Kev soj ntsuam ntawm cov yam ntxwv, kev faib tawm thiab machining tshuab ntawm titanium alloys

Nyob rau hauv chav tsev kub, titanium alloys tuaj yeem faib rau hauv peb pawg loj raws li lawv cov qauv matrix:

• Titanium alloys (cov qib sawv cev TA3 series)

Crystal qauv: hexagonal kaw-ntim lus Lattice theem

Cov txiaj ntsig: Zoo heev High-kub ruaj khov (ntev ua haujlwm ntawm 500 degree), muaj zog oxidation tsis kam

Cov yam ntxwv ua: Tsis tuaj yeem kho cua sov, kuj muaj lub zog tsawg ntawm chav tsev kub, kev ua haujlwm zoo tshaj plaws

Qeb qeb: Ta7, Ta8, thiab lwm yam.

• titanium alloys (muaj cov qib kev TB6 series)

Crystal Qauv: Lub Cev Nruab Nrab Sau Cov Khaub Ncaws Plaub Lattic Lattice

Cov txiaj ntsig zoo: Cov khoom tawg zoo heev deformation plastity, tshav kub-kho kom sov

Kev txwv: Tsis zoo thermal stability (<300°C), most difficult cutting

Qeb qeb: TB1, TB2, thiab lwm yam.

• + duplex titanium alloys (cov qib sawv cev TC4 Series)

Crystal qauv: \/ Ob Tus Qauv Composseite

Kev Ua Tau Zoo: Sib Xws Siab Siab \/ Qub-Qhov Kub-Qhov Kub Siab, Yas thiab Kev Lom Zem

Cov yam ntxwv ua: Cov kev ua cua sov-kho kom sov, nruab nrab txiav nyuaj

Qeb qeb: TC1, TC4, thiab lwm yam.

• Cov Neeg Mob Thermodynamic

Conductivity tsuas yog 1 \/ 6-1} \/ 7 ntawm 45 hlau, thiab cov chaw txiav kub tuaj yeem mus txog {}}} degree

Titanium chips yog nquag rau tus kheej-impition thaum kub (ignition point txog 600 degree)

• Neeg Kho Tshuab

Elastic modulus yog 110 GPA (50% ntawm 45 hlau), ua rau muaj kev tawm tsam tseem ceeb

Ua Hardening Index yog qhov siab li 0. 4, saum npoo hat {3}}%

• Cov Kab Mob Siv Tshuaj

Muaj kev sib xws nrog coated titanium cuab yeej, exacerbated nplaum hnav

Yooj yim reacts nrog O \/ N ntawm qhov kub siab los ua cov tawv me me txheej (tuab {{μm)

Tiv tauj ntev ntawm lub cuab yeej thiab cHips tsuas yog 1\/3 ntawm cov tshuaj carbon hlau, nrog kev ntxhov siab hauv zos

Txiav kev sib zog hloov kho amazitude mus txog 20-30%, cuab tam chapping tus nqi nce

• Cov khoom siv xaiv

Nyuaj alloys: nyiam xaiv k-hom (YG series) tsis muaj ti matrix

Cov Cuab Yeej Loj: PCB tuam txhab lub neej tuaj yeem nce los ntawm 3-5 lub sij hawm

• Cov duab ntsuas ntsuas parameter

Sua teb {{{{0}}}}} degree, {}}. 1 hli

Siv ob lub kaum sab xis (lub ntsiab rum lub kaum sab xis 45 degree + sab ob kaum lub kaum sab xis 15 degree)

• Txiav Ceev Control

Tig: 50-120 m \/ min

MILLING: {30-80 m \/ min

DRILLING: 10-30 m \/ min

• Cov txheej txheem cua txias

High-siab sab hauv txias (siab> 7 MPA)

Roj-Raws Li Cov Khaub Ncaws Cua Txias (muaj cov chlorine \/ sulfur siab siab additives)
