“…Due to its intrinsic resistance to oxidation and corrosion at elevated temperatures, WC is an excellent candidate for protective coatings for high-temperature electronics [ 47 , 48 ]. Unfortunately, nanocrystalline bulk WC materials are rarely used in industrial scale applications due to their limited sinterability even at elevated temperatures (1650–1900 °C) [ 49 , 50 , 51 , 52 ]. The possibility of improving mechanical properties including as hardness, elastic modulus, and fracture toughness has sparked interest in the manufacture of nanocrystalline WC ultrafine powders.…”

“…Numerous methods, including chemical synthesis [ 46 ], mechanically induced solid state reduction [ 53 ], plasma-chemical interaction [ 54 ], and chemical vapor deposition (CVD), can be employed to synthesize polycrystalline superfine WC powders with an average grain size of 300–40 nm. However, mechanical milling (MM) is believed to be the most potent approach for generating nanocrystalline WC ultrafine powders on an industrial scale at near room temperature [ 51 , 53 ]. It has been demonstrated that ultrafine WC nanopowders with a spherical-like shape may be successfully generated employing WC milling equipment with a ball-to-powder weight ratio of 50:1 [ 51 ].…”

“…Os pós ultrafinos contribuem positivamente no processo de sinterização, mas também podem gerar grandes dificuldades de processamento HU;RAHAMAN, 1994;STERNITZKE, 1997 tempo, o calor é gerado em toda a amostra e de dentro para fora, provocando a formação de gradientes de temperatura e fluxos de calor invertido (BORRELL et al, 2013;SUTTON,1996). Com isso, peças grandes são rápida e uniformemente aquecidas, evitando a geração de grandes tensões térmicas que, consequentemente, causariam trincas ou danos ao material (SCHIFFMAN, 1995).…”
