Lub Hom Phiaj Ntawm Titanium Rods Yog Dab Tsi
Ua ntej txhua yam, qhov zoo ntawm titanium pas nrig muaj ntau dua, tsis tsuas yog lub zog siab, tsis tshua muaj ntom ntom nti, tab sis kuj tseem muaj cov cuab yeej zoo, kev ua hauj thiab kev ua hauj corrosion. Yog li dab tsi yog qhov siv ntawm titanium pas nrig? Cia kuv qhia nws rau koj.
Kev lag luam kev tsim khoom lag luam ntawm titanium tau pib xyoo 1948. Qhov kev thov rau kev tsim kho aviation kev lag luam tau ua rau kev lag luam titanium tsim tawm ntawm qhov nruab nrab txhua xyoo kev loj hlob ntawm kwv yees li 8%. Kev tso tawm thoob ntiaj teb kev lag luam tam sim no ntawm titanium alloy cov khoom siv tau mus txog ntau dua 40,000 tons, thiab muaj ze li 30 titanium alloy cim lag luam. Kev siv cov alloys siv ntau tshaj yog Ti-6Al-4V (TC4), Ti-5Al-2.5Sn (TA7) thiab muaj cov ntshiab titanium (TA1, TA2 thiab TA3). Titanium alloys tsuas yog siv rau kev tsim cov khoom siv dav hlau cav cov tshuab ua haujlwm, tom qab ntawd cov txheej txheej ntawm pob zeb loj, cov foob pob thiab cov dav hlau siab. Hauv nruab nrab xyoo 1960, titanium thiab nws cov alloys tau siv rau hauv kev lag luam dav dav, siv los ua hluav taws xob hauv kev lag luam electrolysis, condensers hauv chaw nres tsheb fais fab, tso cua sov rau roj av tawm thiab desalination, thiab ib puag ncig kev ua qias tuaj. Titanium thiab nws cov alloys tau dhau los ua ib hom corrosion-resistant txheej khoom.
Tsis tas li ntawd, nws tseem siv los tsim cov khoom siv hydrogen khaws cia thiab ua kom lub cim xeeb alloys. Titanium alloy yog qhov txheej txheem kev teeb tsa khoom tshiab tseem ceeb siv hauv kev lag luam dav hlau. Nws lub zog nqus tshwj xeeb, lub zog thiab kev ua haujlwm kub nyob nruab nrab ntawm txhuas thiab hlau, tab sis nws muaj lub zog muaj zog thiab zoo heev seawater corrosion tsis kam thiab ultra-low kub ua haujlwm. Tus nqi ntawm titanium alloy hauv aero xyaw feem ntau ua rau 20% mus rau 30% ntawm tag nrho qhov hnyav ntawm qhov txheej txheem. Nws yog tsuas yog siv los ua compressor qhov chaw, xws li cam khwb cia titanium kiv cua, compressor disks thiab blades, cam khwb cia titanium compressor casings, casing hauv nruab nrab, Cov kabmob hauv tsev, thiab lwm yam. Cov khoom siv dav siv feem ntau ntawm lub zog tshwj xeeb, corrosion tsis kam thiab tsis kub tiv thaiv ntawm titanium alloys los ua ntau yam siab txog ntsha, roj tso tsheb hlau luam, khawm ris nrawm, ntsuas cov twj, cov qauv thiab foob pob hluav taws. Artificial Earth satellites, lunar modules, manned spacecraft thiab chaw shuttles kuj siv titanium alloy ntawv vuam.
