ufa wa nano-titanium carbide/ nano TiC 40nm 99.9%
Makhalidwe akuluakulu a nano-titanium carbide, ufa wa titanium carbide wabwino kwambiri wokonzedwa kudzera mu njira yapadera yopangira, chiyero chachikulu, kugawa tinthu tating'onoting'ono, malo apadera, ntchito yapamwamba pamwamba, kutentha kwakukulu, anti-oxidation, ndi chinthu chabwino chopukusira chosagwira ntchito, chimagwiritsidwa ntchito kwambiri ku carbide, kuvala zinthu zolimba kwambiri pamwamba; titanium carbide ili ndi malo osungunuka pafupifupi 32 ℃, zigawo za carbide, zokhala ndi kuuma kwakukulu, kukana dzimbiri, kukhazikika kwabwino kwa kutentha, zomwe zimagwiritsidwa ntchito popanga zipangizo zosavala, zida zodulira, nkhungu, zosungunulira zitsulo ndi madera ena; chifukwa tinthu tating'onoting'ono timakhala ndi ntchito yapamwamba pamwamba, yokhala ndi magetsi abwino, kusakhala ndi mphamvu zamagetsi, komanso magwiridwe antchito abwino komanso zitsulo zachitsulo; kuwonjezera pa 10,000 ya nano-titanium carbide kumatha kuchepetsa kutentha kwa titanium carbide ceramic sintering kwa madigiri 200, ndipo kumatha kukonzedwa tirigu wa ceramic ndikuwongolera njira yopangira ceramic sintering; nano-titanium carbide ngati chinthu cha ceramic cholimbikitsidwa kuti chiwongolere mawonekedwe a makina achitsulo, ceramic matrix ndi katundu woyendetsa.
1. nm titanium carbide yomwe imagwiritsidwa ntchito muzinthu zam'mlengalenga: Poganizira za nano-carbides zotsutsana ndi refractory TiC ya ZrC ili ndi malo osungunuka opitilira 3000 ℃, yokhala ndi mphamvu yabwino yotentha kwambiri, komanso yogwirizana bwino ndi tungsten, coefficient yofanana ya kutentha, ndipo ili ndi mphamvu yochulukirapo kuposa tungsten pamlingo wotsika kwambiri. Nano ya TiCp / w ndi ZrCp / w yokhala ndi mphamvu yophatikizana ndi kutentha kowonjezereka ikuwonjezeka pang'onopang'ono. Nano ya TiCp / w ndi ZrCp / w pa 1000 ℃ ndi 800 ℃ motsatana, mphamvu yayikulu kwambiri idawonjezeka kwambiri poyerekeza ndi mphamvu ya kutentha kwa chipindacho. Kenako kutentha kumapitirira kukwera, mphamvu idachepa. Zopangidwa ndi mphamvu yachilendo yotentha kwambiri, W maziko a thupi ndi kutentha kuti ziwongolere kusinthasintha kwa pulasitiki, zomwe zimapangitsa kuti tinthu ta nano-TiC ndi ZrC timene timakhala pa pulasitiki yotentha kwambiri tigwire ntchito yofunika kwambiri ya thupi lopangidwa ndi W, zomwe zimapangitsa kuti zinthu zophatikizika zikhale ndi mphamvu yotentha kwambiri komanso kutentha kwambiri, zomwe zimapangitsa kuti zinthu zophatikizika zikhale ndi mphamvu yotentha kwambiri.
2. nm titanium carbide ceramic thovu: thovu la ceramic ngati fyuluta mu madzi ophatikizidwa imatha kuchotsedwa bwino. Njira yosefera imasunthidwa ndikulowetsedwa. Fyuluta imafuna kukhazikika kwa mankhwala a chinthucho, makamaka mumakampani opanga zitsulo, imagwiritsa ntchito zofunikira pa fyuluta ya malo osungunuka kwambiri, motero zinthu zambiri zotere zimapita ku oxide, ndikuzolowera kusefa kwa chitsulo chosungunuka, makamaka kufunafuna kukana kutentha. Thovu la ceramic la Nano titanium carbide lili ndi mphamvu zambiri, kuuma, kutentha, kuyendetsa magetsi, komanso kukana kutentha ndi dzimbiri kuposa thovu la ceramic la oxide; Amagwiritsidwa ntchito kwambiri popanga zinthu zosatha m'magawo ambiri a zida zodulira, nkhungu, zosungunulira zitsulo zosungunuka ndi zina zowonekera za titanium carbide ndi zinthu zowala; titanium carbide abrasive ya abrasives ndi mafakitale a abrasive ndi njira ina m'malo mwa aluminiyamu oxide, silicon carbide, boron carbide, chinthu chabwino kwambiri cha chromium oxide ndi zinthu zina zachikhalidwe za abrasive; nano-titanium carbide grinding yofanana ndi diamondi yopangidwa, imachepetsa kwambiri mtengo ku United States, Japan, Russia ndi mayiko ena yakhala ikugwiritsidwa ntchito kwambiri. Zipangizo za nano titanium carbide, zopukutira, mawilo opukutira ndi zinthu zopangira mafuta opukutira zimatha kusintha kwambiri magwiridwe antchito a kugaya, ndikuwonjezera kulondola kwa kugaya ndi kumalizitsa pamwamba.
4. munda wa zitsulo za ufa: Ufa wa nano-titanium carbide wopangira zitsulo za ufa wa zoumbaumba, magawo a carbide a zipangizo zopangira, monga ma waya ojambulira, ma carbide ndi zina zotero. Carbide yopangidwa ndi simenti ya nano titanium carbide ili ndi makhalidwe awa: (1) kuuma kwakukulu, nthawi zambiri mpaka HRA90 pamwambapa; (2) kukana kutopa, kuchepa kwa kutopa; (3) kutentha kwambiri komanso mphamvu yoteteza ku ma antioxidants; (4) kutentha kwabwino, kukhazikika kwabwino kwa mankhwala.
