Abstract: Nd-Fe-B magnets are a critical material for the green energy transition. However, price volatility makes the supply chain fragile, which makes the recycling process an alternative to reduce dependence on raw materials. Unfortunately, the recycling process introduces oxygen into the magnet, getting worse magnetic properties. Thus, this article studies Leia mais…

Abstract: Monitoring concrete structures is crucial for assessing the corrosion risk of steel reinforcement and optimizing maintenance strategies. This study evaluated the MnO₂/NaOH, Ag/AgCl, and Ti/MMO permanent, embeddable reference electrodes, which are rarely known or used in Brazil for corrosion monitoring. The electrodes underwent assessment tests, immersion tests in solutions Leia mais…
