Daim Ntawv Qhia Kev Xaiv Rau Titanium Qib 2

Gr2 (CP Ti)tau dhau los ua cov khoom siv dav tshaj plaws hauv siab -kawg teb vim nws qhov kev sib npaug, kev ua haujlwm zoo, thiab tus nqi-effectiveness.Muaj ntau qib titanium alloy, yuav ua li cas txiav txim siab seb Gr2 ua tau raws li qhov yuav tsum tau ua thiab tsis txhob poob rau hauv kev nkag siab yuam kev?

 

I. Core Performanceua gr2

Corrosion Resistance: Nws tuaj yeem tsim qhov ntom ntom, nws tus kheej- kho titanium oxide zaj duab xis rau saum npoo. Nws muaj kev tiv thaiv corrosion zoo dua, dav siv hauv marine engineering (pipes, connectors) thiab chemical engineering (reactor liners, transmission pipelines).

 

Mechanical PropertiesLub zog tensile yog 370-480MPa. Lub zog tawm los yog 275MPa, thiab elongation yog 20% ​​-25%. Txawm hais tias nws lub zog qis dua li ntawm Gr5, nws muaj qhov toughness zoo heev. Nws yog tsim rau kev kho hniav implant abutments (cov kabmob occlusal quab yuam + yas ua) thiab cov khoom siv hluav taws xob (ua haujlwm rau thermal stress cracking).

 

Biocompatibility thiab Thermal Conductivity: nws tsis muaj teeb meem cov ntsiab lus thiab muaj biocompatibility zoo heev thiab nws yog haum rau orthopedic implants thiab kho hniav. Nrog lub thermal conductivity ntawm 16.3W / (m·K), nws tuaj yeem ua tau raws li qhov xav tau ntawm thermal rwb thaiv tsev ntawm aerospace thiab lwm qhov chaw.

 

II. Kev Siv Tshuab

1. txheej txheem forging

Lub forging kub ntawm Gr2 yog 800-950℃.Nws yuav tsum tau kub tswj kom tsis txhob grain coarsening. Forging tuaj yeem kho cov nplej, txhim kho qhov ntom ntom, thiab txhim kho qhov sib xws ntawm cov khoom siv kho tshuab, ua rau nws tsim nyog rau txoj kev forgings xws li valve cores. Tom qab forging, kev ntxhov siab annealing yog ua los ntawm kev tuav ntawm 600-700℃tom qab cua txias kom tshem tawm kev ntxhov siab thiab rov ua kom zoo dua qub.

 

2. Vuam txheej txheem

Gr2 muaj weldability zoo thiab tuaj yeem welded siv txoj kev xws li TIG thiab MIG. Vuam yuav tsum tau siv cov roj argon nrog ib tug purity ntawm ntau dua los yog sib npaug rau 99.99% kev tiv thaiv los tiv thaiv titanium los ntawm reacting ntawm kub kub los ua nkig tebchaw. Kev ntxhov siab nyem annealing yog pom zoo tom qab vuam kom txo qis kev ntxhov siab thiab tiv thaiv kev tawg.

 

3. Kev txiav thiab tsim cov txheej txheem

Gr2 muaj kev txiav nyuaj me ntsis. Vim nws cov thermal conductivity tsis zoo, cov cuab yeej cemented carbide yuav tsum raug xaiv, nrog rau kev txiav ceev, tus nqi pub loj, thiab cov dej txias txaus. Nws cov plasticity siab ua rau nws haum rau kev ua haujlwm txias xws li stamping thiab dabtsi yog khoov yam tsis muaj preheating complex, txo cov nqi.

III. Kev sib piv ntawm Gr2 thiab Gr5

Gr5 (Ti-6Al-4V), raws li cov titanium alloy feem ntau siv, muaj zog ntau dua li Gr2 thiab feem ntau siv nyob rau hauv high-end teb xws li aerospace. Txawm li cas los xij, hauv ntau qhov xwm txheej, qhov tshwj xeeb zoo ntawm Gr2 ua rau nws xaiv zoo dua.

