Kev ua haujlwm ntawm Metallographic electrolytic Corrosion 'meter

Misionallographic electrolytic corrosion '' tus ntsuas siv rau cov khoom siv hlau, uas tau siv dav hauv cov khoom siv science, metallurgy thiab hlau ua. Daim ntawv no yuav qhia txog kev siv cov hlauTallographic electrolytic corrosion 'meter.

Cov kauj ruam ntawm Metallographic electrolytic corrosion 'metrid' yog raws li hauv qab no:

Kauj ruam 1: Npaj cov qauv.

Kev npaj ntawm cov qauv hlau kom raug pom kom pom qhov loj me feem ntau yuav tsum tau txiav, polishing thiab tu kom ntseeg tau tias saum npoo ua tiav thiab huv si.

Kauj Ruam 2: Xaiv cov electrolyte tsim nyog. Xaiv cov ntawv tsim nyog electrolyte raws li cov khoom siv thiab kev soj ntsuam yuav tsum muaj ntawm cov qauv. Feem ntau siv cov electrolytes suav nrog cov acidic electrolyte (xws li cov tshuaj electrolyte (xws li sodium hydroxide tov, thiab lwm yam).

Kauj Ruam 3: Raws li cov yam ntxwv ntawm cov ntaub ntawv hlau thiab kev soj ntsuam yuav tsum tau, qhov ceev tam sim no, hluav taws xob thiab lub sijhawm corrosion yog hloov kho kom zoo.
Cov kev xaiv ntawm cov teeb meem no yuav tsum tau ua kom zoo raws li kev paub thiab kev sim cov txiaj ntsig tiag tiag.

Kauj ruam 4: Pib txoj kev xeb. Tso cov qauv rau hauv lub xov tooj electrolytic, xyuas kom cov qauv yog nyob rau hauv tag nrho cov qauv yog nyob rau hauv cov electrolyte, thiab txuas lub zog hluav taws xob, thiab txuas lub zog hluav taws xob kom pib tam sim no.

Kauj Ruam 5: Saib xyuas cov txheej txheem corrosion. Soj ntsuam cov kev hloov ntawm cov qauv ntawm cov qauv, feem ntau raws li lub tshuab tsom. Raws li qhov xav tau, ntau ntau corrosion thiab kev soj ntsuam tuaj yeem nqa tawm kom txog thaum zoo txaus siab micrettructure yog tau.

Kauj Ruam 6: Nres corrosion thiab huv cov qauv. Thaum zoo siab microstructure yog pom, qhov tam sim no nres, cov qauv raug tshem tawm los ntawm electrolyzer thiab huv si cov khoom lag luam electrolyte thiab corrosion khoom.

Hauv luv luv, ntaus cim corrosion yog ib qho tseem ceeb siv cov cuab yeej tseem ceeb ntawm cov hlau thiab txheeb xyuas cov qauv hlau los ntawm etching saum npoo. Qhov tseeb ntawm txoj ntsiab cai thiab cov qauv siv raug tuaj yeem ua rau qhov raug thiab ntseeg tau kev txhawb nqa rau kev tshawb fawb thiab kev ua hlau.
