Titanium thiab titanium alloy hlau txheej txheej txheem
Titanium thiab titanium alloy xov hlau yog dav siv nyob rau hauv aerospace, petrochemical, kev kho mob thiab kev noj qab haus huv, tsheb, kev tsim kho, kev ua si thiab leisure khoom thiab ntau lwm yam teb. Tam sim no, ntau tshaj 80% ntawm titanium thiab titanium alloy hlau yog siv los ua vuam hlau; lawv tuaj yeem ua rau hauv meshes li seawater lim, lim dej ntshiab, lim tshuaj, thiab lwm yam .; lawv yog siv los tsim cov fasteners, load-bearing Cheebtsam, springs, thiab lwm yam .; lawv yog siv los tsim cov cuab yeej kho mob, cog cov yas yas, kho pob txha taub hau, thiab lwm yam .; titanium nickel alloy xov hlau yog siv los tsim cov kav hlau txais xov satellite, iav tsom iav, thiab lwm yam .; Hauv kev lag luam electroplating thiab dej kho, titanium thiab titanium alloy hlau yog siv los tsim ntau yam electrodes.
titanium hlau thiab titanium alloy hlau daim duab yog cov hlau yas ua txheej txheem nyob rau hauv uas cov hlau pas nrig los yog hlau dawb paug yog rub tawm ntawm lub qhov tuag ntawm cov hlau kos duab tuag nyob rau hauv qhov kev txiav txim ntawm lub kos duab quab yuam los tsim me-section titanium thiab titanium alloy nyob ntawm tej. . Muaj ntau ntau txoj kev kos duab:
(1) Tsau tuag daim duab: Tsau tuag yog ib qho ntawm cov txheej txheem tseem ceeb rau cov hlau hlau. Cov ntaub ntawv tseem ceeb ntawm kev kos duab tuag yog cemented carbide, pob zeb diamond ntuj, pob zeb hluavtaws, thiab pob zeb diamond polycrystalline. Ib leeg siv lead ua pob zeb diamond tuag feem ntau yog siv rau hauv kev tsim cov hlau zoo. Titanium yog cov khoom siv nyuaj rau kev ua haujlwm, tsis yog vim nws qhov siab deformation tsis kam thiab tsis tshua muaj plasticity, tab sis kuj yog vim muaj teeb meem adhesion thaum lub sijhawm ua, uas muaj kev cuam tshuam tsis zoo rau saum npoo ntawm cov khoom. Txhawm rau txhim kho qhov zoo ntawm titanium hlau, kev kho saum npoo yuav tsum tau ua ua ntej kos duab los tsim cov kev mob uas tsim nyog rau cov roj nplua nyeem kom ua raws li cov khoom siv ntawm cov hlau hauv ntau qhov ntau, uas yog, los tsim cov txheej txheem roj nplua nyeem. Nws suav nrog kev kho oxidation saum npoo, kev kho fluorophosphate, tooj liab, chromium, npib tsib xee thiab tin plating thiab lwm cov yeeb yaj kiab hlau, cov kev kho oxidation thiab txheej txheej yog feem ntau. Piv txwv li, ua ntej kos titanium hlau, me ntsis oxidation annealing yog ua, ces cov xim yog siv thiab qhuav.
(2) Cov menyuam tuag daim duab: Txij li cov menyuam tuag daim duab yog kos rau hauv lub qhov uas tsis yog kis tau tus mob, dawb do rotating rollers, feem ntau ntawm cov zawv zawg kev sib txhuam ntawm cov khoom thiab lub qhov tuag thaum lub sij hawm tsau tuag yog hloov dua siab tshiab rau hauv kev sib txhuam me me, yog li no zoo heev txo cov duab kev sib txhuam. Qhov tsis zoo ntawm cov menyuam tuag daim duab yog qhov tseeb qhov tseeb tsis yog siab npaum li cov duab kos tuag tas. Nws yog tsim rau coarse hlau kos duab, thaum taag tuag yog siv los ua kom tiav nyob rau hauv zoo hlau kos duab.
(3) Ultrasonic vibration kos duab: Txoj kev no tau tsim nyob rau xyoo 1950. Kev siv ultrasonic vibration rau cov duab tuag thaum lub sij hawm kos duab tuaj yeem txo qhov kev quab yuam thiab txhim kho tus nqi ua haujlwm.
