Kev xaiv rau ib puag ncig txias

Corrosion Principple thiab Impact: Nyob rau hauv hiav txwv cheeb tsam uas muaj salinity thiab av noo, seawater yog heev corrosive rau nkoj. Cov ntsev hauv dej hiav txwv (feem ntau yog sodium chloride) yuav muaj cov tshuaj tiv thaiv electrochemical corrosion nrog rau saum npoo ntawm cov hlau, ua rau cov qauv ntawm cov hlau puas. Yog hais tias ib feem ntawm lub nkoj hauv qab cov dej tsis siv cov hlau tsim nyog, lub sij hawm ntev corrosion yuav ua rau txo qis hauv cov thickness thiab lub zog ntawm cov hlau, uas nyob rau hauv lem yuav cuam tshuam rau cov qauv kev ncaj ncees ntawm lub nkoj.

 

Cov yam ntxwv thiab kev xaiv ntawm Corrosion - Resistant Steels: Lub sijhawm no, corrosion - resistant marine carbon steels nrog alloying ntsiab (xws li tooj liab thiab chromium) yuav tsum tau xaiv. Cov khoom siv tooj liab tuaj yeem hnov ​​​​mob nrog oxygen thiab dej nyob rau saum npoo ntawm cov hlau los tsim cov yeeb yaj kiab tiv thaiv ntom ntom, tiv thaiv cov dej hiav txwv los ntawm cov hlau txuas ntxiv. Cov khoom chromium tuaj yeem txhim kho lub peev xwm passivation ntawm cov hlau nyob rau hauv ib puag ncig marine, ua rau cov hlau nto los ua ib qho kev ruaj khov passivation zaj duab xis thiab txo tus nqi corrosion. Cov corrosion - resistant marine carbon steels tuaj yeem ua tau zoo rau kev pab cuam lub neej ntawm cov nkoj hauv qhov chaw siab - corrosion thiab txo qhov zaus ntawm kev saib xyuas thiab hloov cov khoom siv.

 

 

 

 

 

 

 

ABS yog hais txog American Bureau of Shipping, tus tswv cuab ntawm Internation Classification Society.

Qib A feem ntau yog siv rau hauv kev thauj mus los hauv hiav txwv nkoj nuv ntses, kev txhim kho dej hiav txwv, kev cawm thaum muaj xwm txheej ceev, dej khov nab kuab, kev tshawb fawb nkoj, lub thawv ntim khoom, nkoj saib thiab nws qhov chaw.

 

Qib A yog lub nkoj hull siv steel phaj nrog lub zog ib txwm muaj. Nws muaj ABDE 4 qib.

 

Kev xaiv rau High - Temperature Environments (xws li nyob ze ntawm Lub Nkoj Lub Cav Chav)

 

Kev cuam tshuam ntawm Kev Kub Kub Kub rau Cov Khoom Siv Hlau: Nyob rau hauv qhov kub thiab txias ib puag ncig xws li nyob ze ntawm lub nkoj lub cav chav tsev, cov hlau yuav ntsib teeb meem xws li kev txo qis zog thiab muaj zog oxidation. Raws li qhov kub thiab txias, cov atomic thermal txav hauv cov hlau hnyav zuj zus, thiab cov qauv lattice hloov, ua rau txo qis ntawm cov khoom siv zog thiab tensile lub zog ntawm cov hlau. Nyob rau tib lub sijhawm, cov tshuaj tiv thaiv ntawm cov hlau thiab cov pa oxygen yog khaus ntau dua nyob rau hauv qhov chaw kub thiab txias, thiab oxide nplai tau yooj yim tsim, ntxiv cuam tshuam rau cov khoom ntawm cov hlau.

 

Kev txiav txim siab rau Tsim Nyog Steels: Rau qhov chaw kub kub zoo li no, nws yog ib qho tsim nyog yuav tsum xaiv cov hlau uas muaj qhov kub thiab txias zog thiab muaj zog antioxidant. Qee cov marine carbon steels uas muaj cov ntsiab lus alloying xws li molybdenum thiab vanadium tuaj yeem txiav txim siab. Molybdenum tuaj yeem txhim kho lub siab kub lub zog ntawm cov hlau los ntawm kev tsim cov carbide ruaj khov los tiv thaiv kev loj hlob ntawm cov nplej, yog li tswj lub zog ntawm cov hlau ntawm qhov kub thiab txias. Vanadium muaj cov haujlwm zoo sib xws thiab tuaj yeem txhim kho qhov nkag siab ntawm cov hlau, ua kom ruaj khov ntawm cov duab thiab qhov loj ntawm cov hlau nyob rau hauv lub sij hawm ntev ntawm qhov kub thiab txias.
