Crevice corrosion yog ib qho chaw hauv cheeb tsam ntawm stainless hlau corrosion uas tsim nyob rau hauv nqaim, shielded qhov chaw uas cov pa tshiab tsis tuaj yeem ncig dawb. Tej qhov chaw muaj xws li flange gaskets, threaded kev twb kev txuas, clamps, lap joints, deposits, tsis tiav weld keeb kwm thiab cov cheeb tsam hauv qab rwb thaiv tsev los yog tiv thaiv npog.
Cov txheej txheem ntau ntawm cov kua dej tuaj yeem tshwm sim tau thaum cov chemistry hauv qhov crevice ua nruj dua. Oxygen depletion, poob pH thiab chloride concentration tuaj yeem tsim ib puag ncig hauv zos muaj peev xwm tawm tsam cov hlau tsis muaj zog uas tseem nyob rau ntawm qhov chaw qhib ib puag ncig.
Cov lus teb ncaj qha
Crevice corrosion pib thaum qhov sib txawv nqaim los yog tso nyiaj txwv tsis pub cov pa rov ua dua tshiab ntawm stainless hlau nto. Cov hlau hauv qhov crevice poob cov xwm txheej xav tau los tswj nws cov yeeb yaj kiab passive, thaum chloride ions thiab acidity nce hauv zos thiab ua kom cov hlau tawg.
Yog vim li cas Crevice Corrosion yog qhov nyuaj rau kev kuaj xyuas
Crevice corrosion feem ntau muab zais hauv qab lwm yam khoom lossis tso nyiaj. Cov yeeb nkab tawm sab nraud tuaj yeem ua kom huv si thaum lub phab ntsa tseem ceeb hauv qab lub gasket, kev txhawb nqa, clamp lossis sediment txheej.
