Formation of Hard Alloy VK8 Using Tungsten Carbide Powder Synthesized by Mechanochemical Technology

Spark Plasma Sintering of WC-Based 10wt%Co Hard Alloy: A Study of Sintering Kinetics and Solid-Phase Processes

“…However, despite the widely conducted research with alternative binders, the most popular alloy is still based on the WC-Co system. Around 90% of tungsten carbide hard metals are made using a cobalt binder [ 26 , 27 , 28 ]. The possibility of obtaining composite WC-Co system micro-powders with spherical particle shape having submicron and nanoscale (50 nm) structure [ 29 ] with uniform distribution of W, Co, and C among powder nanoparticles in the nanoscale range has been widely experimentally confirmed.…”

Physicochemical properties of lead brass charge obtained by electroerosion in isopropyl alcohol under optimal dispersion regimes

“…The addition of zinc increases corrosion resistance. However, due to the scarcity of lead and zinc, their content should be reduced and, if possible, they should be replaced by cheaper elements [5][6][7][8]. The solution to this problem may be the recycling of brass containing scarce components [14 -19].…”

Composition, structure and properties of hard alloy products from electroerosive powders obtained from T5K10 hard alloy waste in kerosene

“…Currently, one of the main problems in using hard alloys is the high cost of tungsten, titanium, and cobalt [5][6][7][8]. This problem can be solved by grinding their waste and reusing them.…”
