Titanium hlab muaj lub zog siab, muaj zog zoo, muaj zog, thiab muaj kev siv rau hauv aerospace, nkoj tsis zoo, thiab kev lag luam siv tshuaj. Txhawm rau siv cov raj titanium yas, nws yog ib qho tsim nyog los kawm lawv weldability. Cov nram qab no nyob rau hauv cov txheej txheem vuam ntawm titanium kav, muab kev pab siv rau yav tom ntej vuam ntawm titanium kav.
01 Cov Khoom Siv Vuam
Vuam Hlau: erti-2 vuam txoj kev: gtaw (phau ntawv tungsten inert roj vuam)
Cov roj tiv thaiv roj: Siv cov pa roj txheem sib cav nrog kev ua kom zoo nkauj ntawm 99.995% thiab cov ntsiab lus dej tsis ntau tshaj li 400℃hauv kev sib koom ua ke vuam.
02 npaj ua ntej vuam
(1) Groove ua
Tom qab txiav lub titanium raj, siv ib alumina sib tsoo tshuab mus txhuam tus zawj, raws li qhia hauv daim duab hauv qab no. Cov zawj txheem yuav tsis ua rau overheating lossis discoloration ntawm cov khoom siv hauv paus.
(2) Groove thiab vuam hlau ntxuav
A, ntxuav sab hauv thiab sab nraud ntawm 50 hli ntawm ob sab ntawm cov zawj, thiab cov txheej txheem ntxuav yog li nram no:
Polishing nrog lub tshuab polishing → sanding nrog cov xuab zeb log → tu nrog Acetone.
Tom qab tu, vuam ua haujlwm tsis tuaj yeem nqa ncaj qha. Lub lag luam tsuas yog nqa tawm tom qab lub zawj kawg lub ntsej muag yog qhuav. Yog tias qhov kev tso kawm lub sijhawm ntau tshaj 2 teev, cov zawj yuav tsum tau ntxuav dua lossis tiv thaiv nrog tus kheej- cov ntaub nplaum.
B, The Vuam hlau yuav tsum tau so huv si nrog daim txhuam cev dipped hauv acetone thiab khaws cia hauv cov vuam hlau lub thawv.
C, cov neeg ua haujlwm yuav tsum hnav hnab looj tes huv si thaum vuam.
