Kev sim tshuaj tsuag ntsev yog ib qho kev ntsuam xyuas ib puag ncig uas tsuas yog siv artificially simulated ntsev tsuag ib puag ncig kev tsim los ntawm ntsev txau tshuaj ntsuas cov khoom siv los ntsuas qhov tsis kam ntawm corrosion ntawm cov khoom lossis cov khoom siv hlau. Nws tau muab faib ua ob pawg, ib qho yog qhov kev paub txog kev nyab xeeb ib puag ncig, thiab lwm qhov yog qhov ntsuas nrawm ua kom lub teeb tsuag ntsev tsuag ib puag ncig kev ntsuam xyuas. Cov cuab yeej pleev xim sim ntsev ib puag ncig kev ntsuam xyuas yog siv hom ntsuas cov khoom siv nrog qee qhov ntim qhov chaw-lub ntsev tsuag tshuaj ntsuam lub thawv, hauv nws qhov chaw ntim, cov txuj ci cuav yog siv los tsim cov tshuaj tsuag ntsev ib puag ncig los ntsuas qhov zoo ntawm cov ntsev tsuag corrosion tsis kam ntawm cov khoom.
Muab piv nrog cov huab cua ib puag ncig, cov ntsev ntsev ntawm chloride nyob rau hauv cov ntsev tsuag ib puag ncig zoo tuaj yeem yog ob peb zaug lossis kaum tawm zaug ntawm cov ntsev dej tsuag cov ntsiab lus ntawm ib puag ncig ntuj. Piv txwv li, yog tias cov khoom lag luam raug sim hauv qhov chaw raug paug hauv lub ntuj, nws yuav siv sijhawm 1 xyoo rau nws qhov kev xeb, thaum qhov kev kuaj ntawd nyob rau hauv kev sim ntsev cov tshuaj tsuag dej ib puag ncig yuav tsum tau tsuas yog 24 teev kom tau cov txiaj ntsig zoo sib xws.
