This article presents the results of studies to determine the influence of the amount of modifiers on the physical and mechanical properties of hard alloy samples based on tungstencobalt carbide. Ultrafine nanopowders of titanium carbide and tungsten carbide were chosen as modifiers. The influence...

The article presents the results of studies on the purification of sludge obtained by converting waste tungsten carbide and cobalt hard alloys into a cobalt solution with electrolysis to the state of pure tungsten carbide powders. Conducted scientific and practical studies show that the original...
