I-Boron Nitride (BN) Ceramics Eyenziwe Ngu-WINTRUSTEK

Izitsha zobumba ze-Boron Nitride (BN) ziphakathi kwezitsha zobumba ezisebenza kahle kakhulu zebanga lobuchwepheshe. Ahlanganisa izici ezihlukile ezimelana nezinga lokushisa, njengama-thermal conductivity aphezulu, namandla aphezulu e-dielectric kanye nokungangeni kwamakhemikhali okukhethekile ukuze kuxazululwe izinkinga kwezinye zezindawo zokufaka izicelo ezidinga kakhulu emhlabeni.

I-Boron Nitride ceramics ikhiqizwa ngokucindezela emazingeni okushisa aphezulu. Le ndlela isebenzisa amazinga okushisa afinyelela ku-2000°C kanye nezingcindezi ezimaphakathi ukuya kwezinkulu ukuze kufakwe ukucwiliswa kwezimpushana ze-BN ezingaphekiwe zibe yibhulokhi enkulu, ehlangene eyaziwa ngokuthi i-billet. Lezi zinhlamvu ze-Boron Nitride zingenziwa kalula ngomshini futhi ziqedelwe zibe izingxenye ezibushelelezi, eziyinkimbinkimbi zejiyomethri. Ukusebenziseka kalula ngaphandle kokuhlupheka kokudubula okuluhlaza, ukugaya, kanye nokucwebezela kuvumela ukwenziwa kwe-prototyping ngokushesha, ukuguqulwa kwedizayini, nemijikelezo yokufaneleka kuzinhlelo zokusebenza ezithuthukisiwe zobunjiniyela.

Ubunjiniyela begumbi le-Plasma okunye ukusetshenziswa okunjalo kwe-Boron Nitride ceramics. Ukumelana kwe-BN nokuchaphaza kanye nokuthambekela okuphansi kokukhiqizwa kwe-ion yesibili, ngisho nalapho kunezinkambu eziqinile zikazibuthe, ihlukanise kwezinye izitsha zobumba ezithuthukisiwe ezindaweni ze-plasma. Ukumelana ne-sputtering kunomthelela ekuqina kwezingxenye, kuyilapho ukukhiqizwa kwe-ion yesibili ephansi kusiza ukulondoloza ubuqotho bemvelo ye-plasma. Isetshenziswe njengesivikeli esithuthukisiwe ezinqubweni ezihlukahlukene zokumboza amafilimu amancane, okuhlanganisa i-plasma-enhanced physical vapor deposition (PVD).

I-Physical vapor deposition yitemu lezinhlobonhlobo zezindlela zokumboza zefilimu ezincanyana ezenziwa ku-vacuum futhi zisetshenziselwa ukushintsha ubuso bezinto ezahlukene. Abantu bavame ukusebenzisa i-sputtering deposition kanye ne-PVD coating ukuze benze futhi babeke izinto eziqondiwe phezu kwe-substrate lapho benza amadivaysi e-optoelectronic, izingxenye ezinembile zezimoto neze-aerospace, nezinye izinto. I-Sputtering iyinqubo eyingqayizivele lapho i-plasma isetshenziselwa ukuqhubeka nokushaya into ehlosiwe futhi ikhiphe izinhlayiya kuyo. I-Boron Nitride ceramics ivamise ukusetshenziselwa ukuvala ama-arc e-plasma emagumbini okufafaza ezintweni eziqondiwe kanye nokuvikela ukuguguleka kwezingxenye ezibalulekile zegumbi.

I-Boron Nitride ceramics nayo isetshenziselwe ukwenza ama-thruster e-Hall-effect asathelayithi asebenze kangcono futhi ahlale isikhathi eside.

Ama-thruster omphumela wehholo ahambisa amasathelayithi ku-orbit futhi aphenya endaweni ejulile ngosizo lwe-plasma. Le plasma yenziwa lapho umzila we-ceramic osebenza kahle kakhulu usetshenziselwa ukwenza i-ionize igesi ephumayo njengoba ihamba endaweni eqinile kazibuthe. Inkambu kagesi isetshenziselwa ukusheshisa i-plasma nokuyihambisa ngokusebenzisa umgudu wokukhipha. I-plasma ingashiya isiteshi ngesivinini emashumini ezinkulungwane zamamayela ngehora. Ukuguguleka kwe-Plasma kuvame ukudiliza iziteshi zokukhishwa kwe-ceramic ngokushesha okukhulu, okuyinkinga kulobu buchwepheshe obuphambili. I-Boron Nitride ceramics isetshenziswe ngempumelelo ukuze kwandiswe isikhathi sokuphila se-holo-effect plasma thrusters ngaphandle kokuphazamisa ukusebenza kahle kwe-ionization noma amandla okuqhubela phambili.
