Definitions

  • This invention is related to forming a preform using high wear resistant particles and thus a method of producing a wear resistant composite component.
  • wear resistance is provided by placing wear resistant supports only on the zones of the relevant parts which are exposed to wear. Wear resistance is provided by placing a preform on these zones.
  • the preforms which are composed of high wear resistant particles are prepared by utilizing an organic or an inorganic binder and with a specific thickness restriction. These preforms of the relevant parts are placed with certain interval restrictions on the zones exposed to wear and later wear resistant components are produced by means of casting.
  • the quantity of the binder should be limited because the residue of the used binder decreases the cohesion formed between the support material and the matrix. Therefore, the quantity of the binders used for preparing preforms is restricted.
  • Another problem of the preforms prepared by using a binder is that the support phase ratio cannot be adjusted as desired.
  • the preforms are placed at a certain distances to each other and parallel to the wear surfaces will continuously change the wear rate of the component.
  • the objective of this invention is to develop preforms from wear resistant materials without using any binders.
  • Another objective of this invention is to produce a wear resistant composite component by placing preforms on the zones of the wear resistant components which are exposed to wear.
  • Another objective of this invention is to ensure the placement of the preforms in such a way that the component wear rate is constant through the wear zone.
  • Figure 1 - is a general view of the container.
  • Figure 2 - is a view of an alternative embodiment of the container.
  • Figure 3 - is a view of an alternative embodiment of the container.
  • Figure 4 - is a cross-section view of the composite component.
  • Figure 5 - is a flow diagram of the method of producing composite components in which there are high wear resistance particles.
  • a preform (2) or preforms (2) which comprise high wear resistant particles (4) are placed on the zones of the wear resistance components which need to be wear resistant.
  • the inventive composite component (3) comprises a preform (2) which is used in the production method, high wear resistant particles (4) which are placed on zones that need to be wear resistant, which are brought together without an organic or an inorganic binder, and a container (1) wherein the particles (4) are placed.
  • This preform (2) is developed by bringing together high wear resistant particles (4) without using any binders.
  • the wear resistant of the high resistant particles (4) could be wear resistant oxides, carbides, nitrides etc. or a mixture of these at a certain ratio.
  • a container (1) which is made of any material which does not reduce the wear resistance of the component by leaving any residue.
  • the container (1) is a structure wherein high wear resistant particles (4) are trapped and it is a chamber which allows molten metal to infiltrate into itself.
  • the container (1) is made of a metallic or a non-metallic material and it could be composed of any kind of material which ensures wear resistant components to remain in the relevant zone and in the desired form until solidification is complete.
  • the container (1) should allow the liquid metal to go it and infiltrate through the wear resistant particles and also to melt away in such a way that it does not decrease the wear resistance of the components or their performance after the casting process over.
  • the container (1) in which wear resistant particles (4) are placed in accordance with the material to be used in the formation of the container (1), could have a perforated or a porous structure.
  • the objective here is to enable the molten metal to go into the container and infiltrate through the wear resistant particles (4).
  • All the surfaces of the container could either be closed or it could have at least one open surface ( Figure 1, Figure 2 and Figure 3).
  • a preform (2) is developed by placing high wear resistant particles (4) inside the container (1) freely by calculating the ratio between the main body and the wear resistant particle (4).
  • This preform (2) is placed on zones that need to have wear resistance during the production stage in such a way that the abrasion rate remains constant at the relevant zone.
  • a preform (2) is developed by placing high wear resistant particles (4) inside the container (1) (101).
  • the preform (2) which is developed by placing high wear resistant particles (4) inside the container (1) is placed inside a mould in order to obtain a wear resistant composite component (3) with a metallic matrix (102).
  • a formation of continuity by the preform (2) in the abrasion direction is ensured.
  • the shape of the preform (2) could be any as desired. This flexibility ensures production convenience.
  • molten metal is poured into the mould (103). The molten metal at a specific temperature infiltrates the high wear resistant particles (4) present inside the container (1) by melting the container (1) (104).
  • the material which forms the container (1) during casting process melts away without leaving behind any residue by being mixed with the molten metal infiltrated into the high wear resistance particles (4) (105).
  • the cast product taken out of the mould after the casting process is complete, is a wear resistant composite component (3) ( Figure 5) with a metallic main structure wherein high wear resistant particles (4) are present.
  • a wire mesh or a perforated plate made of stainless steel is used to make containers (1).
  • the process of bringing together wear resistant particles without using any binders is ensured. Furthermore, the wear resistant particles (4) are placed in such a way that the wear rate remains constant during operation.
