Definitions

  • the invention also provides the method of manufacturing a razor blade wherein at least a cutting edge is coated with a metal, metallic compound or an alloy containing a metal or metallic compound, and the initial coating is thereafter provided with a coating of a different metal, metallic compound or alloy containing a metal or metallic compound or with a silicon compound.
  • Examples of materials which may be used for this initial coating are chromium, platinum and other noble metals including iridium, osmium, palladium, rhodium and ruthenium, titanium, zirconium, vanadium, niobium, tantalum, molybdenum, cobalt, nickel, manganese, rhenium and tungsten, as well as alloys of any of the foregoing.
  • the second coating is then provided with a coating of a polymer which improves the shaving properties of the blade and may, for example, comprise a fluorocarbon polymer, for example polytetrafluoroethylene, or a copolymer of thio-carbonyl fluoride and tetrafluoroethylene.
  • a fluorocarbon polymer for example polytetrafluoroethylene
  • a copolymer of thio-carbonyl fluoride and tetrafluoroethylene for example polytetrafluoroethylene
  • molybdenum plated targets with a residual atmosphere of nitrogen at a pressure of, for example, l to 4 X 10" millimetres of mercury, to form a molybdenum nitride coating.
  • the coatings may be produced by chemical vapour deposition or by reactive evaporation.
