I-Boron Nitride (BN) iiCeramics ezenziwe ngu-WINTRUSTEK

Iiseramikhi ze-Boron Nitride (BN) zezinye zeseraramikhi zodidi lobugcisa. Badibanisa iipropathi ezikhethekileyo zokumelana nobushushu, ezifana ne-thermal conductivities ephezulu, kunye namandla aphezulu e-dielectric kunye ne-inertness ekhethekileyo yeekhemikhali ukusombulula iingxaki kwezinye iindawo ezifuna kakhulu izicelo zehlabathi.

I-Boron Nitride ceramics yenziwa ngokucinezelwa kumaqondo obushushu aphezulu. Le ndlela isebenzisa amaqondo obushushu ukuya kutsho kuma-2000°C kunye noxinzelelo oluphakathi ukuya kolukhulu ukuphembelela ukuntywila komgubo okrwada we-BN kwibhloko enkulu, exineneyo eyaziwa ngokuba yibillet. Ezi bhiliti ze-Boron Nitride zinokwenziwa ngokulula kwaye zigqitywe zibe zizinto ezigudileyo, ezintsonkothileyo zejiyometri. Ukuchaneka okulula ngaphandle kokuphazamiseka kokudubula okuluhlaza, ukugawula, kunye nokukhenkceza kuvumela umboniso okhawulezayo, uhlengahlengiso loyilo, kunye nemijikelo yesiqinisekiso kwiinkqubo ezahlukeneyo zobunjineli ezikwinqanaba eliphezulu.

Ubunjineli begumbi lePlasma lolunye olunjalo lokusetyenziswa kwe-Boron Nitride ceramics. Ukuxhathisa kwe-BN kwi-sputtering kunye nokuthambekela okuphantsi kokuveliswa kwe-ion yesibini, naphambi kobukho bemimandla eqinile ye-electromagnetic, iyahlula kwezinye iiseramics eziphambili kwiindawo zeplasma. Ukumelana ne-sputtering kunegalelo ekomeleleni kwamacandelo, ngelixa i-ion ephantsi yokuvelisa i-ion inceda ukugcina ingqibelelo yendawo yeplasma. Isetyenziswe njenge-insulator ephezulu kwiinkqubo ezahlukeneyo zokugquma ifilimu, kubandakanywa i-plasma-enhanced physical vapor deposition (PVD).

Ukufakwa komphunga womzimba ligama loluhlu olubanzi lweendlela zokugquma ezibhityileyo ezenziwe kwi-vacuum kwaye zisetyenziselwa ukutshintsha umphezulu wezinto ezahlukeneyo. Abantu bahlala besebenzisa i-sputtering deposition kunye ne-PVD yokwambathisa ukwenza kunye nokubeka izinto ekujoliswe kuzo kumphezulu we-substrate xa besenza izixhobo ze-optoelectronic, iimoto ezichanekileyo kunye neendawo ze-aerospace, kunye nezinye izinto. I-Sputtering yinkqubo ekhethekileyo apho i-plasma isetyenziselwa ukugcina ukubetha into ekujoliswe kuyo kunye nokunyanzela amasuntswana kuyo. I-Boron Nitride ceramics idla ngokusetyenziswa ukuvalela ii-plasma arcs kumagumbi okufafaza kwizinto ekujoliswe kuzo nokuthintela ukhukuliseko lwamalungu adityanisiweyo egumbi.

I-Boron Nitride ceramics nayo isetyenziselwe ukwenza ii-sathelayithi ze-Hall-effect thrusters zisebenze ngcono kwaye zihlale ixesha elide.

Iimpembelelo zeholo zeholo zihambisa iisathelayithi kwi-orbit kunye ne-probes kwindawo enzulu ngoncedo lwe-plasma. Le plasma yenziwa xa umjelo we-ceramic osebenza kakhulu usetyenziselwa ukwenza i-ionize igesi ye-propellant njengoko ihamba kwindawo eqinile yemagnethi. Intsimi yombane isetyenziselwa ukukhawulezisa i-plasma kwaye iyihambise ngomjelo wokukhupha. Isiyilelo-gazi sinokulishiya ijelo ngesantya kumashumi amawaka eekhilomitha ngeyure. Ukhukuliseko lwePlasma luthanda ukophula amajelo okukhutshwa kwe-ceramic ngokukhawuleza, okuyingxaki kobu buchwepheshe buphambili. I-Boron Nitride ceramics isetyenziswe ngempumelelo ukunyusa ubomi beholo-yesiphumo se-plasma thrusters ngaphandle kokuphazamisa ukusebenza kakuhle kwe-ionization okanye amandla okuqhubela phambili.
