Puas muaj 718 xeb?
Inconel yog ib tsev neeg ntawm cov kev ua tau zoo alloys muaj tsib xee, paub txog nws lub zog zoo thiab kev tawm tsam rau cua sov thiab corrosion. Ib qho ntawm cov lus nug ib txwm muaj txog inconel yog seb nws xeb. Cia peb ntsaub rau cov ncauj lus no thiab tshawb nrhiav seb tus neeg ua yeeb yam li cas hauv cov chaw sib txawv.
Inconel Corrosion Kuj
Inconel alloys tau tsim tshwj xeeb los muab cov kev tshwj xeeb ua kom xeb, oxidation, thiab lwm hom kev cuam tshuam, tshwj xeeb tshaj yog nyob rau hauv cov xwm txheej. Lub xub ntiag ntawm chromium nyob rau hauv inconel ua lub luag haujlwm tseem ceeb hauv kev tsim cov txheej txheem passive oxide rau saum npoo av, uas pab tiv thaiv cov khoom ntawm xeb thiab lwm hom ntawv ntawm corrosion.
Puas muaj xeb xeb?
Technically, inconel tsis xeb hauv cov ib txwm muaj zoo li hlau lossis cov hlau. Rowing yog qhov tshwm sim ntawm cov hlau reacting nrog oxygen thiab noo noo, kev sib hom hlau oxide. Txij li thaum Inconel yog ib npib tsib xee-chromium alloy, nws tsis muaj cov hlau tseem ceeb, thiab yog li ntawd, nws tsis xeb hauv tib txoj kev.
Txawm li cas los xij, inconel tseem tuaj yeem yog corrode nyob rau hauv qee qhov xwm txheej, tab sis cov txheej txheem corrosion yog txawv ntawm cov xeb ntawm cov hlau. Inconel alloys tiv taus ntau qhov chaw muaj kev ruaj ntseg, suav nrog cov kev kub ntxhov siab, acidic mob, thiab dej qab ntsev. Kev corrosion uas tej zaum yuav tshwm sim feem ntau yog ib daim ntawv ntawm oxidation lossis pitting, tab sis nws yog qhov qeeb qeeb thiab tsis tshua muaj xeb piv rau ib txwm muaj xeb.
Yam cuam tshuam rau qhov tsis kam mus rau corrosion
1. Kub:
Inconel paub txog nws lub peev xwm los tiv thaiv kom kub siab yam tsis muaj kev nyab xeeb. Txawm li cas los xij, lub caij nyoog raug rau cov kub siab heev tuaj yeem ua rau oxidation lossis tsim ntawm lub patina nyob saum npoo.
2. Ib puag ncig:
Thaum tsis txaus siab corrosion nyob rau hauv feem ntau cov chaw ib puag ncig, tej zaum nws yuav raug kev ntxhov siab, thaum raug rau cov tshuaj chloride kev tawg, tshwj xeeb hauv cov chaw ua dej hiav txwv.
3. Alloy muaj pes tsawg leeg:
Cov qib sib txawv ntawm Inconel muaj cov qib sib txawv ntawm kev tiv taus corrosion, nyob ntawm lawv cov ntsiab lus alloying. Piv txwv li, Inconel 625 yog cov tiv taus pitting thiab crevice corrosion nyob rau hauv seawater, thaum inconel 718 muaj muaj zog tsis kam nyob rau hauv cov kev kub-qhov chaw siab.
4. Cov Mob Deg:
Inconel txoj kev tawm tsam yog feem ntau nyob ntawm qhov zoo ntawm cov oxide txheej uas ua rau saum npoo. Yog tias cov nplaim tawg lossis tsis huv, nws yuav txo cov khoom muaj peev xwm tiv taus corrosion.
