hard particles 9 are reliably embedded in surrounding material, so that a breaking is not to be feared.
- the inlet support 7 makes a processing of the wear-resistant structure 6 unnecessary.
- low roughness In the production of the inlet support 7 results in a surface 13 with a direction indicated in Figure 2, low roughness. This is suitably 1 to 20 Ra. This roughness allows a gas-tight contact of the piston ring 4 at the associated running surface of the cylinder liner. 1 An additional processing is not required.
- the inlet support 7 may consist of any suitable inlet material, which is slowly removed during the running-in phase and disappears. In large engines such as two-stroke large diesel engines, as used for marine propulsion, the run-in period amounts to about 1000 to 2000 hours of operation.
- the thickness of the inlet support 7 is expediently 50 to 300 micrometers ( ⁇ m).
- the inlet pad 7 underlying inlet material should be much softer than the underneath, wear-resistant structure 6 and certainly not harder, preferably also slightly softer than the opposite sliding surface, here be the sliding surface of the cylinder liner 1.
- the inlet support 7 has a hardness of 100 to 200 HV.
- a metal containing copper (Cu) and / or tin (Sn) may be used.
- Cu copper
- Sn tin
- white metal which, in addition to copper and tin, also contains antimony (Sb) and / or zinc (Zn) with the proportions customary for white metal.
- the melting point of such materials is in the range between 600 and 900 ° C, which facilitates the coating process.
- the inlet support 7 can be provided with embedded, hard particles 14 as indicated in FIG. 3.
- it may expediently be ceramic particles, preferably with a spherical structure and with a diameter of up to 50 micrometers ( ⁇ m).
- the ceramic material Al 3 O 2 , CrO, Cr 3 C 2 or the like can be used.
- the proportion of hard particles 14 in the total volume of the inlet support 7 may be 5 to 30% by volume depending on the desired service life of the inlet support 7.
- the coating forming the inlet layer 7 is applied to the wearable structure 6 such that a metallurgical bond between the wear-resistant structure 6 and the inlet support 7 results in the boundary region.
- This metallurgical compound appears in the form of a boundary layer 15 indicated in FIG. 2 for the boundary region between the wear-resistant structure 6 and the inlet support 7, which is formed from elements of both adjoining layers.
- the boundary layer 15 is indicated only by a broken line.
- the barrier layer 15 may be formed by forming an alloy or causing a diffusion process. In the first case, the inlet support 7 to the wear-resistant structure 6 and this alloyed to the base body 5, and diffused in the second case.
- a boundary layer formed as an alloy zone or diffusion zone is formed, which is indicated only in FIG. 1 by a broken line.
- the boundary layer When alloying results in a comparatively large thickness of the boundary layer 15, which ensures a very good mutual connection. In many cases, however, very brittle crystals form in the boundary layer, which increases the risk of brittle fracture. This danger can be avoided by designing the boundary layer as a diffusion layer.
- a diffusion layer has only one of the diffusion depth corresponding thickness, which on the one hand, the volume fraction of brittle crystals is kept within narrow limits and on the other hand, the still ensures a good metallurgical connection.
- more or less energy is supplied during the application process.
- alloying both the coating material and an upper portion of the underlying material are melted. When diffusing, only the coating material is melted. The underlying material is heated, but remains in the solidified state.
- Ceramic material in the form of carbides can decompose at higher temperatures or convert into other carbides with other geometric shapes. If the hard particles 9 of the wear-resistant structure 6 are formed by carbides, the inlet support 7 is expediently applied to protect these carbides so that the wear-resistant structure 6 is not heated above the decomposition temperature of the carbides. The same naturally also applies to the application of the wear-resistant structure 6 to the base body 5. It is expedient for the heat transfer to be coated on the surface to be coated and for the coating material supplied to carry out a coating process to take place in such a controlled manner that only the coating material is completely coated melts and the underlying material remains completely in the solidified state, which then leads according to the above explanations to a Diffunsions Kunststoff.
- the coating operations may be carried out by spraying the coating material, melting the coating material or sintering the coating material.
- a heating spot which generates a heating spot and is relatively movable with respect to the surface to be coated.
- PTA Plasma Transfer Are
- the wear-resistant structure and the inlet support can be applied in separate operations or in a single operation. In any case, this can be done expedient in the same way, so that for applying a wear-resistant structure 6 forming coating and for applying the inlet support 7, the same device or an apparatus of the same design is or are used.
- the wear-resistant structure 6 forming coating and / or the inlet support 7 can, as already mentioned, be alloyed or diffused to the respective associated base.
- a melt forming a transition region is produced which contains both the constituents of the receiving layer and the layer to be applied thereto.
