Izigaba Ezine Eziyinhloko Zokwelashwa Kokushisa Kwe-Tungsten Carbide
Izigaba Ezine Eziyinhloko Zokwelashwa Kokushisa Kwe-Tungsten Carbide
I-Tungsten carbide inokusebenza okuphezulu okunezinto ezinhle kakhulu zomshini nezomzimba, okuhlanganisa ukumelana nokugqokwa okuphezulu, ukumelana nokugqwala, amandla okugoba, amandla okugoqa, njll., esetshenziselwa kabanzi amathuluzi okusika, isikhunta esibandayo, izingxenye zokugqoka, njll. Lesi sihloko futhi sethula kafushane lezi ezine. izigaba eziyinhloko zokwelashwa kokushisa kwe-tungsten carbide, okungathuthukisa izakhiwo zomzimba nezomshini we-alloy eqinile.
Inqubo yokwelapha ukushisa kwe-tungsten carbide ingahlukaniswa ngezinyathelo ezine eziyinhloko.
1. Ukususwa kwezinto zokubumba kanye ne-pre-sintering
Esigabeni sokuqala se-sintering, i-ejenti eyakhayo iyabola kancane kancane noma ihwamuke, ngaphandle kwe-sintered body, ngasikhathi sinye, ama-ejenti akhayo afaka i-sintering, futhi inani lekhabhoni lizohluka ngokuya ngohlobo, inani, kanye nenqubo yokucwilisa. . I-powder surface oxide incishisiwe, futhi i-hydrogen inganciphisa i-cobalt nama-tungsten oxide ekushiseni kwe-sintering. Ngokusabela okubuthakathaka phakathi kwekhabhoni nomoya-mpilo, ukucindezeleka kokuxhumana phakathi kwezinhlayiya zempushana kususwa kancane kancane. I-powder yensimbi ebophayo iqala ukuphendula futhi i-recrystallization kanye nokusabalalisa kwendawo kuqala ukwenzeka. Amandla okuvimba anyukile.
2. Isiteji se-solid-phase sintering (800°C - izinga lokushisa le-eutectic)
Ebukhoneni besigaba se-liquid, ngaphezu kwenqubo yokuqhubeka nesigaba sangaphambilini, ukusabela kwesigaba esiqinile kanye nokusabalalisa kubhebhetheka ngokunyuka kokugeleza kwepulasitiki, futhi ukuncipha okucacile kubonakala emzimbeni we-sintered.
3. Isiteji se-liquid-phase sintering (izinga lokushisa le-eutectic - izinga lokushisa le-sintering)
Lapho isigaba samanzi somzimba we-sintered senzeka, ukucindezelwa kuqedwa ngokushesha, bese kuba noshintsho lwe-crystallization. Inhlangano eyisisekelo kanye nesakhiwo se-carbide kwakhiwa.
4. Isiteji sokupholisa (izinga lokushisa le-sintering - izinga lokushisa legumbi)
Kulesi sigaba, izingxenye zenhlangano nesigaba se-tungsten carbide zenza izinguquko ezithile ngaphansi kwezimo ezihlukahlukene zokupholisa, okwenza kube nokwenzeka ukusebenzisa lesi sici; ukwelashwa kokushisa kwe-alloy eqinile kuzothuthukisa izici zayo ezingokomzimba nezomshini.
I-ZZBETTER izinikele ekukhiqizeni imikhiqizo ye-tungsten carbide esezingeni lomhlaba nesezingeni eliphezulu. Imikhiqizo yethu idayiselwe amazwe amaningi nezindawo futhi yenza impumelelo enkulu emakethe yasekhaya.
Uma unentshisekelo emikhiqizweni ye-tungsten carbide futhi ufuna ulwazi olwengeziwe nemininingwane, UNGATHI XHUMANA NATHI ngocingo noma ngemeyili kwesokunxele, noma SITHUMELE IMEYILI ezansi nekhasi.
