TC4 titanium alloy machining txheej txheem cov ntsiab lus

TC4 titanium alloy, raws li cov khoom siv hlau nrog kev ua tau zoo, tau siv dav hauv ntau qhov chaw xws li aerospace, biomedical, tshuaj thiab tsheb tsim vim nws lub zog siab, tsis tshua muaj siab, zoo heev corrosion kuj thiab cov txheej txheem zoo plasticity. Kev sib txawv thiab qhov nyuaj ntawm nws cov txheej txheem tsis tsuas yog qhia txog kev nce qib ntawm cov khoom siv science, tab sis kuj ua tau raws li cov kev xav tau ntawm kev lag luam sib txawv rau cov ntaub ntawv ua tau zoo. Hauv qab no, peb yuav txheeb xyuas cov txheej txheem machining ntawm TC4 titanium alloy kom meej.
I. Kev Npaj Khoom
Hauv kev ua ntawm TC4 titanium alloy, kev npaj cov khoom yog thawj kauj ruam. Vim hais tias titanium alloy yog rhiab heev rau cua sov thiab yooj yim rau rebound, annealing feem ntau yuav tsum tau ua ua ntej ua kom txo tau cov hardness, txhim kho plasticity, thiab txo cov kev ntxhov siab concentration nyob rau hauv cov ua. Nyob rau tib lub sijhawm, xyuas kom meej tias cov khoom saum npoo yog huv si thiab tsis muaj impurities kom tsis txhob muaj kab mob thiab cov cuab yeej hnav thaum lub sij hawm machining. Xaiv cov cuab yeej txiav txoj cai, xws li carbide, ceramic lossis cubic boron nitride cov cuab yeej, yog qhov tseem ceeb rau kev txhim kho machining efficiency thiab xyuas kom zoo machining.
Thib ob, txiav kev ua haujlwm
Kev txiav yog qhov txuas txuas ntawm TC4 titanium alloy ua. Vim lub siab hardness thiab zoo thermal conductivity ntawm titanium alloy, ib tug loj npaum li cas ntawm tshav kub yuav generated thaum lub sij hawm txiav, uas yuav yooj yim ua rau lub deformation ntawm lub workpiece thiab cov cuab yeej hnav. Yog li ntawd, nyob rau hauv cov txheej txheem txiav, ib tug series ntawm kev ntsuas yuav tsum tau coj mus rau txo qhov kub thiab txias thiab txhim kho lub machining raug. Piv txwv li, kev siv cov cuab yeej siv high-speed txiav, los ntawm kev ua kom cov txiav ceev kom txo tau lub sij hawm txiav, yog li txo qhov kub ntawm qhov txiav; kev siv cov dej txias txias kom tsis txhob overheating ntawm lub workpiece; kev siv cov cuab yeej ntsuas precision rau kev saib xyuas lub sijhawm tiag tiag ntawm lub tshuab machining qhov ntev kom ntseeg tau tias qhov tseeb machining ua tau raws li qhov yuav tsum tau ua.

III. Kev kho cua sov
Kev kho cua sov yog ib qho tseem ceeb ntawm TC4 titanium alloy ua. Los ntawm annealing, tshuaj kho thiab kev laus kev kho mob thiab lwm txoj kev kho cua sov, tuaj yeem txhim kho cov khoom ntawm titanium alloy, txhim kho nws lub zog, hardness thiab corrosion kuj. Annealing kev kho mob tuaj yeem tshem tawm qhov kev ntxhov siab thaum ua tiav, txhim kho cov yas thiab tawv ntawm cov khoom; Kev kho cov khoom siv tuaj yeem ua rau cov khoom sib xyaw ua ke sib faib, txhim kho lub zog thiab hardness ntawm cov khoom; Kev laus kev kho mob tuaj yeem ua kom ruaj khov rau lub koom haum thiab cov khoom ntawm cov khoom. Nyob rau hauv cov txheej txheem kev kho cua sov, cov cua kub kub, tuav lub sij hawm thiab txias npaum li cas thiab lwm yam yuav tsum tau nruj me ntsis tswj kom ntseeg tau tias cov cua sov nyhuv yog pom zoo.
Kev kho saum npoo
TC4 titanium alloy nto kev kho mob kuj yog ib qho tseem ceeb ntawm kev txhim kho nws cov kev ua tau zoo. Kev txhaj tshuaj peening tuaj yeem txhim kho lub zog qaug zog ntawm titanium alloy qhov chaw, los ntawm kev tsim cov txheej txheem kev ntxhov siab rau ntawm qhov chaw los tiv thaiv kev nthuav dav ntawm kev qaug zog tawg. Plasma spraying los yog explosion spraying tshuab tuaj yeem tsim cov txheej txheej hnav-tiv taus ntawm qhov chaw los txhim kho qhov hnav tsis kam thiab kev pabcuam lub neej ntawm cov khoom. Kev kho anodic oxidation tuaj yeem tsim cov yeeb yaj kiab oxide ntom ntom ntawm titanium alloy los txhim kho corrosion thiab hardness ntawm cov khoom. Tsis tas li ntawd, electroplating, micro-arc oxidation thiab low-pressure nqus nitriding kev kho mob thiab lwm yam txheej txheem kho deg kuj tau siv dav hauv kev ua ntawm TC4 titanium alloy.
Txhawm rau kom ua tiav, cov txheej txheem machining ntawm TC4 titanium alloy npog ntau yam kev sib txuas xws li kev npaj khoom, txiav, kev kho cua sov thiab kev kho deg. Txhua qhov txuas yuav tsum nruj me ntsis tswj cov txheej txheem tsis tu ncua thiab cov txheej txheem kev ua haujlwm kom ntseeg tau tias cov khoom tiav ua tau raws li cov qauv tsim thiab siv kev ua haujlwm. Nrog rau kev nce qib ntawm kev tshawb fawb thiab thev naus laus zis thiab kev ua kom zoo dua qub ntawm cov txheej txheem, cov txheej txheem machining ntawm TC4 titanium alloy tseem yuav raug txhim kho thiab hloov kho dua tshiab, muab cov ntaub ntawv zoo dua rau kev siv hauv ntau thaj chaw.