 

Kev sib piv	Gr2 (CP Ti)	Gr5 (Ti-6Al-4V)
Nqi Advantage	Tus nqi siab dua -kev ua tau zoo, cov nqi khoom siv yog 1/2 ~ 2/3 ntawm Gr5, txhim kho cov khoom lag luam kev sib tw zoo	Muaj aluminium thiab vanadium alloying ntsiab lus, complex smelting thiab ua cov txheej txheem, tus nqi yog 1.5 ~ 2 npaug ntawm Gr2
Kev ua haujlwm nyuaj	Tsawg zog thiab siab plasticity, yooj yim txiav / vuam / txias txheej txheem; Lub neej ntev lub cuab yeej, cov khoom siv qis qis thiab ua tiav	Lub zog siab thiab hardness, cov cuab yeej hnyav hnav thaum txiav, kev tswj nruj ntawm vuam tsis, preheating yuav tsum tau ua kom txias, ua haujlwm ntev thiab tus nqi siab
Corrosion Resistance thiab Biocompatibility	1. Ntau ruaj khov nyob rau hauv xov xwm xws li dilute sulfuric acid thiab ntub chlorine; 2. Ntshiab titanium muaj pes tsawg leeg, txhim khu kev qha biocompatibility	1. Zoo corrosion kuj, tab sis alloying ntsiab yuav txo tau corrosion kuj nyob rau hauv tej ib puag ncig; 2. Muaj cov ntsiab lus vanadium, uas tej zaum yuav muaj feem cuam tshuam rau qee tus tib neeg lub cev
Tsawg-Kev Ua Haujlwm Kub	Tsis muaj qhov txo qis hauv plasticity thiab toughness ntawm cov kua nitrogen kub (-196 degree), ruaj khov khoom	Tej zaum yuav muaj kev nce brittleness nyob rau hauv qis -kub ib puag ncig
Siv tau Scenarios	Cov kav dej tshuaj, cov cuab yeej siv kho mob pej xeem, kev cog lus kho mob (kev cog hniav, cog me me orthopedic), qis- cov cuab yeej cia kub, tub yees engineering	Muaj cov qauv tsim cov khoom uas xav tau lub zog siab, cov khoom siv hauv aerospace, hnyav -cov khoom siv tshuab ua haujlwm, thiab lwm yam.

 

IV. Zam kev xaiv yuam kev

Qhov muag tsis pom kev nrhiav lub zog siab: Hauv cov xwm txheej uas tsis tas yuav tsum muaj lub zog siab heev (xws li cov hlab ntsha thiab cov khoom noj khoom haus 1. khoom), lub zog ntawm Gr2 txaus. Xaiv cov qib siab - lub zog xws li Gr5 yuav ua rau tus nqi nce, nce kev ua haujlwm nyuaj, thiab ua rau khib nyiab.

 

2.Tsis quav ntsej qhov sib txuam ntawm kev ua thiab cov khoom siv: Gr5 muaj kev ua haujlwm txias txias tsis zoo, thiab xaiv nws rau txoj haujlwm stamping thiab welded qhov chaw yog qhov ua rau tawg. Gr2 muaj cov yas zoo, haum rau ntau yam kev ua haujlwm txias thiab vuam txheej txheem, thiab tsim nyog rau kev ua haujlwm nyuaj.

 

3. PaubGr2 li "Txhua-Lub Hom Phiaj" hauv Corrosion Resistance: Gr2 tsuas yog haum rau cov pa corrosive ib puag ncig thiab tsis tuaj yeem siv rau hauv cov xwm txheej corrosive heev, xws li concentrated nitric acid thiab hydrofluoric acid. Rau ib puag ncig hnyav, tshwj xeeb corrosion- qib tiv taus xws li Gr7 thiab Gr12 yuav tsum raug xaiv.

 

4.Tsis saib xyuas qhov sib npaug ntawm tus nqi thiab kev ua haujlwm: Rau tus nqi, Gr5 ntau dua Gr2. Kev xaiv yuav tsum sib npaug cov kev xav tau thiab tus nqi - ua tau zoo. Hauv cov xwm txheej xws li cov cuab yeej siv kho mob pej xeem, qhov ua tau zoo thiab tus nqi zoo ntawm Gr2 txaus los ua kom tau raws li qhov xav tau, thiab tsis tas yuav xaiv cov qib siab - nqi.
