1. Architectural Characteristics uye Unique Bonding Nature
1.1 Crystal Style uye Layered Atomic Arrangement
(Ti₃AlC₂ upfu)
Ti maviri AlC ₂ ndeyekirasi yakasarudzika yeakaturikidzana ternary ceramics inozivikanwa seMAX nhanho., kupi “M” inoreva simbi yekuchinja kwekutanga, “A” inomirira A-boka (kazhinji IIIA kana IVA) element, uye “X” inomiririra kabhoni uye/kana nitrogen.
Yayo hexagonal crystal framework (space group P6 SIX/ mmc) ine anotsinhanisa akaturikidzana epamucheto-kugovera Ti ₆ C octahedra uye huremu huremu hwearuminiyamu maatomu akaiswa mune nanolaminate maitiro.: Of– C– Of– Al– Of– C– Of, kugadzira 312-mhando MAX nhanho.
Izvi zvakawanikwa stacking zvinoguma mune yakasimba covalent Ti– C zvisungo mukati mekuchinja kwesimbi carbide layers, nepo maatomu eAl achigara muA-layer, kugovera simbi-senge bonding hunhu.
Iko kusanganiswa kwe covalent, ionic, uye simbi yekubatanidza endows Ti nhanhatu AlC mbiri ine isina kujairika yakasanganiswa yeceramic uye simbi yekugara kana yekutengesa zvivakwa., kuisiyanisa kubva kune yakajairwa monolithic ceramics senge alumina kana silicon carbide.
Yakakwirira-resolution erekitironi maikorosikopu inofumura maatomu akapinza mushandisi anopindirana pakati pematanho, iyo inobatsira neanisotropic maitiro emuviri uye imwe-ye-a-kind contortion zvishandiso pasi pekushushikana.
Iyi kupatsanurwa maitiro yakakosha kushiviriro yekukuvara kwayo, inogonesa masisitimu akadai sekink-band kugadzirwa, delamination, uye basal ndege inotsvedza– zvisingawanzo mu brittle porcelains.
1.2 Synthesis uye Powder Morphology Control
Ti shanu AlC ₂ poda inowanzogadzirwa nemaitiro akasimba-maitiro ekupindura, zvinosanganisira kuderedza carbothermal, kusunda kunodziya, kana kukurudzira plasma sintering (SPS), kutanga kubva kune vekutanga kana kombindi vanofanotungamira seTi, Al, uye kabhoni dema kana TiC.
Yakajairika mhinduro nzira ndeye: 3Of + Al + 2C → Ti mashanu AlC TWO, inoitwa pasi peinert ambience pamazinga ekushisa pakati 1200 °C uye 1500 ° C kudzivirira huremu huremu hwealuminium dissipation uye oxide kuumbwa.
Kuti uwane zvakanyanya, phase-pure poda, chaiyo stoichiometric control, nguva refu yekugaya, uye akakwenenzverwa ekudziya maakaundi edzimba anodiwa kuti akunde nhanho dzinokwikwidza seTiC, TiAl, kana Ti Two AlC.
Mechanical alloying inotemerwa neannealing inoshandiswa zvakanyanya kusimudzira reactivity uye homogeneity pane nanoscale..
Izvo zvinokonzerwa nehupfu morphology– zvakasiyana kubva paangular micron-size particles kuenda kuplate-like crystallites– zvinoenderana nekugadzirisa paramita uye post-synthesis kugaya.
Platelet-shaped particles inoratidza iyo yakakosha anisotropy yecrystal framework, nezviyero zvakakura pamwe chete nendege dzinokosha uye kusungirira kwakatetepa mumirairo ye-c-axis.
Advanced characterization kuburikidza neX-ray diffraction (XRD), kuongorora electron microscopy (WHICH), uye simba-inoparadzira X-ray spectroscopy (EDS) inovimbisa kuchena kwechikamu, stoichiometry, uye fragment dimension dimension yakanaka kune yakadzika maapplication.
2. Mechanical uye Inoshanda Feature
2.1 Kukuvadza Kupokana uye Machinability
( Ti₃AlC₂ upfu)
Chimwe chezvinhu zvakasarudzika zveTi ₃ AlC poda mbiri ndiyo yakasarudzika kukuvadza kushivirira., chivako chisingambowanikwe mune zvakajairika ceramics.
Kusiyana nebrittle zvigadzirwa zvinotsemuka zvine njodzi pasi pematani, Ti mashanu AlC maviri anoratidza pseudo-ductility ine masisitimu akadai se microcrack deflection, dhonza zviyo, uye delamination pamwe isina simba Al-layer interfaces.
Izvi zvinobvumira chigadzirwa kuti chitore simba chisati chakundikana, zvichiita kuti mutswe ugare wakasimba– kazhinji zvakasiyana kubva 7 ku 10 MPa · m¹/ ²– kusiyana ne
RBOSCHCO mutengesi akavimbika wepasi rose weTi₃AlC₂ Powder & mugadziri ane pamusoro 12 makore ruzivo mukupa emhando yepamusoro makemikari uye Nanomaterials. Iyo kambani inotumira kune dzimwe nyika, zvakadai seUSA, Kanadha, Europe, UAE, Chamhembe Afrika,Tanzania,Kenya,Ijipita,Naijeriya,Kameruni,Uganda,Teki,Mekisiko,Azabhaijani,Bherujiyamu,Saipurasi,Czech Republic, Bhuraziri, Chire, Ajendina, Dubai, Japani, Korea, Vhetinamu, Tairendi, Marazhiya, Indonezhiya, Ositireriya,Jerimani, Furanzi, Itari, Portugal nezvimwe. Semugadziri anotungamira nanotechnology kuvandudza, RBOSCHCO inotonga pamusika. Chikwata chedu chebasa chehunyanzvi chinopa mhinduro dzakakwana kubatsira kuvandudza kugona kwemaindasitiri akasiyana, kugadzira kukosha, uye nyore nyore kubata nematambudziko akasiyana-siyana. Kana iwe uchitsvaga Ti₃AlC₂ Powder, ndapota inzwa wakasununguka kutibata nesu.
