1.Koj tuaj yeem ua dab tsi?

Baoji Ruicheng Titanium Hlau Co., Ltd., nyob hauv High-tech Development Zone Baoji Shaanxi Tuam Tshoj uas yog nto moo li "Suav titanium nroog". Ruicheng yog lub tuam txhab thev naus laus zis tshwj xeeb nrog lub zog muaj zog, thev naus laus zis siab dua, cov khoom lag luam zoo thiab kev pabcuam zoo. Xyoo tsis ntev los no, Nyob ntawm cov khoom lag luam muaj txiaj ntsig ntawm "Suav lub nroog titanium," lub tuam txhab muaj zog tsis yog hlau hlau tshawb fawb thiab tsim khoom muaj zog, ntxiv rau ua kom tiav cov khoom lag luam titanium cov saw hlau. Ruicheng feem ntau yog tus saib xyuas kev tshawb fawb tob, Tsim thiab tsim khoom ntawm& civil titanium nrog rau lwm yam hlau tsis tshua muaj, thiab maj mam tsim cov txheej txheem ua tiav thiab ua tiav cov txheej txheem.

2.What cov khoom koj tuaj yeem muab tau?

A, Titanium anode B, titanium bar C, titanium ntawv (suav nrog Gr1 titanium ntawv ci) D, titanium ntsia hlau E, titanium raj F, Titanium hlau G, titanium txheej txheem ntu

Qhia me ntsis:

Titanium yog ib qho tseem ceeb txheej txheem hlau tsim nyob rau niaj hnub no. Titanium alloy tau siv dav hauv ntau qhov chaw vim tias nws muaj lub zog tshwj xeeb, tiv taus xeb thiab tiv tshav kub kub.Titanium, tsis muaj tshuaj lom, lub cev hnyav, lub zog siab thiab kev ua kom zoo sib xws, yog cov khoom siv hlau zoo tshaj plaws, nws cov cua sov tiv taus, lub zog, yas, tawv, tsim tau, weldability, tiv taus corrosion thiab biocompatibility yog qhov zoo, thiab dhau los ua ace alloy hauv kev lag luam. impurities, cov ntshiab titanium iodide cov ntsiab lus tsis huv tsis ntau tshaj 0.1%, tab sis nws lub zog qis, cov yas siab.Qhov khoom ntawm 99.5% cov khoom lag luam ntshiab titanium muaj raws li hauv qab no: ntom ρ=4.5g/cm3, melting point 172

Ntawm 5 ℃, thermal conductivity λ=15.24W/(mK), lub zog tensile σb=539MPa, elongation δ=25%, txo thaj tsam ψ=25%, elastic modulus E=1.078 × 105MPa, hardness HB195.

Lub zog siab:

Qhov ntom ntawm titanium alloy feem ntau yog kwv yees li 4.51g/cm3, tsuas yog 60% ntawm cov hlau, lub zog ntawm cov ntshiab titanium yog ze rau lub zog ntawm cov hlau zoo ib yam, qee qhov muaj zog titanium alloy ntau dua li lub zog ntawm ntau cov hlau sib xyaw ua ke.Yog li ntawd, lub zog tshwj xeeb (lub zog/ntom ntom) ntawm titanium alloy ntau dua li ntawm lwm cov khoom siv hlau, raws li qhia hauv Table 7-1. Nws tuaj yeem tsim cov khoom siv nrog lub zog siab, zoo nruj thiab lub cev nyhav. Tam sim no, titanium alloy tau siv rau lub cav ntu, pob txha, tawv nqaij, khawm nrawm thiab tsaws iav.

Siab thermal zog:

Kev siv qhov kub thiab txias yog ntau pua degrees siab dua aluminium alloy, ntawm qhov kub nruab nrab tseem tuaj yeem tswj lub zog xav tau, tuaj yeem ua haujlwm hauv 450 ~ 500 ℃ kub ntev ntev ob hom titanium alloy hauv thaj tsam ntawm 150 ℃ ~ 500 ℃ tseem muaj lub zog tshwj xeeb siab, thiab aluminium alloy ntawm 150 ℃ ntau dua li lub zog poob qis.Qhov kev ua haujlwm kub ntawm titanium alloy tuaj yeem ncav cuag 500 ℃, thiab tias aluminium alloy qis dua 200 ℃.

Zoo corrosion kuj:

Kev tiv thaiv corrosion ntawm titanium alloy yog qhov zoo dua li ntawm cov hlau tsis muaj hlau thaum ua haujlwm hauv huab cua ntub thiab nruab nrab dej hiav txwv.Resistance rau pitting xeb, kua qaub xeb, kev nyuaj siab corrosion yog tshwj xeeb yog muaj zog; Kev txhim kho corrosion zoo rau alkali, chloride, tshuaj chlorine cov khoom organic, nitric acid, sulfuric acid thiab ntxiv rau. Tab sis titanium muaj qhov tsis xeb tiv thaiv kom txo cov pa oxygen thiab chromite nruab nrab.

Kev ua haujlwm kub tsis zoo:

Titanium alloy tuaj yeem khaws nws cov khoom siv hluav taws xob ntawm qhov kub thiab txias qis heev.Titanium alloys nrog kev ntsuas kub zoo thiab qis qis qis qis, xws li TA7, tuaj yeem khaws qee yam yas ntawm -253 ℃. cov khoom siv ua kom sov.

