Ingxenye yokuqala: Iyini i-carbide materials?
Ingxenye Yesibili: Kuyini ukusetshenziswa kwezinto ze-carbide?
Ingxenye Yesithathu: Yibuphi ubunzima ekusetshenzisweni kwengxenye ye-carbide?
Ingxenye yokuqala: Iyini i-carbide materials?
I-carbide enosimende yenziwe nge-tungsten carbide ne-cobalt.I-Tungsten carbide iyinto enephuzu eliphezulu lokuncibilika.Kudingeka ukuthi igaywe ibe yimpushana bese ikhiqizwa ngokushisa okuphezulu nokuqina, futhi i-cobalt yengezwa njengento ebophayo.I-Tungsten ivela ikakhulukazi eChina, eRussia naseNingizimu Korea, kanti i-cobalt ivela eFinland, eCanada, e-Australia naseCongo.Ngakho-ke, ukwenza ama-alloys ama-superhard kudinga ukubambisana komhlaba wonke ukuze kusetshenziswe le nto emangalisayo emikhakheni ehlukahlukene. titanium-cobalt (niobium).Okusetshenziswa kakhulu ekukhiqizeni i-tungsten-cobalt ne-tungsten-titanium-cobalt cemented carbide.
Ukuze wenze i-super hard alloy, kuyadingeka ukugaya i-tungsten carbide ne-cobalt ibe yimpuphu ecolekile, bese kushisa futhi kuqiniswe ekushiseni okuphezulu (1300 ° C kuya ku-1500 ° C) ukuze kuqiniswe impahla.I-Cobalt yengezwa njengento yokubopha ukusiza izinhlayiya ze-tungsten carbide zinamathelane.Umphumela uyinsimbi ehlala isikhathi eside enendawo yokuncibilika engu-2900 ° C, okwenza imelane namazinga okushisa aphezulu futhi ifaneleke kahle ekufakweni kwezinga lokushisa eliphezulu.
Ingxenye Yesibili: Kuyini ukusetshenziswa kwezinto ze-carbide?
I-carbide enosimende inezinhlobonhlobo zezinhlelo zokusebenza.Emkhakheni wokukhiqiza izimboni, isetshenziswa kakhulu ekwenzeni amathuluzi okusika okucubungula insimbi njengamathuluzi okugaya i-CNC, imishini yokugaya i-CNC, kanye ne-CNC lathes.Ngaphezu kwalokho, ingasetshenziswa ukwenza isikhunta samathini e-aluminium njengekhofi ekheniwe neziphuzo, isikhunta se-powder sezingxenye zenjini yezimoto (izingxenye ze-sintered), kanye nokubunjwa kwezingxenye ze-electronic ezifana nomakhalekhukhwini.
Mayelana nokukhiqiza nokucubungula, ukubaluleka kwe-super hard alloy kuyabonakala.Ngenxa yokuqina kwayo okuhle kakhulu namandla, ama-alloys ama-superhard asetshenziswa kakhulu emishinini yokwenza izinto njengamathuluzi okusika insimbi, amathuluzi okubhoboza, imishini yokugaya kanye nezinsimbi.Ngaphezu kwalokho, ingasetshenziswa ukwenza i-aluminium can isikhunta ikhofi ekheniwe kanye neziphuzo, isikhunta se-powder sokubumba izingxenye zenjini yezimoto (izingxenye ze-sintered), kanye nokubunjwa kwezingxenye ze-electronic ezifana nomakhalekhukhwini, njll.
Kodwa-ke, ama-alloys ama-superhard awagcini nje emkhakheni wokucubungula insimbi nokukhiqiza.Ingase futhi isetshenziselwe ukuchotshozwa kwamatshe aqinile, njengokwakhiwa kwemihubhe yesihlangu, nokusika imigwaqo yetiyela nezinye izinkambu.Ngaphezu kwalokho, ngenxa yezici zayo ezinhle kakhulu, ama-alloys aqinile angasetshenziswa kabanzi kweminye imikhakha ye-CNC machining.Isibonelo, amathuluzi okuhlinza asetshenziswa emkhakheni wezokwelapha, izinhlamvu nama-warhead emkhakheni wezempi, izingxenye zenjini nama-blade ophephela wendiza endaweni ye-aerospace, njll.
Ngaphezu kwesicelo embonini, ama-alloys ama-super hard nawo adlala indima emkhakheni wocwaningo lwesayensi.Isibonelo, ingasetshenziswa ukwenza izinti ze-diffraction ku-X-ray kanye nocwaningo lwe-optical, futhi njenge-catalyst ocwaningweni lokusabela kwamakhemikhali.
Ingxenye Yesithathu: Yibuphi ubunzima ekusetshenzisweni kwengxenye ye-carbide?
Ukucutshungulwa kwe-carbide enosimende akulula futhi kunezinkinga eziningi.Okokuqala, ngenxa yokuqina kwayo okuphezulu kanye nokuqina, izindlela zokucubungula zendabuko zivame ukuba nzima ukuhlangabezana nezidingo futhi zingaholela kalula emaphutheni afana nokuqhekeka nokuguqulwa komkhiqizo.Okwesibili, i-carbide enosimende isetshenziswa emasimini aphezulu, ngakho-ke izidingo zokunemba kwemishini ziphezulu kakhulu.Phakathi nenqubo yokucubungula, izici eziningi kufanele zicatshangelwe, njengamathuluzi okusika, ukulungiswa, imingcele yenqubo, njll, ukuze kuqinisekiswe ukunemba komkhiqizo.Okokugcina, izidingo zekhwalithi ephezulu ye-carbide enosimende nazo ziphakeme kakhulu.Ngenxa yokuqina kwayo okukhulu, indawo engaphezulu ilimala kalula, ngakho-ke izindlela ezikhethekile zokucubungula kanye nemishini (njengezigayi ezinembile kakhulu, amapholisha e-electrolytic, njll.) zidinga ukusetshenziswa ukuze kuqinisekiswe ikhwalithi ephezulu.
Ngamafuphi, i-carbide enosimende isetshenziswa ngokuqhubekayo ekusetshenzisweni kwemishini ye-CNC, idlala indima ebalulekile ekuthuthukiseni ukusebenza kahle kokukhiqiza kanye nekhwalithi yomkhiqizo emishinini, i-electronics, amakhemikhali, i-aerospace nezinye izimboni.I-GPM inemishini yokucubungula ethuthukisiwe kanye nobuchwepheshe obungakwazi ukucubungula izingxenye ze-supercarbide ngokuphumelelayo nangokunembile. .Isistimu yokulawula ikhwalithi eqinile phakathi nenqubo yokucubungula iqinisekisa ukuthi ingxenye ngayinye ihlangabezana nezidingo nezindinganiso zamakhasimende.
