Astaamaha ugu muhiimsan eenano vanadium carbide ultrafine vanadium carbide budada loo diyaariyey iyada oo loo marayo hab gaar ah, nano vanadium carbide VC = 62.95, content carbon ee 22% ee budada biraha madow u eg, crystallization ee nidaamka kristal chloride ah nooca cubic crystal, lattice joogto ah 4.182 Å, karkaraya dhibic, barta dhalaalka 28000C, 39000C, xasiloonida kiimikada wanaagsan iyo waxqabadka heerkulka sare.Waxaa loo isticmaali karaa in lagu gooyo qalabka, biraha-samaynta warshadaha iyo tungsten carbide hadhuudh dalagyada hadhuudh, si weyn u hagaajin kara.Sida VC iyo carbide bir ah oo kale oo naadir ah ayaa lagu daray si loo xakameeyo korriinka hadhuudhka iyo hagaajinta qaab dhismeedka ururka oo ah ujeeddada ugu weyn, haddii ay tahay wax soo saarka hadhuudhka aan fiicneyn, sida qalabka macdanta ama baararka wareegsan, sida dabaylaha ultra-fine, waa inay doortaan karbides Fsss hooseeya ee biraha dhifka ah, carbide biraha naadir ah sababtoo ah qadarka yar ee lagu daray ayaa hadda bilaabaya in la hagaajiyo cabbirka hadhuudhka WC iyo hagaajinta doorka qaab dhismeedka ururka, sidaa darteed, waxaan rajeynayaa in lagu daro kala firidhsan ka sii badan. Haojiu Hang.Ulaha iyo daawaha kale ee ultra-fiican hadhuudh haddii lagu daro waa mid aad u qallafsan, laakiin formation of gal alloy aan qallafsanayn, aan ku haboonayn si loo hagaajiyo waxqabadka alaabta.Waxaan iibiyay budada nano vanadium carbide, cabbirka qayb ka mid ah nanoscale, saamiga lagu daray tobanka kun ee guud waxay si weyn u hagaajin kartaa waxqabadka walxaha.Vanadium carbide sida sifeeyaha hadhuudhka ah, ayaa si weyn loogu isticmaalay birta iyo warshadaha kale, nadiifinta sare, nano nano vanadium carbide, codsigeeda si loo sii ballaariyo horumarinta sayniska iyo tignoolajiyada, ayaa si weyn loogu isticmaalay carbide sibidhka iyo agabka catalytic meelo badan , waa isku darka horumarinta khayraadka vanadium iyo titanium iyo soo saarista heer muhiim ah oo qiimo sare leh oo qalab cusub.
Codsiyada
Qalabka goynta, warshadaha birta iyo wakiilka sifaynta hadhuudhka tungsten carbide, ayaa si weyn u wanaajin kara guryaha alloy-ga.
