Li-tubes tsa Tšireletso ea Thermocouple tsa Silicon Nitride tse Kopantsoeng le Silicon Carbide: Likopo le Bokhoni ba Custom

Lits'ebetsong tsa indasteri tse nang le mocheso o phahameng, tekanyo e nepahetseng le e tšepahalang ea mocheso ke motheo oa taolo ea boleng ba sehlahisoa, polokeho ea ts'ebetso le ts'ebeliso e ntle ea matla.Li-tubes tsa tšireletso ea thermocouple tse kopantsoeng le silicon carbide (NB SiC) tse nang le nitrideE hlahella e le tharollo e ntle ka ho fetisisa, e sebelisa melemo ea tšebelisano ea silicon nitride le silicon carbide ho ipabola maemong a thata ka ho fetisisa. Ntle le ts'ebetso ea bona e ikhethang, bokhoni ba rona ba ho iketsetsa lintho bo etselitsoeng uena bo netefatsa hore bo kopana hantle le li-setup tse fapaneng tsa indasteri, e leng se etsang hore e be khetho e ratoang bakeng sa bahlahisi ba lefats'e.

Ts'ebeliso ea lipeipi tsa tšireletso tsa thermocouple tsa NB SiC e akaretsa liindasteri tse ngata tse batloang haholo, tse susumetsoang ke thepa ea tsona e ikhethang—botsitso ba mocheso o phahameng ho fihlela ho 1500°C, khanyetso e ntle ea ho thothomela ha mocheso, le khanyetso e matla ea mafome. Ts'ebetsong ea tšepe e seng ea ferrous, li bohlokoa haholo bakeng sa ho lekanya mocheso liontong tsa aluminium, zinki, koporo le magnesium tse qhibilihang. Ho fapana le thepa ea setso, NB SiC ha e silafatse litšepe tse qhibilihisitsoeng, e netefatsa bohloeki ba lihlahisoa tsa ho qetela ha e ntse e boloka botsitso ba nako e telele. Bakeng sa indasteri ea tšepe le ea tšepe, lipeipi tsena li sebetsa ka mokhoa o tšepahalang liontong tsa ho phatloha le lits'ebetsong tsa ho phunya tse chesang, li mamella ho taboha ho tsoang lerōleng le lebelo le phahameng le scoria.
