Hauv kev lag luam cov ntaub ntawv,titaniumthiabtitanium alloysmuaj feem cuam tshuam, tab sis lawv tsis yog tib yam. Qhov txawv tseem ceeb yogmuaj pes tsawg leeg.
1) Dab tsi "Titanium" txhais tau tias (titanium ntshiab)
Titaniumfeem ntau yog hais txogKev lag luam ntshiab titanium (CP Ti)-titanium nrog me me ntawm lwm cov khoom siv los tswj cov khoom.
Common CP qib:Qib 1, 2, 3, 4(feem ntau nrog me me txwv ntawm impurities xws li hlau, oxygen, nitrogen, carbon, hydrogen).
Yam ntxwv yam ntxwv:
Siab corrosion kuj
Zoo formability thiab weldability
Tsawg zogpiv nrog rau feem ntau titanium alloys (tshwj xeeb tshaj yog piv rau Ti-6Al-4V)
Kev lag luam nqa tawm:CP titanium raug xaiv thaumcorrosion kuj / formabilitytseem ceeb tshaj qhov siab tshaj plaws.
2) Dab tsi "Titanium Alloy" txhais tau tias (titanium + alloying ntsiab)
A titanium alloyyog titanium txhob txwm sib xyaw nrog lwm cov ntsiab lus (feem ntau aluminium, vanadium, molybdenum, tin, zirconium, thiab lwm yam) kom ua tiav lub zog siab dua, txhim kho qhov kub thiab txias, lossis kev ua haujlwm zoo.
Ib qho ntawm feem ntau alloys:Ti-6Al-4V (Qib 5)
(titanium + aluminium + vanadium)
Lwm tus muaj xws li:
Ti-6Al-2Sn-4Zr-6Mo (Ti-6242 / Qib 21)(feem ntau yog rau siab - zog thiab siab - qhov kub thiab txias)
Ti-3Al-2.5V, Ti-5Al-2.5Sn, thiab lwm yam (xaiv rau tus nqi / kev ua tau zoo lossis tshwj xeeb corrosion / kub xav tau)
Kev lag luam nqa tawm:Alloys raug xaiv kom tau txaismuaj zog duathiab/los yogkev ua tau zoo dua hauv ib puag ncig tshwj xeeb.
3) Tswv yim sib txawv
Lub zog
Titanium (CP Ti):feem ntauqis zog
Titanium alloys:feem ntaumuaj zog dua(feem ntau siab dua CP Ti)
Corrosion kuj
Ob leeg tuaj yeem tiv taus corrosion heev, tab sis kev xaiv nyob ntawm:
alloy muaj pes tsawg leeg
qhov chaw saum npoo
kub
thiab tshwj xeeb tshaj yog ib puag ncig (xws li, chlorides, crevices, deposits)
Ceev & hnyav kom zoo dua
Ob qho tib si titanium thiab titanium alloys muaj qhov zoo sib xws:
tsawg ceevvs. steel thiab nickel alloys
Yog li kev txuag hnyav muaj nyob nrog ob qho tib si - qib zog yog qhov sib txawv loj.
Kev tsim khoom thiab kev kho cua sov
CP yog titaniumfeem ntau yooj yim dua nyob rau hauv cov nqe lus ntawm kev ua tau zoo tuning (lub zog yog tswj feem ntau los ntawm qib / purity).
Cov alloystej zaum yuav xav tauKev kho cua sov thiab kev tswj xyuas nrujvim microstructure (alpha/beta phases) cuam tshuam rau cov khoom.
4) Yuav ua li cas engineers xaiv ntawm lawv
Siv txoj cai ntawm tus ntiv tes xoo:
XaivCP yog titaniumthaum lub hom phiaj tseem ceeb yog:
corrosion kuj
formability
thiab kev xav tau ntawm lub zog nruab nrab
(feem ntau hauv kev ua tshuaj, plating / acid ib puag ncig, thiab lwm yam)
Xaiv ibtitanium alloythaum lub hom phiaj tseem ceeb yog:
siab zog-rau- hnyav
qaug zog tsis kam (feem ntau)
structural lossis kev ua haujlwm xav tau
(feem ntau nyob rau hauv aerospace, siab -kev ua haujlwm qhov chaw, thiab lwm yam.)
Ib - kab lus xaus
Titanium (CP Ti)= kuj ntshiab titanium; feem ntau ntau formable thiab corrosion- tsom, tab sis qis zog.
Titanium alloy= titanium ntxiv rau alloying ntsiab; tsim los rau lub zog siab dua thiab ua kom haum rau txhua yam / thermal ua haujlwm.
Yog tias koj qhia kuv koj daim ntawv thov (piv txwv li, tshuaj cog hluav taws xob hloov hluav taws xob, dej hiav txwv, qhov chaw dav hlau, daim ntawv thov vuam), Kuv tuaj yeem pom zoo uas "hom" (CP vs alloy) feem ntau nyiam thiab vim li cas.
