Kev tiv thaiv corrosion ntawm titanium porous phaj hais txog lawv lub peev xwm los tiv thaiv corrosion thaum raug corrosive ib puag ncig. Corrosion yog ib qho tshuaj lom neeg lossis electrochemical cov tshuaj tiv thaiv uas tshwm sim thaum cov khoom siv los rau hauv kev sib cuag nrog nws ib puag ncig, ua rau muaj kev puas tsuaj saum npoo, tawg ntawm cov hlau ions, lossis tsim cov khoom siv corrosion.
Porous Titanium phaj
50vs5 ua
Porous titanium phaj feem ntau yog ua los ntawm high-purity titanium hlau thiab muaj ib tug tshwj xeeb ntxeem tau qauv thiab loj deg cheeb tsam. Cov qauv tshwj xeeb no qhia txog qee theem ntawm kev tiv thaiv corrosion rau porous titanium daim hlau.
Qhov kev tiv thaiv corrosion ntawm porous titanium daim hlau tuaj yeem txiav txim siab los ntawm ntau txoj hauv kev sim thiab ntsuas. Nov yog qee txoj hauv kev uas feem ntau siv:
Kev Xeem Electrochemical
Kev Xeem Electrochemical: Kev ntsuam xyuas hluav taws xob hluav taws xob yog ib txoj hauv kev siv los ntsuas qhov kev tiv thaiv corrosion ntawm cov khoom hauv ib puag ncig tshwj xeeb. Piv txwv li, kev ntsuam xyuas polarization nkhaus lossis electrochemical impedance spectroscopy tuaj yeem ua haujlwm los kawm txog tus cwj pwm electrochemical thiab corrosion tsis kam ntawm porous titanium daim hlau hauv cov tshuaj chloride.
Kev kuaj Corrosion: Ntau yam kev ntsuam xyuas corrosion, xws li kev sim immersion tests thiab cyclic corrosion tests, yuav ua tau los soj ntsuam cov corrosion kuj ntawm porous titanium daim hlau nyob rau hauv txawv corrosive media. Thaum lub sij hawm kev ntsuam xyuas, kev ntsuas ntawm huab hwm coj poob thiab kev hloov pauv ntawm qhov chaw morphology tuaj yeem ua tau.
Kev txheeb xyuas cov khoom: Cov txheej txheem kev txheeb xyuas cov khoom sib txawv, xws li scanning electron microscopy (SEM) thiab lub zog-dispersive X-ray spectroscopy (EDS), tuaj yeem siv los saib xyuas cov morphology saum npoo thiab muaj pes tsawg leeg ntawm porous titanium daim hlau, yog li txheeb xyuas qhov corrosion, oxidation, lossis lwm yam. degradation phenomena.
Txoj kev poob phaus: Txoj kev no suav nrog kev nthuav tawm titanium daim hlau porous rau cov xov xwm corrosive tshwj xeeb rau qee lub sijhawm thiab ntsuas qhov hnyav. Los ntawm kev sib piv qhov hnyav thawj zaug nrog qhov hnyav tom qab corrosion, qhov corrosion kuj ntawm cov khoom tuaj yeem ntsuas.
Kev Ntsuas Tshuaj Tsuag
Kev Ntsuas Tshuaj Tsuag: Kev ntsuam xyuas cov tshuaj ntsev muaj xws li nthuav tawm cov titanium porous daim hlau mus rau qhov chaw ntsev ntsev kom simulate tej yam kev mob tshwm sim nyob rau hauv marine los yog high-salinity ib puag ncig. Kev coj tus cwj pwm corrosion ntawm cov khoom raug soj ntsuam thiab kaw thaum lub sijhawm kuaj, nrog rau kev tshuaj xyuas thiab ntsuas lub sijhawm.
Electrochemical Impedance Spectroscopy (EIS): Kev kuaj EIS suav nrog ntsuas cov electrochemical impedance ntawm porous titanium daim hlau hauv corrosive media. Los ntawm kev txheeb xyuas qhov impedance spectra, qhov kev tiv thaiv corrosion thiab kinetics ntawm cov txheej txheem corrosion tuaj yeem raug soj ntsuam.
Kev ntsuas Corrosion Rate: Tus nqi corrosion ntawm porous titanium daim hlau hauv cov xov xwm corrosive tshwj xeeb tuaj yeem ntsuas los ntsuas lawv cov kev tiv thaiv corrosion. Cov txheej txheem xws li linear polarization lossis Tafel txoj kab nqes tuaj yeem ua haujlwm los txiav txim siab tus nqi corrosion.
Corrosion Product Analysis: Kev tshuaj xyuas cov khoom siv corrosion tsim los ntawm cov porous titanium daim hlau hauv corrosive media, siv cov tswv yim xws li X-ray diffraction (XRD) lossis lub zog-dispersive spectroscopy (EDS), tuaj yeem muab kev nkag siab txog cov txheej txheem corrosion thiab qhov xwm ntawm cov khoom, yog li cia kev ntsuam xyuas ntawm cov khoom siv corrosion kuj.
