I-Tungsten yintsimbi enqabileyo, ekhangeleka njengentsimbi. Ibe yenye yezona zinto zibalulekileyo ezisebenzayo kwishishini lanamhlanje, ukhuselo lwelizwe kunye nezicelo zobuchwephesha obuphezulu ngenxa yendawo ephezulu yokunyibilika, ubunzima obuphezulu, ukuchasana nokugqwala okugqwesileyo kunye nokuhamba kakuhle kombane kunye ne-thermal. Ziziphi iindawo ezikhethekileyo zokusetyenziswa kwe-tungsten?
1. Intsimi yengxubevange
intsimbi
Ngenxa yobunzima bayo obuphezulu kunye noxinzelelo oluphezulu, i-tungsten yinto ebalulekileyo ye-alloy kuba inokuphucula kakhulu amandla, ukuqina kunye nokumelana nokunxiba kwentsimbi. Isetyenziswa ngokubanzi kwimveliso yeentsimbi ezahlukeneyo. I-tungsten eqhelekileyo equlethe iintsimbi ziquka isinyithi esinesantya esiphezulu, intsimbi ye-tungsten kunye nentsimbi ye-tungsten cobalt magnetic. Zisetyenziswa ikakhulu ukwenza izixhobo ezahlukeneyo, ezinje ngamasuntswana e-drill, abasiki bemilling, ukubumba ababhinqileyo kunye nokubumba kwamadoda.
I-tungsten isekelwe kwi-carbide enesamente
I-Tungsten carbide inokumelana nokunxiba okuphezulu kunye ne-refractory, kwaye ubunzima bayo busondele kwidayimane, ngoko ke isetyenziswa rhoqo kwimveliso ye-carbide enesamente. I-tungsten i-carbide esekwe kwi-cemented carbide ingahlulwa ngokubanzi ibe ngamacandelo amane: i-tungsten carbide cobalt, i-tungsten carbide titanium carbide cobalt, i-tungsten carbide titanium carbide tantalum (niobium) - i-cobalt kunye nentsimbi eboshwe nge-cemented carbide. Zisetyenziswa ikakhulu ukwenza izixhobo zokusika, izixhobo zemigodi kunye nokuzoba ngocingo kuyafa.

Nxiba i-alloy enganyangekiyo
I-Tungsten sisinyithi esiphikisayo esineyona ndawo iphakamileyo yokunyibilika (iphezulu kune-1650 ℃), enobunzima obuphezulu, ngoko ke ihlala isetyenziselwa ukwenza amandla obushushu kunye ne-alloys ekwazi ukumelana nokunxiba, njengealloyi zetungsten kunye nechromium, icobalt kunye nekhabhoni. ezihlala zisetyenziselwa ukuvelisa iindawo ezikwaziyo ukunxiba njengevalve ye-aeroengine kunye ne-turbine impeller, i-alloys ye-tungsten kunye ezinye iintsimbi eziphikisayo (ezifana ne-tantalum, niobium, molybdenum kunye nerhenium) zihlala zisetyenziselwa ukuvelisa iindawo zamandla aphezulu ashushu afana nombhobho werokethi kunye nenjini.
I-alloy yobunzima obuphezulu
I-Tungsten iye yaba yinto efanelekileyo yokwenza iialloys zomxhuzulane ophakamileyo ngenxa yoxinaniso oluphezulu kunye nobunzima obuphezulu. Ngokweempawu ezahlukeneyo zokuqulunqa kunye nokusetyenziswa, ezi zixhobo eziphezulu zobunzima obuphezulu zinokuhlulwa zibe yi-W-Ni-Fe, i-W-Ni-Cu, i-W-Co, i-w-wc-cu, i-W-Ag kunye nolunye uchungechunge. Zihlala zisetyenziselwa ukuvelisa izixhobo zoqhagamshelwano ezifana nezixhobo zokulwa, iphepha lokulahla ubushushu, ukutshintshela imela, i-breaker circuit kunye nokunye ngenxa yobunzima obukhulu, amandla aphezulu, ukuhanjiswa kwe-thermal ephezulu, ukuhanjiswa kombane okulungileyo kunye nokusebenza okuphezulu.
