(I-Snbn yokuqhekeza iringiIveliswe nguWintrustek)

Ukuphosa okuqhubekayo okuqhubekayo kufuna i-molle eshukumayo kubamba okuyinqaba kwigrafiki yokufa kunye nendibano yokuphola ngaphandle kokusebenzisa amandla. Emva kokudlula kwigrafiki yokufa kunye nezinto ezininzi eziphetheyo, i-molle etyhidiweyo idlula iringi ebhaliweyo ebizwa ngokuba yi-ring yokutshaya ukuba ingene kwindawo eqinileyo. Kubalulekile ukuba iringi ye-ring igcine ingqibelelo yalo ngexesha lotshintsho lweqondo lobushushu olukhawulezileyo lwenzeka xa indawo eshushu inika indawo ebandayo (indawo eyomeleleyo). Kufuneka ivumele into efihlakeleyo ukuze iqhubeke iqukuqela ngokukhululekileyo ngaphandle kokunamathela okanye isakhiwo sendawo. I-rings i-rings yinxalenye ebalulekileyo yokuphosa ngokuthe tye, nangona kubonakala ngathi yinto engathethekiyo yeNdibano epheleleyo. Ubushushu bonke buya kulahleka kwimeko yokuba la macandelo aphumeleli okanye aphule, efaka umngcipheko wokhuseleko kwaye efuna isixa esikhulu sexesha lokuphumla kunye nokucoca.

Boron nitridebonakalisa ukunganyangeki kobushushu obuphezulu, ukwenziwa kombane, kunye nokuphumeza kwe-thermal. Ngo-1800 ° C, ubonakalisa uzinzo lwekhemikhali kwaye uhlala uzinzile ngokuchasene nekharbon kunye nekharbon monoxide. Ngapha koko, isinyithi esityhidiweyo, ityuwa etyhidiweyo, kunye ne-no-ne-non-bide slag ayiyi kulungisa. Ukongeza, i-bn inokuveliswa ibe ziziqwengana ezicocekileyo kwaye ziyakwazi ukutsha. I-roiting eqhubekayo yokwahlulahlula i-molten yensimbi yensimbi yenze i-boron witride rings. Kwimozulu enendawo ephezulu ye-vacuum, inokuqhubeka nokuthambisa ngelixa inamaqondo obushushu aphezulu.

Boron nitrideIzibonelelo ezisebenzayo

Intsimbi ephantsi yentsimbi
Ukwanda komhlaba okuphantsi kunye nokuphumelela okuthe tye okuqinisekileyo
Ukomelela ngokuthelekisa ngokuhambelana
Kakhulu ubushushu obuphezulu kukhuseleko olufanelekileyo kwi-Intert Gases

I-BN Ceramicineendidi ezininzi ezihlanganisiweyo,SnbnYenza ezona zilungileyo kwizixhobo eziqhubekayo zokuphosa:

Xa kuziwa ekuphoseni ngokuthe tyaba ngokuthe ngqo kwezinyithi ezingezozanto.I-Snbn (boron nitride + silicon nitride)I-ceramic ye-ceramics iqhuba kakuhle. Amakhonkco agqibeleleyo ngokuqinisekisa ukuba uqinisekile kwaye ukwahlukaniswa kwendlela yokuhamba kwensimbi kuba ayimithisi kwi-molten yesinyithi, i-oxidation-i-Inert, kunye ne-Intert.

Izibonelelo zeI-Snbn yokuqhekeza iringi

Ukunganyangeki kwe-oxidation: ukuya kuthi ga kwi-1000 ° C emoyeni
I-temp-temp enesitayile: kwi-vacuum okanye irhasi ye-inert, ukuya kuthi ga kwi-1700-1800 ° C
Ukungabeki
I-erosion kunye ne-corrosion: I-Asstands ezisebenzayo kwaye ziyanyangeka

Izibonelelo zeI-Snbn yokuqhekeza iringiXa kuthelekiswa ne-ratite

I-Snramic Deramic Ukophula amakhonkco, eyenzelwe iinkqubo zokuphosa iingqongqo, zenze ngcono kune-piles yegraphite kuba zikhululekile ngokupheleleyo kungcoliseko lwekhabhoni kwaye zichaze i-oxidetion evakalayo. Ubume babo obungabulaliyo okanye ubume booqiso phantsi kwesiqinisekiso sokuhamba ngebhayisikile esiphezulu sokugqiba kunye nokuhamba kwentsimbi egudileyo.
