Izici eziyinhloko zeI-nano-titanium carbide, i-ultra-fine titanium carbide powder elungiselelwe ngendlela yenqubo ekhethekile, ukuhlanzeka okuphezulu, ububanzi bezinhlayiyana ezincane zokusabalalisa usayizi, indawo ethile ephezulu, umsebenzi ophezulu, izinga lokushisa eliphezulu, i-anti-oxidation, iwukugaya okuhle ukumelana ne-refractory. impahla, isetshenziswa kabanzi ku-carbide, gqoka izinto eziqinile ezingaphezulu;i-titanium carbide indawo encibilikayo engaba ngu-32 ℃, izingxenye ze-carbide, ezinobulukhuni obuphezulu, ukumelana nokugqwala, ukuzinza okuhle kokushisa, okusetshenziselwa ukukhiqiza izinto ezivimbela ukuguga, amathuluzi okusika, isikhunta, izinsimbi zensimbi ezincibilikayo nezinye izindawo;ngenxa yokuthi usayizi wezinhlayiyana ezincane ngakho-ke unomsebenzi ophezulu ongaphezulu, onokuhamba kahle kukagesi, ukungabi namandla kwamakhemikhali, nokusebenza okuhle kakhulu kanye nensimbi nensimbi;engeza izinkulungwane eziyishumi ze-nano-titanium carbide zinganciphisa izinga lokushisa le-titanium carbide ceramic sintering lama-degree angu-200, futhi lingacwengisiswa okusanhlamvu kwe-ceramic futhi kuthuthukise inqubo ye-ceramic sintering;I-nano-titanium carbide njenge-ceramic material eqiniswe ukuthuthukisa izakhiwo zemishini yensimbi, impahla ye-ceramic matrix kanye nezakhiwo zokuqhuba.
Izinhlelo zokusebenza
I-1 nm titanium carbide esetshenziswa ezingxenyeni ze-aerospace: kucatshangelwa i-refractory nano-carbides i-TiC ye-ZrC inephuzu lokuncibilika ngaphezu kuka-3000 ℃, inamandla amahle okushisa okuphezulu, nokuhambisana kahle ne-tungsten, i-coefficient efanayo yokwanda okushisayo, futhi inokungaphezu kwalokho. i-tungsten ngenani eliphansi kakhulu.I-Nano ye-TiCp / w kanye ne-ZrCp / w yamandla ayinhlanganisela enezinga lokushisa elikhulayo likhuphuka kancane kancane.I-Nano ye-TiCp/w ne-ZrCp/w ku-1000 ℃ no-800 ℃ ngokulandelana, amandla aphakeme kakhulu anyuswe ngokuphawulekayo uma kuqhathaniswa nokuqina kwezinga lokushisa elifanele legumbi.Khona-ke izinga lokushisa liyaqhubeka nokukhuphuka, ukuqina kwehle.Inhlanganisela yala mandla okushisa aphezulu angavamile, i-W the base body enezinga lokushisa ukuthuthukisa ukuguqulwa kwe-brittleness yepulasitiki, okwenza izinhlayiya ze-nano-TiC ne-ZrC ezingeni lokushisa eliphezulu le-plastic W-based body indima ethuthukisiwe ibaluleke nakakhulu, okuholela ebuhleni obuhle kakhulu. amandla okushisa aphezulu ezinto eziyinhlanganisela izinhlayiya ze-nano-TiC izinhlayiya ze-NONSTOICHIOMETRIC NANO ZrC I-substrate engu-W inokuthuthukiswa okungcono kwezinga lokushisa eliphezulu;
I-2 nm titanium carbide Ceramic foam: igwebu le-ceramic njengesihlungi ekufakweni koketshezi lingasuswa ngempumelelo indlela yokuhlunga iyanyakaziswa futhi i-adsorption.Isihlungi sidinga ukuqina kwamakhemikhali wento, ikakhulukazi embonini yensimbi sisebenzisa izimfuneko zokuhlunga zephuzu elincibilikayo eliphezulu, ngakho-ke iningi lalezo zinto ku-oxide, futhi livumelane nokuhlungwa kokuncibilika kwensimbi, ikakhulukazi ukuphishekela ukuthuthukiswa kokumelana nokushaqeka okushisayo.I-Nano titanium carbide Ceramic foam inamandla aphakeme, ubulukhuni, ukuguquguquka okushisayo, ukuqhutshwa kukagesi, nokumelana nokushisa nokugqwala kunegwebu le-oxide ceramic;
Isetshenziswa kakhulu ekwenzeni izinto ezingagugi emikhakheni eminingi yamathuluzi okusika, isikhunta, izinsimbi ezincibilikayo zensimbi nezinye izinto ezisobala ze-titanium carbide ceramics nezinto ezibonakalayo;I-titanium carbide abrasive ye-abrasives kanye nemboni e-abrasive ingenye ye-aluminium oxide, i-silicon carbide, i-boron carbide, impahla efanelekile ye-chromium oxide nezinye izinto zendabuko zokuthuthumela;Ukugaya i-nano-titanium carbide eqhathaniswa nedayimane yokwenziwa, kunciphisa kakhulu izindleko e-United States, Japan, Russia nakwamanye amazwe sekusetshenziswe kabanzi.I-Nano titanium carbide materials, ama-abrasives, amasondo okugaya kanye nemikhiqizo yamafutha okugaya ingathuthukisa kakhulu ukusebenza kahle kokugaya, futhi ithuthukise ukunemba kokugaya kanye nokuqedwa kwendawo.
4 inkambu ye-powder metallurgy: I-Nano-titanium carbide powder yokukhiqiza i-powder metallurgy ye-ceramics, izingxenye ze-carbide zezinto zokusetshenziswa, njengokudweba ngocingo kuyafa, i-carbide iyafa nokunye.I-Nano titanium carbide based cemented carbide inezici ezilandelayo: (1) ubulukhuni obuphezulu, ngokuvamile obufika ku-HRA90 ngenhla;(2) ukumelana nokugqoka, izinga eliphansi lokuguga;(3) izinga lokushisa eliphezulu namandla e-antioxidant;(4) conductivity ezinhle ezishisayo, okuhle amakhemikhali ukuzinza.
