Titanium alloy nyob rau hauv kev nruj me ntsis, tshwj xeeb tshaj yog lub zog tseem ceeb tshaj li lwm cov khoom siv hlau, tuaj yeem tsim lub zog ntawm cov khoom siv hlau, zoo nkauj, cov khoom lag luam zoo kawg nkaus, cov khoom siv lub teeb yuag. Nyob rau hauv tsis ntev los no titanium alloy tau siv nyob rau hauv cov dav hlau los hloov cov khoom siv titanium kom muaj zog, nyob rau hauv 300 lub zog dua li cov aluminium alloy, qhov ua haujlwm kub siab txog 500 degree. Superior corrosion resistance to alkali, chloride, chlorine organic items, nitric acid, sulfuric acid, etc. At the same time, titanium alloys in the humid environment as well as seawater media, pitting corrosion, acid corrosion, stress corrosion resistance is far more than stainless steel. Titanium alloy ua khoom lag luam kuj muaj hardness siab, siab melting point, tsis-toxic, tsis muaj hlau thiab sib nqus thiab lwm yam ntxwv.
Raws li cov koob meej saum toj no ntawm kev ua tau zoo heev, titanium alloy tau thawj zaug siv hauv kev tsav dav hlau. Xyoo 1953, Tebchaws Asmeskas Douglas tuam txhab thawj zaug rau cov khoom siv titanium-muaj nyob hauv cov ntaub ntawv dc2t hauv cov firewalls, ua tiav cov txiaj ntsig zoo. Hauv Aerospace teb, titanium alloy tau siv thawj zaug nyob rau hauv tus kiv cua, tawv nqaij thiab tsaws tag nrho cov cav, ua rau lub dav hlau dav hlau txog 30% ~ 35%. Titanium alloys kuj tseem tau zoo siv nyob rau hauv lub siab-resistant plhaub pip pa, antab Tsis tas li ntawd, vim yog Titanium alloy muaj zoo biocompatibility, forsicors thiab cov duab hniav sib xyaw ua ke, thiab cov hniav sib xyaw hniav thiab cov hniav sib xyaw ua ke Alloys tseem siv nyob rau hauv cov chaw kho mob raws li cov khoom lag luam zoo li cov khoom siv feming, 5v {{14} {{14} -2
Teeb meem nyob rau hauv kev ua cov titanium alloys
(1) Kev tiv thaiv me me: qhov no yog qhov pom tseeb ntawm cov txheej txheem txiav ntawm titanium alloy cov ntaub ntawv. Nyob rau hauv cov txheej txheem kev txiav thiab machining, thaj tsam ntawm cov hniav hniav loj heev, thiab hauv cov txheej txheem ntawm kev taug kev ua rau muaj qhov kub ntawm lub cuab tam.
(2) Kev ntsuas kub siab: Ntawm ib sab tes, kev deformation me me Thiab titanium alloy txiav cov txheej txheem txiav qhov ntau yog vim yog titanium alloy thermal ntawm cov phiaj ntawm lub cuab tam, ua rau kub nyob hauv qhov kub thiab txias heev.
(3) Lub thermal conductivity ntawm titanium alloy yog tsawg heev: lub cua sov tsim los ntawm kev txiav tsis yooj yim rau dissipate. Titanium Alloy Hloov Txheej Txheem yog qhov kev ntxhov siab loj, nyob rau lub sijhawm kub, yog li ntawd ntau cov pa sib sau ua ke, yog li qhov kev txiav ntawm rab riam, kom muaj kev sib tw ntawm cov riam muag, nrawm dua qub kev hnav.
(4) Cov tshuaj lom neeg ntawm titanium alloy yog heev loj heev: ntawm cov khoom kub, titanium alloy yog yooj yim los ua kom muaj qhov ua kom nrawm nrawm ntawm kev tsim cov pits ntawm crescent pits. Tab sis cov txheej txheem txiav ntawm titanium alloy yog yeej nqa tawm ntawm qhov kub. Thaum qhov kev txiav kub siab rau qee yam, cov nitrogen thiab oxygen lwg me me hauv huab cua thiab titanium cov khoom siv tau yooj yim tsim cov tshuaj lom neeg, ua rau cov tawv nqaij ntawm lub tawv tawv tawv. Ntxiv mus, cov yas deformation ntawm cov machined nto ntawm cov txheej txheem ua haujlwm ntawm titomenon txias, thiab cov khoom hnyav thiab cov khoom siv ua kom tawv nqaij ntawm cov khoom siv workpiece. Cov xwm txheej no nce thev kev coj hnav thiab txo qis zog ntawm lub titanium cov khoom.
(5) Cov cuab yeej yooj yim heev rau kev hnav: Tuam kev hnav yog qhov tshwm sim ntawm cov khoom siv kub thiab cov khoom siv ntsuas kub, nws yog qhov kev pab cuam kub heev, nws yog qhov kev pab cuam kub heev, nws yog qhov kev pab cuam kub thiab cov khoom siv ua kom muaj zog Yog li kev txiav ntawm titanium alloy cov ntaub ntawv yuav tsum xyuam xim rau ob yam, yog txhawm rau txhawm rau txiav cov cuab yeej tsis tshua muaj, cov cuab yeej txiav, cov cuab yeej txiav yog ib txoj hauv kev los txhim kho qhov nruj ntawm cov cuab yeej.
