Raws li lub ntsiab lus ntawm crevice corrosion piav qhia, muaj ob txoj hauv kev los txo qhov kev pheej hmoo ntawm crevice corrosion:
Tshem tawm qhov khoob me me uas yuav ntxiab electrolyte thiab ua rau stagnation
Khaws cov electrolyte ntws mus dawb los yog siab txaus kom tsis txhob stagnation
Txawm li cas los xij, ntau yam tuaj yeem cuam tshuam tag nrho cov kev pheej hmoo tag nrho thiab qhov hnyav ntawm qhov kev txhim kho corrosion ib zaug:
Crevice hom:Hlau rau hlau thiab hlau rau nonmetal crevices feem ntau yuav coj txawv txawv.
Cov yam ntxwv ntawm lub cev crevice:Txhua yam los ntawm qhov sib txawv loj mus rau qhov tob thiab qhov chaw zoo nkauj nyob rau hauv thiab ib ncig ntawm lub crevice tuaj yeem cuam tshuam kev pheej hmoo corrosion thiab kev loj hlob.
Hlau muaj pes tsawg leeg:Alloys yuav muab ntau theem ntawm crevice corrosion kuj. Feem ntau, tib cov alloys uas muaj zog pitting corrosion kuj tseem muaj kev txhim kho crevice corrosion kuj.
Kev siv ib puag ncig:Cov kav dej uas muaj chav txaus rau electrolytes kom circulate thiab nrog cov dej ntws ntau dua yuav tiv thaiv crevice corrosion zoo dua. Qhov no yog vim tias muaj tsawg dua cov hnab tshos ntawm cov khoom siv hluav taws xob tsis txav thiab txawm tias cov khoom siv electrolyte yuav raug kaw, cov nqi ntws ntau dua yuav pab pauv cov khoom siv electrolyte nrog cov tshiab sai txaus kom tsis txhob pib ntawm corrosion.
Qhov xwm txheej ntawm cov tshuaj electrolyte: daws qhov kub thiab txias, pH qib, qib oxygen, halide lossis chloride ions, thiab lwm yam tuaj yeem cuam tshuam tsis tsuas yog kev pheej hmoo ntawm corrosion tab sis yuav ua li cas aggressively lub corrosion yuav kis tau yuav tsum pib nres.
Cov kauj ruam meej los txo lossis tshem tawm qhov kev pheej hmoo ntawm kev puas tsuaj yuav txawv raws li koj qhov kev tsim cov kav dej, qhov chaw ua haujlwm, thiab kev npaj siv.
Txawm li cas los xij, cov hauv qab no yog cov ntsiab lus pib zoo uas yuav cuam tshuam rau ntau yam ntawm cov kav dej thiab siv rooj plaub:
Siv pob tw weld pob qij txha es tsis txhob bolted lossis threaded pob qij txha rau cov khoom siv tshiab
Siv nruam vuam los yog soldering kom tshem tawm crevices nyob rau hauv lub puab tsaig pob qij txha
Ua kom tiav cov dej ntws ntawm cov hlab ntsha qhov twg ua tau thiab tsim txhua qhov chaw tsis muaj dej kom tso cai kom txaus txaus los tiv thaiv stagnation
Siv cov khoom uas tsis yog-absorbent yog qhov ua tau
Siv cov alloys ntaus nqi siab dua los ntawm ASTM G48 cov qauv rau kev ua kom muaj zog ntxiv rau crevice corrosion
