Tshuaj Milling Txheej Txheem Ntawm Titanium Alloys

Titanium alloy yog nyuaj rau tshuab. Traditional mechanical machining nyiam ua rau muaj kev ntxhov siab deformation thiab kev puas tsuaj ntawm qhov chaw, ua rau nws nyuaj rau kev hloov mus rau kev tsim cov khoom ntawm complex thiab precision qhov chaw. Cov txheej txheem tshuaj milling cia siab rau cov tshuaj corrosion kom ua tiav cov khoom tshem tawm. Nws muaj qhov zoo tseem ceeb hauv machining complex - zoo li qhov chaw thiab kev tsim khoom hnyav. Nws yog ib qho ntawm cov txheej txheem tseem ceeb rau precision machining ntawmtitanium alloys.

 

 

 

Tshuaj milling ntawm titanium alloys tshem tawm cov ntaub ntawv nyob rau hauv preset cheeb tsam rau txoj kev los ntawm kev xaiv cov tshuaj tiv thaiv ntawm corrosive tov thiab matrix. Lub hauv paus yog"etching{0}}dissolving-passivation" voj voog: hydrofluoric acid dissolves nto oxide zaj duab xis thiab nthuav tawm cov matrix tshiab. Nitric acid forms a dense passivation film to inhibit over-corrosion and hydrogen embrittlement. Ob leeg ua haujlwm ua ke kom tswj tau tus nqi corrosion.

Cov qauv ntawm titanium alloy cuam tshuam rau tus cwj pwm corrosion microscopically. Piv txwv li, + hom titanium alloy (Gr5) tsim cov micro- roj teeb nrog theem raws li cathode thiab theem ua anode, thiab theem dissolves nyiam. Yog li ntawd, nws yuav tsum tau kho cov txheej txheem raws li lub xeev metallurgical thiab theem piv ntawm cov hlau kom ntseeg tau tias machining uniformity.

 

 

(I) Pretreatment

Lub hauv paus tseem ceeb yog kom tau txais qhov huv thiab zoo ib yam los xyuas kom meej qhov adhesion ntawm cov txheej tiv thaiv:

Degreasing tshem tawm cov roj stains saum npoo los tiv thaiv qhov tsis sib xws hauv zos corrosion.

Descaling txhim kho lub zog sib txuas ntawm cov txheej thiab cov matrix.

Annealing tshem tawm cov kev ntxhov siab sab hauv los ntawm kev ua haujlwm tawv kom tsis txhob muaj qhov sib txawv ntau dhau ntawm tus nqi corrosion.

 

(II) Coating Protective Coating and Pattern Scribing

Lub strippable tiv thaiv txheej yog siv rau ntawm qhov chaw ntawm lub workpiece thiab kho kom tsim tau ib zaj duab xis. Cov txheej hauv cheeb tsam yuav tsum tau ua tiav yog tev tawm los ntawm cov qauv scribing lossis photosensitive thev naus laus zis kom ua tiav cov ntsiab lus meej ntawm cheeb tsam corrosion. Automated txheej thiab laser scribing tuaj yeem txhim kho cov txheej txheem sib xws thiab kev sau ntawv raug.

 

(III) Tshuaj Milling

Lub workpiece yog dai thiab raus rau hauv HF-HNO₃ hom tov kua qaub milling tov. Kev tshem tawm cov khoom ntau yog pom tau los ntawm kev tswj cov concentration, kub, nplawm nrawm thiab lub sijhawm corrosion.

Additives xws li sodium dodecyl sulfate (kom tiv thaiv corrosion grooves thiab ripples), urea thiab ethylene glycol n-butyl ether ntxiv. Cov txheej txheem tsis yog nruj me ntsis tswj los tiv thaiv acid volatilization thiab txheej tsis ua hauj lwm.

 

(IV) Tom qab-kev kho mob thiab kev soj ntsuam zoo

Tom qab corrosion, peb yuav tsum tau ntxuav lub workpiece nrog dej kom tshem tawm cov residual acid thiab tev tawm lub txheej.Tom qab ntawd, qhov seem soj ntsuam, nto roughness kuaj thiab hydrogen cov ntsiab lus tsom xam yog ua raws li nyob rau hauv ib theem zuj zus. Secondary milling los yog mechanical vibration kev kho mob yog ua nyob rau ntawm ntug kev nyuaj siab concentration teeb meem kom sib npaug precision thiab cov qauv kev ntseeg tau.

(I) Lub luag haujlwm txiav txim siab ntawm Lub Xeev Cov Khoom Siv

Ntau hom titanium alloys muaj cov theem sib txawv thiab kev ua haujlwm corrosion. Feem ntau, qhov siab dua cov ntsiab lus theem, qhov ceev ntawm corrosion. Qhov saum npoo ntawm forged los yog dov workpieces yog ntom, uas ua rau qis roughness tom qab milling. Cam khwb cia workpieces yuav tsum tau hloov kho ntawm corrosion tsis. Txoj kev loj hlob ntawm cov titanium alloys tshiab yuav tsum tau ua kom zoo ib txhij rau kev ua kom zoo ntawm cov tshuaj milling thiab cov txheej txheem tsis ua haujlwm kom haum rau lawv cov tshuaj tshwj xeeb.

 

(II) Lub Cev Muaj Zog ntawm Milling Solution Performance

HF dominates tus nqi corrosion thiab HNO₃ tswj qhov roughness nto. Lub ntim piv ntawm 2: 1 ~ 3: 1 ntawm ob tuaj yeem sib npaug tus nqi corrosion thiab nto zoo. Peb kuj tuaj yeem kho qhov sib piv raws li xav tau. Thaum lub sij hawm ua, cov concentration ntawm titanium ions nyob rau hauv cov tshuaj yuav nce, yog li nws yog tsim nyog los ntxiv los yog hloov cov kev daws teeb meem kom muaj kev ua tau zoo thiab xyuas kom meej milling sib xws.

 

(III) Guarantee Lub luag haujlwm ntawm Cov Khoom Siv Ua Haujlwm

Cov cuab yeej tshwj xeeb milling yuav tsum muaj kev tswj qhov kub thiab txias, nplawm kom zoo thiab corrosion-cov qauv tiv thaiv. Cov khoom siv rau kev ua cov khoom loj yog nruab nrog cov khoom siv dai yooj yim. Cov cuab yeej ntse saib xyuas cov txheej txheem tsis nyob hauv lub sijhawm dhau los ntawm cov sensors thiab hloov kho kom txo tau cov kev cuam tshuam ntawm phau ntawv thiab tib neeg yuam kev, txhim kho machining precision thiab efficiency.

 

 

Cov ntawv thov tseem ceeb ntawm titanium alloy tshuaj milling yog aerospace. Nws tuaj yeem paub txog kev ua haujlwm hnyav ntawm cov nyias nyias -cov khoom siv phab ntsa xws li cov dav hlau tis thiab cov fuselage panels. Nws kuj tuaj yeem txo qhov hnyav thiab txhim kho kev ua haujlwm thaum ua kom muaj zog ntawm cov qauv.

Nws kuj yog tsim rau machining complex qhov chaw xws li aero- cav casings thiab hniav, ua tau raws li qhov yuav tsum tau precision ntawm siab - kub thiab siab - ceev ua hauj lwm tej yam kev mob.

 

Cov txheej txheem no tseem tuaj yeem siv rau kev tsim khoom ntawm titanium alloy ntxeem tau qhov chaw thiab cov khoom siv micromechanical, nrog rau kev kho deg ntawm forgings thiab castings.
