Qhov ceev ntawm titanium thiab titanium alloys tsuas yog 4.51, uas yog me dua cov hlau thiab tsuas yog ib nrab ntawm qhov hnyav ntawm cov hlau, tab sis nws lub zog zoo ib yam li cov pa roj carbon zoo tib yam. Titanium yog cov hlau uas muaj zog heev uas yog thermodynamically tsis ruaj khov. Nrog cua, titanium hlau tuaj yeem tsim cov txheej txheem oxide (titanium dioxide). Cov txheej no ruaj khov, muaj zog adhesion, thiab tshwj xeeb tshaj yog tiv thaiv oxide zaj duab xis txiav txim siab corrosion kuj ntawm titanium. , yog li ntawd titanium muaj corrosion kuj zoo heev, ua raws li lub teeb kev ntxhib los mos, siab tensile zog, thiab zoo txhua yam khoom yog lwm yam zoo heev ntawm titanium alloys.
titanium alloys tuaj yeem muab faib ua corrosion-resistant titanium alloys, cov qauv titanium alloys, kub-resistant titanium alloys, thiab qis-kub titanium alloys raws li lawv siv.
1. tuaj yeem paub qhov txawv ntawm cov xim. Titanium yog tsaus me ntsis, nthuav tawm cov xim txias, uas xav tias txias, thiab titanium yog me ntsis tsaus dua li cov hlau. Cov hlau yog dawb, xim daj. Ob xim pom meej.
2. Cov txheej txheem tshuaj, xws li soaking hauv nitric acid, tuaj yeem siv los ua kom sib txawv thiab. Titanium tsis hnov mob, thiab stainless hlau reacts hnyav thaum nws muab tso. Tej zaum nws yuav nyuaj rau qhia qhov txawv ntawm cov ntshiab titanium thiab titanium alloys los ntawm sab nrauv.
3. Titanium tuaj yeem kos cov cim grey-dub ntawm cov vuas ceramic, tab sis stainless hlau tsis tuaj yeem.
4. Titanium muaj corrosion kuj zoo: ib tug ntom oxide zaj duab xis yog ib qho yooj yim tsim rau saum npoo ntawm titanium alloy hauv qab 550 degree, yog li nws tsis yooj yim rau oxidized ntxiv, thiab muaj kev tiv thaiv siab rau huab cua, dej hiav txwv, chav, thiab qee qhov. acids, alkalis, thiab soft media. Anti-lossis yam.
5. Titanium muaj thermal zog zoo: lub melting point ntawm titanium alloy yog 1660 degree, uas yog siab tshaj ntawm cov hlau, thiab muaj thermal zog. Nws tuaj yeem ua haujlwm qis dua 550 degree thiab pom zoo toughness ntawm qhov kub thiab txias.
6. Titanium yog qhov nyuaj rau kev ua haujlwm; vuam, electroplating, thiab kos duab txias yog qhov nyuaj tshwj xeeb. Electroplating thiab vuam yuav tsum tau ua nyob rau hauv lub nqus tsev vacuum los yog thaum uas muaj inert gas (nqus ion plating).
Titanium alloys yog dav siv nyob rau hauv ntau yam teb vim lawv lub zog siab, zoo corrosion kuj, thiab kub kub kuj.
Qhov ceev ntawm titanium alloy feem ntau yog nyob ib ncig ntawm 4.51g / cm3, uas tsuas yog 60 feem pua ntawm cov hlau. Qhov ceev ntawm ntshiab titanium tsuas yog ze rau cov hlau zoo tib yam. Qee qhov muaj zog titanium alloys siab tshaj lub zog ntawm ntau cov qauv hlau alloy. Yog li ntawd, lub zog tshwj xeeb (lub zog / qhov ntom) ntawm titanium alloy yog ntau dua li ntawm lwm cov khoom siv hlau, thiab cov khoom siv siab zog, zoo rigidity thiab lub teeb yuag tuaj yeem tsim tau. Titanium alloys yog siv nyob rau hauv aircraft engine Cheebtsam, skeletons, tawv, fasteners thiab tsaws iav.
304 yog lub hom phiaj dav dav hlau stainless, uas yog siv dav hauv kev tsim cov khoom siv thiab cov khoom uas xav tau kev ua haujlwm zoo (corrosion resistance and formability). Yuav kom tswj tau qhov kev tiv thaiv corrosion ntawm cov hlau tsis huv, cov hlau yuav tsum muaj ntau dua 18 feem pua chromium thiab ntau dua 8 feem pua nickel.
Qhov ceev yog 7.93 g / cm3, tseem hu ua 18/8 stainless hlau hauv kev lag luam. Nrog rau qhov kub thiab txias tsis kam ntawm 800 degrees, nws muaj cov yam ntxwv ntawm kev ua haujlwm zoo thiab kev ua haujlwm siab, thiab siv dav hauv kev lag luam, rooj tog kho kom zoo nkauj kev lag luam thiab khoom noj khoom haus thiab kev kho mob kev lag luam.
Tau kawg, titanium alloy zoo dua 304, nrog lub zog siab, tsis tshua muaj siab thiab corrosion kuj.
