Sihlinzeka ngokuhlanzeka okuphezulu kwe-Nano Silicon carbide powder.Lungisa imikhiqizo ye-alloy yengxenye ngokuvumelana nezidingo zekhasimende

Izici eziyinhloko

I-Ultrafine nano silicon carbide, i-silicon carbide powder by variable current laser ion beam, i-chemical vapor deposition by variable current, high voltage discharge, ingakunqoba ngokugcwele ukushiyeka kwe-dc electric arc (impendulo enganele, ukungcola komkhiqizo ophezulu, ukuzinza okubi kwemikhiqizo).Ukuhlanzeka okuphezulu, ukusabalalisa usayizi wezinhlayiyana ezincane, indawo ethile ephezulu;I-Nano silicon carbide inokusebenza kwamakhemikhali okuzinzile, i-coefficient ephezulu ye-thermal conductivity (165 w/MK), i-coefficient encane yokunweba okushisayo, ukuqina okuphezulu, ubulukhuni be-mohs bufika ku-9.5, ubuncane be-microhardness obungu-2840 ~ 3320 kg / kwakuyizithasiselo zokuqala ezimelana ne-abrasion, ubulukhuni bayo buphakathi kwe-alumina ehlanganisiwe nedayimane, amandla emishini aphakeme kune-alumina ehlanganisiwe;I-Nano silicon carbide ine-conductivity enhle kakhulu yokushisa, futhi iwuhlobo lwe-semiconductor, engakwazi ukumelana nokushisa okuphezulu kwe-oxidation;I-Nano silicon carbide wear-resisting, ukumelana nokushisa okuphezulu, ukumelana nokugqwala, ukumelana ne-asidi ne-alkali solvent, esetshenziswa kabanzi kupende, upende, kwandisa ukumelana nokugqokwa.

Ukusetshenziswa

Impahla enayiloni enamandla angu-1 eshintshiwe: izimpushana ze-nanometer SiC ekuhambisaneni kwezinto ezihlanganisiwe ze-polymer zinhle, zihlakazeka kahle, futhi zihlanganiswe ne-matrix enhle, kanye nengxubevange enayiloni eguquliwe yamandla amakhulu okudonsa ngamandla angaphezu kuka-150% ngaphezu kwaleyo ye-PA6 evamile, ukugqokwa- ukusebenza ukumelana kwenyuke izikhathi ezingaphezu kwezintathu.Ikakhulukazi for the armored zilandelwa imoto polymer izingxenye, izimoto eziqondisa izingxenye, imishini yendwangu, yezimayini imishini ujenga ibhodi, izingxenye isitimela ngaphansi lokushisa low sintering densification kufinyelelwa;

I-2 modified special engineering plastics polyether ether ketone (PEEK) ukusebenza kokumelana nokugqoka: ngemva kokucubungula ubuso be-nano silicon carbide, lapho ukwengeza ubuningi cishe ku-5%, kungathuthukisa kakhulu futhi kukhuphule ukugqokwa kwe-PEEK (kukhuphuke ngaphezu kuka-30% );

I-3 yokusetshenziswa kwe-nano silicon carbide ethayini lenjoloba: ukwengeza u-2% noma ngaphezulu we-nano silicon carbide ngaphandle kokushintsha ifomula eguquliwe ye-collagen, futhi ngaphandle kokunciphisa ukusebenza kwayo nekhwalithi ngaphansi kwesisekelo sokumelana kwayo nokugqoka kungakhuphuka ngo-20% - 40 %.Ngaphezu kwalokho, ukusetshenziswa kwe-nano silicon carbide ku-rubber roller, ifilimu yephrinta fuser, njengokumelana nokugqoka, ukushisa, ukumelana nokushisa neminye imikhiqizo yerabha;

I-4 nanometer SiC eyinhlanganisela yensimbi ehlanganisa indawo yensimbi: izinhlayiya zesikali se-nano-scale izinhlayiya ze-hybrid yesibili, i-nickel njengensimbi ye-matrix, indawo yensimbi ukuze yakhe ukuminyana okuphezulu, amandla okubopha okuhle kakhulu okuyinhlanganisela ye-electrodeposition, ingaphezulu lensimbi eliqinile (ukuguga) kanye nokuphikisana ( self-lubricating) izici ezimelana nezinga lokushisa eliphezulu.Thuthukisa kakhulu ukuqina kokuqina kokuqina kwenhlanganisela, ukumelana nokugqoka kukhuphuka izikhathi ezingama-2-3, thuthukisa impilo yesevisi izikhathi ezi-3-5, amandla okunamathela we-coating kanye ne-substrate anda ngo-40%, ikhono lokumboza liqinile, ukunamathela okufanayo, okubushelelezi futhi okubucayi;

Ezinye izinhlelo zokusebenza ezi-5: izinto zobumba ezisebenza kahle kakhulu (njenge-rocket nozzle, imboni yenuzi, njll.), izinto ezimuncayo, amafutha okugcoba angagugi, amabhuleki amabhuleki asebenza kahle kakhulu, ukuqina okuphezulu, ukumelana nokugqokwa kwezindwangu zempushana, ukuqina okuqinile kwe-ceramic ehlanganisiwe. , njll.;Emkhakheni wesakhiwo semboni ye-aerospace, ukugqoka okusebenzayo, ukumboza okuvikelayo, izinto ezibambayo zokugqoka, izinto eziyimfihlo, njll.;Amathangi nezimoto ezihlomile izikhali zokuzivikela;Ukuze ithuluzi lokusika le-ceramic, ithuluzi lokusika kanye nethuluzi lokulinganisa bese uyafa;Njengokusetshenziswa okukhethekile i-ceramics yesakhiwo, i-ceramics esebenzayo, i-ceramics yobunjiniyela;Ukuthungela;Izinto zokushisa zikagesi zezimboni zikagesi, ijeneretha ekude ye-infrared.
