{{0 {}} Vim li cas thiaj titanium yog kim?
Tsis tshua muaj thiab nyuaj rau kuv li:
Titanium muaj ntau nyob rau hauv lub ntiaj teb crust (e {{{}}}. {1} {{1} .
Zog-kev rho tawm:
Cov txheej txheem KROLRY, thawj txoj kev los tsim cov khoom siv titanium, koom nrog cov magnesium
Nyuaj manufacturing:
Titanium muaj lub siab melting taw tes (1,668 degree), ua kev tso duab, thiab machining}}}} .
Qes Ntau Lawm Nplai:
Piv rau cov hlau los yog txhuas, titanium ntau lawm (kev tawm hauv ntiaj teb txhua xyoo
2. tuaj yeem titanium xeb?
Ntuj corrosion resistance:
Titanium ua ib qho nyias nyias, nws tus kheej kho oxide txheej (tunanium tiv thaiv xeb, dej qab zib, thiab feem ntau {2} {2} {2} {2}
Txwv:
Nyob rau hauv cov xwm txheej acidic siab (e {{{{0} g {}} txheej tuaj yeem tawg, ua rau corrosion .
Prolonged raug rau chloride rau chloride ions (e {{{} g}}
Piv rau Hlau:
Tsis zoo li cov hlau stainless, titanium lub corrosion tsis kam yog qhov xam, tsis yog nyob ntawm alloy .
{{0 {}} Dab tsi ua kev puas tsuaj titanium?
Neeg kho tshuab ntxhov siab tshaj qhov txwv:
Thaum muaj zog, titanium muaj qis dua me ntsis dua li qee cov hlau, ua rau nws raug kev tawg ua kom tawg (nkees) lossis cuam tshuam}
Kev kub-taws teeb meem:
Ntawm qhov kub tshaj 400-500 degree, thiab nws yuav hnov mob nrog oxygen, lossis hydrogen, los yog hydranium hluav taws "hauv cov neeg mob titanium"}}
Tshuaj lom neeg tawm tsam hauv ib puag ncig:
Cov kua qaub muaj zog acids (e {{{0} g}}}}}}}}}}}}
Raug rau hydrogen gas ntawm qhov kub muaj peev xwm ua rau "hydrogen embrittlement," ua rau cov hlau caiv nti .
Puas Txhob thiab Hnav:
Titanium muaj qhov hnyav dua li qee cov hlau, yog li nws yuav kos lossis hnav hauv kev sib txhuam (e ., uncoated cuab yeej).
{{0 {}} tuaj yeem tsim tau weldanium yuav welded?
Vuam Txoj Kev:
Tungsten inert gas (tsov) vuam: feem ntau, siv helium los tiv thaiv cov pa roj oxygen thiab nitrogen, uas ua rau brittleness.
Ntshav vuam thiab hluav taws xob nqaj vuam: siv rau cov tuab tuab lossis qhov ntsuas qhov tseeb {{}
Cov nyom:
Tsis huv los ntawm huab cua (o₂, n₂) thaum lub sij hawm vuam tuaj yeem ua rau cov khoom siv hlau, yog li chav weld thiab cov khoom siv rau nruj me nyuam .
Tom qab kev kho cua sov yuav siv tau los daws kev ntxhov siab thiab tswj hwm ductility .
Qhov tseem ceeb:
Welders yuav tsum tau raug cob qhia hauv titanium-tshwj xeeb cov tswv yim kev paub kom tsis txhob muaj hlau sib kis (e}}} {.
{{0 {}} Yuav qhia li cas yog tias nws yog tiag Titanium?
Lub cev yuag:
Titanium yog lub teeb nrig (ceev dua ~ 4 {{}}}}}}}}}} 8 g / 2.7 g / cm³). Lub titanium khoom yuav hnov "ntom tab sis lub teeb" piv rau cov hlau.
Hlau nplaum Xeem:
Cov tawv nqaij ntshiab thiab feem ntau cov alloys tsis muaj hlau nplaum.} Yog tias muaj cov hlau nplaum me me yog tias txias dua yog tias txias txias) .
Ntsuas Kev Ntsuas:
Tawm tsam cov hlau tawm tsam ib grinder: titanium ua ci, thaum cov hlau tawg, xim steel .
Corrosion xeem:
Thov kev poob ntawm cov tshuaj ntxuav tes hauv tsev (uas muaj chloride) thiab tos: titanium resards corrosion, thaum hlau yuav discolor lossis xeb .
Kos test:
Titanium muaj kev nyuaj (30-40 hrc). nws tuaj yeem tawm ib qho cim (txawm tias qhov kev puas tsuaj no ({}
Txuj ci tshaj lij:
X-Tshav Ntuj Fluorescence (XRF): Ntsuam xyuas cov hlau lub theem pib muaj pes tsawg .
Kev kuaj kub: Titanium melts ntawm ~ 1,668 degree; cov ntsiab lus qis melting qhia txog lwm yam hlau (e . me} suab paj nruag ntawm ~ 660 degree) {5} {5}
Titanium qhov kev siv tshwm sim los ntawm nws cov kev ua haujlwm nyuaj, siv qhov hnyav, thiab kev ua haujlwm zoo, pab ua kom puas tsuaj-kev siv hauv ntau yam Kev Siv .
