Titanium alloy forging ua kub tswj thiab ua tshuab

Dab tsi yog titanium forging processing technologies? Kev txhim kho tas mus li ntawm cov tshuab tsim khoom kuj tau coj cov txiaj ntsig zoo rau ntau cov ntaub ntawv forging. Titanium alloy forgings yog cov khoom siv ua haujlwm ntau thiab tuaj yeem siv rau ntau qhov chaw. Titanium forging processing tseem yuav txhim kho durability, nyob rau hauv niaj hnub kev lag luam kev lag luam, kev ua cov titanium alloy forgings yog undoubtedly ib tug nyuaj txoj hauj lwm. Nws cov khoom tshwj xeeb ntawm lub cev thiab tshuaj lom neeg ua rau kev tswj xyuas qhov kub thiab txias ua lub tshuab tseem ceeb. Yog li yuav ua li cas thiaj tswj tau qhov kub thiab txias thaum ua kom zoo ntawm forgings? Cia peb saib ntawm kev tswj qhov kub thiab txias ntawm titanium alloy forgings.

Cov muaj pes tsawg leeg ntawm qhov kaj thiab tsaus me ntsis ntawm titanium forgings txawv. Cov chaw ci ntsa iab qhia cov ntsiab lus siab ntawm titanium oxide, thiab qhov tsaus me ntsis pom cov ntsiab lus siab ntawm carbon. Lub thickness ntawm ob txheej ntawm titanium alloy khoom ncav cuag 3 μm thiab tsis sib tshooj. Nws ntseeg tau tias cov txheej txheej tuab ntawm cov titanium forgings yog qhov tshwm sim ntawm kev kho cua sov nruab nrab ntev thaum xaim ntau lawm. Yog li ntawd, qhov zoo tshaj plaws scenario yog tias annealing rau 15 feeb tsis muaj kev cuam tshuam rau kev hloov cov khoom ntawm cov muaj pes tsawg leeg. Lub xub ntiag ntawm cov pa roj carbon monoxide nyob rau saum npoo ntawm cov hlau yuav yog vim muaj cov roj nplua nyeem uas muaj cov graphite uas siv thaum lub sij hawm kev kos duab, nyob rau saum npoo ntawm cov hlau thiab tom qab ntawd lo rau lub sij hawm annealing txheej txheem.

Cov nyhuv tib yam tau pom nyob rau hauv machining ntawm titanium forgings, qhov twg impurities tshwm nyob rau saum npoo tom qab ob peb lub voj voog ntawm kev ua haujlwm vim lubricants. Lub polished nto muaj ib tug uniform muaj pes tsawg leeg. Tag nrho cov hlau yog them los ntawm ib txheej oxide nrog lub thickness tsawg tshaj 20 nm. Raws li qhov no, qhov no yuav tsum muaj kev cuam tshuam zoo rau kev tiv thaiv corrosion nyob rau hauv dynamic tej yam kev mob, vim hais tias ib tug nyias oxide txheej qhia tau ntau dua saj zawg zog thiab hloov tau mus rau tej yam kev mob. load ntawm cov khoom. Qhov tsis zoo yog qhov muaj cov npib tsib xee hauv txheej txheej, txawm tias me me. Tom qab annealing ntawm cov khoom txhawb kev tsim ntawm nitrous oxide txheej nrog qhov tob txog li 80 - 150nm mus rau 50 - 60nm yam tsis muaj npib tsib xee, uas yuav ua rau muaj kev cuam tshuam zoo rau corrosion ntawm cov khoom, uas kuj yog muaj feem xyuam rau kev kho cua sov, uas ua rau kev tsim ntawm titanium thiab npib tsib xee Cov txheej txheej txheej txheej muaj oxides thiab ua rau lub thickness ntawm oxide txheej kom loj hlob.

Cov khoom siv kho tshuab ntawm cov qauv nrog qhov ua haujlwm ntev ntawm 45 hli tau ntsuas nyob rau hauv cov xwm txheej tensile zoo li qub ntawm titanium forging universal kuaj tshuab nrog kev thauj khoom ceev ntawm 2 mm / min. Lub hauv paus txoj kab uas hla yog siv nyob rau hauv lub zog kev ua tau zoo xam. Kuaj 3 - 5 cov qauv ntawm txhua qhov kev sim. Cov pa hluav taws xob muaj zog σ0.2, qhov kawg ntawm lub zog σu thiab cov txheeb ze elongation mechanical tensile xeem cov txiaj ntsig qhia tau hais tias annealing muaj txiaj ntsig zoo rau lub zog lub zog ntawm cov hlau hauv cov txheej txheem. Lub zog muaj zog ntawm nanostructure zoo dua li cov khoom siv microstructure titanium alloy. Lub zog ua haujlwm yog 1.3 ~ 1.5 npaug siab dua. Polishing stretched titanium alloy khoom hlau tuaj yeem txhim kho cov khoom zoo li qub ntawm nanostructured alloy los ntawm 18%. Qhov txheeb ze elongation ntawm tag nrho cov qauv yog 51-53%.

