Definitions
- the invention relates to a method for producing a hard material coated metal component comprising the steps of preparing a release agent, adding the processed release agent to a powder mixture, providing the powder mixture, providing the substrate of metal, heating the powder and the substrate in a heater a layer on the substrate, wherein the layer has a higher hardness than the substrate, and cooling the substrate, and a metal component having a hard material layer.
- Link chains each with a chain link interconnected chain links are in various forms in use.
- the area of the chain links is stressed so much that there is a need for a wear-resistant bearing surface.
- it is useful, in particular with regard to high volumes, to replace expensive solutions with cost-effective coating methods and processes.
- DE 10 2005 047 449 A1 presents a wear-improved link chain whose chain pins or chain sleeves are provided with hard material coatings. These coatings are applied by PVD (PVD: Physical Vapor Deposition).
- the hard material layer has a thickness of 1 to 10 ⁇ m and may further be coated with a sliding layer, e.g. PTFE, be surrounded.
- the document DE 10 2006 052 869 A1 describes a link chain whose joint surface of the bolt and the sleeve is provided with a PVD hard material layer.
- bolt and sleeve made of a high-carbon steel with a carbon content between 0.4 wt .-% and 1, 2 wt .-%.
- DE 10 2011 006 294 A1 presents a method for producing a hardened coated metal component.
- the metal component is heat treated to enrich carbon and / or nitrogen in the surface layer and then quenched to a temperature below that of martensite formation. Then, the metal component is tempered to a higher temperature than the temperature at which the subsequent coating process takes place.
- the coating itself is carried out by CVD or PVD (CVD: Chemical Vapor Deposition).
- DE 10 2016 215 709 A1 shows chain components such as sleeves, lugs, bolts and rollers made of steel, which are provided with a wear-reducing CrN layer.
- the CrN layer is produced by a CVD method.
- the nitrogen is obtained from the optionally nitrided steel before the treatment.
- a joint for a roller or sleeve chain is presented in WO 2014019699 A1.
- a nitridic or carbide hard coating is applied to the joint by PVD or CVD techniques.
- PVD processes require a working pressure of 10-4 to 10 Pa and are operated at operating temperatures of several hundred ° C, depending on the type of coating. PVD processes thus place high demands on the coating chamber. In addition, they are not suitable for bulk goods.
- Substrate and material to be deposited (target) are spatially separated in the coating chamber. PVD processes are so-called visual line processes, ie only the surfaces visible from the target are coated. Internal surfaces or holes are thinner coated. In the case of the powder processes, on the other hand, there is the problem that the diffusion of carbon into the hard material layer leads to the formation of carbides.
- nitrides and in particular chromium nitride, promises significantly better service lives of the component in terms of wear, it is necessary to improve the formation of nitrides, especially in the near-surface regions. This achieves the solutions presented in the prior art in any way.
- the object of the invention is achieved by a device according to claim 1.
- the chain component according to the invention of a chain for transmitting a force is coated with a hard material layer.
- the chain component comprises a steel-based substrate and a hard material layer on an outside of the substrate.
- the hard material layer is formed to have metal nitrides.
- the mass concentration of carbon (C) in the hard material layer decreases toward the outside of the hard material layer.
- CVD Chemical Vapor Deposition
- CVD Chemical Vapor Deposition
- the hard material layer also increases the Corrosion resistance.
- carbon-containing steels may be suitable as a substrate, since these steels have sufficient strength and tempering resistance.
- the hard material layer can consist of both metallic and non-metallic hard materials. Suitable metallic hard materials are all carbides, nitrides, carbonitrides, borides and silicides of the transition metals, for example chromium, tungsten, zirconium, titanium.
- Diamond and DLC Diamond Like Carbon
- boron carbide cubic boron nitride, silicon carbide or aluminum nitride are suitable as non-metallic hard materials.
- metallic nitride formers in particular chromium nitride (CrN)
- CrN chromium nitride
- Chromium nitride has several advantages over other metallic and non-metallic hard materials.
- chromium nitride can be deposited by means of CVD and, with good adhesion to the substrate, a thin layer of hard material with a layer thickness of at least 1 to 5 ⁇ m produces high wear resistance.
- the CVD method offers advantages over the PVD method known from the prior art for producing a hard material layer.
- the CVD process is bulk material-compatible with respect to the PVD process and offers economic advantages in terms of plant technology, operation and process technology:
- the substrate to be coated is mixed, for example in a rotary drum with nitrogen-containing powder.
