Amathuluzi e-carbide ahlanganisiwe anezinzuzo ezilandelayo:
(1) Impahla yokumboza yongqimba olungaphezulu inokuqina okuphezulu kakhulu nokumelana nokugqoka. Uma kuqhathaniswa ne-carbide ehlanganisiwe engahlanganisiwe, i-carbide enosimende eboshwe ivumela ukusetshenziswa kwesivinini sokusika esiphezulu, ngaleyo ndlela ithuthukise ukusebenza kahle kokucubungula, noma Ingakwazi ukwandisa kakhulu impilo yamathuluzi ngesivinini esifanayo sokusika.
(2) I-coefficient yokungqubuzana phakathi kwezinto ezimboziwe kanye nezinto ezicutshungulwayo zincane. Uma kuqhathaniswa ne-carbide engasindisiwe engahlanganisiwe, amandla okusika e-carbide ehlanganisiwe ancishiswa ngezinga elithile, futhi ikhwalithi yendawo ecutshungulwayo ingcono.
(3) Ngenxa yokusebenza kahle okuphelele, ummese oboshiwe we-carbide unokuguquguquka okungcono kanye nobubanzi bohlelo lokusebenza. Indlela evame ukusetshenziswa kakhulu yokuhlanganisa i-carbide enosimende ukushisa okuphezulu kwe-chemical vapor deposition (HTCVD). I-Plasma chemical vapor deposition (PCVD) isetshenziselwa ukumboza ingaphezulu le-carbide enosimende.
Izinhlobo zokumboza zabasiki begayidi be-carbide:
Izinto ezintathu ezivame kakhulu zokuhlanganisa i-titanium nitride (TiN), i-titanium carbonitride (TiCN) ne-titanium aluminide (TiAIN).
Ukufakwa kwe-Titanium nitride kungakhuphula ubulukhuni nokumelana nokugqoka kwendawo yamathuluzi, kunciphise i-coefficient yokungqubuzana, kunciphise ukukhiqizwa konqenqema olwakhelwe phezulu, futhi kunwebe ukuphila kwethuluzi. Amathuluzi enziwe nge-Titanium nitride afanele ukucubungula insimbi ene-alloy ephansi nensimbi engagqwali.
Ingaphezulu le-titanium carbonitride coating limpunga, ukuqina kuphakeme kunokwembozo ye-titanium nitride, futhi ukumelana nokugqokwa kungcono. Uma kuqhathaniswa ne-titanium nitride coating, ithuluzi lokumboza le-titanium carbonitride lingacutshungulwa ngesivinini esikhulu sokuphakelayo kanye nesivinini sokusika (ama-40% no-60% aphakeme kunalelo le-titanium nitride coating, ngokulandelana), futhi izinga lokususwa kwezinto zokusebenza liphezulu. Amathuluzi ahlanganiswe ne-Titanium carbonitride angakwazi ukucubungula izinto ezihlukahlukene zokusebenza.
I-titanium aluminide enamathelayo impunga noma imnyama. Imbozwe ngokuyinhloko phezu kwesisekelo samathuluzi e-carbide enosimende. Isengacutshungulwa lapho izinga lokushisa lokusika lifinyelela ku-800 ℃. Ifanele ukusika okomile ngesivinini esikhulu. Ngesikhathi sokusika okomile, ama-chips endaweni yokusika angasuswa ngomoya ocindezelwe. I-Titanium aluminide ilungele ukucubungula izinto eziphukayo njengensimbi eqinile, ingxubevange ye-titanium, ingxubevange esekwe nickel, insimbi yokusansimbi kanye ne-silicon aluminium alloy ephezulu.
Ukusetshenziswa kokufakwa kwe-cemented carbide milling cutter:
Inqubekelaphambili yobuchwepheshe bokuhlanganisa ithuluzi ibonakala ekusebenzeni kwe-nano-coating. Ukumboza amakhulu ezingqimba zezinto ezinogqinsi lwama-nanometer amaningana kusisekelo samathuluzi kubizwa ngokuthi i-nano-coating. Ubukhulu bezinhlayiya ngayinye ye-nano-coating material incane kakhulu, ngakho-ke umngcele wokusanhlamvu mude kakhulu, onobulukhuni obuphezulu bokushisa. Amandla nokuqina kokuphuka.
Ubulukhuni be-Vickers be-nano-coating bungafinyelela ku-HV2800～3000, futhi ukumelana nokugqokwa kuthuthukiswa ngo-5% ~50% kunaleyo yezinto ze-micron. Ngokwemibiko, okwamanje, izendlalelo ezingu-62 zamathuluzi okunamathela anezimbotshana ezishintshanayo ze-titanium carbide ne-titanium carbonitride nezingqimba ezingu-400 zamathuluzi e-TiAlN-TiAlN/Al2O3 ahlanganiswe nano-coated.
Uma kuqhathaniswa nalezi zingubo eziqinile ezingenhla, i-sulfide (i-MoS2, i-WS2) eboshwe ngensimbi enejubane elikhulu ibizwa ngokuthi i-soft coating, esetshenziselwa ikakhulukazi ukusika ama-alloys e-aluminium anamandla amakhulu, ama-titanium alloys nezinye izinsimbi ezingavamile.
Uma unesidingo, sicela uxhumane ne-XINFA, sizimisele ukunikeza amathuluzi osayizi ojwayelekile ngesikhathi esifushane kanye nohlelo lwamathuluzi enziwe ngokwezifiso kumakhasimende.
