Astaamaha ugu muhiimsan

Ultrafine nano silicon carbide, budada silikoon carbide by variable laser ion beam, kaydinta uumiga kiimikada by variable hadda, dheecaan koronto sare, si buuxda uga adkaan kartaa liidata ee dc arc koronto (jawaab aan ku filnayn, wasakhda sare ee alaabta, xasiloonida liidata ee alaabta).Nadiifin sare, qaybinta cabbirka qayb yar, meel sare oo gaar ah;Nano silicon carbide waxay leedahay wax qabad kiimikaad oo xasilloon, isugeyn sare oo kuleylka kuleylka ah (165 w / MK), isugeynta fidinta kuleylka yar, adkaanta sare, adkaanta mohs ilaa 9.5, microhardness 2840 ~ 3320 kg / waxay ahayd waxyaabaha ugu horreeya ee lagu daro abrasion u adkaysta, engegnaanteedu waxay u dhaxaysaa alumina isku dhafan iyo dheeman, xoogga farsamaysan ayaa ka sarreeya alumina isku dhafan;Nano silikoon carbide waxay leedahay conductivity kaamerada heer sare ah, sidoo kale waa nooc ka mid ah semiconductor, awood u adkaysiga oksaydhka heerkulka sare;Nano silikoon carbide xirashada, iska caabinta heerkulka sare, iska caabinta daxalka, caabbinta aashitada iyo dareeraha alkali, oo si weyn loogu isticmaalo rinjiga, rinjiga, kordhinta caabbinta xirashada.

Codsiga

1 wax ka beddelka xoogga sare ee naylon: budada nanometer SiC ee ku habboon walxaha polymer composite waa mid wanaagsan, kala firdhisanaan wanaagsan, oo lagu daro matrix wanaagsan, iyo naylon alloy oo la beddelay oo xoog xoog leh oo xoog leh oo ka badan 150% ka sarreeya kan caadiga ah ee PA6, xidho- waxqabadka iska caabinta ayaa kordhay in ka badan saddex jeer.Inta badan qaybaha polymer-ka ee gaashaaman ee daba-galka ah, qaybaha isteerinka baabuurta, mishiinnada dunta, guddiga dahaarka mishiinada macdanta, qaybaha tareenka hoostiisa heerkulka hoose cufnaanta sintering waa la gaarey;

2 wax ka beddelka caagagga injineernimada gaarka ah ee polyether ether ketone (PEEK) waxqabadka adkaysiga u adkaysta: ka dib markii la farsameeyo dusha sare ee nano silicon carbide, marka lagu daro tirada qiyaastii 5%, waxay si weyn u wanaajin kartaa oo kor u qaadi kartaa xidhashada PEEK (waxaa kordhay in ka badan 30% ;

3 ee codsiga nano silicon carbide ee taayirka caagga ah: ku darida 2% ama wax la mid ah nano silikon carbide iyada oo aan la beddelin kolajka qaabaysan wax ka beddelka, iyo iyada oo aan la dhimin waxqabadkeeda iyo tayada hoos dhismaha ay xirashada caabbinta waxaa lagu kordhin karaa 20% - 40 %.Intaa waxaa dheer, codsiga nano silikon carbide ee rullaluistemadka caag ah, filim fuser printer, sida xirashada caabbinta, kulaylka, caabbinta kulaylka iyo alaabta kale ee caag ah;

4 nanometer SiC daahan dusha biraha ka kooban: qaybaha nano-cabbirka qayb labaad hybrid qaybaha, nikkel sida biraha matrix ah, oogada birta si ay u sameeyaan cufnaanta sare, isku xidhka xoog aad u wanaagsan electrodeposition ka kooban, dusha birta leh adag (xiro) iyo antifriction ( is-saliid) sifooyin heerkul sare leh.Si weyn u wanaaji dahaarka isku dhafan ee microhardness, xidho caabbinta korodhka 2-3 jeer, hagaajinta nolosha adeegga ee 3-5 jeer, xoogga adhesion ee daahan iyo substrate kordhay 40%, daboolaya awoodda xoog leh, daahan labis, siman oo jilicsan;

Codsiyada 5 kale: dhoobada qaab dhismeedka sare ee qaab dhismeedka (sida tuubada gantaalaha, warshadaha nukliyeerka, iwm.), walxaha nuugaya, dufan dufan u adkaysta, suufyada bareegyada waxqabadka sare leh, adkaanta sare, xidhashada caabbinta dahaarka budada, dhoobada isku dhafan ee la xoojiyay iwm;In berrinkii dhismaha warshadaha aerospace, daahan functional, daahan ilaalinta, daahan alaabta nuugista, alaabta qarsoodiga ah, iwm .;Taangiyada iyo baabuurta gaashaaman ee gaashaaman;Qalabka goynta dhoobada, qalabka goynta iyo qalabka cabbiraadda oo dhinta;Sida isticmaalka gaarka ah ceramics qaab-dhismeedka, ceramics functional, ceramics injineernimada;Shidaalka;Walxaha kuleyliyaha korontada ee warshadaha korontada, koronto dhaliyaha fog.
