Definitions

  • ABSTRACT A writing nib, more especially for drawing pens comprises a tube which is coated by a cathodic sputtering.
  • One aim of the invention is therefore that of constructing the writing nib tube of the tip of a pen in such a manner that it can be produced more cheaply and has the high length of life aimed at.
  • the invention provides a nib tube of the above-mentioned construction which is characterised in that the tube is provided with the surface layer by means of cathodic sputtering.
  • This method of cathodic sputtering which provides the possibility of providing on practically any material a thin film of practically any desired material has been found highly advantageous for reinforcing the nib tube.
  • This method it is possible to coat all the surfaces subjected to mechanical loading with a layer of the desired thickness which has a long period of life. It is not only the end annular face of a nib tube which slides on the material written or drawn on, but also the external peripheral face of the tube, which is slid along a tin plate or a ruler, which is subjected to wear. In this respect there is an increased amount of wear, especially when the edge, along which the tube is passed, is provided with marks, such as millimeter marks, which have a saw-like action.
  • metallic carbides especially titanium carbides or tungsten carbides for forming a surface layer.
  • a preferred layer thickness lies between 3 and 7 microns.
  • the surface layer can also consists of metal oxides, metal sulfide, or monocrystals, more especially molybdenum sulfide, applied in the same manner.
  • writing tubes reinforced in this manner are superior to all known writing tube nibs with a coating, and also superior to writing tube nibs which have a compaction of the material brought about at the writing tip by pressing.
  • the length of life of the writing tubes in accordance with the invention corresponds approximately to that of conventional writing nibs with insertion bodies made up of moncrystals etc., without having their disadvantages, which are due to the brittleness and the high price.
  • the surface layer owing to the method used, is thickest at the end annular face of the tube, which serves for writing or drawing but it is also present on the external periphery of the tube and on its inner periphery. It is convenient to provide the cleaning wire with such a superficial layer.
  • the coating is preferably carried out separately before the coating of the writing tube nib.
  • the surface layer of the writing tube nib has several layers applied to it by cathodic sputtering.
  • These layers consist of different materials, and for example the first layer can consist of a material which prevents oxidation so that as a basic material cheaper materials can be used and it is not absolutely necessary to use stainless steel.
  • a further layer can ensure the mechanical wear resistance aimed at.
  • This layer can be made porous, something which is advantageous as regards writing characteristics. The porosity does not, however, in this case have any disadvantageous effect as regards possible oxidation of the surface lying underneath, because the first layer is resistant to corrosion.
  • the writing tube nib 10 mounted in the writing tip can consist of any suitable materials including nonnoble metals or even plastic. It carries a surface layer 14 on the front end annular face of the tube 10 and has a coating 16 on the outer surface of the tube and a coating 18 on the inner bore surface of the tube. This coating l4, 16, 18 is applied by cathodic sputtering. Owing to the method the coating 14 is thicker on the end annular face than the coating l6, 18 on the outer surface and the inner bore surface.
  • the sliding cleaning wire 12, arranged inside the tube nib 10 also has a layer coating 20, which is applied by cathodic sputtering.
  • the coating is, however, not carried out within the writing tube nib l0.
  • a method for providing a mechanical wear resistant surface layer on a nib tube for a drawing pen in which the nib tube is provided with an end surface and with side surfaces that extend away from the end surface comprising applying to the nib tube by cathodic sputtering a layer of wear resistant material in which the cathodic sputtering step is performed a plurality of times, with each performance thereof producing asucceeding surface layer of a material over the proceeding surface layer of a different material, thereby forming a plurality of surface layers applied by cathodic sputtermg.
