Kev txheeb xyuas qhov corrosion ntawm cov kav hlau stainless yog qhov tseem ceeb los xyuas kom meej tias lawv txoj haujlwm nyab xeeb thiab txuas ntxiv lawv lub neej kev pab cuam. Nov yog qee txoj hauv kev nrhiav kom tau zoo:
Kev kuaj pom pom yog txoj hauv kev yooj yim tshaj plaws ua ntej. Ua tib zoo saib ntawm qhov chaw ntawm cov yeeb nkab steel hlau nrog lub qhov muag liab qab kom pom tias muaj cov xwm txheej txawv txav xws li xeb, tawg, tawg, pits, lossis bulges. Nyob rau tib lub sijhawm, ua tib zoo saib xyuas cov welds, pob qij txha, thiab lwm qhov chaw uas ua rau corrosion.
Siv cov cuab yeej ntsuas tsis muaj kev puas tsuaj, xws li kev sim tam sim no. Cov qauv no siv cov hauv paus ntsiab lus ntawm cov hluav taws xob hauv hluav taws xob tsis xws luag thiab ze ntawm cov yeeb nkab, thiab ntsuas qhov tseeb ntawm cov yeeb nkab.
Ultrasonic kuaj kuj yog ib qho ntawm cov kev siv feem ntau. Nws txiav txim siab seb puas muaj teeb meem xws li corrosion thinning, qhov, los yog kab nrib pleb hauv cov yeeb nkab los ntawm emitting ultrasonic nthwv dej thiab tau txais reflected tsis. Txoj kev no tuaj yeem kuaj xyuas corrosion hauv qhov tob ntawm cov yeeb nkab.
Lwm txoj hauv kev yog kev ntsuas nkag. Siv ib tug penetrant uas muaj fluorescent los yog colorant rau saum npoo ntawm stainless hlau yeeb nkab. Nyob rau hauv qhov kev txiav txim capillary, lub penetrant yuav nkag mus rau qhov tsis xws luag ntawm qhov qhib qhov chaw, thiab tom qab ntawd tshem tawm qhov tob tob ntawm qhov chaw, siv tus tsim tawm, thiab tom qab ntawd qhia cov duab thiab qhov chaw ntawm qhov tsis xws luag.
Kev tshuaj xyuas tshuaj tuaj yeem kuaj xyuas cov kev hloov hauv cov tshuaj muaj pes tsawg leeg ntawm cov kav dej stainless hlau los txiav txim seb puas muaj corrosion tshwm sim. Piv txwv li, los ntawm kev ntsuas cov ntsiab lus ntawm cov ntsiab lus tseem ceeb xws li chromium thiab npib tsib xee, nws muaj peev xwm los ntsuam xyuas seb qhov corrosion kuj ntawm stainless hlau puas cuam tshuam.
Tsis tas li ntawd, txoj kev tshawb nrhiav electrochemical xws li kev ntsuas polarization nkhaus thiab AC impedance spectroscopy ntsuas tuaj yeem muab cov ncauj lus kom ntxaws txog tus nqi corrosion thiab corrosion mechanism ntawm stainless hlau kav.
Rau cov kav hlau stainless uas tau siv nyob rau hauv ib puag ncig hnyav rau lub sijhawm ntev, kev soj ntsuam cov ntsiab lus tuaj yeem teeb tsa thiab cov qauv tuaj yeem sau tsis tu ncua rau kev soj ntsuam hauv chav kuaj, suav nrog kev tshuaj ntsuam metallographic, scanning electron microscopy soj ntsuam, thiab lwm yam, kom raug ntsuas qhov degree thiab hom corrosion.
Kev siv dav dav ntawm ntau txoj kev tshawb pom saum toj no tuaj yeem nkag siab thiab nkag siab qhov kev txhim kho ntawm cov kav hlau tsis muaj steel hlau thiab ua raws li kev saib xyuas thiab kho kev ntsuas tam sim.
