Definitions

the invention relates to an ink transfer roller with a mechanically or by laser surface structure made of ink transfer cups in a microporous, metallic or ceramic or metal-ceramic hard material layer, and a method for the production thereof.
Such an ink transfer roller is known for example from DE 40 07 130 A1.
wells are embossed into a metallic surface, and a burr which arises is removed, and the well surface is covered with hard materials, e.g. with hard chrome or with silicon carbide grains, in a nickel matrix, galvanically coated to increase the abrasion resistance.
hard materials e.g. with hard chrome or with silicon carbide grains, in a nickel matrix, galvanically coated to increase the abrasion resistance.
a thin layer of hard chrome can be applied.
these upper layers are always traversed by fine microcracks, and fine pores with micrometer dimensions are found, in particular at the boundaries of the embedded hard material grains, as a result of which there is only limited adhesion thereof.
inking rollers are known, the cells of which are lasered into a plasma-sprayed hard ceramic layer, for example chromium oxide (Cr203).
Cr203 chromium oxide
the solution is that superficial microcracks and pores are closed by an ion implant material applied with a high-voltage plasma.
a method according to the invention for treating the known rollers for plasma-assisted implantation of the closure material is specified in claims 13 to 17.
All previously known microstructured ink transfer rollers are suitable for the treatment of the surface with implant material according to the invention, both in the case of new production and for post-treatment.
the material layers applied during the implantation have a thickness of 1 to 2 ⁇ m, which is comparatively small compared to the cell dimensions, so that the cell volume remains practically unchanged.
Combinations of tetravalent substances with heavy metals have proven successful as substances for filling and closing the cracks and pores.
heavy metals in particular the tetravalent titanium and the hexavalent molybdenum in a weight ratio of 70/30 to 90/10, preferably 80/20, have proven successful as substances for filling and closing the cracks and pores.
These metal ions penetrate deep into the interior of microcracks and the boundary layer, which often occur at the grain boundaries of electrolytically applied layers or in sputtered layers or after lasering.
the closure and the filling of the cracks provides especially an increase in corrosion resistance, since the surface becomes smooth and dense.
the implantation of the metal ions takes place in a nitrogen atmosphere, so that the metals combine with it in part as nitrides and form very hard crystalline structures.
Another abrasion-resistant cover layer of 0.05-1 ⁇ m, preferably 0.1 ⁇ m, of a hard material is advantageously implanted in a similar manner. Hard metal oxides or nitrides are provided for this. Zirconium oxide (Zr02) has proven particularly useful, for which the implantation is carried out in an oxygen plasma. This cover layer is chosen in particular in such a way that a desired surface affinity for the printing ink to be transported and dosed arises.
the surfaces tempered in this way show a higher hardness of 1400 - 166 HV compared to that of the paint particles, which is below 1200 HV.
the untreated surfaces of chrome have a hardness of 600 - 800 HV, and surfaces of the ceramics have a hardness of 900 - 1000 HV. They are therefore generally under that of the paint particles, and there is constant wear.
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 are applied, and the current strength is selected so that, with moderate heating, a sufficient penetration depth of the ions and anchoring of the implant takes place in the surface without burning or thermally destroying it.
a gas pressure of approximately 1 mbar has proven to be favorable.
the impact voltage of the ions is preferably in the range between 600 V and 2 kV.
Such novel rollers according to DE 44 26 485 can also be coated with an implant, the hard material layer of which is supported by a plastic substructure. Esp. the hard material layer is applied over a metal layer on an elastic plastic jacket, which consists of plastic reinforced with plastic fiber inserts and is interchangeably mounted on a solid metallic roller core with an elastic substructure.
Figure 1 shows an enlarged plan view of a section of the surface of a roller 1, which is provided in a predetermined grid R with truncated pyramidal cups N.
a small web S remains between the wells and the inclined walls W end in a flat bottom B.
Figure 2 shows a thousandfold enlargement of a small section of the wall W and the bottom B of a well N, which is made of a hard material HS, e.g. Steel, existing structure is provided by a micrometer-thick doping with an ion implant material H and an overlying cover layer D.
a hard material HS e.g. Steel
H ion implant material
an overlying cover layer D ion implant material
the hard material HS is very badly destroyed in its structure by the mechanical processing and has a high surface roughness and porosity, although the surface has been electrolytically polished before the ion implantation.
the layer thicknesses of the implants H, D are shown exaggerated; in particular, the implanted oxide cover layer D is generally much thinner than the nitrified metallic implantation H.
Figure 3 shows an enlarged cross section in the Roll surface into, the well N consists in a known manner with an oxidic hard material HS from a nickel matrix with carbide insert, on which a hard chrome layer is applied. The chrome surface is then provided with the implant material H and the cover layer D by the ion implantation.
FIG. 4 shows an enlarged surface of the hard material layer HS, which is provided with hard chrome.
the grain boundaries, which form small microcracks M, are clearly shown. These micro cracks are closed by the high voltage implant.
Figure 5 shows another type of the known roller surfaces in high magnification.
a ceramicized surface for example made of chromium oxide, is provided with a N cup by lasering.
the laser beam is guided from well to well and melts the material with high energy and evaporates part of it, so that the wells N are formed.
the crater edges have solidified unevenly from the melt, and many microcracks M are visible there.
the microcracks M extend into a deep depth of the solidified well surface relative to the well structure. These microcracks M are filled with the implant H.
the cover layer D is shown on the implant H, which in particular has a favorable influence on the compatibility of the color with the surface and gives it a predetermined adhesion to the printing ink.
the strengths of layers H and D are shown exaggerated.
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 extend approximately radially from the wells N in the lower regions. These microcracks are filled up and sealed by the ion implantation. In addition, the implant material H, D results in a relatively smooth cell surface.
