Definitions

  • the invention relates to an ink transfer roller one introduced mechanically or by lasering Surface structure made of color transfer cells in one microporous, metallic or ceramic or metal-ceramic hard material layer, as well as a process their manufacture.
  • Such an ink transfer roller is for example known from DE 40 07 130 A1.
  • These are in one embossed metallic surface wells, and one with it resulting burr removed and the well surface is with hard materials, e.g. with hard chrome or with Silicon carbide granules, in a nickel matrix, for Increased abrasion resistance galvanically coated.
  • hard materials e.g. with hard chrome or with Silicon carbide granules, in a nickel matrix, for Increased abrasion resistance galvanically coated.
  • a thin layer of hard chrome can be applied be applied.
  • these upper layers are always with fine micro cracks and fine pores with micrometer dimensions especially at the limits of determine stored hard material grains, whereby only their liability is limited.
  • Ink transfer roller it is an object of the invention, the one mentioned above Ink transfer roller to improve that a longer service life, less wear and tear has less susceptibility to corrosion.
  • the solution is that superficial micro cracks and pores through one with a high voltage plasma Applied ion implant material are closed.
  • All previously known microstructured ink transfer rollers are suitable for the treatment of the Surface with implant material, both at the New production as well as for post-treatment.
  • the at the Material layers applied during implantation have a too the cell dimensions comparatively small thickness of 1 - 2 ⁇ m, so that the cell volume is practically unchanged remains.
  • the implantation of the metellions takes place in one Nitrogen atmosphere, so that the metals partly as Combine nitrides and very hard crystallines Form structures.
  • Another abrasion-resistant top layer of is advantageous 0.05 - 1 ⁇ m, preferably 0.1 ⁇ m thickness from a hard material implanted in a similar manner. They are hard metal oxides or nitrides provided. Zirconium oxide (Zr02) has especially proven, for which the implantation in an oxygen plasma is made. This top layer will especially chosen so that a desired surface affinity to the to be transported and dosed Printing ink is created.
  • Zr02 Zirconium oxide
  • the surfaces tempered in this way show a higher hardness of 1400 - 166 HV compared to that of the colored particles that are under 1200 HV.
  • the untreated chrome surfaces have a hardness of 600 - 800 HV, and surfaces from Ceramics have a hardness of 900 - 1000 HV. You are lying i.a. under which the color particle and it occurs constant wear and tear.
  • the implantations are carried out under high voltage with a turbulent flow of the plasma preferably in nitrogen and / or oxygen.
  • tension will be a thousand to ten thousand volts applied, and the amperage becomes like this chosen that with moderate heating a sufficient Penetration depth of the ions and anchoring of the Implant in the surface is done without this burn or destroy thermally.
  • a gas pressure of approx. 1 mbar has proven to be favorable proven.
  • the impact voltage of the ions is preferred in the range between 600 V and 2 kV.
  • the operating heat is controlled accordingly Current and high voltage so low that no noticeable thermal stresses after cooling arise in the near-surface layer. There are Temperatures of 50 - 80 ° C are provided. Therefore can also such novel rollers according to DE 44 26 485 Implant, the hard material layer of a plastic substructure is worn. Esp. is the Hard material layer over a metal layer on one elastic plastic jacket is applied, which with Plastic fiber inserts made of reinforced plastic and with an elastic base on a solid metallic roll core is interchangeably mounted.
  • Figure 1 shows an enlarged plan view of a Detail of the surface of a roller 1 in a predetermined grid R with truncated pyramid-shaped cups N is provided.
  • A remains between the wells small bridge S and the inclined walls W itch in a flat floor B.
  • Figure 2 shows a thousand times magnification of a small one Section of the wall W and the bottom B of one Cup N, which is made of a hard material HS, e.g. Stole, existing structure through a micrometer-thick doping with an ion implant material H and one overlying top layer D is provided.
  • a hard material HS e.g. Stole
  • H ion implant material
  • Figure 3 shows an enlarged cross section in the Roll surface into it, the well N in known Way with an oxidic hard material HS from a There is a nickel matrix with a carbide insert on one Hard chrome layer is applied. The chrome surface is then by ion implantation with the implant material H and the top layer D.
  • Figure 4 shows an enlarged surface of the Hard material layer HS, which is provided with hard chrome. It clearly show the grain boundaries, which are small Form microcracks M. These micro cracks are caused by the High voltage implant closed.
  • Figure 5 shows another type of the known Roller surfaces in high magnification.
  • a ceramized surface made of chromium oxide for example provided with a well N by lasering.
  • the Laser beam is guided from well to well and melts the material with high energy and evaporates part of the same, so that the well N are formed.
  • they are Crater edges solidified unevenly from the melt, and many microcracks M are visible there.
  • microcracks are sufficient M to a great depth relative to the well structure solidified well surface. These micro cracks M are filled with the implant H.
  • the top layer D is shown, in particular the compatibility the color with the surface influenced favorably and you have a given adhesion to the ink gives.
  • the strengths of layers H and D are excessive shown.
  • Figure 7 shows one from left to right at an angle Deep grinding of a lasered Hard material layer HS. It can be seen that the microcracks M also in the low-lying areas about radially from extend the N cup. These micro cracks are going through the ion implantation filled and sealed. Furthermore gives the implant material H, D a relatively smooth Cell surface.
