Ukusetyenziswa kwesinyithi esichasayo

Iimethali eziRefractory luhlobo lwemathiriyeli yentsimbi enokumelana nobushushu kunye nendawo ephezulu yokunyibilika.

Ezi zinto eziphikisayo, kunye neentlobo ezahlukeneyo ze-compounds kunye ne-alloys eziqulunqwe kuzo, zineempawu ezininzi eziqhelekileyo. Ukongeza kwindawo ephezulu yokunyibilika, bakwanayo nokumelana ne-corrosion ephezulu, ukuxinana okuphezulu, kunye nokugcina amandla omatshini aphezulu kumaqondo obushushu aphezulu. Ezi mpawu zithetha ukuba isinyithi esichasayo sinokusetyenziswa kwiindawo ezininzi, ezifana ne-glass melting electrode, iinxalenye zesithando somlilo, iithagethi ze-sputtering, ii-radiator kunye nee-crucibles. Iingcali zeSebe leTekhnoloji ye-RSM zazisa iintsimbi ezimbini ezixhaphakileyo ezisetyenziswa ngokuqhelekileyo kunye nezicelo zazo, ezizezi, i-molybdenum kunye ne-niobium.

molybdenum

Yeyona nto isetyenziswa kakhulu kwintsimbi ye-refractory kwaye ineempawu ezibalaseleyo zoomatshini phantsi kobushushu obuphezulu, ukwandiswa kwe-thermal ephantsi kunye ne-thermal conductivity ephezulu.

Ezi zakhiwo zithetha ukuba i-molybdenum inokusetyenziselwa ukwenza iindawo ezomeleleyo zezicelo zobushushu obuphezulu, ezinje ngeendawo ezithweleyo, iipakethi ze-elevator brake, iindawo eziko, kunye ne-forging dies. I-Molybdenum isetyenziswa kwiiradiyetha ngenxa yokuhanjiswa kwayo okuphezulu kwe-thermal (138 W / (m · K)).

Ukongeza kwiimpawu zayo zomatshini kunye ne-thermal, i-molybdenum (2 × 107S / m), eyenza i-molybdenum isetyenziswe ukwenza i-electrode yokunyibilika kweglasi.

I-Molybdenum idla ngokuxutywa ngeentsimbi ezahlukeneyo kwizicelo ezifuna amandla obushushu, kuba i-molybdenum isenamandla aphezulu nakubushushu obuphezulu. I-TZM yi-alloy edumileyo yesiseko se-molybdenum, equlethe i-0.08% ye-zirconium kunye ne-0.5% ye-titanium. Amandla ale alloy kwi-1100 ° C malunga nokuphindwe kabini kwe-molybdenum engaxutywanga, kunye nokwandiswa okuphantsi kwe-thermal kunye nokuhanjiswa okuphezulu kwe-thermal.

niobium

I-Niobium, isinyithi esichasayo, ine-ductility ephezulu. I-Niobium ine-processability ephezulu nakwiqondo lokushisa eliphantsi, kwaye ineendlela ezininzi, ezifana ne-foil, ipleyiti kunye neshiti.

Njengesinyithi esichasayo, i-niobium inoxinano oluphantsi, okuthetha ukuba i-niobium alloys ingasetyenziselwa ukuvelisa amacandelo asebenza kakhulu aphikisayo anobunzima obulula. Ke ngoko, iialloys ze-niobium ezifana ne-C-103 zihlala zisetyenziswa kwii-injini ze-rocket ze-aerospace.

I-C-103 inamandla aphezulu okushisa aphezulu kwaye inokumelana namaqondo okushisa ukuya kwi-1482 ° C. Kwakhona i-formable kakhulu, apho inkqubo ye-TIG (i-Tungsten Inert Gas) ingasetyenziselwa ukuyidibanisa ngaphandle kokuchaphazela kakhulu ubugcisa okanye i-ductility.

Ukongeza, xa kuthelekiswa neentsimbi ezahlukeneyo refractory, ine thermal neutron cross cross section, ebonisa amandla kwisizukulwana esilandelayo sezicelo zenyukliya.
