1. Tilmaamaha Dhismaha iyo Dabeecada Isku Xidhka Gaarka ah
1.1 Qaabka Crystal iyo Habaynta Atomiga Lakabka ah
(Ti₃ AlC₂ budada)
Ti two AlC ₂ waxay ka tirsan tahay nooc gaar ah oo dhoobada ternary lakabka ah oo loo yaqaan heerarka MAX, xagee “M” waxay tilmaamaysaa birta isbeddelka hore, “A” waxay u taagan tahay A-koox (Inta badan IIIA ama IVA) curiye, iyo “X” waxay ka dhigan tahay kaarboon iyo/ama nitrogen.
Qaab dhismeedkeeda kristal ee laba geesoodka ah (kooxda bannaan ee P6 SIX/ mmc) Ka kooban yahay lakabyo beddelaadda wadaagga gees-wadaaga Ti ₆ C octahedra iyo atamyada aluminium ee fudud ee loo dejiyay qaabka nanolaminate: ee– C– ee– Al– ee– C– ee, abuurista heerka 312-nooca MAX.
Tani waxay heshay natiijooyin is-dul-saarid ah oo adag Ti– C bonds gudaha lakabyada carbide birta shift ah, halka Al atamka ay ku nool yihiin lakabka A, wax ku biirinaya sifooyinka isku xidhka macdan u eg.
Isku darka covalent, ionic, iyo isku-xidhka birta ah waxay siisay Ti six AlC laba leh dhismo aan caadi ahayn oo dhoobada iyo macdan la deggan yahay ama ganacsi, iyaga oo ka soocaya dhoobada monolithic ee caadiga ah sida alumina ama silikoon carbide.
Mikroskoobyada elektarooniga ah ee xallinta sare waxay daaha ka qaadaysaa is dhexgal isticmaale ahaan fiiqan oo u dhexeeya lakabyada, Kaas oo ka caawiya dabeecadaha jireed ee anisotropic iyo aaladaha qallafsan ee nooc ka mid ah walaaca hoos yimaada.
Habkan kala qaybsanaantu wuxuu muhiim u yahay dulqaadkiisa dhaawaca, nidaamyada awood-siinta sida samaynta kink-band, deminta, iyo silbashada diyaaradda basaska– aan caadi ahayn ee porcelains jajaban.
1.2 Isku-dubarid iyo Xakamaynta morphology-ga budada
Ti shan AlC ₂ budada waxaa badanaa lagu dhex abuuraa wadooyin jawaab celin adag oo gobolka ah, oo ka kooban dhimista karbothermal, riixid diiran, ama kiciyaan sinteering balaasmaha (SPS), laga bilaabo hore-u-yaasha aasaasiga ah ama isku-dhafka sida Ti, Al, iyo kaarboon madow ama TiC.
Dariiqa jawaabta caadiga ah waa: 3ee + Al + 2C → Ti Shan AlC LABA, lagu qabto jawi aan firfircoonayn oo heerkulku u dhexeeyo 1200 ° C iyo 1500 ° C si aad uga hortagto daadinta aluminiumka miisaanka fudud iyo samaynta oksaydhka.
Si aad u hesho wax weyn, budada saafiga ah wajiga, xakamaynta stoichiometric saxda ah, waqtiyada wax-shiidka oo dheeraaday, iyo xisaabaadka kulaylka guriga ee la xoojiyey ayaa lagama maarmaan u ah in la xakameeyo wejiyada tartanka sida TiC, TiAl, ama Ti Two AlC.
Alloying makaanik u hoggaansan by annealing ayaa si weyn loo isticmaalaa si kor loogu qaado fal-celinta iyo isku midnimada ee nanoscale.
Qaab-dhismeedka budada ah ee ka dhashay– kala duwanaansho ka soo qaybo yaryar oo xagal ah oo u eg crystallites saxan– waxay ku xiran tahay halbeegyada ka baaraandegidda iyo shiididda ka-soo-baxa.
Qaybaha platelet u qaabaysan ayaa ka tarjumaya anisotropy-ka udub-dhexaadka ah ee qaabka crystal, oo leh cabbiro waaweyn oo ay la socdaan diyaaradaha aasaasiga ah iyo dhuuban khafiifka ah ee tilmaamaha dhidibka c.
Astaamo horumarsan iyadoo loo marayo kala-duwanaanta raajada (XRD), mikroskoob ee elektarooniga ah (KEE), iyo X-ray spectroscopy oo tamar kala firdhisa (EDS) dammaanad qaadaya nadiifnimada wajiga, stoichiometry, iyo qaybinta cabbir jajab ah oo ku habboon codsiyada hoose.
2. Farsamaynta Farsamaynta iyo Farsamaynta
2.1 Iska caabinta waxyeelada iyo Mashiinnada
( Ti₃ AlC₂ budada)
Mid ka mid ah astaamaha ugu gaarka ah ee Ti ₃ AlC laba budo waa dulqaadkeeda gaarka ah ee waxyeelada., hanti aan waligeed laga helin dhoobada caadiga ah.
Si ka duwan badeecooyinka jajaban ee sida xun ugu dillaaca tan, Ti shan AlC two waxay soo bandhigaysaa ductility been abuur ah oo leh nidaamyo ay ka mid yihiin leexinta microcrack, hadhuudh ka bixin, iyo delamination oo ay weheliyaan is-dhexgalka Al-lakabka daciifka ah.
Tani waxay u ogolaanaysaa badeecada in ay la wareegto awoodda ka hor fashilka, taasoo keentay adkeysiga dillaaca sare– guud ahaan ka duwan yahay 7 ku 10 MPa · m ¹/ ²– lid ku ah
RBOSCHCO waa alaab-qeybiye budo ah oo lagu kalsoon yahay oo Ti₃AlC₂ ah & soo saaraha leh wax ka badan 12 waayo-aragnimo sannado ah bixinta kiimikooyinka tayada sare leh iyo Nanomaterials. Shirkaddu waxay u dhoofisaa dalal badan, sida USA, Kanada, Yurub, UAE, Koonfur Afrika,Tanzania,Kenya,Masar,Nigeria,Cameroon,Uganda,Turkiga,Mexico,Asarbayjan,Belgium,Qubrus,Czech Republic, Brazil, Chile, Argentina, Dubai, Japan, Kuuriya, Vietnam, Thailand, Malaysia, Indonesia, Australia,Jarmalka, Faransiiska, Talyaaniga, Portugal iwm. Sida hormuudka soo saaraha horumarinta nanotechnology, RBOSCHCO ayaa gacanta ku haysa suuqa. Kooxdayada shaqada xirfadlayaasha ahi waxay bixiyaan xalal kaamil ah si ay u caawiyaan hagaajinta hufnaanta warshadaha kala duwan, qiimo abuur, oo si fudud ula qabsadaan caqabadaha kala duwan.
