Silicon carbide ceramic kare beam roller inkoni: 'umurwanyi utuje' kurugamba rwo hejuru

Mu nganda zerekana itanura rya toni hamwe n’itanura ry’imiyoboro, ibidukikije byo hejuru ni nk '“umusozi ugurumana” - ibikoresho bikenera kwihanganira gutwika igihe kirekire hejuru ya 800 ℃, mu gihe kandi birwanya isuri ya gaze ya okiside ndetse na gaze ya aside. Ibikoresho gakondo byicyuma bikunda koroshya no guhindura ibintu muri ibi bidukikije, bigatuma kugabanuka gutunguranye kuramba. Ariko,inkingi ya kare ya kare ikozwe muri silicon karbide (SiC)ibikoresho ni nk '"umurwanyi wo mu rwego rwo hejuru", wishingikirije kuri gene irwanya ubushyuhe, uhinduka "inyanja yo mu nyanja" kugirango ikore neza itanura ry'ubushyuhe bwo hejuru.
Impamvu ituma silicon karbide kare ya beam beam ishobora guhinduka "ace player" mumurima wubushyuhe bwo hejuru biterwa nibintu byihariye bidasanzwe:
1. Wiyubake wenyine "barrière yumuriro"
Iyo ubushyuhe burenze 1200 ℃, firime ya dioxyde ya silicon yuzuye (SiO ₂) izahita ikora hejuru ya karubide ya silicon. Uru rwego rw "intwaro zibonerana" ntirushobora gutandukanya gusa ingaruka ziterwa nubushyuhe bwo hejuru kuri substrate, ariko kandi runarwanya kwinjiza imyuka ya acide, bigera ku "kurinda ibintu bibiri kwirinda ubushyuhe bukabije".

2. Iyo ishyushye, niko ikomera
Bitandukanye n'ibiranga ibikoresho by'icyuma byoroha iyo bihuye n'ubushyuhe, karbide ya silikoni ntigumana gusa imbaraga zayo zigoramye mu bushyuhe bwo hejuru bwa 800 ℃ -1350 but, ariko inerekana ko hari iterambere. Ibi "bihabanye nicyerekezo" biranga umubiri bituma uruziga ruguma rukomeye mubushyuhe bwo hejuru, birinda gusenyuka kwimiterere biterwa no koroshya.
3. Ubushyuhe bwa “teleportation master”
Amashanyarazi ya karubide ya silicon yikubye inshuro enye icyuma, gishobora gukwirakwiza vuba kandi kuringaniza ubushyuhe bwaho nka "umuhanda wubushyuhe", ukirinda kwirundanya "ahantu hashyushye" mu itanura. Ibi biranga ntabwo birinda uruziga ubwarwo gusa, ahubwo binagumana ituze ryubushyuhe bwa reaction ya desulfurizasi, bizamura imikorere muri rusange.
Yavukiye mu nganda zo hejuru-ubushyuhe
Ubushyuhe bwo hejuru burwanya silikoni karbide kwaduka ya beam ituma iba indashyikirwa cyane mubihe byo hejuru yubushyuhe bwo hejuru nko gutekesha amashanyarazi, gucana ibyuma, no kumena imiti. Nyuma yo kwemeza iki gice, ibigo birashobora kugabanya cyane inshuro zo guhagarika ubushyuhe bwo hejuru no kubungabunga, mugihe byongereye igihe cyumurimo wibikoresho inshuro nyinshi nkibikoresho gakondo, bikagera rwose "ubushyuhe bwo hejuru nta guhagarika, kurengera ibidukikije bidakonje".
Nkumushinga udasanzwe winzobere mubushakashatsi no guteza imbere ibikoresho bya ceramic silicon carbide, tuzi neza ububabare bwibikoresho mugihe gikora cyane. Buri silicon karbide kare ya beam roller ikubiyemo ubushakashatsi bwimbitse bwibikoresho siyanse. Mu bihe biri imbere, tuzakomeza kwibanda ku “kurwanya ubushyuhe bwo hejuru” nk'icyerekezo cy'ibanze, kandi dukoreshe imbaraga z'ikoranabuhanga mu kurinda umurongo w'icyatsi kibisi ukomoka ku nganda.
