I-Tungsten Carbide Engazweli Kakhulu

Njengoba sonke sazi, usayizi wokusanhlamvu we-tungsten carbide uba mncane, bukhuphula ubulukhuni bayo nokumelana nokugqoka. Kodwa-ke, uyazi ukuthi iyini i-tungsten carbide engagqoki kakhulu? Kulesi sihloko, sizokhuluma nge-tungsten carbide engagqoki kakhulu.

Ngokusho kobunzima obuhlukahlukene, i-tungsten carbide ingahlukaniswa ngezinhlobo eziningi zamamaki, njenge-YG8, YG15, njalonjalo. Imikhiqizo ye-tungsten carbide yenziwa nge-powder metallurgy, esebenzisa i-tungsten carbide njengeyona nto eyinhloko eluhlaza, futhi iyixube nempushana ehlanganisayo. Ngemuva kokuxuba, i-tungsten carbide powder kanye ne-binder powder izogaywa, yomiswe, icindezelwe, futhi ifakwe. Ngokuvamile, inani le-tungsten lingaphezu kwama-80%.

Ukumelana nokugqokwa kwe-tungsten carbide kunqunywa usayizi wayo wokusanhlamvu kanye nenani le-cobalt. Uma buncane usayizi wokusanhlamvu kanye nenani eliphansi le-cobalt, bukhuphula ubulukhuni be-tungsten carbide. Ngakho-ke lapho sikhetha umkhiqizo we-tungsten carbide, singanaka ubulukhuni bayo, imfuneko kanye nokusetshenziswa kwayo. Nakuba ukusebenza komthelela kuvame ngesikhathi somsebenzi, kufanele sicabangele ukumelana.

Uma sikhuluma ngokuthi yimiphi imikhiqizo ye-tungsten carbide evikela kakhulu ukugqokwa, okokuqala, kufanele sicabange ngalesi simo. Ngokuvamile, i-tungsten carbide ingahlukaniswa izigaba ezintathu.

1. I-YG: Uchungechunge lwe-YG lwenziwe nge-tungsten carbide powder njengempahla yalo eluhlaza kanye ne-cobalt powder njengesibophezelo salo. Imikhiqizo ye-Tungsten carbide eyenziwe ochungechungeni lwe-YG inokumelana okuhle, ukumelana nokugqokwa, kanye ne-thermal conductivity futhi isetshenziswa kabanzi ukwenza insimbi ekhonjiwe kanye nensimbi engeyona insimbi.

2. I-YT: Uchungechunge lwe-YT lwenziwe nge-tungsten carbide powder ne-cobalt powder, kanye nenye i-TiC powder. I-TiC ingangezwa ukuthuthukisa ukumelana nokugqokwa kwemikhiqizo ye-tungsten carbide futhi yehlise ukuqina kokugoba. Lolu hlobo lomkhiqizo we-tungsten carbide lunokuqina okuphezulu, ukumelana nokushisa okuphezulu, nokumelana ne-oxidation futhi kufanelekile ukukhiqiza insimbi.

3. I-YW: Uchungechunge lwe-YW lwenziwe nge-tungsten carbide powder, i-cobalt powder, i-TiC, ne-TaC. I-TaC yengezwa ukuthuthukisa amandla nokumelana nemikhiqizo ye-tungsten carbide. Lezi zinhlobo zemikhiqizo ye-tungsten carbide zilungele ukukhiqiza izinsimbi eziphezulu ze-alloy, ama-alloys angashisi ukushisa, ne-cast iron.

Uma unentshisekelo emikhiqizweni ye-tungsten carbide futhi ufuna ulwazi olwengeziwe nemininingwane, UNGATHI XHUMANA NATHI ngocingo noma ngemeyili kwesokunxele, noma SITHUMELE IMEYILI ezansi nekhasi.
