Izinqubo Zokukhiqiza Izinkinobho Ze-Carbide

I-Tungsten carbide ingenye yezinto emhlabeni wonke ezisetshenziswa embonini. Inkinobho ye-carbide yenziwe nge-tungsten carbide, ngakho-ke inezindawo ze-carbide enosimende. Umumo wesilinda wezinkinobho ze-tungsten carbide wenza kube lula ukuwufaka kwamanye amathuluzi ngokufaka ukushisa nokucindezela okubandayo. Ngenxa yokuthi izinkinobho ze-carbide zibamba izici zokuqina, ukuqina, nokuqina, kuvamile ukuzibona ezimeni ezihlukahlukene ezifana nokubhoboza imithombo, ukugaya amatshe, ukusebenza komgwaqo, nomcimbi wezimayini. Kodwa inkinobho ye-carbide yenziwa kanjani? Kulesi sihloko, sizowuphendula lo mbuzo.

1. Ukulungiselela Impahla Engavuthiwe

Izinqubo ezilandelayo zidinga i-WC powder kanye ne-Cobalt powder. I-WC powder yenziwe ngama-tungsten ores, ambiwa futhi ahlawuliswe ngemvelo. I-Tungsten ores izobhekana nokuguquguquka kwamakhemikhali okuhlukahlukene, kuqala ngomoya-mpilo ukuze ibe i-tungsten oxide bese kuba nekhabhoni ibe yimpuphu ye-WC.

2. Ukuxuba Impushana

Manje nasi isinyathelo sokuqala sokuthi izimboni zenza kanjani amazinyo e-carbide. Izimboni zizokwengeza ezinye izibophezelo (i-Cobalt powder noma i-Nickel powder) ku-WC powder. Izibophezelo zifana "neglue" empilweni yethu yansuku zonke ukusiza ukuhlanganisa i-tungsten carbide iqine kakhulu. Abasebenzi kumele bahlole impushana exutshiwe ukuqinisekisa ukuthi ingasebenzisa lezi zinyathelo ezilandelayo.

3. Ukugayiwa Okumanzi

Ngalesi nqubo, impushana yokuxuba izofakwa emshinini Wokugaya Ibhola bese igaywa ngoketshezi olunjengamanzi ne-ethanol. Lolu ketshezi ngeke lusabele ngamakhemikhali kodwa lusiza ukugaya.

4. Futha Ukomisa

Le nqubo yenzeka njalo endaweni yokomisa. Kodwa izimboni ezahlukene zingakhetha izinhlobo ezahlukene zemishini. Izinhlobo ezimbili ezilandelayo zemishini zivamile. Enye iVacuum Dryer; enye iSpray Drying Tower. Banezinzuzo zabo. Fafaza umsebenzi wokomisa ngokushisa okuphezulu namagesi angenayo ukuze uhwamulise amanzi. Ingahwamulisa amanzi amaningi, okwenza kangcono kulezi zinqubo ezimbili ezilandelayo Ukucindezela kanye nokuSintering. I-Vacuum Drying ayidingi izinga lokushisa eliphezulu kodwa kuyabiza futhi kubiza kakhulu ukuyinakekela.

5. Ukucindezela

Ukucindezela impushana ibe yizimo ezihlukene ezidingwa amakhasimende, abasebenzi bazokwenza isikhunta kuqala. Izinkinobho ze-Carbide ziza ngezindlela ezihlukene ukuze ukwazi ukubona izinhlobo ezahlukene zokufa, ezinekhanda eliyindilinga, ikhanda lebhola, ikhanda le-parabolic, noma ikhanda lesipuni, eline-chamfer eyodwa noma amabili, kanye noma ngaphandle kwamaphinikhodi. Kunezindlela ezimbili zokubumba. Ngosayizi omncane wezinkinobho, abasebenzi bazocindezela ngomshini ozenzakalelayo; kwelikhudlwana, abasebenzi bazocindezela ngomshini wokucindezela osebenzisa amanzi amaningi.

6. Sintering

Abasebenzi bazofaka amathiphu e-carbide bit ecindezelwe epuletini le-graphite naku-Hot Isostatic Pressing (HIP) Sintered Furnace ngaphansi kwezinga lokushisa elingu-1400˚ C. Izinga lokushisa kufanele liphakanyiswe ngesivinini esiphansi ukuze inkinobho ye-carbide inciphe kancane futhi isiqediwe. inkinobho inokusebenza okungcono. Ngemuva kokucwiliswa, izoncipha futhi ibe nevolumu ecishe ibe uhhafu kunakuqala.

7. Ukuhlolwa kwekhwalithi

Ukuhlolwa kwekhwalithi kubaluleke kakhulu. Ukufakwa kwe-carbide kuqala kuhlolisiswa izakhiwo ezinjengokuqina, i-cobalt magnetic, ne-microstructure ukuhlola izimbobo noma imifantu emincane. I-micrometer kufanele isetshenziselwe ukuhlola ubukhulu bayo, ubude, nobubanzi bayo ngaphambi kokupakisha.
