Imibuzo malunga noComposite Materialskunye neTungsten Carbide

Izinto ezidibeneyo zizinto zobunjineli ezibalulekileyo ngenxa yeempawu zabo ezibalaseleyo zoomatshini. Ii-Composites zizinto apho iimpawu ezinqwenelekayo zezinto ezihlukeneyo zidibaniswe ngokuzibophezela ngomatshini kunye. Ilungu ngalinye ligcina ukwakheka kunye neempawu zalo, kodwa indibaniselwano ngokubanzi ineempawu ezingcono. Izinto ezidibeneyo zibonelela ngeempawu eziphezulu kwii-alloys eziqhelekileyo kwizicelo ezahlukeneyo njengoko zinobunzima obuphezulu, amandla kunye nokuxhatshazwa kokugqoka.

Ukuphuhliswa kwezi zixhobo kwaqala ngokuveliswa kwee-composites-fiber-reinforced composite. Iindleko eziphezulu kunye nobunzima bokusetyenzwa kwezi ngxubevange zithintele ukusetyenziswa kwazo kwaye kukhokelele kuphuhliso lwezihlanganisela eziye zaqiniswa ngokuqhubekayo. Injongo ebandakanyekayo ekuyileni izinto ezidibeneyo ze-metal matrix kukudibanisa iimpawu ezinqwenelekayo zesinyithi kunye neekeramics.

Nangona ibizwa ngokuba yintsimbi eqinileyo, iTungsten Carbide yimathiriyeli ehlanganisiweyo enamasuntswana aqinileyo eTungsten Carbide efakwe kwimatrix ethambileyo yeMetallic Cobalt.

Kutheni imidibaniso inamandla aphezuluth?

Imixube yenziwe ngohlobo lwekhabhoni ebizwa ngokuba yigraphene edityaniswe nobhedu lwesinyithi, ivelisa into eyomeleleyo ngokuphindwe kangangama-500 kunobhedu ngokwayo. Ngokufanayo, i-graphene kunye ne-nickel edibeneyo inamandla angaphezu kwamaxesha angama-180 e-nickel. Ngokuphathelele i-fiberglass, yenziwe ngeplastiki.

Zeziphi iindidi ezi-3 zemidibaniso?
Kwisixokelelwano ngasinye, i-matrix idla ngokuba sisigaba esiqhubekayo kulo lonke icandelo.

IPolymer Matrix Composite (PMCs) ...

IMetal Matrix Composite (MMCs) ...

I-Ceramic Matrix Composite (CMCs)

Uthini umahluko phakathi kwe-ceramic kunye ne-composite?

Omnye umahluko phakathi kweemathiriyeli zeseramic kunye ne-composite kukuba i-ceramics zinokungagugi ngcono, iimpawu zomatshini kwaye zinoxinzelelo oluncinci kwizinyo elijikelezileyo kumda wokubuyisela izinyo. I-Ceramics ilungile kwi-inlays, ukubuyisela i-cusp coverage efana nezithsaba kunye ne-onlay, kunye ne-veneers yobuhle obuphezulu.

Yeyiphi eyona imathiriyeli ilula eyomeleleyo?

Ukongeza ekubeni sesona sixhobo sisebenza ngethermally ehlabathini, i-graphene ikwayeyona imathiriyeli ibhityileyo, ikhaphukhaphu kwaye inamandla eyakhe yafunyanwa ngenxa yemo emacala mabini. Ngokutsho kwe-CNN, inamandla ngamaxesha angama-200 kunentsimbi, kwaye inzima kunedayimani.

Ziziphi iingenelo kunye neengozi zokudibanisa?

Nangona zihlala zibiza ngaphezu kweenkuni, izinto ezidibeneyo zinika isithembiso sokuqina okukhulu kunye nokugcinwa okuncinci.

Ngaba ikho into enokukrwela i-tungsten carbide?

I-Tungsten carbide inobulukhuni be-9, ngokwesi sikali, into ethetha ukuba iyakwazi ukukrwela iiminerali ezilithoba kwishumi kwaye idayimane kuphela enokukrwela i-tungsten carbide.

Ngaba i-tungsten carbide iyarusa emanzini?

Ngenxa yokuba akukho ntsimbi kwi-tungsten carbide, ayisokuze ivuthe (bona inqaku lethu elingokuKhathalela iziXhobo eziHlengiweyo ukuze ufumane ulwazi oluthe kratya malunga nokususa irusi kwipliers). Oko akuthethi, nangona kunjalo, ukuba i-carbide ayinakukwazi ukubola.

Ukuba unomdla kwiimveliso ze-tungsten carbide kwaye ufuna ulwazi oluthe kratya kunye neenkcukacha, ungaQHAGAMSHELANA NATHI ngefowuni okanye ngeposi ekhohlo, okanye SITHUMELE MAIL ezantsi kweli phepha.
