1. Vim li cas titanium cov ntaub ntawv tau siv ntau ntxiv hauv Marine Engineering?
Nrog rau kev txhim kho cov roj thiab roj av, dej hiav txwv desalination, offshore cua fais fab, nkoj tsim, sib sib zog nqus- cov khoom siv dej hiav txwv, thiab cov thev naus laus zis siv hluav taws xob txuas ntxiv mus, marine engineering qhov chaw xav tau ntau ntxiv ntawm cov khoom siv corrosion, lub zog, qhov hnyav, thiab ntev - lub sij hawm cia siab rau.
Piv nrog rau thaj av -raws li kev lag luam ib puag ncig, marine ib puag ncig yog qhov nyuaj dua. Cov dej hiav txwv muaj ntau cov tshuaj chloride ions thiab lwm cov ntsev, thaum cov khoom siv kuj raug rau cov av noo siab, tidal variations, seawater flow, thiab marine biofouling. Nyob rau lub sijhawm ntev - raug dej hiav txwv, cov pa roj carbon steel thiab qee cov hlau tsis zoo yuav ntsib teeb meem xws li pitting corrosion, crevice corrosion, kev nyuaj siab corrosion, thiab cov nqi kho mob ntxiv.
Titanium thiab titanium alloysmuab cov seawater corrosion kuj zoo heev, lub zog siab - rau - qhov hnyav piv, kev ua haujlwm zoo qaug zog, thiab lub neej ua haujlwm ntev. Yog li ntawd, lawv tau siv dav hauv cov khoom siv hauv marine engineering uas yuav tsum muaj kev ntseeg siab ntawm cov khoom siv siab.
2. Vim li cas Titanium thiaj haum rau Marine Engineering?
1. Zoo heev Seawater Corrosion Resistance
Thaum titanium raug huab cua los yog dej, nws sai sai tsim ib tug ruaj khov thiab ntom oxide zaj duab xis ntawm nws nto. Qhov no passive zaj duab xis tiv thaiv titanium substrate thiab muab titanium zoo heev corrosion kuj nyob rau hauv ntuj seawater.
Tshwj xeeb tshaj yog nyob rau hauv seawater ib puag ncig uas muaj chloride ions, titanium qhia tau zoo heev tsis kam mus rau dav dav thiab localized corrosion. Qee cov ntaub ntawv luam tawm qhia txog tus nqi corrosion ntawm kwv yees li0.8nm / xyoorau titanium alloys hauv dej hiav txwv.
