Iyini i-tungsten carbide?

I-tungsten carbideis eyaziwa nangokuthi i-cemented carbide. I-Tungsten carbide iwuhlobo lwe-alloy material ene-refractory tungsten (W) material micron powder njengesithako esiyinhloko, ngokuvamile esukela ngesilinganiso phakathi kuka-70% -97% wesisindo esiphelele, kanye ne-Cobalt (Co), i-Nickel (Ni), noma i-Molybdenum. (Mo) njengomxhumanisi.

Njengamanje, i-W isesimweni seWCisetshenziswa kakhulu ekukhiqizeni i-carbide enosimende.i-tungstenI-carbide iyinto eyakhiwe ngokuhlanganisa izinhlayiya eziqinile ze-WC eyodwa ku-matrix ye-cobalt (Co) eqinile ye-binder nge-liquid-phase sintering. Ezingeni lokushisa eliphezulus, i-WC incibilike kakhulu ku-cobalt, futhi i-liquid cobalt binder nayo ingenza i-WC ibe nokumanzisa okuhle, okuholela ekuhlanganeni okuhle kanye nesakhiwo esingeyona i-pore kunqubo ye-liquid-phase sintering. Ngakho-ke, i-tungsten carbide inochungechunge lwezakhiwo ezinhle kakhulu, njenge:

*ukuqina okuphezulu:Mohs’ubulukhuni busetshenziswa kakhulu ekuhlukaniseni amaminerali. Isikali seMorse sisuka ku1kuye 10(Inombolo enkulu, ubulukhuni buyanda).Ubulukhuni be-Mohs be-tungsten carbide buyi9 kuya ku-9.5,Inezinga lokuqina okwesibili kunedayimaneubulukhuni obungu-10.

*ukumelana nokugqoka: Ukuphakama kokuqina, kungcono ukumelana nokugqokwa kwe-tungsten carbide

*ukumelana nokushisa: Njengoba inamandla aphezulu ekushiseni okuphezulu kanye ne-coefficient ephansi yokwandisa okushisayo, iyimpahla yokusetshenziswa efanele yamathuluzi okusika okufanele asetshenziswe endaweni yokushisa ephezulu kanye nesivinini esikhulu.

*Cukumelana ne-orrosion: I-Tungsten carbide iyinto ezinzile kakhulu, engakwazi ukuncibilika emanzini, i-hydrochloric acid noma i-sulfuric acid. Ngaphezu kwalokho, akunakwenzeka ukwakha isisombululo esiqinile esinezici ezihlukahlukene, futhi singagcina izici ezinzile ngisho nasezindaweni ezinzima.

Ikakhulukazi ubulukhuni bayo obuphezulu nokumelana nokushisa, okuhlala kungashintshile ngisho naku-1000 ℃. Ngezinzuzo eziningi kangaka, i-tungsten carbide ingasetshenziswa ukwenza amathuluzi okusika, imimese, amathuluzi okubhola, nezingxenye ezingagugi, futhi isetshenziswa kabanzi embonini yezempi, i-aerospace, ukucutshungulwa kwemishini, i-metallurgy, ukumba i-petroleum, amathuluzi ezimayini, i-electronic. ezokuxhumana, ezokwakha, neminye imikhakha. Yingakho eyaziwa ngokuthi "amazinyo ezimboni".

I-Tungsten carbide iqinile izikhathi ezi-2-3 njengensimbi futhi inamandla acindezelayo adlula zonke izinsimbi ezaziwayo ezincibilikisiwe, ezisansimbi, nezimboziwe. Imelana kakhulu nokuguqulwa futhi igcina ukuqina kwayo kokubili kubanda kakhulu kanye namazinga okushisa ashisayo. Ukumelana nomthelela wayo, ukuqina, kanye nokumelana nokugalela/ukuhuzuka/ukuguguleka kukhethekile, kuhlala isikhathi esiphindwe kayi-100 kunensimbi ezimeni ezimbi kakhulu. yenza ukushisa ngokushesha kakhulu kunensimbi yamathuluzi. I-tungsten carbideingaphinda iphonswe futhi icinywe ngokushesha ukuze yakhe isakhiwo sekristalu esiqinile kakhulu.

Ngokuthuthukiswa kweiembonini engaphansi komfula, isidingo semakethe se-tungsten carbide siyakhula. Futhi esikhathini esizayo, ukwakhiwa kwemishini yezikhali zobuchwepheshe obuphezulu, inqubekelaphambili yesayensi nobuchwepheshe obusezingeni eliphezulu, kanye nokuthuthukiswa okusheshayo kwamandla enuzi kuzokwandisa kakhulu isidingo semikhiqizo ye-carbide enosimende enokuqukethwe kobuchwepheshe obuphezulu nokuphezulu.-ukuzinza kwekhwalithi.
