Wilkinson Sword 'Limited , 16 Pall Mall, London SV/ 1», Rasierklinge und Verfahren zu ihrer Herstellung Wilkinson Sword 'Limited, 16 Pall Mall, London SV / 1' , razor blade and method of making it
Die Erfindung besieht sich auf eine Rasierklinge und .auf ein Verfahren zu ihrer Herstellung.The invention relates to a razor blade and a method for making the same.
Gemäss der Erfindung wird eine Rasierklinge geschaffen, die mindestens in der Oberfläche ihrer einen oder aller ihrer Schneidflächen Chromoxyd enthält.According to the invention, a razor blade is created that at least in the surface of its one or all of their cutting surfaces contain chromium oxide.
Die Maßnahme, diese Flächen mit Chromoxyd zu versehen, wird vorgenommen, um der Rasierklinge durch eine Steigerung der Dauerhaftigkeit für die Schneidkante verbesserte Eigenschaften zu geben.The measure to provide these surfaces with chromium oxide, is made to the razor blade by increasing the durability for the cutting edge to give improved properties.
Ein Verfahren zur Herstellung der mit Chromoxyd versehenen Oberfläche besteht erstens darin, diese Oberfläche mit Chrom zu Überziegen, das anschliessend oxydiert wird. Eine weitere Möglichkeit besteht darin, die Oberfläche mit Chromoxyd zu überziehen,wobei der Oxydationsvorgang gespart wird. Bei noch einer weiteren Methode kann der Chromsehalt mindestens im Oberflächen-One method for producing the surface provided with chromium oxide consists firstly in this surface to be coated with chrome, which is then oxidized. Another option is to use the Surface to be coated with chromium oxide, the process of oxidation is saved. In yet another method, the chromium content can be at least in the surface
