1. Tshuaj muaj pes tsawg leeg & Purity
Qhov tseem ceeb sib txawv yog nyob rau hauv qhov siab tshaj plaws ntawm cov ntsiab lus ntawm interstitial ntsiab (oxygen, nitrogen, hydrogen, carbon, hlau).
Qib 1: Muaj qib impurity qis tshaj ntawm CP titanium qib. Nws yog qhov ntshiab tshaj plaws, nrog kev tswj nruj dua ntawm oxygen thiab hlau.
Qib 2: Muaj cov pa oxygen thiab hlau me ntsis siab dua piv rau Qib 1. Qhov kev nce me me ntawm cov impurities no yog lub luag haujlwm rau nws lub zog ntau dua.
2.Mechanical Properties
Hais txog cov khoom siv kho tshuab, Qib 1 muaj qhov qis tensile thiab lub zog tawm los, nrog lub zog tensile yam tsawg kawg nkaus ntawm 240 MPa (35 ksi) thiab lub zog tsawg kawg nkaus ntawm 170 MPa (25 ksi). Txawm li cas los xij, nws muaj qhov siab tshaj plaws ductility thiab formability ntawm tag nrho cov qib CP titanium, ua rau nws tsis tshua muaj tsim nyog rau cov txheej txheem txias heev. Qib 2, ntawm qhov tod tes, muaj lub zog loj dua, nrog lub zog tensile yam tsawg kawg nkaus ntawm 345 MPa (50 ksi) thiab qhov tsawg kawg nkaus lub zog ntawm 275 MPa (40 ksi), thaum tseem tuav tau zoo ductility, txawm tias nws formability qis dua qib 1, thiab nws hardness kuj siab dua qib 1.
3. Corrosion Resistance
Cov qib ob muaj qhov zoo heev thiab sib piv corrosion kuj nyob rau hauv feem ntau ib puag ncig, xws li seawater, oxidizing acids, thiab chlorides. Txij li thaum lawv yog ob qho tib si unalloyed titanium, lawv passive oxide txheej muab kev tiv thaiv zoo dua, thiab qhov sib txawv me me ntawm purity tsis tsim qhov sib txawv hauv kev ua haujlwm corrosion rau cov qauv siv.
4. Weldability
Ob qib yog nkag tau yooj yim weldable siv cov txheej txheem txheej txheem (GTAW / TIG, thiab lwm yam) nrog rau cov roj inert shielding.
Qib 1 feem ntau nyiam ua cov hlau muab tub lim rau vuam Qib 2 lossis lwm yam titanium alloys vim nws cov ductility siab heev, uas pab txo qis kev pheej hmoo ntawm kev sib tsoo.
Qib 2 kuj yog weldable thiab feem ntau welded rau nws tus kheej siv Qib 1 lossis Qib 2 muab tub lim.
5. Cov ntawv thov ib txwm
Qhov kev xaiv ntawm ob yog tsav los ntawm qhov yuav tsum tau muaj zog thiab formability:
Qib 1: Siv rau cov ntawv thov uas xav tau qhov siab tshaj plaws formability thiab ductility qhov twg yuav tsum muaj zog tsawg. Piv txwv suav nrog qhov sib sib zog nqus- kos qhov chaw, cov khoom siv hluav taws xob sib hloov, cov raj condenser, thiab cov vaj huam sib luag vaj tse.
Qib 2: Cov "ua haujlwm" ntawm CP titanium. Nws muaj qhov zoo sib npaug ntawm formability, lub zog, thiab tus nqi. Nws yog qib siv dav tshaj plaws rau kev siv dav dav -cov phiaj xwm siv xws li cov kav dej, cov li qub, cov khoom siv hauv hiav txwv, cov khoom siv tshuaj lom neeg, thiab cov khoom siv dav hlau.
Hauv cov ntsiab lus, Qib 1 yog qhov purest, softest, thiab feem ntau formable, thaum Qib 2 muaj zog dua thiab feem ntau siv rau kev siv hauv kev lag luam.
