Abstract Scope |
Counterfeiting is a significant problem in global product market which has social and economic consequences, such as fiscal losses, failure of investments and unemployment. According to International Commission of Commerce in 2022, the total value of counterfeit products will reach $2.3 trillion, and their negative impact on global economy will be $4.2 trillion while putting 5.4 million employments at stake. We have recently developed a cost-effective countermeasure for counterfeiting, by embedding information as hidden magnetic barcodes via direct energy deposition of stainless steels with different magnetic properties. The local magnetic flux was measured in fabricated parts to obtain a magnetic flux intensity map, clearly revealing the embedded magnetic barcode. A comparison between microstructure of different stainless steels and magnetic flux intensities revealed the effects of process parameters on magnetic response. Optimization of processing parameters were discussed in the light of the challenges associated with incorporating this technique in practice. |
