Testing a nano-barcodes marking technology for identification and protection of the mechanical products

Abstract

The article presents a technology for application and identification of nano-barcodes on the surface of industrial products. The essence of this process is to modify the surface of metallic materials by exposure to pulsed laser radiation. As a result of such exposure, the modified surface contains small labels, allowing storing encoded information directly on the machine part, bypassing intermediate carriers. The laser-applied labels are formed using software and encode informative data. The encoding of the input information ensures the uniqueness of the applied nano-barcodes. The proposed technology allows us to apply such unique labels on the materials surface for accounting and identification of industrial products. The proposed marking technology allows us to place a significant amount of information in a small area. Special software has been developed for decoding the information from the applied nano-barcode developed. Studies have been performed that have been conducted to determine the thickness of the marked symbols formed on the materials surfaces and the reliability of the applied symbols. There are also recommendations on the usage of the technology given for direct labeling of materials with the application of information with high recording density for various industries.
