Yuav Ua Li Cas Xaiv Ntawm Qib 2 thiab Qib 4 Titanium?

                                                                                                 

 

Qib 2 thiab Qib 4 titanium yog cov khoom lag luam ntshiab titanium.

 

Qib 2 titanium(Gr2) thiab Qib 4 titanium (Gr4) ob leeg yog cov khoom lag luam ntshiab titanium (CP titanium) series. Txawm hais tias ob qho tib si hu ua titanium ntshiab, qhov sib txawv ntawm cov ntsiab lus hauv cov ntsiab lus muab lawv cov yam ntxwv sib txawv.

 

Gr2: Kev lag luam ntshiab titanium nrog kev ua tau zoo thiab kev ua haujlwm zoo.

Gr4: Siab hardness, lub zog, thiab hnav tsis kam. Qhov sib txawv ntawm cov tshuaj muaj pes tsawg leeg thiab lawv qhov cuam tshuam rau kev ua tau zoo

 

Qhov sib txawv tseem ceeb ntawm Gr2 thiab Gr4 nyob hauv lawv cov pa oxygen thiab cov ntsiab lus hlau. Oxygen plays lub luag haujlwm ntxiv dag zog hauv titanium; cov pa oxygen ntau dua ua rau muaj zog dua thiab tawv, tab sis qis dua ductility.

lus	Gr 2	Gr4
titanium	tshuav nyiaj li cas	tshuav nyiaj li cas
Cov pa oxygen (O)	Tsawg dua lossis sib npaug li 0.25%	Tsawg dua lossis sib npaug li 0.40%
Hlau (Fe)	Tsawg dua lossis sib npaug li 0.30%	Tsawg dua lossis sib npaug li 0.50%
Nitrogen (N)	Tsawg dua lossis sib npaug li 0.03%	Tsawg dua lossis sib npaug li 0.05%
Hydrogen (H)	Tsawg dua lossis sib npaug li 0.015%	Tsawg dua lossis sib npaug li 0.015%

Ntawm cov khoom siv tshuaj, cov ntsiab lus oxygen muaj qhov cuam tshuam loj tshaj plaws rau kev ua haujlwm. Nrog nce oxygen cov ntsiab lus, tensile lub zog thiab tawm los lub zog nce me ntsis. Qhov no yog vim li cas GR4 muaj zog dua thiab nyuaj dua GR2, txawm tias ob qho tib si hu ua lag luam ntshiab titanium.

 

Nyob rau hauv ntau yam, GR4 yog qhov tseeb version ntawm ntshiab titanium, tsis yog ib qho yooj yim alloy.

Mechanical Properties Sib piv

kev ua tau zoo	Gr 2	Gr4
tensile zog	Kwv yees li 345 MPa	Kwv yees li 550 MPa
Yield zog	Kwv yees li 345 MPa	Kwv yees li 550 MPa

Qib 4 titanium muaj zog dua thiab hardness dua qib 2 titanium. Txawm li cas los xij, Qib 2 titanium yooj yim dua rau kev ua haujlwm thiab muaj qhov yooj yim dua.

Qib 4 titanium muaj zog dua qib 2 titanium vim nws muaj cov ntsiab lus ntau dua ntawm cov kab mob xws li oxygen. Cov ntsiab lus no ua rau cov qauv siv lead ua sab hauv ntawm titanium hlau ntau dua, tawm hauv chav tsawg rau kev txav mus los, yog li ua kom nws lub zog thiab hardness. Txawm li cas los xij, nws nyuaj dua rau kev ua haujlwm.

Formability thiab Machining yam ntxwv

Gr2: Cov txheej txheem yooj yim dua, kev ua haujlwm txias txias, tsim nyog rau kev ua cov geometry nyuaj.

Gr4: Lub zog siab dua, zoo dua hnav tsis kam, tab sis yuav tsum muaj ntau dua rau kev ua, thiab muaj qhov qis dua me ntsis.

Corrosion Resistance thiab Biocompatibility

* Ob qho khoom siv tau zoo heev corrosion kuj, haum rau seawater, chloride, thiab acidic ib puag ncig.

* Dawb ntawm alloying ntsiab xws li txhuas thiab vanadium, yog li ntawd muaj zoo biocompatibility, haum rau kev kho mob thiab kev sib cuag daim ntaub ntawv.

Gr4: High hardness, zoo hnav tsis kam, thiab muaj zog nto durability.

Gr2: Mos kev ntxhib los mos thiab zoo heev ductility.

Kev pom zoo xaiv:

Xaiv cov khoom tsim nyog raws li qhov chaw thov tshwj xeeb, qhov chaw, thiab keeb kwm yav dhau. Rau siab zog thiab corrosion kuj, xaiv GR4. Txhawm rau ua kom yooj yim, ua qhov tseem ceeb GR2.

Hauv cov ntsiab lus

qib	Cov yam ntxwv tseem ceeb
Gr 2	Optimal operability thiab balanced kev ua tau zoo
Gr4	Lub zog siab tshaj plaws thiab zoo heev hnav tsis kam

bOb ob leeg khaws cov txiaj ntsig tseem ceeb ntawm kev lag luam ntshiab titanium: tsawg ntom ntom, muaj zog corrosion kuj, thiab zoo biocompatibility. Qhov kev xaiv kawg yog nyob ntawm koj daim ntawv thov yuav tsum tau: yooj yim ntawm kev ua vs. mechanical zog thiab hnav tsis kam.
