Ityhubhu ye-ceramic ye-silicon carbide enamandla aphezulu ye-SIC eneentlobo ezahlukeneyo zokumelana nomlilo okwenziwe ngokwezifiso

Ityhubhu ye-ceramic ye-silicon carbide enamandla aphezulu ye-SIC Iindidi ezahlukeneyo zokumelana nomlilo ezenzelwe wena Umfanekiso obonisiweyo

Inkcazo emfutshane:

Ityhubhu ye-ceramic ye-silicon carbide luhlobo lombhobho owenziwe nge-silicon carbide (SiC) njengeyona nto iphambili kwizixhobo ze-ceramic. Inkqubo yokuvelisa ibandakanya uqwalaselo lwe-powder, ukulungiswa kwesixhobo, ukuzaliswa kwe-powder, ukucinezelwa kwe-isostatic ebandayo, ukugqitywa kokusika i-core kunye nokusila kobushushu obuphezulu. Lo mbhobho unoxinano oluphezulu, ukuchaneka okuphezulu kwe-machining kunye nesakhiwo esifanayo, esinokuhlangabezana neemfuno zeendawo ezichanekileyo, ezifana noshishino lwenyukliya.

2. Ukumelana nokugqwala: Ukumelana kwayo nokugqwala okugqwesileyo kuyenza ifaneleke kwiindawo ezinomhlwa ophezulu kunye nokuguguleka okukhulu.
3. I-coefficient ephantsi yokungqubana: ityhubhu ye-ceramic ye-silicon carbide ine-coefficient ephantsi yokungqubana, efanelekileyo kwiimeko apho ukungqubana kufuneka kuncitshiswe.
4. Ukuqhuba okuphezulu kobushushu: ityhubhu ye-silicon carbide ceramic inokuqhuba okuphezulu kobushushu, inokudlulisa ubushushu ngempumelelo.
5. Iipropati ze-Antioxidant: Kwiindawo ezinobushushu obuphezulu, iityhubhu ze-silicon carbide ceramic zibonisa iipropati ze-antioxidant ezibalaseleyo.

Izicelo eziphambili:

1. Ifayibha yesafire eqhelekileyo: Uluhlu lobubanzi ludla ngokuba phakathi kwe-75 kunye ne-500μm, kwaye ubude buyahluka ngokwesayizi.

2. Ifayibha yesafire ekhonkxiweyo: I-taper yonyusa ifayibha ekugqibeleni, iqinisekisa ukuphuma okuphezulu ngaphandle kokulahlekelwa bukuguquguquka kwayo ekudlulisweni kwamandla kunye nokusetyenziswa kwe-spectral.

Iindawo eziphambili zesicelo

1. Ishishini lenyukliya: Ngenxa yoxinano lwayo oluphezulu kunye nokumelana nokugqwala, iityhubhu zeseramikhi zesilicon carbide zisetyenziswa kakhulu kwiipayipi zokupholisa kunye neendibano zamafutha kwiireactor zenyukliya.
2.Indawo yomoya: Iityhubhu ze-silicon carbide ceramic zisetyenziswa ekwenziweni kwezinto ze-injini yeenqwelo-moya kunye nezinto ze-spacecraft ngenxa yokukhanya kwazo, amandla aphezulu kunye nokumelana nobushushu obuphezulu.
3. Izixhobo zobushushu obuphezulu: Kwii-ovens zobushushu obuphezulu, ii-sensors zobushushu obuphezulu kunye nee-reactors zobushushu obuphezulu, iityhubhu ze-silicon carbide ceramic zisetyenziswa kakhulu ngenxa yokumelana kwazo nobushushu obuphezulu kunye nokumelana ne-oxidation.
4. Izixhobo ze-elektroniki ezisebenzisa amandla: iityhubhu ze-ceramic ze-silicon carbide zingasetyenziselwa ukwenza izinto zokupakisha zezixhobo zamandla ukuphucula ukusebenza kakuhle kokusasaza ubushushu kunye nokuthembeka kwezixhobo.
5. Izithuthi zamandla amatsha: Kwizithuthi zamandla amatsha, iityhubhu ze-silicon carbide ceramic zingasetyenziselwa ukuvelisa izinto ezibalulekileyo kwinkqubo yolawulo lwebhetri ukuphucula uzinzo kunye nokhuseleko lwenkqubo.
I-XKH inikezela ngoluhlu olubanzi lweenkonzo ezenziwe ngokwezifiso zeetyhubhu ze-ceramic ze-silicon carbide, ukusuka ekukhetheni izinto kunye noyilo olunemilinganiselo ukuya ekulungisweni komphezulu, ukuqinisekisa ukuba iimveliso ziyahlangabezana neemfuno ezithile zabathengi.
1. Ngokuphathelele izinto, izinto ezikrwada ze-silicon carbide zobumsulwa obahlukeneyo kunye nobukhulu beesuntswana zinokukhethwa ngokweemfuno zabathengi ukuze kuhlangatyezwane neemeko ezahlukeneyo zesicelo ezifana nobushushu obuphezulu, ukumelana nokugqwala okanye amandla aphezulu.
