Astaamaha ugu muhiimsan ee nano-titanium carbide, budada karboide titanium-ka aadka u fiican ee lagu diyaariyey hab gaar ah oo habka loo maro, daahirnimo sare, kala duwanaansho yar oo qaybinta walxaha, bedka dusha sare ee gaarka ah, dhaqdhaqaaqa dusha sare, heerkulka sare, ka-hortagga oksaydhka, waa walax shiidid oo wanaagsan oo u adkaysta iska caabbinta, si weyn ayaa loogu dabaqaa carbide-ka, xirashada walxaha aadka u adag ee kor ku xusan; titanium carbide barta dhalaalka ee qiyaastii 32 ℃, qaybaha carbide-ka, oo leh adkaansho sare, iska caabin daxaleed, xasillooni kuleyl oo wanaagsan, oo loo isticmaalo soo saarista agabka u adkaysta xirashada, qalabka jarista, caaryada, dhalaalinta biraha iyo meelaha kale; sababtoo ah cabbirka walxaha yar sidaas darteedna waxay leeyihiin firfircooni dusha sare ah, oo leh koronto wanaagsan, firfircooni kiimiko, iyo waxqabad aad u wanaagsan iyo sidoo kale birta iyo birta; ku dar toban kun oo carbide nano-titanium ah waxay yareyn kartaa heerkulka sintering dhoobada titanium carbide ee 200 digrii, waxaana lagu sifeyn karaa hadhuudhka dhoobada ah waxayna hagaajin kartaa habka sintering dhoobada; nano-titanium carbide oo ah walax dhoobo ah oo lagu xoojiyay si loo hagaajiyo sifooyinka farsamada ee birta, walxaha matrix dhoobada iyo sifooyinka gudbiyaha.
1. nm titanium carbide oo loo isticmaalo qaybaha hawada sare: iyadoo la tixgelinayo nano-carbides-ka aan la qabsan karin TiC ee ZrC waxay leedahay dhibic dhalaalaysa oo ka sarreysa 3000 ℃, oo leh xoog heerkul sare oo wanaagsan, iyo iswaafajin wanaagsan oo leh tungsten, oo ah isku-darka isku-dhafka ah ee ballaarinta kulaylka, waxayna leedahay wax ka badan tungsten cufnaan aad u hooseysa. Nano ee TiCp / w iyo ZrCp / w xoog isku-dhafan oo leh heerkul kordhaya ayaa si tartiib tartiib ah u kordha. Nano ee TiCp / w iyo ZrCp / w 1000 ℃ iyo 800 ℃ siday u kala horreeyaan, xoogga ugu sarreeya ayaa si weyn loo kordhiyay marka la barbar dhigo xoogga heerkulka qolka ee u dhigma. Kadib heerkulku wuu sii kordhayaa, xoogga ayaa hoos u dhacay. Isku-darka xoogga heerkulka sare ee qalaad, W jirka salka leh heerkulka si loo hagaajiyo beddelka jajabnaanta ee balaastikada, taasoo ka dhigaysa walxaha nano-TiC iyo ZrC ee balaastikada heerkulka sare leh doorka la xoojiyay ee jirka ku salaysan W xitaa mid aad u muhiim ah, taasoo keentay xoog heerkul sare oo aad u fiican oo walxaha isku-dhafan ah Walxaha nano-TiC ee aan AHAYN NANO Walxaha ZrC ee W substrate waxay leeyihiin kor u qaadis heerkul sare oo wanaagsan;
2. Xumbo dhoobada ah oo ah nm titanium carbide: xumbo dhoobada ah oo ah shaandho ku jirta dareeraha ayaa si wax ku ool ah looga saari karaa habka shaandhaynta waa la kiciyaa oo la nuugaa. Shaandhaynta waxay u baahan tahay xasilloonida kiimikada ee walaxda, gaar ahaan warshadaha birta waa in la isticmaalo shuruudaha shaandhada ee dhibicda dhalaalka sare, sidaas darteedna inta badan walxahaas oo kale oksaydhka, iyo in la qabsado shaandhaynta dhalaalka birta, inta badan raadinta hagaajinta iska caabbinta shoogga kulaylka. Xumbo dhoobada ah oo ah nano titanium carbide waxay leedahay xoog sare, adkaansho, gudbin kuleyl, gudbin koronto, iyo iska caabbinta kulaylka iyo daxalka marka loo eego xumbo dhoobada oksaydhka; Si ballaaran ayaa loogu isticmaalaa soo saarista agabyada u adkaysta xirashada ee goobo badan oo qalabka jarista, caaryada, dhalaalinta biraha iyo dhoobada kale ee hufan ee titanium carbide iyo agabka indhaha; xoqidda titanium carbide ee xoqidda iyo warshadaha xoqidda waa beddel u ah aluminium oksaydh, silicon carbide, boron carbide, oo ah walax ku habboon oksaydhka chromium iyo agabyada kale ee xoqidda dhaqameed; shiididda nano-titanium carbide oo la barbar dhigi karo dheemanka synthetic, si weyn ayuu u yareeyaa kharashka Mareykanka, Japan, Ruushka iyo dalal kale ayaa si ballaaran loo isticmaalay. Qalabka birta ah ee Nano titanium carbide, xoqidda, giraangiraha shiididda iyo alaabada saliidda shiididda ayaa si weyn u wanaajin kara hufnaanta shiididda, waxayna hagaajin karaan saxnaanta shiididda iyo dhammaystirka dusha sare.
4. Beerta birta budada ah: Budada carbide-ka ee Nano-titanium ee loogu talagalay soo saarista birta budada ah ee dhoobada, qaybaha carbide-ka ee walxaha ceeriin ah, sida qalabka sawir-qaadista siligga, qalabka carbide-ka iyo wixii la mid ah. Karbohaydraytka sibidhka ah ee ku salaysan nano titanium carbide wuxuu leeyahay sifooyinka soo socda: (1) adkaansho sare, guud ahaan ilaa HRA90 ee kor ku xusan; (2) iska caabinta xirashada, heerka xirashada oo hooseeya; (3) heerkulka sare iyo awoodda antioxidant-ka; (4) dabacsanaanta kulaylka wanaagsan, xasilloonida kiimikada oo wanaagsan.
