Boima ba tungsten carbide bo phahame haholo, ke e 'ngoe ea lisebelisoa tse nang le boima bo phahameng ka ho fetisisa har'a tšepe,' me boima ba eona ba Mohs bo ka fihla ho 9-9,5.Sena se etsa hore tungsten carbide e be thepa e loketseng bakeng sa ho etsa lisebelisoa le lithipa tse thata haholo.
Tungsten carbide hangata ke thepa e kopantsoeng le likarolo tsa tšepe tse kang tungsten carbon le li-binders tse kang cobalt le nickel, 'me boima ba eona hangata bo pota-potile 8-9.Har'a tsona, tungsten carbide ke e 'ngoe ea likarolo tse nang le boima bo phahameng ka ho fetisisa ka har'a carbide e entsoeng ka samente,' me boima ba eona ba Mohs bo ka fihla ho 9-9.5, kahoo e sebelisoa haholo ha ho etsoa lisebelisoa le lithipa tse thata haholo.Carbide e entsoeng ka samente e nang le cobalt e ngata ka har'a sebopeho e na le khanyetso e ntle ea kutu le ho hanyetsa ho roala.
Ho thatafala ha alloy e thata ke HRA89-92.5, e phahameng haholo, kahoo ho thata ho etsa lisebelisoa tse bōpehileng tse rarahaneng.Mofuta oa pele oa lefats'e oa motsoako o thata o tsoa ho 1923, ha rasaense oa Lejeremane Schloetter a nahana ka tšohanyetso, phofo ea tungsten carbide e kentse 10% ~ 20% cobalt, e entseng tungsten carbide le cobalt motsoako o mocha.
Carbide e na le boima ba 86 ho isa ho 93HRA
Hard alloy e entsoe ka mefuta e fapaneng ea carbide ea tšepe e le lisebelisoa tse tala, boima ba eona bo botle, ho hanyetsa ho roala le ho hanyetsa kutu, tse tsejoang e le meno a indasteri.Empa brittleness ea eona e kholo, e ke ke ea e-ba machining, e thata ho etsa sebōpeho sa lintho tse rarahaneng.
Alloy ea pele e thata ho tloha ka 1923, rasaense oa Jeremane Schloetter.Ho qaptjoa ha tungsten carbide le cobalt alloy e ncha, boima bo phahame haholo, ke mofuta oa pele oa lefats'e oa motsoako o thata, 1929, rasaense oa Amerika Schwarzkopf ho ntlafatsa, alloy e thata butle-butle e ile ea ntlafatsoa.
Hard alloy hardness e phahame haholo ho feta tšepe e tloaelehileng, kahoo tšebeliso ea eona e sebelisoa haholo-holo ho khaola tšepe e tloaelehileng.Ka keketseho e potlakileng ea indasteri ea likoloi tsa China, tlhoko ea lisebelisoa tsa ho seha e ntse e eketseha, 'me mmaraka oa carbide e samenteng le ona oa hola.
