Ka ho fetola boholo ba lijo-thollo tsa tungsten carbide le cobalt content ka har'a matrix, le ho eketsa lisebelisoa tse ling, baenjiniere ba na le monyetla oa ho fumana sehlopha sa lisebelisoa tseo thepa ea tsona e ka etsoang ho latela mefuta e fapaneng ea likopo tsa boenjiniere.Sena se kenyelletsa lisebelisoa tsa theknoloji e phahameng, likarolo tse roaloang le lisebelisoa bakeng sa lekala la merafo ea kaho le oli le khase.
Lihlahisoa tsa Tungsten Carbide ke litholoana tsa ts'ebetso ea phofo ea metallurgy eo haholo-holo e sebelisang tungsten carbide le phofo ea tšepe ea cobalt.Ka tloaelo, metsoako ea metsoako e tla tloha ho 4% ea cobalt ho ea ho 30% ea cobalt.
Lebaka le ka sehloohong la ho khetha ho sebelisa tungsten carbide ke ho nka monyetla ka boima bo phahameng boo lisebelisoa tsena li bo bonts'ang, ka hona, ho fokotsa sekhahla sa ho roala ha likarolo tsa motho ka mong.Ka bomalimabe, kotlo e amanang le boima bo phahameng ke ho hloka boima kapa matla.Ka lehlohonolo, ka ho khetha lipina tse nang le litaba tse phahameng tsa cobalt, matla a ka fihlelleha hammoho le boima.
Khetha litaba tse tlase tsa cobalt bakeng sa lits'ebetso moo karolo e ke keng ea lebelloa ho ba le tšusumetso, ho fihlela boima bo phahameng, khanyetso e phahameng ea ho apara.
Khetha litaba tse phahameng tsa cobalt haeba ts'ebeliso e kenyelletsa ho ts'oha kapa ts'usumetso le ho fihlela khanyetso e kholo ea ho roala ho feta lisebelisoa tse ling tse ngata, ho kopantsoe le bokhoni ba ho hanela tšenyo.
