Titanium Qib 2thiabQib 5 (Ti-6Al-4V)yog ob qho ntawm cov khoom siv titanium ntau tshaj plaws hauv kev lag luam thiab kev siv kho mob.
Txawm li cas los xij, lawv sib txawv hauv lub zog, kev tiv thaiv corrosion, nqi, thiab kev tsim khoom. Kev xaiv cov khoom tsis raug yuav ua rau tus nqi tsis tsim nyog nce lossis txawm tias qhov tsis ua haujlwm ntxov ntxov.
Nyob rau hauv tsab xov xwm no, peb piv Titanium Qib 2 vs Qib 5 nyob rau hauv cov nqe lus ntawm cov tshuaj muaj pes tsawg leeg, mechanical zog, corrosion kuj, ua, nqi, thiab daim ntawv thov los pab koj txiav txim siab.
Qib 2 yog kev lag luam ntshiab titanium thiab muaj kev tiv thaiv corrosion zoo heev, yooj yim rau tshuab thiab fabricate; Qib 5 (Ti-6Al-4V) yog ib qho + titanium alloy, dav suav hais tias yog feem ntau siv siab -lub zog titanium alloy, nrog ultra- siab zog raws li nws cov kev sib tw tseem ceeb. Kev xaiv cov khoom siv tsis raug tuaj yeem ua rau tus nqi nce thiab, nyob rau hauv qhov xwm txheej phem tshaj plaws, cov plua plav tiv thaiv tsis ua haujlwm thaum ntxov. Kab lus no yuav ua kom tob sib piv rau 6 yam: tshuaj lom neeg muaj pes tsawg leeg, cov khoom siv kho tshuab, kev tiv thaiv corrosion, kev ua haujlwm thiab vuam, nqi, thiab cov ntawv thov raug.
2.Txoj kev sib piv kev txheeb xyuas
1. Tshuaj muaj pes tsawg leeg thiab kev faib tawm
Qib 2 yog alpha hom ntshiab titanium nrog ib zaug alpha theem microstructure thiab cov pa oxygen ntawm kwv yees li 0.15 ~ 0.25%, kom ntseeg tau zoo heev plasticity thiab corrosion kuj. Qib 5 tsim cov qauv alpha + beta dual theem los ntawm kev ntxiv 6% txhuas (stable alpha theem) thiab 4% vanadium (stable beta phase), uas tuaj yeem ua kom muaj zog ntxiv los ntawm cov khoom siv tshuaj tua hluav taws kub.
2. Mechanical Properties - Qhov txawv ntawm Core
Lub zog tensile ntawm Qib 5 yog kwv yees li 2.5 - 3 npaug ntawm Qib 2, thiab nws lub zog tawm los kuj tseem ceeb dua. Qhov no tso cai rau Qib 5 qhov sib dua thiab nyias dua piv rau thaum lawv raug cov khoom sib npaug. Tab sis Qib 2 muaj qhov elongation ntau dua (kwv yees li 20% vs 12%), plasticity zoo dua, thiab tsis tshua muaj pob txha. Nyob rau hauv cov nqe lus ntawm qaug zog, Qib 5 muaj qhov kev qaug zog ntau dua li Qib 2 thiab feem ntau yog siv rau cov khoom siv hluav taws xob xws li cov dav hlau dav hlau thiab cov hlua txuas.
Raws li cov qauv kev lag luam xws li ASTM B348 thiab ASTM B265, cov khoom siv kho tshuab ntawm ob qib no txawv heev.
3. Corrosion kuj
Qib 2 ntshiab titanium muaj TiO ₂ oxide zaj duab xis ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom TiO ₂ oxide zaj duab xis ntawm nws qhov chaw, uas ruaj khov rau cov dej hiav txwv, cov roj chlorine ntub dej, nitric acid, acetic acid, thiab lwm yam. Qib 5 ntawm titanium alloy yog me ntsis corrosion resistant nyob rau hauv muaj zog txo acids (piv txwv li, boiling hydrochloric acid) los yog nyob rau hauv siab - kub siab concentration halides vim muaj txhuas thiab vanadium, tab sis nws yog tseem siv tau nyob rau hauv feem ntau muaj kev lag luam ib puag ncig. Yog tias koj xav tau kev tiv thaiv corrosion hnyav hauv koj qhov project, qib 2 yuav tsum nyob rau saum koj daim ntawv teev npe.
4. Kev ua thiab vuam muaj peev xwm
Cold forming: Qib 2 tuaj yeem ua tau yooj yim txias khoov, stamped, thiab sib sib zog nqus nqus; Qib 5 txias sib sau ua rau nws tawg thiab yuav tsum tau rhuab mus rau 600-800℃rau kub sib sau.
Machining: Qib 2 yog qhov tsis zoo rau nws txoj kev nyiam ua rau rab riam thiab yuav tsum tau ceev heev nrog rau ntau cov coolant; Qib 5 yog qhov nyuaj rau lub tshuab thiab ua tiav zoo tshaj plaws ntawm cov khoom siv nrog kev txiav ceev, zoo rigidity, thiab qis txiav ceev thiab nruj kev teeb tsa raug pom zoo los txhim kho lub neej ntawm cov cuab yeej, vim tias titanium alloys rhiab rau cov cua sov thaum lub sij hawm machining.
Vuam: Qib 2 zoo heev rau vuam thiab feem ntau tsis kho cua sov tom qab vuam. Qib 5 muaj peev xwm weldability, tab sis nws yooj yim rau absorbing hydrogen thiab oxygen impurities. Nws raug nquahu kom ua kev ntxhov siab rau kev ntxhov siab tom qab vuam, txwv tsis pub muaj kev pheej hmoo ntawm embrittlement thiab txo ductility.
5. Tus nqi sib txawv
Hais txog cov nqi ntawm cov khoom siv, Qib 5 feem ntau yog 20-50% kim dua Qib 2. Tab sis qhov sib txawv ntawm cov nqi ntau dua los ntawm kev ua: Qib 5 qhov kub sib sau, nyuaj txiav, thiab tom qab vuam cov cua sov tuaj yeem ua ob npaug lossis txawm tias nce tus nqi ntawm cov khoom kawg.
