Definitions

  • the present invention relates to a metal fiber comprising several metals or metal alloys and to a method of manufacturing such a fiber.
  • Metal fibers are already well known in the art. The best known example is given by metal fibers obtained by bundle drawing methods.
  • Bundle drawn metal fibers may comprise different metal alloys, as explained in JP 5-177243.
  • Metal fibers obtained by coil shaving methods are known from US 4930199.
  • Such metal fibers may be used to provide a metal fiber media for several different applications, such as filtration of liquids or gasses, burner membranes or catalytic carriers.
  • the metal fiber media are to be combined with an other metal or metal alloy, in order to provide specific properties to the metal fiber medium, such as catalytic properties.
  • the metal fiber media itself is coated with another additional metal or metal alloy, which may result in an uneven distribution of the additional metal or metal alloy throughout the metal fiber medium.
  • each metal or metal alloy is present at the outer surface of the fibers.
  • a combination of metal can be done by blending metal fibers out of two or more types of metal fibers, each being provided out of a specific metal or metal alloy.
  • a noble metal is to be present in the blended metal fiber medium, one type of fiber may be provided out of a base metal, being coated with precious metal or metal alloy.
  • the use of two or more types of metal fibers, to provide combinations of metal alloys in a metal fiber media, has a disadvantage that at least two different metal fibers, out of two different metals or metal alloys are to be produced separately, after which a well mixed blend must be realized. Even in the case such well mixed blend may be obtained, there is a need for a better and more homogeneous distribution of metals in the metal fiber medium. This is especially the case if one of the metals or metal alloys comprises noble metals as a compound.
  • the present invention has an object to provide a metal fiber which facilitates and simplifies the process of manufacturing of metal fiber media comprising more than one metal alloy.
  • the present invention has further as an object to provide a metal fiber which is cheap in production and which reduces the cost of making metal fiber media comprising more than one metal alloy. This especially in case noble metals are to be used and combined.
  • the present invention has an object to provide a metal fiber which provide to the process of manufacturing of metal fiber media an increased flexibility in combination of different metal alloys and the ratio of such different alloys.
  • the present invention has an object to provide a metal fiber which improves the homogeneity of distribution of different metal alloys present in a metal fiber media comprising more than one metal alloy.
  • a metal fiber as subject of the invention has a cross section.
  • This cross section has a perimeter.
  • the metal fiber is characterized in that the cross section comprises at least a first and a second zone. Each of these zones provides a part of the perimeter.
  • the first zone is composed of a first metal or metal alloy M1
  • the second zone is composed of a second metal or metal alloy M2, whereby M1 is different from M2.
  • the cross section of the metal fiber is preferably substantially polygonal, most preferred substantially quadrangular such as substantially rectangular or substantially square.
  • cross section is meant a section of the metal fiber perpendicular to the main axis of the metal fiber.
  • substantially polygonal is meant that the profile of the cross section has the shape of a polygonal, such as a quadrangle, a rectangle or a square, but the sides of the polygon may not be absolute straight between two angles of the polygon. The sides may also include minor protuberances or indentations or may be corrugated.
  • Such metal fibers may be obtained by using following method of production of metal fibers. - Providing a foil or plate which is composed of metal or metal alloy M1 ; - Applying at a first side of said foil or plate a layer of a second metal or metal alloy M2; - Coiling up said foil or plate comprising M1 and M2 on a shaft; - Rotating said shaft with coiled foil or plate and cutting the end surface of said coiled foil or plate using a cutting tool.

  • the sides of the polygon may not be absolute straight between two angles of the polygon.
  • the sides may also include minor protuberances or indentations or may be corrugated. This is especially the case using common industrial cutting tools.
  • Providing metal fibers in this way has several advantages. Applying a layer of a second metal to the foil or plate can be done fairly easily using different processes.
  • the thickness of the layer can be varied to a large extent, which enables one to vary easily the content of M1 and M2 in the cross section of the fibers obtained.
  • An extra advantage is that, in case M2 is composed of a precious or semi-precious metal or metal alloy, the thickness of the layer M2 can be reduced to a minimum (as an example less than 5 ⁇ m or even less than 100 A). This enables to reduce the price of the metal fibers with such precious or semi-precious metal or metal alloy at the outer surface of the fiber.

  • the metal fibers as subject of the invention may comprise more than two, as an example three or even more metal or metal alloys.
  • Each of the metals provide a zone of the cross section. These zones provide each a part of the perimeter of the metal fibers cross section. This means that each metal or metal alloy is externally exposed.
  • the method may comprise one or more additional steps of applying additional layers of different metals or metal alloys to one or both sides of the metal foil prior to the coiling step.