- the coating process takes several hours at a certain process temperature and pressure. All accessible surfaces of the substrate are evenly coated, even tight holes.
- the coated substrate is cooled.
- the coating is carried out by evaporation of the material to be deposited at working pressures of 10 4 to 10 Pa.
- the hard material layer is designed so that it consists essentially of CrN. It has on the surface of the component an outer side (outer side) and an inner side in contact with the substrate. Due to the use of carbon-containing steels as a substrate, the carbon diffuses out of the steel into the hard material layer at the high process temperatures and forms there CrNC and / or CrC.
- the hard material layer is formed such that the C mass concentration on the outside of the hard material layer is lower than on the inside. As a result, the wear resistance and thus the life of the chain component according to the invention is significantly increased. Furthermore, the hard material layer has on its outer side a significantly higher metal nitride content, which leads to an improvement in the wear resistance compared to a hard material layer of metal carbides.
- the mass concentration of the nitrogen on the outer surface of the hard material layer is greater than the mass concentration of the carbon.
- the ratio of the mass concentrations of nitrogen to carbon is greater than 3: 1, more preferably greater than 5: 1.
- the C mass concentration in a region close to the substrate in the direction of the outside of the hard material layer increases in the hard material layer, the C mass concentration in a region close to the substrate in the direction of the outside of the hard material layer.
- the C mass concentration has a maximum in the hard material layer.
- the distance of the maximum of the C mass concentration in the hard material layer to the outside of the hard material layer is smaller than the distance of the maximum of the C mass concentration in the hard material layer to the boundary between the hard material layer and the substrate.
- the amount of slope of the C mass concentration in the hard material layer in a region close to the substrate is higher than the amount of the slope in a region of decreasing C mass concentration.
- the C mass concentration steeply increases in a region near the substrate. As a result, a large part of the carbon available in the hard material layer is bound in a large depth of the hard material layer.
- the mass concentration of nitrogen (N) in the hard material layer increases in the direction of the outside of the hard material layer.
- the outside of the hard material layer therefore has a higher proportion of CrN than deeper regions.
- the slope of the N mass concentration in the hard material layer in a region close to the substrate is higher than the slope in a region near the outside of the hard material layer.
- the N mass concentration of the hard material layer therefore has a maximum value near the surface of the substrate.
- the mean N mass concentration in the hard material layer is greater than the average C mass concentration in the hard material layer.
- the N mass concentration can advantageously be increased by suitable process parameters, for example by nitriding the substrate or / and by using a nitrogen-containing powder.
- the average N mass concentration in the hard material layer is greater than the mean C mass concentration in the hard material layer by a factor of 2, preferably by a factor of 3 and more preferably by a factor of 4. This design ensures that the hard material layer is built up to a large extent from CrN.
- the average N mass concentration in the near-surface region of the hard material layer at each depth is greater than the average C mass concentration in the hard material layer.
- carbon of the carbonaceous steel substrate accumulates. This carbon enrichment leads to the formation of carbides, mainly iron and chromium carbides.
- the near-surface region comprises a depth of up to 50% of the layer thickness, preferably 65% of the layer thickness and particularly preferably up to 80% of the layer thickness.
- the average mass concentration of chromium (Cr) in the hard material layer is greater than the average mass concentration of iron (Fe) in the hard material layer.
- Cr is predominantly incorporated into the hard material layer by the coating process, e.g. by a Cr, Fe-containing powder during the CVD process.
- the Fe contained in the hard material layer improves the adhesive properties of the hard material layer on the substrate and prevents flaking.
- the average Cr mass concentration in the hard material layer is greater than the mean Fe mass concentration in the hard material layer by a factor of 2, preferably by a factor of 4 and more preferably by a factor of 6. To the adhesive properties of the hard material layer on the substrate too improve, suffice small amounts of Fe in the hard material layer or the diffusion layer.
- the average Cr mass concentration in the near-surface region of the hard material layer at each depth is greater than the mean Fe mass concentration in the hard material layer.
- the near-surface region comprises a depth of up to 50% of the layer thickness, preferably 65% of the layer thickness and particularly preferably up to 80% of the layer thickness.

- the bolts 1 1 of the outer chain link 14 are rotatably mounted in the sleeves 12 of the inner chain link 13, whereby the connection in each case form a chain link of the chain 10.
- the bolts 1 1 of the chain 10 are made entirely of a carbon-containing steel, wherein the joint surface of the bolt 1 1 is provided with a deposited in a CVD process CrN hard material layer.
