Imibuzo mayelana no-COmposite Materialskanye ne-Tungsten Carbide

Izinto ezihlanganisiwe ziyizinto ezibalulekile zobunjiniyela ngenxa yezakhiwo zazo ezivelele zemishini. Izinhlanganisela ziyizinto lapho izakhiwo ezifiselekayo zezinto ezihlukene zihlanganiswa ngokuzibophezela ndawonye. Ingxenye ngayinye igcina ukwakheka kwayo kanye nesici sayo, kodwa inhlanganisela ngokuvamile inezakhiwo ezingcono. Izinto ezihlanganisiwe zinikeza izakhiwo eziphakeme kuma-alloys avamile wezinhlelo zokusebenza ezihlukahlukene njengoba zinokuqina okuphezulu, amandla nokumelana nokugqoka.

Ukuthuthukiswa kwalezi zinto kwaqala ngokukhiqizwa kwezinhlanganisela eziqiniswe nge-fiber-reinforced. Izindleko eziphezulu nobunzima bokucubungula lezi zinhlanganisela zikhawulele ukusetshenziswa kwazo futhi kwaholela ekuthuthukisweni kwezinhlanganisela ezingasaqinisiwe. Inhloso ehilelekile ekuklameni izinto eziyinhlanganisela ye-metal matrix ukuhlanganisa izici ezifiselekayo zezinsimbi nezitsha zobumba.

Nakuba ibizwa nge-hard metal, i-Tungsten Carbide empeleni iyinhlanganisela yezinto enezinhlayiya eziqinile ze-Tungsten Carbide ezishumekwe ku-matrix ethambile ye-metallic Cobalt.

Kungani izinhlanganisela zinamandla aphezuluth?

Izinhlanganisela zenziwe ngohlobo lwekhabhoni ebizwa ngokuthi i-graphene ehlanganiswe nensimbi yethusi, ekhiqiza into enamandla ngokuphindwe izikhathi ezingu-500 kunethusi iyodwa. Ngokufanayo, inhlanganisela ye-graphene ne-nickel inamandla angaphezu kuka-180 we-nickel. Ngokuqondene ne-fiberglass, yenziwe ngepulasitiki.

Yiziphi izigaba ezi-3 zezinhlanganisela?
Kulolu hlelo ngalunye, i-matrix ngokuvamile iyisigaba esiqhubekayo kuyo yonke ingxenye.

I-Polymer Matrix Composite (PMCs) ...

Inhlanganisela ye-Metal Matrix (MMCs) ...

I-Ceramic Matrix Composite (CMCs)

Uyini umehluko phakathi kwe-ceramic ne-composite?

Umehluko owodwa phakathi kwezinto ze-ceramic nezihlanganisiwe ukuthi amaceramic anokumelana kangcono nokugqokwa, izici zokushintshwa futhi anengcindezi encane ezinyo elizungezile emkhawulweni wezinyo lokubuyisela. I-Ceramics ilungele ama-inlay, ukubuyisela ukumbozwa kwe-cusp njengemiqhele nama-onlay, kanye nama-veneers amahle kakhulu.

Iyiphi into eyinhlanganisela elula kakhulu?

Ngokungeziwe ekubeni i-thermal conductive material emhlabeni, i-graphene iphinde ibe into encane kunazo zonke, elula futhi eqine kakhulu eyake yatholwa ngenxa yefomu layo lezinhlangothi ezimbili. Ngokusho kwe-CNN, inamandla aphindwe izikhathi ezingu-200 kunensimbi, futhi ilukhuni kunedayimane.

Yiziphi izinzuzo nezingozi ze-composite?

Nakuba ngokuvamile zibiza ngaphezu kokhuni, izinto eziyinhlanganisela zinikeza isithembiso sokuqina okukhulu nokunakekelwa okuncane.

Ingabe kukhona okungaklwebha i-tungsten carbide?

I-Tungsten carbide inobulukhuni obungu-9, ngokwalesi sikali, okusho ukuthi ingaklwebha amaminerali ayisishiyagalolunye kwayishumi futhi idayimane kuphela elingaklwebha i-tungsten carbide.

Ingabe i-tungsten carbide iyagqwala emanzini?

Ngenxa yokuthi ayikho i-ayoni ku-tungsten carbide, ngeke igxume nakancane (bona isihloko sethu esithi Ukunakekela Amathuluzi Anezinsimbi ukuze uthole ulwazi olwengeziwe mayelana nokukhipha ukugqwala kumapulangwe). Nokho, lokho akusho ukuthi i-carbide ayikwazi ukugqwala.

Uma unentshisekelo emikhiqizweni ye-tungsten carbide futhi ufuna ulwazi olwengeziwe nemininingwane, UNGAXHUMANA NATHI ngocingo noma nge-imeyili kwesokunxele, noma SITHUMELE IMEYILI ezansi kwaleli khasi.
