Tungsten carbide hard alloy e etselitsoe ka ho khetheha hore e hane ho bola, ho khojoa, ho roala, ho ferekana, ho thella le ho ama ts'ebeliso ea lisebelisoa tsa lebopong le lebopong le kaholimo le ka tlase ho leoatle.

Tungsten carbide ke motsoako oa lik'hemik'hale oa inorganic o nang le lipalo tsa tungsten le liathomo tsa carbon. Tungsten carbide, eo hape e tsejoang e le "samente carbide", "hard alloy" kapa "hardmetal", ke mofuta oa lintho tse entsoeng ka metallurgic tse nang le tungsten carbide powder (chemical formula: WC) le binder tse ling (cobalt, nickel. joalo-joalo).

E ka hatelloa le ho etsoa ka libopeho tse ikhethileng, e ka siloa ka nepo, 'me e ka tšeloa kapa ea lokisetsoa litšepe tse ling. Mefuta e fapaneng le limaraka tsa carbide li ka etsoa joalo ka ha ho hlokahala hore li sebelisoe ts'ebelisong e reriloeng, ho kenyelletsa indasteri ea lik'hemik'hale, oli le khase le marine joalo ka lisebelisoa tsa merafo le ho seha, hlobo le ho shoa, likarolo tsa ho roala, jj.

Tungsten carbide e sebelisoa haholo mecheng ea indasteri, ho roala lisebelisoa tse hanyetsanang le ho bola. Tungsten carbide ke thepa e ntle ka ho fetisisa ea ho hanela mocheso le ho robeha ha thepa eohle e thata ea sefahleho.

Tungsten Carbide plate valve disc e sebelisoa haholo oli le khase ka lebaka la ho hanyetsa ho hoholo, khanyetso e phahameng ea kutu.

Tungsten carbide disc e sebelisoa haholo bakeng sa li-valve. Li-disc tse peli tse haufi e 'ngoe le e 'ngoe e na le likoti tse nepahetseng tsa twp (orifice). Diski e ka pele e phaphamala khahlano le disc e ka morao e theha sebopeho sa mated le ho netefatsa tiiso e ntle. Valve ea mofuta oa disc e sebelisa li-discs tse peli tsa Tungsten Carbide tse nang le masoba a geometry e ikhethang. The disc e ka holimo e potoloha ho ea ka disk e tlase (ka letsoho kapa ka actuator) e fapaneng le boholo ba orifice. Li-discs li pota-potiloe ka likhato tse 180 pakeng tsa boemo bo bulehileng le bo koetsoeng. Ntle le moo, li-disks tse lapped mattings tse etselitsoeng ho fana ka tiiso e ntle.
