Tshawb cov txheej txheem ntawm kos titanium alloy hlau

Titanium alloy hlau, raws li cov khoom siv tseem ceeb hauv kev lag luam niaj hnub no, muaj ntau yam kev siv, npog thaj chaw tseem ceeb xws li aerospace fasteners, cov neeg siv khoom siv hluav taws xob (3C cov khoom), cov iav tsom iav, cov khoom siv tsheb, cov khoom siv kho mob thiab cov khoom siv vuam. Txhawm rau kom paub qhov tseeb ntawm cov khoom siv hlau ua haujlwm siab, cov txheej txheem kev kos duab txias tau dhau los ua ib qho tseem ceeb ntawm kev ua, tshwj xeeb tshaj yog nyob rau hauv txoj kab uas hla ntawm cov xaim yuav tsum loj dua qhov kawg cov khoom 30% -40%. Hauv daim ntawv no, peb yuav tham txog ntau yam tseem ceeb uas cuam tshuam rau kev kos duab ntawm titanium alloy hlau thiab cov tswv yim ua kom zoo.
1. Kev tswj nruj ntawm cov khoom siv raw zoo
Tshuaj muaj pes tsawg leeg: cov tshuaj muaj pes tsawg leeg ntawm titanium alloy ncaj qha cuam tshuam rau nws lub cev thiab txhua yam khoom. Kev tswj nruj ntawm cov ntsiab lus ntawm H, O, N, Fe, Si thiab lwm yam tseem ceeb yog qhov tseem ceeb, xws li H lub ntsiab lus yog ib qho yooj yim los ua kom hydrogen embrittlement, yuav tsum tau nruj me ntsis saib xyuas thiab tswj nyob rau hauv qhov chaw nyab xeeb.
Qhov zoo ntawm qhov chaw: qhov saum npoo ntawm cov khoom siv raw yuav tsum tsis txhob muaj cov kab nrib pleb, folding, caws pliav thiab lwm yam tsis xws luag, cov kev tsis zoo no hauv cov txheej txheem kos duab yuav nthuav dav, ua rau lub zog poob lossis txawm tawg. Yog li ntawd, cov ntaub ntawv raw yuav tsum tau soj ntsuam nruj nreem thiab pretreatment kom paub meej tias qhov chaw du thiab tsis muaj qhov tsis xws luag.
2. Kev ua kom zoo ntawm cov txheej txheem kho cua sov
Kev kho cua sov ua lub luag haujlwm tseem ceeb hauv kev kos duab ntawm titanium alloy hlau. Annealing kev kho mob (xws li pretreatment annealing, intermediate annealing thiab tiav cov khoom annealing) yog tsim los txo kev ua hauj lwm hardening, txhim kho lub elongation thiab plasticity ntawm cov khoom, thiab tsim kom muaj tej yam kev mob rau lub tom ntej no daim duab txheej txheem. Tsim nyog annealing system tuaj yeem txhim kho lub koom haum cov qauv ntawm cov khoom, txhim kho cov duab kos.
3. Kev kos pwm xaiv thiab tsim
Cov khoom siv pwm: kos pwm feem ntau siv cov cemented carbide (xws li YK6, YK8) thiab cov khoom siv pob zeb diamond. Cemented carbide yog dav siv rau nws qhov siab hardness thiab zoo abrasion tsis kam, thaum lub pob zeb diamond kos duab tuag tau dhau los ua thawj qhov kev xaiv rau kev nplua thiab ultra-nplua hlau kos duab vim nws cov hardness tsis tshua muaj siab thiab abrasion tsis kam, txawm hais tias nws yog kim thiab nyuaj rau txheej txheem. .
Tuag tsim: Tus tsim ntawm cov tuag yuav tsum tau kho raws li cov hlau specifications thiab kos duab yuav tsum tau. Cov pwm pwm feem ntau muaj xws li nkhaus thiab conical pwm, uas yog haum rau txawv diameters ntawm hlau. Kev tsim ntawm qhov tuag qhov tseem yuav tsum tau ua tib zoo xav, suav nrog lub khob nkag, lub khob hliav qab ua haujlwm, siv txoj siv sia thiab tawm lub khob hliav qab thiab lwm yam, kom ntseeg tau tias cov hlau hauv cov txheej txheem kos duab du deformation thiab ruaj khov zoo.

4. Kev kos duab cov txheej txheem ntawm kev tswj kom zoo
Txoj kev deformation: chav tsev kub tensile plasticity ntawm titanium alloy yog tsawg, yog li nws yog ib qho tsim nyog los tswj txoj kev deformation, kom tsis txhob muaj cov hlau lead ntau dhau. Los ntawm maj mam nce tus nqi ntawm deformation, maj mam txhim kho cov txheej txheem ntawm cov khoom, txhim kho lub zog tensile.
Tag nrho cov deformation: Qhov nce ntawm tag nrho cov deformation yuav txhim kho lub zog ntawm titanium alloy hlau, tab sis tib lub sij hawm, nws tseem yuav ua rau hnyav ua hauj lwm hardening thiab txo toughness. Yog li ntawd, nws yog ib qho tsim nyog yuav tsum sib npaug ntawm kev sib raug zoo ntawm lub zog thiab toughness raws li cov kev xav tau tshwj xeeb los txiav txim siab qhov zoo tag nrho deformation.
Daim duab nrawm: daim duab nrawm yog ib qho tseem ceeb cuam tshuam rau kev ua haujlwm ntawm titanium alloy hlau. Ua kom cov duab nrawm tuaj yeem txhim kho cov khoom tsim tau thiab txuag lub zog, tab sis yuav tsum tau ua kom cov hlau zoo thiab ruaj khov ntawm cov txheej txheem kos duab. Los ntawm kev kho cov duab nrawm, tus cwj pwm deformation thiab microstructure ntawm cov khoom tuaj yeem ua kom zoo.
Cov txheej txheem kev kos duab ntawm titanium alloy hlau suav nrog kev tswj xyuas zoo thiab kev ua kom zoo ntawm ntau yam tseem ceeb. Los ntawm kev tswj hwm cov khoom zoo ntawm cov ntaub ntawv raw, optimizing cov txheej txheem kev kho cua sov, xaiv qhov tsim nyog kos duab tuag thiab ua tib zoo tswj cov kev tsis sib xws ntawm cov txheej txheem kos duab, kev ua tau zoo thiab kev ua tau zoo ntawm titanium alloy hlau tuaj yeem txhim kho kom tau raws li qhov xav tau ntawm ntau yam kev lag luam. daim ntawv thov.
