Taw qhia rau corrosion ntawm industrial aluminium profiles?

Peb hom ntawm corrosion ntawm industrial aluminium profiles.

1. Gap corrosion.

Gap corrosion yog vim qhov sib txawv ntawm kev siv cov hlwb inflatable, uas ua rau kom ceev qhov sib txawv corrosion, tsis muaj kev cuam tshuam sab nraum qhov sib txawv. Gap corrosion tsis muaj dab tsi ua rau hom alloy, txawm tias nws yog corrosion-resistant alloy kuj tseem tsim qhov sib txawv corrosion. Nyob rau hauv xyoo tas los no, lub mechanism ntawm interstitial corrosion tau kawm heev intensive. Lub acidic ib puag ncig nyob rau sab saum toj ntawm qhov sib txawv yog lub zog tsav ntawm corrosion.

2. Intercrystalline corrosion.

Intercrystalline corrosion yog hais txog cov ntshiab txhuas nyob rau hauv intercrystalline corrosion ntawm cov corrosion. Qhov ua rau ntawm intercrystalline corrosion yog cuam tshuam nrog kev kho cua sov tsis raug. Alloy tshuaj ntsiab lus los yog intermetallic tebchaw nyob rau hauv lub grain ciam teb los nag los nag. Piv nrog rau cov nplej, cov nplej yog tsim los ntawm anode corrosion cell, accelerating intercrystalline corrosion.

3. Filiform corrosion.

Filamentary corrosion yog feem ntau vim yog sub-membrane corrosion, qhia worm zoo li kev loj hlob nyob rau hauv zaj duab xis. Piv txwv li, zaj duab xis no tuaj yeem ua rau xim zaj duab xis, thiab nws tuaj yeem pleev xim rau, feem ntau tsis tshwm hauv qab anodic oxide zaj duab xis.