- both the applied material and a near-surface zone of the substrate are heated so far that a transition into the liquid phase takes place. For diffusing only the material to be applied is transferred into the liquid phase.
- Suitable devices are indicated in Figures 4 and 5.
- the wear-resistant structure 6 in the form of a coating applied to a base body 5 and the inlet support 7 in the form of a further coating on the wear-resistant structure 6.
- two energy sources arranged one behind the other are provided in the form of two laser cannons 16, 17 arranged one behind the other, each generating a laser beam 16a, 17a.
- a laser gun could also be a PTA (plasma transfer arc burner) burner and / or an induction coil or the like may be provided.
- Each energy source or each energy transmission beam is assigned a material supply device 18 or 19 which has a supply input 18a, 19a and effects a material supply to the energy transfer beam indicated as material transfer radiation 18b or 19b.
- the respective coating material can be supplied to the surface to be coated in the form of a round or square wire, a tape or in powder form.
- powdered material is to be processed.
- the supply devices 18, 19 are supplied via the inputs 18a, 19a with corresponding powdered material and emit a material flow 18b or 19b leading to powder material.
- the powder is suitably transported by inert gas, which protects against oxidation.
- the energy transfer beam 16a or 17a in the example shown in the form of a laser beam, a Walkerfleck is generated on the substrate to be coated.
- the respective assigned material transfer beam 18b or 19b is aligned so that the coating material is fed directly into the Schufleck or directly adjacent to this area.
- the supplied material is struck by the associated energy transmission beam and therefore, in the molten state, impinges on the respective associated substrate, which is likewise heated by the residual energy.
- the energy source 16 or 17 is adjusted so that the energy supplied is sufficient to melt both the coating material and a near-surface zone of the substrate.
- the energy source 16 or 17 is adjusted so that only the coating material melts completely and the respective associated base remains in the solidified state.
- the envisaged in Figure 4 energy sources 16, 17, each with associated material transfer means 18, 19 are arranged at a distance one behind the other. This distance can be chosen so that the wear-resistant structure 6 already is completely solidified before the inlet support 7 is applied or that the wear-resistant structure 6 is not yet solidified at least at the top, when the inlet support 7 is applied.
- both the wear-resistant structure 6 and the inlet support 7 by diffusion with connected to the respective associated pad.
- the abovementioned distance between the energy generating devices 16, 17 is therefore chosen so that the wear-resistant structure 6 that is initially produced is already completely solidified before the inlet support 7 is applied.
- the energy transfer is, as already mentioned above, controlled so that only the respective material to be applied is melted and the respective pad remains in the solidified state.
- a third energy transmission beam 20 is indicated, which is arranged downstream of the second energy transmission beam 17a.
- the downstream energy transmission beam 20 With the aid of the downstream energy transmission beam 20, only so much energy is transferred that the surface of the inlet support 7 is smoothed and made suitable for an intake process.
- the energy sources 16, 17 and the associated material feeders 18, 19 and the energy source beam generating the downstream energy source 20 are stationary. Accordingly, the base body 5 is moved to produce the desired coating according to arrow v. However, it would also be conceivable to arrange the base body 5 stationary and to move the coating devices. In this case, all power generation devices with optionally associated material supply means can be combined to form a uniformly movable assembly forming coating head.
- only one energy source 21 in the form of a laser gun is provided which generates an energy transmission beam 21a.
- This two material jets to form a first, the wear-resistant structure 6 forming coating and a second, the inlet support 7 forming coating is supplied.
- two material supply means may be provided.
- only one material feed device 22 is provided, which is designed with two channels. Accordingly, the material supply device 22 with two material inputs 22a and 22a 1 for the wear-resistant structure 6 forming material or the inlet pad 7 forming material is provided.
- the Materiaizucht Rhein 22 also generates two in the coating direction downstream of each other material transfer beams 22b, 22b 1 for the wear-resistant structure 6 forming or the inlet liner 7 forming material.
- the material transfer beams 22b, 22b ' are positioned so that first the material transferring beam 22b forming the wear-resistant structure 6 impinges on the not yet coated surface of the base body 5 and subsequently the material transferring beam 22b' forming the infeed support 7 hits the upper side of the beam 22b already generated, wear-resistant structure 6 impinges.
- the distance between the beams 22b, 22b ' may be so low in the present case that the already applied, the wear-resistant structure 6 forming layer can still deliver enough energy to melt the material applied to form the inlet support 7 material.
- a trailing energy transfer jet 20 can also be used, as in the embodiment according to FIG. With respect to the construction as a unitary assembly or the movement of the base part 5 or coating head also applies the same as above.
