Gutanga uruganda HW-D500C SiCNWs silicon karbide nanowires

Ibisobanuro bigufi:

Mubisanzwe bisanzwe bya ceramic matrix, HW-D500C SiCNWs silicon karbide nanowires iri munsi ya 10wt% byongeweho muri rusange. Muburyo bwo gutezimbere, birasabwa guhera kuri 1wt% hanyuma bigerageza buhoro buhoro no gukora neza.

Ibishoboka Ibikoresho bishimangirwa kandi bikaze, ibikoresho bya matrix na ceramic matrix compratifs bishimangirwa kandi bigakomezwa na silicon carbide nanowires byakoreshejwe cyane mumashini, inganda zimiti, ingabo zigihugu, ingufu, kurengera ibidukikije nizindi nzego.

Ibisobanuro:

Ibintu bifatika bya silicon karbide nanowire:

Cubic kristal, ni ubwoko bwa kirisiti isa na diyama.Nuburyo bumwe bwa kirisiti imwe ifite imbaraga nyinshi nuburyo bwogosha.Ifite ibikoresho byinshi byiza byubukanishi nkimbaraga nyinshi na modulus yo hejuru, nikimwe mubikoresho byiza bikomeza kandi bikaze.

Imiterere yimiti ya silicon karbide nanowires:

Kwambara birwanya, ubushyuhe bwo hejuru, kurwanya ihungabana ridasanzwe, kurwanya ruswa, kurwanya imirasire.

Icyerekezo cyingenzi cyo gukoresha silicon karbide nanowires:

1.SIC nanowires / ceramic matrix igizwe: SIC / TIC / WC / ALN / SI3N4 / TIN / AL2O3 / ZRO2 / ZRB2 nibindi

2.SIC nanowires / ibyuma bya matrix igizwe: AL / TI / NI nibindi

3.SIC nanowires / polymer ishingiye kubintu: Nylon / resin / rubber / plastike nibindi

Gutatanya hamwe ninyongera ya SiC Nanowires:

Gutatanya hamwe ninyongera ya SiC Nanowires (kubisobanuro gusa)
Basabwe gukwirakwiza ibitangazamakuru: amazi ya deioni, amazi yatoboye, Ethanol anhydrous, Ethylene glycol
Basabwe gutatanya: Polyethylene imine (PEI), polyide nonionic polyacry lamide (PAM), sodium pyrophosphate (SPP), twain 80, umukozi wa silicon compound, polyethylene glycol, sodium hexametaphosphate, sodium carboxymethyl selulose (CMC), nibindi.
Mubisanzwe bisanzwe bya ceramic matrix, silicon karbide nanowires iri munsi ya 10wt% byongeweho muri rusange.Mu nzira yo gutezimbere byihariye, birasabwa guhera kuri 1wt% hanyuma bigerageza buhoro buhoro no gukora neza.Ukurikije imyitozo yubushakashatsi, hejuru yongeweho ntabwo byanze bikunze aribyiza, bifitanye isano nibikoresho fatizo, ingano yibintu, ubushyuhe bwa sinteri, umubare wongeyeho urashobora kubona ingaruka nziza yo gukomera.

Nyuma yo kuvanga SiC nanowire yatatanye hamwe nifu ya ceramic, komeza utatanye mumasaha 1-12.Gukwirakwiza urusyo cyangwa uburyo bwo gukanika imashini birasabwa.Uburyo bwo gusya umupira biroroshye gutera nanowire kumeneka.

Niba kuvanga SiC nanowires nibikoresho bya matrix atari byiza cyane, sodium hexametaphosphate ya 1% ya misa ya SiCNW (cyangwa umubare muto wa isopropanol / ethanol) irashobora kongerwaho nkikwirakwiza kugirango habeho kuvanga uburinganire.

Nyuma yo gutatanya, gukama no kubura amazi bigomba gukorwa ako kanya.Suka ibishishwa mu cyombo gifite ahantu hanini kugirango ukwirakwize neza, kandi wongere aho hantu bizagenda byuka kandi bitume umwuma byoroshye.Ni ngombwa cyane kwirinda gusibanganya ibikoresho fatizo hagati ya nanowire na matrix.Ubushyuhe bwo gukama busabwa ni 110-160 ℃.
