Dab tsi Alloying Elements tuaj yeem ntxiv rau Marine Class Eh36 Shipbuilding Steel Phaj los txhim kho corrosion kuj?

Kev tiv thaiv corrosion ntawm Marine Class Eh36 shipbuilding steel daim hlau yog ib qho tseem ceeb ntawm kev txiav txim siab lawv cov kev ua tau zoo thiab kev ua haujlwm ntev nyob rau hauv marine ib puag ncig. Kev koom ua ke tshwj xeeb alloying ntsiab tuaj yeem txhim kho cov cuab yeej no.

Chromium yog ib qho tseem ceeb alloying lub luag haujlwm uas ua lub luag haujlwm tseem ceeb. Nws tsim cov txheej txheem tiv thaiv oxide rau ntawm cov hlau, tiv thaiv kev nkag mus ntawm cov kab mob corrosive xws li dej ntsev thiab roj marine gases. Lub xub ntiag ntawm chromium txhim kho cov hlau muaj peev xwm tiv thaiv oxidation thiab pitting corrosion, ua rau nws ruaj khov nyob rau hauv hnyav marine tej yam kev mob.

Nickel yog lwm qhov tseem ceeb ntxiv. Nws pab txhim kho cov hlau tsis kam rau kev xeb thiab kev ntxhov siab corrosion tawg. Nickel kuj tseem ua rau cov hlau tsis muaj zog thiab ductility, uas yog qhov tseem ceeb rau kev tiv thaiv cov kev ntxhov siab thiab cov neeg kho tshuab kev ntxhov siab los ntawm cov nkoj tsim cov phiaj hauv marine ib puag ncig.

Molybdenum tseem muaj txiaj ntsig zoo thiab. Nws ua rau cov hlau tsis muaj zog rau pitting thiab crevice corrosion, tshwj xeeb tshaj yog nyob rau hauv chloride-nplua nuj ib puag ncig zoo li dej hiav txwv. Molybdenum kuj tseem txhim kho cov hlau hardenability thiab lub zog ntawm qhov kub siab.
