Abstract :
[en] This paper explores the synergy of performance and sustainability in cemented carbides (Hartmetalle), based on tungsten carbide and cobalt, essential for high-wear applications like metal cutting, mining, and construction. It details recycling strategies—chemical, semi-direct, and direct (e.g., zinc process) —while maintaining properties like abrasion resistance and transverse rupture strength iincluding recycled materials; innovations in high-performance cutting (e.g., CERATIZIT CTC5240 for titanium), additive manufacturing (binder jetting, filament printing), microstructure simulations for crack propagation, and AI/ML optimization (e.g., XGBoost) of powder compositions to integrate recyclates efficiently. The outlook emphasizes closed-loop material cycles via digital tools for reduced ecological impact and enhanced economics.
