Nyob rau hauv xyoo tas los no, titanium daim hlau tau siv ntau dua thiab dav hauv kev lag luam fais fab. Ua ke nrog lub zog tshwj xeeb, kev tiv thaiv corrosion thiab kev qaug zog zoo ntawm titanium alloy daim hlau, titanium daim hlau tau dav siv hauv chav turbine blades, generator guard rings thiab lwm yam kev thov. Nws tau nyiam cov xim zoo los ntawm cov kws tshaj lij engineers thiab manufacturers. Hnub no kuv yuav muab lus qhia luv luv rau koj.
Vim muaj lub zog tshwj xeeb, kev ua haujlwm zoo qaug zog thiab kev tiv thaiv corrosion ntawm titanium alloy daim hlau, nws kuj yog tsim rau cov hniav ntawm chav turbines, feem ntau yog cov theem kawg ntawm qhov qis qis. Feem ntau chav turbine hniav yog ua los ntawm martensitic chromium stainless hlau. Qhov tshwj xeeb lub ntiajteb txawj nqus ntawm steel yog loj, thiab rau high-ceev rotating chav turbines, steel hniav yuav tsum dais loj loj centrifugal quab yuam.
Tsis tas li ntawd, chloride theem sulfide feem ntau muaj nyob rau hauv cov dej vapor, uas yog tshwm sim los ntawm cov laj thawj xws li condenser to. Cov xov xwm no ua rau pitting corrosion ntawm cov hniav, thiab crevice corrosion yog tsim ntawm cov hniav hauv paus hniav thiab cov hniav tip los yog ntawm khi bar, thiab corroded ib feem yuav dhau los ua cov kab nrib pleb. Kev qaug zog ntawm Crl3 steel kuj tsis zoo tagnrho, nyob rau hauv ib puag ncig corrosive nrog saturated sodium chloride tov, tshwj xeeb tshaj yog nyob rau hauv cov ntaub ntawv ntawm pH qis thiab yaj oxygen, lub zog qaug zog ntawm Crl3 steel yog heev txo. Nrog titanium hniav ncaj qha nyob rau hauv qhov chaw ntawm cov hlau hniav nyob rau hauv thawj geometry, qhov teeb meem no zoo heev. Lub titanium hniav yog lub teeb, thiab lub zog centrifugal ntawm lub hauv paus ntawm cov hniav tuaj yeem raug txo los ntawm 40 feem pua ntawm tib qhov ceev. Tsis tas li ntawd, qhov kev tiv thaiv corrosion ntawm titanium hniav rau cov ntsev uas muaj cov pa yog qhov zoo dua li ntawm cov hlau, thiab kev qaug zog ntawm chinganjin kuj siab dua li cov hlau tsis muaj steel.
Hauv huab cua, lub zog qaug zog ntawm Ti-6A1-4Y alloy yog li 30 feem pua siab dua li ntawm Cr13 steel, thiab lub zog qaug zog ntawm Crl3 steel hauv sodium chloride tov yog qis dua los ntawm 2/{ {6}/5. Lub zog qaug zog ntawm titanium alloys tsis cuam tshuam. Yog li ntawd, xav txog qhov zoo thiab qhov tsis zoo ntawm kev qaug zog ua haujlwm nyob rau hauv cov xwm txheej corrosion, nws yog qhov tseem ceeb tshaj plaws los hloov titanium nrog hlau.
Titanium alloy daim hlau kuj tseem siv tau los ua lub tshuab hluav taws xob tiv thaiv nplhaib. Nyob rau hauv tag nrho cov turbine generator system, lub nplhaib zov yog ib qho tseem ceeb. Cov kev xav tau ntawm lub tshuab hluav taws xob loj rau lub nplhaib tiv thaiv yog lub zog siab, zoo tawg tsis kam, tsis hnov tsw rau kev ntxhov siab corrosion cracking hauv dej nruab nrab, thiab yuav tsum tsis yog hlau nplaum. Cov nplhaib tuav tam sim no yog ua los ntawm austenitic Fe-Mn-Cr alloys, uas muaj lub zog muaj zog rau kev ntxhov siab corrosion tawg thiab muaj teeb meem nrog kev ntseeg siab kom ncav cuag lub zog siab.
