However, these conventional methods have many problems to be solved and they are not always established technologies. Therefore, a more economical and high-efficiency recycling procedure needs to be developed. In this study we investigated the applicability of the zinc-melt method (ZMM) for recycling WC-Co as a powder from cutting-tool scraps. It was proven that ZMM is an available technique for recovering the WC powder from the cutting tools. WC-Co powders are recovered and then spray dried, sintered and obtained as a feedstock material for thermal-spray coating processesPreiskovane so bile različne metode za recikliranje cermetov WC-Co iz orodij za rezanje, kot so kemijska modifikacija, termična modifikacija, metoda s hladnim tokom in elektrokemijska metoda, nekatere od njih pa se že uporabljajo v industriji. Vendar pa imajo te konvencionalne metode veliko problemov, ki jih je treba rešiti in nimajo vedno ustaljene tehnologije. Zato je treba razviti bolj ekonomične in visoko zmogljive postopke recikliranja. V tej študiji je bila preučevana uporabnost metode s taljenjem odpadkov rezilnih orodij v cinku (ZMM) za recikliranje WC-Co v obliki prahu. Dokazano je bilo, da je ZMM uporabna tehnika za pridobivanje WC-prahu iz orodij za odrezavanje. WC-Co-prahovi so bili najprej pridobljeni, nato posušeni z razprševanjem ter sintrani v obliko, primerno za termično nabrizgavanje prevlekTEXTznanstveno časopisjejournalsSlovenian National E-content AggregatorNational and University Library of SloveniaInštitut za kovinske materiale in tehnologije
