Document Type and Number:
Japanese Patent JP2003517152
Kind Code:
A
Abstract:
In the method of protecting and identifying a three-dimensional article such as a work of art, a precious article, or an industrial component that is made by a foundry, casting, or like technique, marker elements (50) are included in the main material (30) of the article during manufacture thereof, the nature of the marker elements being different from that of the main material (30) of the article so as to react to means for non-destructive investigation of the internal structure of the article in a manner that is different from said main material (30) of the article, metal marker elements (50) constituted by balls are selected that present a melting point higher than that of the main metal material (30) of the article, the marker elements (50) in the solid state are introduced in random manner and without premixing into the main material (30) of the article while it is in the liquid state and the article is being cast, and after the article has been made, it is identified by identifying marker elements in the internal structure of the article using an X-ray tomographic analysis technique. The method makes it possible to authenticate an article which is characterized by a reference plane and at least one section plane parallel to the reference plane and including the image of at least one marker element (50).