Kev ua cov titanium forgings yuav ua rau cov ntaub ntawv nrog kev ua tau zoo dua. Ntau cov khoom yuav muaj kev cuam tshuam zoo dua rau kev tsim khoom thiab kev thov tom qab forging. Yog hais tias koj xav tau forging cov ntaub ntawv, koj yuav tsum nrhiav peb cov kws manufacturers.

Titanium alloy, nrog nws cov cuab yeej zoo heev, zoo corrosion kuj thiab tsis tshua muaj siab, yog dav siv hauv aviation, aerospace, kev kho mob thiab lwm yam. Txawm li cas los xij, kev ua haujlwm ntawm titanium alloys yog qhov nyuaj thiab kim, tshwj xeeb tshaj yog thaum kev ua haujlwm forging. Kev tswj qhov kub thiab txias yog qhov tseem ceeb los xyuas kom meej qhov zoo ntawm forgings. Yog tias qhov kub thiab txias dhau lawm, cov nplej yuav ntxhib thiab cov khoom siv kho tshuab yuav txo qis; yog tias qhov kub thiab txias qis dhau lawm, cov kab lis kev cai ciam teb yuav tshwm sim, cuam tshuam rau nws lub neej kev pab cuam. Yog li ntawd, yuav ua li cas thiaj tswj tau qhov kub thiab txias tau dhau los ua tus yuam sij rau kev ua cov titanium alloy forgings.

⑴ Preheat. Ua ntej titanium alloy forgings ua tiav, lawv yuav tsum tau preheated kom ncav cuag qhov kub thiab txias. Qhov no tuaj yeem txo qhov kub thiab txias thaum ua haujlwm thiab tsis txhob tawg. Lub preheating kub yog feem ntau tswj ntawm 800-1000 degree , thiab qhov tshwj xeeb kub yuav tsum tau txiav txim raws li lub thickness thiab cov khoom ntawm lub forging.

⑵ Tswj qhov kub thiab txias. Forging kub yog qhov tseem ceeb kub thaum lub sij hawm ua cov titanium alloy forgings, uas ncaj qha cuam tshuam rau lub grain qauv thiab kev ua tau zoo ntawm cov forgings. Feem ntau hais lus, qhov kub forging yuav tsum tau tswj nyob rau hauv theem cheeb tsam kom ntseeg tau tias cov nplej refinement. Rau cov titanium alloys, xws li TC4, TC6, thiab lwm yam., forging kub yog feem ntau tswj ntawm ib ncig ntawm 850-950 degree .

⑶ Tswj kom txias ceev. Tom qab forging tiav lawm, nws yuav tsum tau txias kom nws nkag mus rau hauv lub xeev ruaj khov sai li sai tau. Kev tswj cov cua txias yuav tsum tau txiav txim siab raws li cov thickness thiab cov khoom siv ntawm forging. Feem ntau, nws yuav tsum tsis txhob ceev heev kom tsis txhob muaj kev ntxhov siab nyob.

Lub tuam txhab aviation tau ua tiav kev tswj xyuas qhov kub thiab txias los ntawm peb txoj kev saum toj no thaum ua cov titanium alloy forgings. Nyob rau hauv lub preheating theem, lawv siv infrared tus pas ntsuas kub los saib xyuas cov forgings nyob rau hauv lub sij hawm ntawm lub sij hawm los xyuas kom meej qhov tseeb ntawm lub preheating kub; nyob rau hauv forging theem, lawv siv lub cub tawg tiv thaiv kom raug tswj qhov kub ntawm forging; nyob rau hauv lub caij txias, lawv siv dej txias los tswj kom txias ceev. Los ntawm cov kev ntsuas saum toj no, lawv tau ua tiav qhov zoo ntawm forgings thiab txo cov nqi tsim khoom.

Tswj cov txheej txheem kub ntawm titanium alloy forgings yog tus yuam sij kom ntseeg tau qhov zoo ntawm forgings. Los ntawm preheating, tswj forging kub thiab txias npaum li cas, meej tswj ntawm kev kub ceev yuav ua tau tiav, yog li txhim kho zoo forgings.
