Usetyenziso olunokwenzeka Izinto ezidityanisiweyo eziqinisiweyo kunye neziqinisiweyo, i-Metal matrix kunye ne-ceramic matrix composites eziqiniswe kwaye ziqiniswe yi-silicon carbide nanowires zisetyenziswe ngokubanzi koomatshini, ishishini lemichiza, ukhuselo lwelizwe, amandla, ukukhuselwa kokusingqongileyo kunye nezinye iinkalo.

Inkcazo:

Iimpawu ezibonakalayo ze-silicon carbide nanowire:

Ikristale yeCubic, luhlobo lwekristale efana nedayimane.Yikristale ene-dimensional enye enamandla amakhulu kunye nokumila kweendevu.Ineempawu ezininzi ezigqwesileyo zoomatshini ezinje ngokuqina okuphezulu kunye nemodyuli ephezulu, eyona nto inamandla kunye nezixhobo eziqinisayo.

Iimpawu zeMichiza ye-silicon carbide nanowires:

Ukumelana nokunxiba, ukuxhathisa ubushushu obuphezulu, ukuxhathisa ukothuka okukhethekileyo, ukuxhathisa kwi-corrosion, ukumelana nemitha.

Izalathiso eziphambili ze-silicon carbide nanowires:

I-1.SIC i-nanowires/i-ceramic matrix composites: i-SIC/TIC/WC/ALN/SI3N4/TIN/AL2O3/ZRO2/ZRB2 njl.

I-2.SIC i-nanowires / i-metal matrix composites: AL / TI / NI njl

3.SIC iinanowires/ipolymer esekwe imidibaniso:Inayiloni/iresin/irabha/iplastiki njl.

Ukusasazwa kunye nemali eyongezelelweyo ye-SiC Nanowires:

Ukusasazwa kunye nemali eyongezelelweyo ye-SiC Nanowires (ngokubhekiselele kuphela)
Amajelo osasazo acetyiswayo: amanzi adiyiweyo, amanzi adityanisiweyo, i-anhydrous ethanol, i-ethylene glycol
I-dispersant ecetyiswayo: i-polyethylene imine (PEI), i-nonionic polyacry lamide (PAM), i-sodium pyrophosphate (SPP), i-twoin 80, i-silicon compound coupling agent, i-polyethylene glycol, i-sodium hexametaphosphate, i-sodium carboxymethyl cellulose (CMC), njl.
Kwiicomposites ze-ceramic matrix eziqhelekileyo, i-silicon carbide nanowires engaphantsi kwe-10wt% iyongezwa ngokubanzi.Ngokwendlela yovavanyo, okukhona isixa sokongeza asiyonto ibhetele, sinxulumene nemathiriyeli ekrwada, ubungakanani bezinto eziphathekayo, ubushushu be-sintering, isixa esifanelekileyo sokongeza sinokufumana eyona mpembelelo intle yokuqina.

Emva kokuxuba i-SiC nanowire slurry ehlakaziweyo kunye ne-ceramic powder, qhubeka uhlakaza iiyure eziyi-1-12.Ukusasazwa kwelitye lokusila okanye indlela yokuvuselela ngoomatshini iyacetyiswa.Indlela yokugaya ibhola kulula ukwenza ukuba i-nanowires iphule.

Ukuba ukuxutywa kwe-SiC nanowires kunye nezixhobo ze-matrix azilungile kangako, i-sodium hexametaphosphate ye-1% yobunzima be-SiCNW (okanye i-isopropanol / ethanol encinci) inokudibaniswa njenge-dispersant ukuphucula ukufana kokuxuba.

Emva kokusabalalisa, ukomisa kunye nokuphelelwa ngamanzi emzimbeni kufuneka kuqhutywe ngokukhawuleza.Thela i-slurry kwisitya esinendawo enkulu ukuze usasazeke, kwaye ukwandisa indawo iya kunyuka kwaye ikhuphe kalula.Kubaluleke kakhulu ukuphepha ukuchithwa kwezinto eziluhlaza phakathi kwe-nanowires kunye ne-matrix.Ubushushu obucetyiswayo bokomisa yi-110-160℃.
