Hauvtitanium alloytuag forging txheej txheem, qhov teeb meem oxidation thaum lub sij hawm billet cua sov ncaj qha cuam tshuam rau kev siv hlau thiab cov nqi khoom. Daim ntawv no, raws li kev soj ntsuam kev tshawb fawb ntawm titanium alloys xws li BT3-1, BT20, OT4-1, thiab PT7M, txheeb xyuas qhov cuam tshuam ntawm kev kho mob ua ntej oxidation, iav enamel txheej, cua sov nruab nrab optimization, thiab cov txheej txheem kho saum npoo ntawm qhov zoo thiab cov khoom siv ntawm forgings. Cov txheej txheem txheej txheej txheej txheej oxidation tswj tau raug npaj, muab cov ntaub ntawv siv rau kev ua kom zoo ntawm titanium alloy forging txheej txheem.
Titanium alloys yog dav siv hauv aerospace, kev kho mob, thiab lwm yam kev lag luam vim lawv lub zog tshwj xeeb thiab corrosion kuj. Txawm li cas los xij, lawv cov tshuaj muaj zog heev ua rau lawv muaj kev cuam tshuam nrog cov ntsiab lus xws li oxygen thiab nitrogen thaum lub sij hawm siab -kub cua sov los ua ib txheej oxide nkig, ua rau cov khoom siv plasticity tsawg thiab nce kev ua haujlwm siab. Yog li ntawd, txo qis los yog tshem tawm oxidation thaum lub sij hawm cua sov txheej txheem ntawm titanium alloy forging blanks tau dhau los ua ib qho kev sib tw tseem ceeb rau kev txhim kho cov khoom siv thiab txo cov nqi tsim khoom.
(1) Kev tswj cua sov hauv lub qhov cub hluav taws xob: Thaum cua sov hauv lub qhov cub hluav taws xob, qhov kub yuav tsum tau tswj nruj me ntsis saum toj no allotropic transformation kub thiab lub sij hawm tuav yuav tsum tsawg dua los yog sib npaug li 1 teev kom tsis txhob pom tseeb cov pa nqus ntawm qhov chaw. Cov txheej txheej oxide tsim tuaj yeem raug tshem tawm zoo los ntawm kev xuab zeb blasting, thiab cov khoom siv poob yuav tsum tswj tsis pub dhau 5%.
2) Pseudo-liquefaction txheej cua sov thev naus laus zis rau cov khoom siv xoob: Cov cuab yeej no suav nrog kev faus cov pob zeb hauv ib qho pseudo-liquefaction txheej uas muaj liquefaction granular media (xws li alumina hmoov) rau cua sov, siv lub zog sib txheeb ntawm cov xov xwm hais los txhim kho cov cua sov. Cov kev sim qhia tau hais tias nws qhov kev hloov pauv hluav taws xob yog 1.5 qhov kev txiav txim siab ntau dua li ntawm lub tshuab hluav taws xob yuam kev, nce mus txog qib ntawm lub qhov cub ntsev molten. Cov thev naus laus zis no tuaj yeem ua tiav cov cua kub ceev thiab zoo ib yam ntawm cov billet, txo lub sijhawm cua sov los ntawm 40% mus rau 60%, thaum txo qis oxidation nyiam los ntawm kev sib cais ntawm qhov nruab nrab, txo cov oxide txheej thickness ntau dua 80%.
Sandblasting tom qab tuag forging yog ib kauj ruam tseem ceeb hauv kev txhim kho kev ua haujlwm ntawm forgings. Cov pa sandblasting tuaj yeem tshem tawm cov txheej txheej oxide thiab roj-absorbing txheej, txo qhov roughness Ra tus nqi qis dua 3.2 μm, thaum tib lub sijhawm txhim kho plasticity los ntawm kev ntxiv dag zog rau saum npoo. Rau cov blanks nrog iav enamel txheej, lub sandblasting siab yuav tsum tau tswj nyob rau hauv qhov ntau ntawm 0.3-0.5 MPa kom tsis txhob muaj kev puas tsuaj ntau dhau rau cov khoom siv hauv paus.
Cov lus xaus:
1. Kev sib koom ua ke ntawm kev ua ntej - oxidation kev kho mob thiab iav enamel txheej tuaj yeem tsim ib qho kev tiv thaiv dual - txheej txheej "tiv thaiv oxidation tswj + passive kev tiv thaiv kev tiv thaiv," ua rau txhim kho qhov zoo ntawm titanium alloy forgings.
2. Cov khoom siv xoob xoob pseudo-liquefaction txheej cua sov tshuab ua tiav ob lub hom phiaj ntawm kev siv cua sov kom zoo thiab oxidation tswj los ntawm kev ua kom cov cua sov hloov tshuab, ua rau nws tsim tshwj xeeb rau cov khoom loj ntawm complex- zoo li forgings.
3. Kev tswj xyuas cov txheej txheem tsis raug (kub, sijhawm, xuab zeb blasting siab, thiab lwm yam) yog qhov tseem ceeb los xyuas kom meej qhov kev ua tau zoo ntawm titanium alloy forgings; txheej txheem txheej txheem specifications yuav tsum tau tsim raws li ib tug tshwj xeeb alloy qib.
