Kev cuam tshuam ntawm titanium ntsia hlau hardness thiab nws cov yam ntxwv cuam tshuam

Titanium screws yog cov khoom sib txuam hauv aerospace, tsheb, khoom siv kho mob thiab lwm yam lag luam. Hardness yog ib qho tseem ceeb uas yuav tsum tau xav txog thaum xaiv cov khoom siv ntsia hlau. Lub hardness ntawm titanium screws nyob ntawm ntau yam, nrog rau qhov tsis muaj qhov tsis xws luag, cov khoom siv hlau, kev kho cua sov thiab kev ua haujlwm. Kab lus no tham txog yam uas cuam tshuam rau qhov hardness ntawm titanium screws.

Lub hardness ntawm titanium screws feem ntau yog muab los ntawm Vickers hardness los yog Rockwell hardness. Lub hardness ntawm titanium screws yog tsawg, feem ntau ntawm 120-160HV. Thaum ntsuas, qhov hardness ntawm steel screws feem ntau yog nyob nruab nrab ntawm 300-500HV. Txawm hais tias titanium screws tsis tshua muaj zog, lawv muaj lwm yam khoom zoo xws li nyias thickness, siab zog, tsis kam mus rau disintegration, thiab lwm yam., ua rau lawv haum rau ntau yam kev siv.

kev huv
Titanium cov ntaub ntawv nrog purity siab dua feem ntau muaj qis hardness. Ntshiabtitanium screwstsis tshua muaj zog thiab tawv vim lawv deform thiab soften ntau yam tsis muaj teeb meem. Txawm li cas los xij, hauv qee qhov kev siv tau zoo, xws li aerospace, lub teeb yuag thiab kev siv rub yog qhov tseem ceeb tshaj qhov muaj zog thiab tawv.

Alloying
Cov khoom xyaw sib txawv xws li txhuas, vanadium, thiab zirconium tuaj yeem muab ntxiv rau titanium kom nws cov tawv tawv. Ntxiv cov khoom xyaw alloying tuaj yeem hloov titanium lub pob zeb tsim thiab cov khoom tsis muaj zog, yog li ua kom tawv tawv. Piv txwv li, cov ntsia hlau ua los ntawm titanium alloy $Ti-6Al-4V$ muaj zog thiab tawv, tab sis lawv tuaj yeem tiv taus kev sib tw ntau.

Kev kho cua sov
Kev kho cua sov tuaj yeem hloov cov qauv siv lead ua ntawm titanium screws, cuam tshuam rau lawv cov hardness thiab lub zog. Kev kho cua sov feem ntau suav nrog kev kho tshuaj thiab kev kho kev laus. Cov txheej txheem suav nrog cua sov cov khoom siv titanium rau cov phiaj xwm kev sib tw kub thiab tom qab ntawd txias sai sai tom qab lub sijhawm ua haujlwm nyuaj thiab lub zog. Tom qab kev kho mob nruj heev, cov txheej txheem maturation yuav tsum tau muab cov khoom xa rov qab mus rau qhov ntsuas kub thiab khaws cia rau lub sijhawm kom txuas ntxiv hloov lub pob zeb tsim thiab hardness.

Kev siv tshuab
Kuj cuam tshuam qhov hardness ntawm titanium screws. Kev ua thiab kev loj hlob ntawm titanium screws integrates txias ua thiab kub ua. Feem ntau, kev ua haujlwm txias muaj cov txheej txheem xws li kev kos duab kab mob thiab txias dov, uas tuaj yeem ua rau titanium screws muaj zog thiab nyuaj. Lub hardness ntawm titanium screws yog cuam tshuam los ntawm kev kho cua sov, uas muaj xws li cua sov tso tawm thiab kub dov.

Nyob rau hauv luv luv, muaj ntau yam uas cuam tshuam rau hardness ntawm titanium screws, nrog rau zoo, alloy muaj pes tsawg leeg, kev kho cua sov thiab kev nrhav. Cov khoom ua los ntawm purer titanium feem ntau muaj qis hardness.