(4) Dieless daim duab: Cov txheej txheem no siv lub kauj induction los yog laser rau hauv zos cua sov thiab soften cov hlau, thiab siv nro kom cov hlau nyias. Nws qhov zoo yog tias nws tsis tas yuav tsum tau kos duab tuag thiab roj nplua nyeem, muaj qhov deformation loj thiab ua haujlwm siab. Nws qhov tsis zoo yog qhov tsis zoo ntawm qhov tsis zoo ntawm cov khoom tiav thiab tsis ruaj khov.
(5) Lub siab-boosting tuag drawing: Cov txheej txheem no yog hais txog ib txoj hauv kev uas lub siab-boosting nozzle ntaus ntawv yog ntsia rau pem hauv ntej ntawm daim duab tuag, uas muaj peev xwm tsim ib tug tsis siv neeg siab-boosting quab yuam lubrication nyhuv thaum cov hlau yog kos. Nws qhov zoo yog tias qhov zaus ntawm cov hlau tawg tau raug txo los ntawm 4/5, lub neej ntawm cov hlau kos duab tuag tau nce ntau dua 20 zaug, thiab qhov zoo ntawm qhov chaw zoo tuaj.
(6) Coating-sheathed bundle drawing: Txoj kev no thawj zaug coated ib txheej ntawm cov pa roj carbon tsawg nyob rau saum npoo ntawm titanium hlau, ces bundles lub plated titanium hlau rau hauv ib tug tsawg-carbon steel raj, thiab ces ua bundle drawing thiab intermediate annealing. . Tom qab ua tiav mus rau qhov kawg, qhov qis-carbon steel sheath thiab txheej raug tshem tawm los ntawm sulfuric acid pickling. Nws qhov zoo yog kev ua haujlwm siab thiab cov nqi tsim khoom tsawg.
(7) Sheathed-chip extrusion: Cov txheej txheem no tau tsim los ntawm Tohoku University hauv Nyij Pooj thiab feem ntau yog siv rau kev ua ntawm TiNi cov duab nco alloy hlau. Nws tuaj yeem txhim kho cov khoom zoo thiab txo cov nqi tsim khoom. Ua ntej, ib daim ntawv sib xyaw ua ke ntawm cov ntawv sib txawv yog npaj los ntawm txheej thiab dov. Lub thickness piv ntawm ntau txheej hlau nyob ntawm seb cov tshuaj muaj pes tsawg leeg. Tom qab ntawd, cov ntawv dov coated yog txiav rau hauv daim nyias nyias, thiab cov chips txiav tau ntim rau hauv ib lub thawv los ua ib daim ntawv billet, thiab cov billet yog extruded rau hauv ib tug nyias pas nrig, thiab ces ua tiav rau hauv nyias hlau. Thaum kawg, cov hlau sib xyaw yog hloov mus rau hauv qhov xav tau intermetallic compound hlau los ntawm kev kho thermal diffusion.
(8) Nruam dov ntawm hlau los ntawm plaub-cov menyuam hlau zeb zeb: Hom zeb no muaj plaub yob ua ib lub voj voog. Thaum ua hauj lwm, ib tug active yob tsav lwm lub yob rau tig. Ntau qhov zoo li no tsim ib pawg txuas txuas txuas ntxiv los tsim cov titanium alloy hlau, yog li txhim kho cov khoom tsim tau zoo thiab tawm los ntawm cov hlau.
Titanium thiab titanium alloy xov hlau tau dhau los ua cov thawj coj hauv kev lag luam khoom siv nrog lawv cov kev ua tau zoo thiab kev siv dav dav. Lub nruam innovation thiab kev loj hlob ntawm kev kos duab technology muab lub zog lav rau kev tsim thiab siv cov khoom siv no. Peb muaj laj thawj ntseeg tias yav tom ntej, titanium thiab titanium alloy hlau yuav txuas ntxiv mus ua lub luag haujlwm tseem ceeb hauv ntau yam kev lag luam thiab coj kev yooj yim dua thiab xav tsis thoob rau peb lub neej. Yog tias koj xav paub ntau ntxiv txog titanium thiab titanium alloy hlau daim duab txheej txheem, koj tuaj yeem ua raws li peb ~ Yog tias koj muaj kev xav tau ntawm qhov no, koj tuaj yeem tiv tauj peb!
