Tungsten waya: Inoshandiswa kugadzira tungsten-rhodium thermocouples uye inokurumidza-yakabatana misoro, waya dzakasungwa nesafire, uye maelectrodes emalaser makuru. Inoshandiswawo kugadzira filaments yepamusoro uye chubhu cathodes. Muna 2005, iyo yakawanda-chinangwa tungsten-rhenium alloy waya yakagadziriswa nekambani yedu yakanyorwa sechinhu chakakosha chenyika chigadzirwa neBazi reSainzi neTekinoroji.
Tungsten-rhenium thermocouple waya ine nzvimbo yekunyungudika ye3120-3360 °C uye inogona kushandiswa kusvika 3000 °C. Ndiyo inonyanya kupikisa metal thermocouple. Iyo ine zvakanakira hukama hwakanaka hwemutsara pakati petembiricha uye electromotive simba, yakavimbika thermal kugadzikana uye yakaderera mutengo. Inofananidzwa nechiridzwa chekuratidzira. Tembiricha inogona kuyerwa zvakananga parizvino inoyerwa patembiricha iri pamusoro pe1600 ° C. Iyo isiri-contact nzira inowanzoshandiswa. Zvisinei, kukanganisa kwenzira iyi kwakakura. Semuenzaniso, tembiricha yekusangana inogona kunyatso kuyera tembiricha yechokwadi. Mupamusoro-tembiricha thermocouples, simbi yakakosha thermocouples (platinum-rhodium thermocouples) inodhura uye tembiricha yepamusoro inogona kungova pasi pe1800 ° C, nepo tungsten-rhodium thermocouples isingaite tembiricha yepamusoro chete asiwo kugadzikana kwakanaka, saka, tungsten- rhodium thermocouples Inoshandiswa zvakanyanya musimbi, zvivakwa zvekuvaka, aerospace, ndege uye maindasitiri esimba renyukireya. Iyo yakanyanya tembiricha yekushanda inogona kusvika 2800 ° C, asi pane inopfuura 2300 ° C, iyo data inoparadzirwa. Tungsten-rhenium thermocouples zvakare ine oxidizable yakanyanya, saka inogona kushandiswa muvacuum, kudzikisira, kana inert mhepo patembiricha kubva pa0 kusvika 2300 ° C. Tungsten bismuth vakaroorana vane machubhu anokosha ekudzivirira anogonawo kushandiswa kwenguva yakareba mumhepo ine oxidizing pa 1600 ° C. Izvo zvakachipa kupfuura platinum-rhodium thermocouples uye haigoni kushandiswa mumhepo ine carbon-containing atmospheres (semu hydrocarbon-containing atmospheres, tembiricha inodarika 1200 ° C iri pasi pekuora). Tungsten kana tungsten ruthenium inowanzoita yakagadzikana carbides mumhepo ine kabhoni, kuitira kuti kunzwisiswa kwayo kuderedzwa uye brittle fracture inokonzerwa, uye pamberi pehydrogen, carbonization inokurumidza. Iyo kambani inoshanda mukugadzira anti-oxidation tungsten-rhodium thermocouples. Iyo yakanaka tembiricha yemhando ndeye 0-1500 °C. Iyo dhizaini yakapetwa kaviri-layer kana matatu-layer (isingawanzo kushandiswa) yekudzivirira chubhu. Iyo yekunze yekudzivirira chubhu yekaviri yekudzivirira chubhu chimiro ndeye Ultra-pure corundum chubhu. Iyo yemukati yekudzivirira chubhu ndeye molybdenum silicide chubhu, uye iyo yekunze yekudzivirira chubhu yeatatu sleeve ndeye recrystallized silicon carbide chubhu kana yakakosha pure corundum chubhu, iyo yepakati chubhu uye yemukati yekudzivirira chubhu zvakafanana nembiri chubhu mhando, uye iyo chubhu yekuzadza zvinhu ndeye yakakwira tembiricha insulating zvinhu (inogona kunge iri Yenguva refu yekushandiswa pazasi 1800 ° C), vacuum chisimbiso uye kutonhora-kuguma kuvharira (kunamira chisimbiso kunogona kushandiswa pakupisa kuri pasi pe300 ° C kwenguva yakareba) kuve nechokwadi kwete. okisijeni yakasara muchubhu. Ichi chigadzirwa chakakodzera kushandiswa muvacuum, kuderedza uye mamwe magasi anert (0 ~ 1650 °C) Yakanaka tembiricha kuyerwa mumhepo oxidizing ndeye 0 kusvika 1500 °C. Nguva isingachinji: ≥180 s
