Kev xeb ntawm cov hlau feem ntau yog tshwm sim los ntawm tshuaj lom neeg corrosion thiab electrochemical corrosion, thiab corrosion ntawm cov ntaub ntawv uas tsis yog xim hlau feem ntau tshwm sim los ntawm kev puas tsuaj rau lub cev thiab lub cev.
1. Tshuaj corrosion
Qhov nruab nrab ib puag ncig ncaj qha cuam tshuam nrog cov hlau nyob rau hauv qhov xwm txheej tsis muaj tam sim no, thiab ua rau nws raug puas tsuaj, xws li corrosion ntawm cov hlau los ntawm qhov kub-kub qhuav roj thiab cov tshuaj uas tsis yog electrolytic.
2. Electrochemical corrosion
Cov hlau sib txuas nrog cov electrolyte los tsim cov hluav taws xob ntws, uas yuav rhuav tshem nws tus kheej hauv kev ua electrochemical, uas yog daim ntawv tseem ceeb ntawm corrosion.
Feem ntau acid-base ntsev tov corrosion, atmospheric corrosion, av corrosion, seawater corrosion, microbial corrosion, pitting corrosion thiab crevice corrosion ntawm stainless hlau, thiab lwm yam, yog tag nrho cov electrochemical corrosion.
Electrochemical corrosion tsis tsuas yog tshwm sim ntawm ob yam khoom uas tuaj yeem ua lub luag haujlwm tshuaj, tab sis kuj vim qhov sib txawv ntawm cov concentration ntawm cov tshuaj, qhov concentration ntawm cov pa oxygen nyob ib puag ncig, qhov sib txawv me ntsis ntawm cov qauv ntawm cov khoom, thiab lwm yam. nyob rau hauv lub peev xwm yog generated, thiab lub zog ntawm corrosion yog tau. , Yog li ntawd cov hlau uas tsis tshua muaj peev xwm thiab nyob rau hauv txoj hauj lwm ntawm lub rooj tsavxwm zoo raug kev puas tsuaj.
