MARKING COMPOSITION BASED ON INORGANIC LUMINOPHORES, METHOD FOR MARKING METAL ITEMS AND METAL ITEM |
摘要 |
The invention relates to compositions of inorganic phosphors suitable for protecting valuable material objects against counterfeit. A composition for marking metal products produced by powder metallurgy technique includes a phosphor and a binding/lubricating agent as which fatty acid derivatives or synthetic wax powders and/or paraffin powders are used. A method for marking metal products consists in mixing a metal alloy powder with a marking composition, followed by compacting the resultant mixture and sintering. The invention provides for the achievement of an even distribution of a marking component in the metal powder, and also effective marking of the products in the process of manufacture thereof by powder metallurgy technique, and a simplification and safety of the marking technique. |