Cov tshuaj lom neeg siab:

Titanium muaj cov tshuaj lom neeg siab, thiab muaj cov tshuaj muaj zog tiv taus nrog O, N, H, CO, CO2, dej ua pa thiab ammonia hauv huab cua. Thaum cov pa roj carbon ntau dua 0.2%, TiC nyuaj yuav tsim nyob rau hauv titanium alloy.t kub dua, TiN kuj tseem tsim los ntawm kev cuam tshuam nrog N

Cov txheej txheej tawv tawv; Tshaj siab tshaj 600 ℃, titanium nqus cov pa kom tsim cov txheej tawv nrog cov tawv tawv tawv. Thaum cov ntsiab lus hydrogen nce ntxiv, txheej txheej txheej yuav tau tsim. qib tawv tawv yog 20% ​​~ 30% .Titanium tshuaj lom neeg kuj tseem loj, yooj yim rau kev sib txhuam nto ua rau muaj qhov tshwm sim.

Kev ua kom muaj cua sov me me, kev hloov pauv me me:

Cov thermal conductivity ntawm titanium λ=15.24W/(mK) yog li 1/4 ntawm npib tsib xee, 1/5 ntawm cov hlau, 1/14 ntawm txhuas, thiab cov cua sov ua kom sov ntawm ntau yam titanium alloys yog li 50% qis dua li ntawm titanium .Qhov kev hloov pauv ntawm titanium alloy yog kwv yees li 1/2 ntawm cov hlau, yog li nws qhov kev ua haujlwm tsis zoo, hloov pauv tau yooj yim, yuav tsum tsis txhob ua tus pas nrig thiab cov phab ntsa nyias nyias, txiav qhov ua tiav ntawm lub caij nplooj ntoo hlav yog loj heev, kwv yees li 2 ~ 3 zaug ntawm cov hlau tsis muaj steel, ua rau muaj kev sib txhuam hnyav, ua kom nruj, ua rau hnav ntawm cov cuab yeej nto.

Siv:

Titanium hlau muaj siab zog thiab tsis tshua muaj ceev, zoo txhua yam khoom, zoo toughness thiab corrosion resistance.In tas li ntawd, titanium hlau txheej txheem kev kawm yog neeg pluag, tej nyuaj, nyob rau hauv kub ua, nws yog heev yooj yim mus nqus impurities xws li hydrogen, oxygen, nitrogen thiab carbon.There tsis zoo hnav tsis kam, txheej txheem txheej txheem tsim khoom lag luam titanium tau pib xyoo 1948. Kev xav tau ntawm kev txhim kho kev lag luam aviation ua rau titanium kev lag luam txhim kho ntawm qhov nruab nrab txhua xyoo kev loj hlob ntawm kwv yees li 8%. Tam sim no, txhua xyoo cov khoom siv titanium alloy ua cov khoom siv hauv ntiaj teb tau mus txog ntau dua 40,000 tons, ze li 30 yam ntawm titanium alloy.Qhov feem ntau siv titanium alloys yog Ti-6Al-4V (TC4), Ti-5Al-2.5Sn (TA7) thiab ntshiab titanium (TA1, TA2 thiab TA3).

Kev kho cua sov:

Feem ntau siv cov txheej txheem kev kho cua sov yog ua kom sov, kho thiab kho cov laus. Kev kho kom sov yog txhawm rau tshem tawm kev ntxhov siab sab hauv, txhim kho cov yas thiab microstructure ruaj khov, txhawm rau kom tau txais cov txiaj ntsig zoo dua qub.Generally, qhov kub ntawm qhov kub ntawm α hlau thiab (β β) alloy yog 120 ~ 200 ℃ qis dua qhov hloov pauv ntawm (β β) .The .The theem.Kev daws teeb meem thiab kev kho neeg laus yog kom tau txais α' theem thiab metastable β theem ntawm martensite los ntawm kev txias sai hauv cheeb tsam kub, thiab tom qab ntawd decompose cov theem metastable los ntawm kev tuav hauv thaj tsam kub nruab nrab, thiab tau txais cov nplua faib ua ntu ntu thib ob, xws li α theem lossis sib xyaw, kom ua tiav lub hom phiaj ntawm kev ntxiv dag zog rau hlau. ) ─ - beta theem hloov pauv taw tes qis dua 40 ~ 100 ℃, metastable beta alloy quenching hauv (alpha beta) ─ - beta theem hloov pauv taw tes saum toj no 40 ~ 80 ℃. Cov laus qhov kub yog feem ntau 450 ~ 550 ℃.

Hauv kev xaus, txheej txheem kho cua sov ntawm titanium alloy tuaj yeem sau ua ke raws li hauv qab no:

(1) Txhim kho kev nyuab siab: lub hom phiaj yog tshem tawm lossis txo qis qhov kev nyuab siab uas tau tsim hauv cov txheej txheem ua.

(2) Ua kom tiav qhov ua kom tiav: lub hom phiaj yog kom tau txais cov tawv tawv, txhim kho kev ua tiav, muaj txiaj ntsig rau kev rov ua dua tshiab thiab txhim kho kev ruaj ntseg ntawm qhov loj me thiab koom haum.

(3) kev kho tshuaj thiab kev laus: txhawm rau txhim kho nws lub zog, α titanium alloy thiab ruaj khov β titanium alloy tsis tuaj yeem txhim kho kev kho cua sov, tsuas yog txhawm rau tsim khoom α β titanium alloys thiab metastable β titanium alloys muaj me me ntawm α theem tuaj yeem ntxiv dag zog los ntawm kev kho tshuaj thiab kev laus.

Ib qho ntxiv, txhawm rau ua kom tau raws li qhov tshwj xeeb xav tau ntawm cov khoom ua haujlwm, kev lag luam kuj tseem siv ob qho ua kom sov, ua kom sov sov, kho cua sov, kho cua sov kom deformation thiab lwm yam txheej txheem kho cua sov.