Vim yog cov kev ua haujlwm siab ntawm titanium alloys, tsis muaj thermal conductivity ua rau muaj kev kub hnyiab, ua tsis tau zoo, ua rau lub neej luv luv thiab cov nqi machin sai. Cov ua rau ntawm cov twj hnav suav nrog kev sib txhuam tshuab lossis tshuaj rau lub cev thiab tshuaj lom neeg raws li kev txiav txim siab thiab txiav kub. Txog kev nyuaj ntawm titanium alloy txiav thiab machining, cov khoom siv xaiv tau ua kom tau raws li qhov kev xav tau ntawm kev ua haujlwm siab, cov tshuaj ruaj khov thiab xim liab zoo. Tam sim no lub lag luam pom tau qhov zoo tshaj plaws ntawm kev ua cov cuab yeej titanium alloy, yog li lub carbide coated cov cuab yeej tseem ceeb ntawm titanium alloy txiav thiab ua lag luam.
Cov cuab yeej txiav tsoos uas tsis haum rau kev siv cov binary tic los yog ua rau muaj kev tsis yooj yim sua kom muaj kev ua tiav ntawm cov cuab yeej.ezugwn li al. Siv lub High-ceev steel substrate crn thiab ticn txheej thiab uncoated tungsten thiab cob cov cuab yeej carbide ntawm TC4 titanium alloy txiav. Txoj kev tshawb no tau pom tias kev pabcuam lub neej ntawm CRN coated cuab yeej siv sijhawm ntev dua li ticn coated cuab yeej thiab uncoated carbide cov cuab yeej thiab uncoated carbide carbide. Nyob rau tib lub sijhawm, kev sim ntawm Ti6A44V titanium alloy siv cov txheej txheem tib yam nkaus xwb uas yog cov txheej txheem ntau dua
Nyob rau hauv xyoo tsis ntev los no, vim txheej txheem thiab txoj kev npaj cov txheej txheem txawv teb chaws, thiab muaj ntau txheej txheej ua haujlwm, yog li cov cuab yeej ua haujlwm zoo dua, yog li ntau cov cuab yeej siv tau zoo dua qub Titanium alloy ua haujlwm, thiab qhia tau zoo tshaj, Daim Duab 2 qhia tau cov cuab yeej carbide feem ntau siv cov cuab yeej tsis ntev los no.
Txoj kev kawm txhim kho yav tom ntej ntawm carbide coated cuab yeej
(1) diversification ntawm cov txheej txheej muaj pes tsawg leeg. Nyob rau hauv tib txheej kom ntxiv cov ntsiab tshiab (xws li ntxiv zr thiab v yuav txhim kho cov txheej txheej tawv, thiab lwm yam khoom siv tau txhim kho cov khoom siv ntau txheej, ntxiv rau cov khoom siv ntau dua, ntxiv rau cov khoom siv ua kom zoo dua qub, ntxiv Txheej txheej muaj kuj tau tsim los ntawm tin, tialn, tials, tisnsin, tisn, thiab yog li kaum ob ntawm cov khoom txheej. (Daim duab 3) Txhawm rau kom tau raws li cov kev xav tau sib txawv hauv kev txiav cov kev tsim, cov txheej txheej txheej txheej txheej txheej txheej tshiab yuav muaj cov kev cia siab rau kev txhim kho.
(2) Txiav ntsuab. Tam sim no, Tuam Tshoj cov machining yog siv nyob rau hauv cov teeb meem ntub dej, thiab tib lub sijhawm sib txawv ua rau muaj kev phom sij rau ib puag ncig, thiab tib lub sijhawm ua rau muaj kev phom sij rau ib puag ncig, thiab ib puag ncig kev ua phem rau cov khoom siv paug rau ib puag ncig ua rau ib puag ncig ua rau ib puag ncig ua rau muaj kev phom sij. Thiab los ntawm kev ua cov kev ua tiav nqi, txiav cov kua dej rau 14% rau 16% ntawm tag nrho tus nqi, cov cuab yeej tsuas yog 2% rau 4%. Cov kev tshawb fawb tau pom tias yog 20% ntawm cov txheej txheem txiav yog machined tov nrog cov cuab yeej txheej txheem, tag nrho cov nqi tsim khoom tuaj yeem txo los ntawm 1.6% [16]. Tsis tas li ntawd, kev siv cov kev txiav ceev nrawm tau txhim kho machining qhov tseeb, txhim kho cov tshuab nqus tsev, thiab yog qhov tsim nyog rau machining nyias-walled ntu. Yog li ntawd, txawm hais tias los ntawm ib puag ncig kev pom ntawm kev pom lossis ntawm kev siv cov cuab yeej ntawm cov khoom siv tau yooj yim yog ib qho tseem ceeb txhawb nqa rau green machining.
Nrog rau "tau ua nyob rau hauv Suav 2025" kev tsim khoom lag luam, txo cov kev lag luam titorive, txo cov kev txhim kho ntawm cov kev lag luam tseem ceeb, txo cov kev txhim kho ntawm cov haujlwm tseem ceeb thiab muaj ntau yam kev lag luam zoo thiab muaj ntau yam kev lag luam zoo dua qub Kev txhim kho ntawm qib tag nrho ntawm kev tsim khoom lag luam yog qhov tseem ceeb tseem ceeb.
