Lub cev muaj zog ntawm titanium
Apr 07, 2026| Titanium muaj ib tug txheeb ze ntom ntawm 4.506, ib tug melting point ntawm 1668 degree, thiab ib tug boiling point ntawm 3287 degree. Nws resistivity yog 42 x 10⁻⁸ Ω·m (20 degree). Vim nws cov txheej oxide tuab, nws yog corrosion-resistant. Nyob rau hauv chav tsev kub, nws tsis hnov mob nrog oxygen, halogens, los yog dej; Txawm li cas los xij, thaum kub kom liab - kub, nws reacts nrog oxygen los tsim titanium dioxide. Nws tsis cuam tshuam nrog nitric acid, dilute sulfuric acid, los yog alkalis, tab sis nws yog soluble nyob rau hauv concentrated sulfuric acid, hydrofluoric acid, thiab aqua regia.
Titanium yog malleable; siab -purity titanium tuaj yeem muaj qhov elongation ntawm 50-60% thiab txo thaj tsam ntawm 70-80%, tab sis nws lub zog tsawg, ua rau nws tsis haum raws li cov khoom siv. Lub xub ntiag ntawm impurities hauv titanium cuam tshuam rau nws cov khoom siv kho tshuab, tshwj xeeb tshaj yog cov impurities interstitial (oxygen, nitrogen, carbon), uas tuaj yeem ua rau nws lub zog thiab txo nws cov ductility. Cov khoom zoo heev ntawm titanium raws li cov khoom siv tau ua tiav los ntawm kev tswj hwm nruj ntawm cov ntsiab lus tsis huv uas tsim nyog thiab ntxiv cov ntsiab lus alloying. Titanium yog silvery-dawb, malleable hlau nrog zoo kev lag luam tseem ceeb vim nws ntau yam khoom muaj nqis. Nws yog tsawg dua li hlau, muaj zog dua li txhuas, thiab muaj corrosion kuj zoo ib yam li platinum.
Cov khoom no ua rau nws yog ib qho khoom siv zoo tshaj plaws rau kev tsim lub cav, lub dav hlau thav duab, foob pob hluav taws, thiab cov chaw hauv hiav txwv, uas xav tau lub teeb yuag, siab zog, thiab tiv taus qhov kub thiab txias hloov pauv- cov khoom uas titanium tsis sib xws. Qee yam ntawm titanium cov khoom, xws li lub zog tensile, yog txhim kho los ntawm nws lub peev xwm rau alloy nrog txhuas; Tsis tas li ntawd, qhov - hloov pauv kub ntawm aluminium-titanium alloys siab dua li ntawm cov ntshiab titanium. Titanium tseem tuaj yeem tsim cov alloys muaj txiaj ntsig nrog molybdenum, manganese, hlau, thiab lwm yam hlau.
