Definitions

  • the invention pertains to a wear component in a laminar structure, and, more particularly to a wear component, in a laminar structure to which is applied, a fluid or a webbed material such as machine clothing.
  • Wear components in a laminar structure are used in high-pressure pistons of fluid pumps with a liquid fluid, in high-vacuum pumps with a gas or a mixture of gases, for precision guidance in machine tools and production facilities or as a drainage strip in paper or cardboard machines with the medium of a webbed material in the form of machine clothing.
  • the bonded systems are generally produced from sintered ceramic segments that are gummed together or gummed to at least one beam part.
  • the interconnection to the beam is often additionally secured either mechanically or by an adhesive, the connection may also be by way of at least one dovetail groove and, if necessary, with additional screwed joints.
  • the ceramic materials that are used are usually made out of oxides, carbides or nitrides.
  • oxides such as, the SiC, Si 3 N 4 , Al 2 O 3 , ZrO 2 material groups with various stabilizers, MgO, Y 2 O 3 , rare-earth oxides or even multiphase ceramic mixtures made from these compounds.
  • Wear protection layers such as wear reducing coatings formed on substrates is used, which do not lead to any corrosion due to its properties.
  • the wear protection layers are frequently applied by a thermal spray coating process, since this represents an economical production method, which is not subdivided into segments. According to well-known technique, which, for example, is described in detail in PCT applications WO 96/05370 A1 and WO 96/24717 A1 and in U.S. Pat. Nos. 4,331,511; 3,446,702; 3,778,342; 3,352,749 and 3,351,524.
  • oxides for example Al 2 O 3 , Cr 2 O 3 , ZrO 2 , SiO 2 or TiO 2 , carbides such as WC or TiC, Al- and/or Zr-silicates, borides, for example TiB 2 , Ti 2 B, ZrB, ZrB 2 or ZrB 12 or mixtures of the aforementioned materials or material classes are used.
  • a well-known disadvantage of these components, having an applied wear protection layer, is that the limited layer thickness is a maximum 0.5 mm. This limitation is due to the lack of good adhesion resulting from large residual stress within the layers and since there is no mechanical and thermo physical compatibility with the facilitated substrate. As a result the wear cannot be stopped, just slowed. Due to this, the wear components in paper or cardboard machines are inspected, depending on the field of operation, at regular intervals. Another problem, not yet satisfactory resolved at this point, is the porosity of thermally sprayed wear protection layers, which leads to reduced life and increased wear on the machine clothing in a paper or cardboard machine.
  • the present invention has a higher mechanical capacity and allows for more simple handling. Further, it does not contain any segment structure, which results in low wear on the wear component itself and on the medium, particularly at the machine clothing, which may be in the form of a sieve or felt in a paper or cardboard machine.
  • the present invention allows for increased geometric freedom of design and that it is more economical in terms of material costs.
  • the second task of the invention is to provide a procedure for the production of a wear component in a laminar structure, which results in a high process certainty, a high production efficiency, high throughput performance and low ongoing procedure costs.
  • the first task, in accordance with an embodiment of the present invention is resolved for the wear component in a laminar structure in that the wear component in a laminar structure is formed from one beam.
  • the beam being made out of high-grade steel and/or copper and/or nickel and/or pressure die-cast aluminum and/or zinc, and/or at least from one of their alloys.
  • the beam may be made from a plastic beam with at least one inserted plate made out of high-grade steel and/or copper and/or nickel and/or aluminum and/or zinc and/or at least from one of their alloys.
  • the wear component in the laminar structure has an infeed area with an infeed angle for a medium of ⁇ 90°, preferably ⁇ 45°.
  • At least one partial surface of the wear component in the laminar structure that is subject to wear has at least one low-wear layer, made from a material of the class of the self-fluxing alloys and that the low-wear layer was re-melted thermally.
  • This wear component in a laminar structure does not contain any disadvantageous segment structures. Due to the thermal re-melting process there is a diffusion connection between the beam part (basic material) and the applied low-wear layer (wear protection layer) with improved bonding strength in comparison to other thermal spray layers. This provides a higher mechanical capacity, allowing for simple handling and results in a reduced wear on the medium, particularly to the machine clothing, which may be in the form of a sieve or felt in a paper or cardboard machine. Moreover, the geometric freedom of design provides for the opportunity to realize, in the infeed area of the drainage elements in a paper or cardboard machine, infeed angles of ⁇ 60°, which results in improved drainage performance.
  • the low-wear layer is preferably made out of a self-fluxing alloy, such as, NiCrB, NiCrBSi, CoNiCrBSi, mixtures of these alloys or another self-fluxing alloy.

  • the low-wear layer has a hardness HU 1.0 from 3,006 N/mm 2 to 15,000 N/mm 2 , preferably from 5,000 N/mm 2 to 10,000 N/mm 2 , a layer hardness H plast from 5,000 N/mm 2 to 30,000 N/mm 2 , preferably from 5,500 N/mm 2 to 20,000 N/mm 2 , and/or a layer hardness HV 0.1 from 650 to 5,000, preferably from 700 to 2,500. These parameters provide a selection of wear reducing and minimizing data and can be realized separately or in combination.
  • the firmness and the technical wear properties of the wear component is further improved if the low-wear layer is applied to the surface areas, which border a partial surface that is subject to wear, particularly at the infeed area.
  • the complete infeed area is coated including all areas associated with the infeed angle and the drainage strip, in a paper or cardboard machine.

  • a plastic beam may be utilized with at least one inserted plate made out of high-grade steel and/or copper and/or nickel and/or aluminum and/or zinc and/or at least one of their alloys, so that at least one partial surface of the wear component in a laminar structure, that is subject to wear, has at least one low-wear layer.
  • the low-wear layer being made from material of a self-fluxing alloys, which was added by a thermal spray coating process and the low-wear layer is thermally re-melted.
