Ukuhlukaniswa Kwezakhiwo:
- I-Titanium Carbide (TiC): Ukuqina kwayo kuseduze nokwedayimane, okulenza libe yilungu lomndeni wezinto ezibonakalayo ezinzima kakhulu. Ukuminyana kwayo okuphezulu kuvumela ukuma okunembile kumathuluzi anembayo adinga "isisindo". Kodwa-ke, inokonakala okuphezulu futhi ijwayele ukucwiliswa ngaphansi komthelela, ngakho ifaneleka kakhulu kuzimo ezimile, eziphansi - zokusika/ukugqokwa - ukumelana nezimo. Isibonelo, isetshenziswa kaningi njengesimbozo kumathuluzi. I-TiC coating iqinile kakhulu - iqinile futhi ayigugi - imelana, njengokubeka "izikhali zokuzivikela" kunsimbi yesivinini esikhulu namathuluzi e-carbide enosimende. Uma usika insimbi engagqwali ne-alloy steel, ingamelana namazinga okushisa aphezulu futhi inciphise ukuguga, inwebe kakhulu impilo yamathuluzi. Isibonelo, ekuhlanganisweni kokuqedela abasiki bokugaya, kwenza ukusika okusheshayo nokuzinzile.
- I-Silicon Carbide (SiC): "Umdlali osezingeni eliphezulu emazingeni okushisa aphezulu"! Ingakwazi ukugcina ukusebenza okuzinzile ngaphezu kuka-1600 ℃. Esimeni se-ceramic, ukuzinza kwayo kwamakhemikhali kuyaphawuleka futhi ayihlangani neze nama-acids nama-alkali (ngaphandle kwabambalwa njenge-hydrofluoric acid). Kodwa-ke, i-brittleness iyindaba evamile yezinto ze-ceramic. Noma kunjalo, i-single - crystal silicon carbide (efana ne-4H - SiC) ithuthukise ukuqina futhi yenza ukubuya kwama-semiconductors kanye namadivayisi wefrikhwensi ephezulu. Isibonelo, amathuluzi e-ceramic asekelwe ku-SiC "abafundi abaphezulu" phakathi kwamathuluzi e-ceramic. Zinezinga eliphezulu - ukumelana nokushisa kanye nokuzinza kwamakhemikhali. Lapho usika ama-alloys okuqina aphezulu (njengama-alloys asekelwe ku-nickel) kanye nezinto eziphukayo (njengensimbi ewugqinsi), awajwayele ukunamathela amathuluzi futhi aguge kancane. Kodwa-ke, ngenxa ye-brittleness, zifaneleka kakhulu ukuqeda ngokusika okungaphazamiseki kancane kanye nokunemba okuphezulu.
- I-Cemented Carbide (WC - Co): Umdlali "ophezulu - wesigaba enkundleni yokusika"! Kusukela kumathuluzi e-lathe kuya kubasiki be-CNC bokugaya, kusukela ensimbi yokugaya kuya etsheni lokumba, ingatholakala yonke indawo. I-carbide enosimende enokuqukethwe kwe-Co ephansi (efana ne-YG3X) ifanele ukuqedwa, kuyilapho leyo enokuqukethwe kwe-Co ephezulu (njenge-YG8) inamandla okumelana nomthelela futhi ikwazi ukuphatha imishini enzima kalula. Izigaba eziqinile ze-WC zinesibopho sokugqoka "ukumelana", futhi i-Co binder isebenza "njengeglue" ukuze ibambe izinhlayiya ze-WC ndawonye, igcine kokubili ubulukhuni nokuqina. Nakuba izinga lokushisa eliphakeme - ukumelana nokushisa lingelihle njengalezi ezimbili zokuqala, ukusebenza kwayo okulinganiselwe jikelele kwenza ifaneleke uhla olukhulu lwezimo kusukela ekusikeni kuya ekugqokeni - izingxenye eziphikisanayo.
