Differential Aeration Corrosion tshwm sim thaum muaj qhov tsis sib xws ntawm cov pa oxygen rau thaj chaw ntawm tib cov hlau tivthaiv. Nws yog ib hom electrochemical corrosion uas cuam tshuam rau cov hlau xws li hlau thiab hlau. … Qhov no yog qhov uas cov oxidation tshwm sim, cov khoom siv corrosion thiab ib lub qhov ua rau cov hlau tsis muaj zog.
Koj ua li cas tiv thaiv qhov sib txawv aeration corrosion?
CORROSION PREVENTION BY DESIGN
Cov chaw muaj pa oxygen tsawg tsim cov anode thiab yog li lawv muaj lub luag haujlwm rau corrosion. Soldering yog zoo dua rau threaded pob qij txha.
Dab tsi yog qhov sib txawv aeration?
Differential aeration corrosion yog hom kev xeb uas tshwm sim thaum cov pa oxygen sib txawv ntawm cov hlau saum npoo. Qhov sib txawv ntawm cov pa oxygen tsim ib qho anode thiab cathode ntawm cov hlau saum npoo. Oxidation tshwm sim vim hais tias ib qho anode thiab cathode tau tsim nyob rau saum npoo.
Qhov twg hauv qab no tsis yog piv txwv ntawm qhov sib txawv aeration corrosion ?
9. Qhov twg hauv qab no tsis txhawb qhov sib txawv aeration corrosion? Nqe lus piav qhia: Cov av nplaum, ib feem npog cov hlau thiab hlau laj kab hom qauvyog yam uas txhawb nqa qhov sib txawv aeration corrosion.
degree ntawm aeration cuam tshuam li cas rau corrosion?
Nyob rau hauv cov ntsiab lus, aeration accelerates anodic corrosionprocesses. … Tsis tas li ntawd, qhov tseeb corrosion puas tuaj yeem ua rau muaj kev puas tsuaj ntau dua vim tias muaj cov pa oxygen ntau ntxiv, kev txhim kho hauv cheeb tsam tuaj yeem nce tus nqi ntawm kev tawm tsam los ntawm lwm qhov kev txiav txim siab uas tuaj yeem ua rau tag nrho 100 npaug ntawm kev nkag mus.
