Definitions

  • refiners are used in the paper and / or pulp industry, with the aid of which pulp and / or pulp as well as rag and recycled material can be ground.
  • the refiners require a tool, namely a grinding tool which, depending on the refiner configuration, is designed, for example, as a cone refiner or disc refiner as a cone or disc or segment.
  • a tool namely a grinding tool which, depending on the refiner configuration, is designed, for example, as a cone refiner or disc refiner as a cone or disc or segment.
  • These elements are subject to very high wear. For this reason, attempts have always been made to increase the stability of such tools. For this reason, great attention has been paid to the choice of materials and therefore such tools, for example made from acid-resistant steels and / or cast materials. Steel tools are hardened, for example, at least on the stressed surface.
  • the invention is based on the object of creating or proposing a grinding tool and a method by means of which the treatment of the refiner can be made stable with a long-lasting effect by means of targeted treatment.
  • This object is achieved with a refiner according to the invention in that firstly foreign ions with a penetration depth of up to 500 ⁇ m are embedded in the surface of the active surface of the tool by means of a plasma-assisted method and an additional hard material layer is attached to the surface. Foreign ions are deposited by accelerated ions with defined energy. The foreign ions to be implanted are placed in a reactive plasma in the
  • the number of foreign ions implanted and their penetration depth can be varied by corresponding concentrations of the foreign ions, ie the number of implanted foreign ions and their penetration depth can be precisely determined and depends on the materials used and the energy of the foreign ions.
  • Such a procedure has advantages in that only a few parameters have to be taken into account in the process, namely the foreign ion dose, the particle energy and the bombardment time. The process is therefore very easy to control and the result is easily reproducible.
  • a hard material layer is added, which results in the additional advantage that the surface structure is compressed.
