Iimpawu eziphambili zeI-nano-titanium carbide, i-ultra-fine titanium carbide powder elungiselelwe ngendlela ekhethekileyo, ukucoceka okuphezulu, uluhlu oluncinci lokusabalalisa ubungakanani bamasuntswana, indawo ethile ephezulu, umsebenzi ophezulu, ubushushu obuphezulu, i-anti-oxidation, yinto efanelekileyo yokugaya i-refractory-resistant. izinto eziphathekayo, zisetyenziswa ngokubanzi kwi-carbide, zinxibe izinto ezinzima kakhulu ngasentla;i-titanium carbide indawo yokunyibilika malunga ne-32 ℃, amacandelo e-carbide, enobulukhuni obuphezulu, ukuxhathisa ukubola, ukuzinza okuhle kwe-thermal, esetyenziselwa ukuvelisa izinto ezinqabileyo zokunxiba, izixhobo zokusika, ukubumba, ukunyibilika kwesinyithi kunye nezinye iindawo;ngenxa yokuba ubungakanani bamasuntswana amancinci kwaye ke ngoko banomsebenzi omphezulu ophezulu, kunye nokuhanjiswa kombane okuhle, ukunganyaniseki kweekhemikhali, kunye nokusebenza okugqwesileyo kunye nentsimbi kunye neentsimbi zetsimbi;yongeza ishumi lamawaka le-nano-titanium carbide inokunciphisa i-titanium carbide i-ceramic sintering ubushushu be-200 degrees, kwaye inokucocwa iinkozo ze-ceramic kunye nokuphucula inkqubo ye-ceramic sintering;I-nano-titanium carbide njengento ye-ceramic eqiniswe ukuphucula iimpawu ze-mechanical zetsimbi, izinto ze-ceramic matrix kunye neempawu zokuqhuba.
Usetyenziso
I-1 nm titanium carbide esetyenziswa kwizixhobo ze-aerospace: kuthathelwa ingqalelo i-nano-carbides ye-Refractory i-TiC ye-ZrC inendawo yokunyibilika ngaphezu kwe-3000 ℃, inamandla alungileyo obushushu obuphezulu, kunye nokuhambelana kakuhle ne-tungsten, i-coefficient efanayo yokwandiswa kwe-thermal, kwaye ingaphezulu tungsten kuxinaniso olusezantsi kakhulu.I-Nano ye-TiCp / w kunye ne-ZrCp / w amandla adibeneyo kunye nokwanda kweqondo lobushushu ukunyuka ngokuthe ngcembe.I-Nano ye-TiCp / w kunye ne-ZrCp / w kwi-1000 ℃ kunye ne-800 ℃ ngokulandelanayo, amandla aphezulu anyuswe ngokuphawulekayo xa kuthelekiswa nobukhulu beqondo lokushisa elihambelanayo.Imidibaniso yala mandla obushushu obuphezulu obungaqhelekanga, isiseko somzimba esineqondo lobushushu ukuphucula ukuguquguquka okuguquguqukayo kweplastiki, okwenza amasuntswana e-nano-TiC kunye ne-ZrC kubushushu obuphezulu beplastiki esekwe kwindima ephuculweyo yomzimba ebaluleke ngakumbi, okukhokelela ekubeni kugqwese. amandla aphezulu obushushu bemathiriyeli edibeneyo ye-nano-TiC amasuntswana e-NONSTOICHIOMETRIC NANO ZrC amasuntswana e-W substrate anokwandiswa kobushushu obuphezulu;
I-2 nm i-titanium carbide igwebu le-ceramic: i-foam ye-ceramic njengesihluzo ku-fluid inclusions inokususwa ngokufanelekileyo indlela yokucoca ivuselelwe kunye ne-adsorption.Isihluzi sifuna uzinzo lwemichiza yesixhobo, ngakumbi kwishishini lesinyithi lisebenzisa iimfuno zokucoca indawo ephezulu yokunyibilika, kwaye ke ngoko uninzi lwemathiriyeli enjalo kwi-oxide, kunye nokuziqhelanisa nokuhluzwa kokunyibilika kwesinyithi, ngakumbi ukusukela. ukuphuculwa kokuxhathisa ukothuka kwe-thermal.I-Nano titanium carbide i-ceramic foam inamandla aphezulu, ukuqina, ukuhanjiswa kwe-thermal, ukuqhutyelwa kombane, kunye nokushisa kunye nokumelana nokushisa kune-oxide ye-ceramic foam;
Isetyenziswe ngokubanzi ekwenzeni izinto ezinqabileyo zokunxiba kwiinkalo ezininzi zezixhobo zokusika, ukubumba, ukunyibilika kweentsimbi zentsimbi kunye nezinye ii-ceramics ze-titanium carbide ezicacileyo kunye nezinto ezibonakalayo;I-titanium carbide i-abrasive ye-abrasives kunye ne-abrasive industry ingenye ye-aluminium oxide, i-silicon carbide, i-boron carbide, into efanelekileyo ye-chromium oxide kunye nezinye izinto zendabuko ezinqabileyo;I-nano-titanium carbide yokugaya ifaniswa nedayimani yokwenziwa, inciphisa kakhulu iindleko e-United States, eJapan, eRashiya nakwamanye amazwe sele isetyenziswe ngokubanzi.I-Nano titanium carbide materials, i-abrasives, amavili okugaya kunye nemveliso ye-ointment yokugaya inokuphucula kakhulu ukugaya, kunye nokuphucula ukuchaneka kokusila kunye nokugqiba umphezulu.
I-4 intsimi ye-metallurgy ye-powder: I-Nano-titanium carbide powder yokuvelisa i-metallurgy ye-ceramics, iinxalenye ze-carbide zezinto eziluhlaza, ezifana nomzobo wocingo uyafa, i-carbide iyafa njalo njalo.I-Nano titanium carbide esekelwe kwi-cemented carbide inezi mpawu zilandelayo: (1) ubunzima obuphezulu, ngokubanzi ukuya kwi-HRA90 ngasentla;(2) ukuxhathisa ukunxiba, izinga eliphantsi lokunxiba;(3) ubushushu obuphezulu kunye nomthamo we-antioxidant;(4) Ukuqhuba kakuhle kwe-thermal, ukuzinza okuhle kweekhemikhali.
