AH32 DH32 EH32 Shipbuilding Steel Phaj

Alloying Elements rau Txhim Kho Corrosion Resistance hauv AH32, DH32, thiab EH32 Shipbuilding Steel Phaj

Nyob rau hauv lub cheeb tsam ntawm kev tsim cov nkoj, qhov corrosion kuj ntawm steel daim hlau xws li AH32, DH32, thiab EH32 yog qhov tseem ceeb tshaj plaws los xyuas kom meej lub neej ntev thiab kev nyab xeeb ntawm cov hlab ntsha. Qhov sib ntxiv ntawm cov ntsiab lus alloying tshwj xeeb tuaj yeem txhim kho cov cuab yeej tseem ceeb no.

Chromium (Cr) yog ib qho ntawm cov ntsiab lus tseem ceeb alloying uas tuaj yeem txhim kho corrosion kuj ntawm cov hlau phaj. Thaum ntxiv rau qhov tsim nyog, feem ntau yog li ntawm 10% mus rau 30%, chromium tsim ib txheej oxide passive rau ntawm cov hlau. Cov txheej txheem no ua ib qho thaiv, tiv thaiv kev nkag mus ntawm cov kab mob corrosive xws li dej ntsev thiab oxygen. Cov ntaub ntawv qhia tau hais tias txawm tias ib qho me me ntawm cov ntsiab lus chromium, hais los ntawm 10% mus rau 15%, tuaj yeem ua rau muaj kev txhim kho zoo hauv kev tiv thaiv corrosion, nrog rau kev txo qis ntawm corrosion mus txog 50%.

Nickel (Ni) yog lwm lub ntsiab lus uas ua lub luag haujlwm tseem ceeb. Incorporating npib tsib xee nyob rau hauv thaj tsam ntawm 2% mus rau 10% tuaj yeem txhim kho cov hlau tsis kam rau ob qho tib si corrosion thiab pitting corrosion. Nws pab kom ruaj khov rau cov yeeb yaj kiab passive thiab txhim kho cov hlau muaj peev xwm tiv taus qhov chaw corrosive. Cov txiaj ntsig kev sim qhia tau hais tias qhov sib ntxiv ntawm 5% npib tsib xee tuaj yeem ua rau muaj kev tiv thaiv pitting corrosion los ntawm kwv yees li 30%.

Molybdenum (Mo) muaj txiaj ntsig zoo hauv kev txhim kho corrosion kuj, tshwj xeeb tshaj yog nyob rau hauv ib puag ncig uas muaj chloride nplua nuj xws li dej hiav txwv. Txawm tias qhov sib ntxiv me me ntawm ib ncig ntawm 0.5% mus rau 2% tuaj yeem muaj qhov cuam tshuam tseem ceeb. Nws txhim khu lub passivation ntawm steel nto thiab txo qhov susceptibility rau localized corrosion. Cov kev tshawb fawb pom tau hais tias kev suav nrog 1% molybdenum tuaj yeem txo qis tus nqi corrosion li ntawm 20%.

Copper (Cu) kuj muaj txiaj ntsig. Thaum ntxiv rau hauv cov nyiaj xws li 0.5% mus rau 2%, nws tuaj yeem pab txhim kho corrosion kuj. Tooj liab pab tsim cov yeeb yaj kiab tiv thaiv thiab inhibits kev nkag mus ntawm corrosive hom. Cov ntaub ntawv qhia tias 1% ntxiv ntawm tooj liab tuaj yeem ua rau txo qis kev puas tsuaj los ntawm kwv yees li 15%.

Aluminium (Al) tuaj yeem muab ntxiv rau hauv qhov me me, feem ntau tsawg dua 1%. Nws pab tsim cov txheej txheej oxide tuab ntawm cov hlau, muab kev tiv thaiv ntxiv tiv thaiv corrosion.

Titanium (Ti) thiab niobium (Nb) feem ntau tau ntxiv rau hauv cov lej, feem ntau tsawg dua 0.1%. Cov ntsiab lus no pab hauv cov nplej refinement thiab stabilization ntawm microstructure, uas ua rau tsis ncaj ncees rau kev txhim kho corrosion los ntawm kev txo qhov cuam tshuam rau intergranular corrosion.
