Molweni, injongo imi ngolu hlobo lulandelayo
Ishishini leFilament
I-Tungsten yaqala ukusetyenziswa ukwenza imicu ye-incandescent.I-tungsten rhenium alloys ifundwe ngokubanzi.Itekhnoloji yokunyibilika kunye nokwenza i-tungsten nayo iyafundwa.I-tungsten ingots ifunyenwe nge-arc esetyenziswayo kunye ne-electron beam melting, kwaye ezinye iimveliso zenziwe nge-extrusion kunye ne-plastiki processing;Nangona kunjalo, i-ingot enyibilikayo ineenkozo ezinqabileyo, iplastiki ehluphekileyo, ukucubungula okunzima kunye nesivuno esincinci, ngoko ke inkqubo yokunyibilika kweplastiki ayizange ibe yindlela yokuvelisa imveliso.Ukongeza kwi-chemical vapor deposition (CVD) kunye nokutshiza ngeplasma, enokuvelisa iimveliso ezimbalwa kakhulu, i-metallurgy engumgubo iseyeyona ndlela iphambili yokwenza iimveliso ze-tungsten.
Ushishino lwamaphepha okusonga
Kwiminyaka yee-1960, uphando lwenziwa kwi-tungsten smelting, i-metallurgy yomgubo kunye neteknoloji yokucubungula.Ngoku inokuvelisa iipleyiti, amashiti, iifoyile, imivalo, imibhobho, iingcingo kunye nezinye iindawo ezineprofayili.
Ukusonga izixhobo zobushushu obuphezulu
Ubushushu bokusetyenziswa kwezinto ze-tungsten buphezulu, kwaye akusebenzi ukuphucula amandla obushushu obuphezulu be-tungsten ngokusebenzisa indlela yokomeleza isisombululo.Nangona kunjalo, ukusabalalisa (okanye imvula) ukomeleza ngesiseko sokuqinisa isisombululo kunokuphucula kakhulu amandla okushisa aphezulu, kwaye umphumo wokuqiniswa kwe-ThO2 kunye ne-precipitated HfC dispersion particles iyona nto ibhetele.Iialloyi ze-W-Hf-C kunye ne-W-ThO2 zinamandla aphezulu obushushu obuphezulu kunye namandla okurhubuluza malunga ne-1900 ℃.Yindlela esebenzayo yokuqinisa i-tungsten alloy esetyenziswe ngaphantsi kweqondo lokushisa lokubuyisela kwakhona ngokwamkela indlela yokusebenza efudumeleyo yokuqina ukuvelisa ukuqiniswa koxinzelelo.Ukuba ucingo lwe-tungsten olucolekileyo lunamandla aphezulu okuqina, ireyithi yokuguqulwa kwenkqubo iyonke
I-99.999% yocingo lwe-tungsten olucolekileyo olunobubanzi be-0.015 mm, amandla okuqina angama-438 kgf/mm kwiqondo lobushushu begumbi
Phakathi kweentsimbi eziphikisayo, i-tungsten kunye ne-tungsten alloys zinelona qondo lobushushu liphezulu leplastiki.Ubushushu beplastiki obuguquguqukayo benguqu ye-sintered kunye nenyibilikisiwe ye-polycrystalline tungsten imathiriyeli imalunga ne-150 ~ 450 ℃, ibangela ubunzima ekusetyenzweni nasekusetyenzisweni, ngelixa i-crystal tungsten enye isezantsi kunobushushu begumbi.Ukungcola kwangaphakathi, i-microstructures kunye ne-alloying elements kwizinto ze-tungsten, kunye nokusetyenzwa kweplastiki kunye nomgangatho ongaphezulu, kunempembelelo enkulu kubushushu beplastiki ye-brittle transition yezinto ze-tungsten.Ngaphandle kokuba i-rhenium inokunciphisa kakhulu i-plastic brittle transition ubushushu bezinto ze-tungsten, ezinye izinto ze-alloy zinefuthe elincinci ekunciphiseni i-plastic brittle transition lobushushu (jonga ukomeleza isinyithi).
I-Tungsten inokumelana ne-oxidation embi.Iimpawu zayo ze-oxidation zifana ne-molybdenum.I-Tungsten trioxide iyajika ibe ngaphaya kwe-1000 ℃, ikhokelela kwi-oxidation “eyintlekele”.Ngoko ke, izinto ze-tungsten kufuneka zikhuselwe nge-vacuum okanye i-inert atmosphere xa zisetyenziselwa ukushisa okuphezulu.Ukuba zisetyenziswe kwi-high-temperature oxidation atmosphere, iingubo ezikhuselayo kufuneka zongezwe.
Ishishini lezixhobo zomkhosi esongwayo
Ngophuhliso kunye nenkqubela phambili yenzululwazi, izixhobo ze-tungsten alloy ziye zaba yimathiriyeli ekrwada yokwenza iimveliso zasemkhosini namhlanje, ezinjengeembumbulu, izixhobo kunye namaqokobhe, iintloko zeembumbulu, iibhombu, imipu, iintloko zeembumbulu, izithuthi ezingangenwa ziimbumbulu, iitanki ezixhobileyo, inqwelomoya yomkhosi, iinqwelomoya. iinxalenye, imipu, njalo njalo. Iprojectile yokugqobhoza isikrweqe eyenziwe nge-alloy ye-tungsten ingagqobhoza isikrweqe kunye nesikrweqe esihlanganisiweyo esine-angle yokuthambekela enkulu, kwaye sesona sixhobo sichasene netanki.
I-tungsten alloys i-alloys esekelwe kwi-tungsten kwaye yenziwe ngezinye izinto.Phakathi kwesinyithi, i-tungsten ineyona ndawo iphezulu yokunyibilika, amandla obushushu obuphezulu, ukuxhathisa, ukuguquguquka kwe-thermal, ukuhanjiswa kombane kunye nokusebenza kwe-electron emission, ezibaluleke kakhulu, ngaphandle kwenani elikhulu lezicelo ekwenziweni kweekhabhidi ezinesamente kunye ne-alloy additives.
I-Tungsten kunye ne-alloys zayo zisetyenziswa ngokubanzi kumashishini ombane kunye nombane wokukhanya, kunye nakwi-aerospace, ukuphosa, izixhobo kunye namanye amacandelo okwenza imibhobho ye-rocket, i-mold-casting mold, i-armor cores bullet cores, abafowunelwa, izinto zokufudumeza kunye nobushushu. amakhaka.
