Definitions

  • the present invention relates generally to metallurgy but more particularly to a method for making bi-metallic members.
  • Bi-metallic coins are used in many countries as their higher denomination coinage because it is difficult to replicate or counterfeit. Other objects such as medals and tokens also use bi-metals in a similar fashion. Bi-metallic members are usually composed of a core and a ring that are either electroplated steel or metallic alloy. Coins, because of their handling, tend to wear out fast and lose their shininess. Because of that, coins are regularly recuperated by banks who send them back to the mint where they are melted and recycled into new coins. The process of melting and stamping new coins is quite onerous. Depending on the amount of coins a particular country has in circulation, even if a small percentage is being recycled, that cost can be noticeable. If coins could last longer, millions could be saved in coin stamping.
  • the invention consists in the process of making bimetallic members with an inner core made of anodized aluminum.
  • the anodizing process can not only color aluminum in any one of a variety of colors, but the process also provide a very strong coating on the surface. In fact, only diamonds are known to be harder than an anodized aluminum coating.
  • the insertion and stamping can be done using the same process currently used in minting coins and as such, does not require any new equipment. Also, both parts of the piece can be made from aluminum and colored differently. This principle is to ensure that there will be no discoloration or tarnishing on the anodized parts.
  • the method further includes the steps of:
  • stamping said bi-metallic member to thereby hold said metallic inner core member and said metallic outer ring 15 member together.
  • the step of stamping the bi-metallic member further includes providing an engraved image upon the surfaces of the metallic inner core member and the metallic outer ring member, to thereby provide an identifying image upon the bi-metallic member which can then be used as a monetary coin, token or medal.
  • the metallic outer ring member is formed from a metallic material chosen from a list of metallic materials comprising aluminum, steel, iron, copper, nickel, zinc, niobium, gold, silver, and platinum.
  • the metallic inner core member is formed from a non-ferrous metal chosen from a list comprising aluminum, niobium, zinc, and platinum.
  • the shape of the inner hollow section of the metallic outer ring member is formed as a cylindrical volume.
  • the shape of the metallic inner core member is formed as a cylindrical volume.
  • Type III "hard coat” is preferably used as the anodizing method.
  • Figs. 1A-C Isometric views of a completed coin, an outer ring, and an inner core, respectively.
  • FIGs. 2A-B Side cutaway view of a coin, and close up of the interface between the outer ring and the inner core with its anodized section.
  • FIG. 3A Side elevation of a coin and a coin stamping press.
  • a method for making a colored anodized aluminum inner core (10) for making a bi-metallic member (12), such as a coin, token or a medal having a metallic outer ring member (14), consists in a first step of anodizing the inner core (10) with a coloring agent so as to create an anodized portion (15).
  • the inner core (10) is inserted into an inner hollow section (16) of the outer ring member (14) so as to make the bi-metallic member (12).
  • the bi-metallic member (12) is created, it is stamped with an engraving image into a coin or medal.

Abstract

L'invention concerne un procédé de fabrication d'un noyau interne en aluminium anodisé coloré pour la fabrication d'un élément bimétallique, comme une pièce ou une médaille comprenant un élément annulaire externe métallique, qui est constitué d'une première étape d'anodisation du noyau interne avec un agent colorant afin de créer une partie anodisée. Une fois anodisé, le noyau interne est inséré dans une section creuse interne de l'élément annulaire externe de manière à produire l'élément bimétallique. Une fois l'élément bimétallique créé, il est estampé avec une image gravée pour obtenir une pièce, un jeton ou une médaille.