2. Intsimi yombane
I-Tungsten isetyenziswa kakhulu kwishishini lombane kunye nakumashishini amandla ngenxa yeplastiki eyomeleleyo, isantya esisezantsi sokunyuka komphunga, indawo ephezulu yokunyibilika kunye nokukwazi ukukhupha i-electron eyomeleleyo. Umzekelo, i-tungsten filament inezinga eliphezulu elikhanyayo kunye nobomi benkonzo ende, kwaye isoloko isetyenziselwa ukwenza imicu yebhalbhu eyahlukeneyo, njengesibane se-incandescent, isibane se-iodine tungsten njalo njalo. Ukongeza, ucingo lwe-tungsten lunokusetyenziswa ukwenza i-cathode eshushu ethe ngqo kunye negridi yetyhubhu ye-oscillation ye-elektroniki kunye ne-cathode heater kwizixhobo ezahlukeneyo ze-elektroniki.
3, ishishini Chemical
Iikhompawundi zeTungsten ziqhele ukusetyenziselwa ukuvelisa iintlobo ezithile zepeyinti, iipigments, ii-inki, izinto zokuthambisa kunye neecatalysts. Ngokomzekelo, i-sodium tungstate isetyenziswa ngokuqhelekileyo ekwenzeni i-metal tungsten, i-tungstic acid kunye ne-tungstate, kunye nedayi, i-pigments, i-inki, i-electroplating, njl. I-asidi ye-tungstic isoloko isetyenziswa njenge-mordant kunye nedayi kwishishini le-textile kunye ne-catalyst yokulungiselela i-octane ephezulu yepetroli kwishishini lemichiza; I-Tungsten disulfide isoloko isetyenziswa kwi-organic synthesis, njenge-lubricant eqinileyo kunye ne-catalyst ekulungiseleleni i-petroli yokwenziwa; I-bronze tungsten oxide isetyenziselwa ukupeyinta.

4, Intsimi yezonyango
Ngenxa yokuqina kwayo okuphezulu kunye nokuxinana, i-tungsten alloy ifaneleke kakhulu kwiinkalo zonyango ezifana ne-X-ray kunye nokukhusela i-radiation. Iimveliso zonyango ze-tungsten eziqhelekileyo zibandakanya i-anode ye-X-reyi, i-anti scattering plate, isikhongozeli se-radioactive kunye ne-syringe yokukhusela isikhongozeli.
5. Ibala lomkhosi
Ngenxa yeempawu zayo ezingeyotyhefu kunye nezobume bendawo, iimveliso zetungsten zisetyenzisiwe ukuthathela indawo ilothe yangaphambili kunye nezixhobo eziphelelweyo zeuranium ukwenza iimbumbulu zemfazwe, ukuze kuncitshiswe ungcoliseko lwezixhobo zomkhosi kwimo engqongileyo. Ukongeza, ngenxa yeempawu zobunzima obuqinileyo kunye nokuchasana okuhle kobushushu obuphezulu, i-tungsten inokwenza ukuba ukusebenza kokulwa kweemveliso zomkhosi ezilungiselelwe ziphakame ngakumbi. Iimveliso zeTungsten ezisetyenziswa emkhosini ikakhulu ziquka iimbumbulu ze-tungsten alloy kunye neembumbulu zokugqobhoza zesikrweqe zamandla ekinetic.
Ukongeza kule mimandla ingentla, i-tungsten ingasetyenziselwa kwi-aerospace, ukuhamba, amandla e-athomu, ukwakhiwa kweenqanawa, imboni yemoto kunye nezinye iindawo.
