Stainless hlau kaum Corrosion daim ntawv qhia

Nyob rau hauv dav dav corrosion tej yam kev mob, lub corrosion kuj ntawmstainless hlau kaumyog ntsuas los ntawm nws tus nqi corrosion nyob rau hauv nruab nrab tej yam kev mob. Hauv qhov nruab nrab no, tus nqi corrosion ntawm stainless hlau lub kaum sab xis steel yog nyob rau hauv qhov kev tso cai ntawm kev siv, uas yog corrosion-resistant, tab sis nws tsis yog tias nws tsis corrode.

Txij li thaum muaj ntau ntawm stainless hlau lub kaum sab xis steel corrosion phau ntawv rau siv, kuj tseem muaj cov ntaub ntawv xeem ntawm stainless hlau nyob rau hauv ib tug loj tus naj npawb ntawm cov xov xwm tseeb muaj, thiab muaj ntau yam engineering xyaum kev siv stainless hlau kaum steel, ntev npaum li cas. raws li peb xaiv thiab rationally siv stainless hlau, stainless hlau Tag nrho cov kev raug mob corrosion yog kiag li tiv thaiv tau. Feem ntau hais lus, hauv kev siv tswv yim, vim tias paub txog kev tiv thaiv corrosion ntawm cov khoom siv stainless hlau stainless hlau nyob rau hauv nruab nrab ua ntej, uas yog, tus nqi corrosion, kev pab cuam lub neej ntawm stainless hlau kaum steel khoom nyob rau hauv tej yam kev mob ntawm tsim nyog siv tau. tuav.

1. Corrosion tshwm sim ntawm stainless hlau kaum steel: Corrosion tshwm sim nyob rau hauv tag nrho cov interface ntawm stainless hlau lub kaum sab xis steel nyob rau hauv kev sib cuag nrog nruab nrab ib puag ncig thiab yog yus muaj los ntawm uniform thinning raws seem, uas feem ntau tshwm sim nyob rau hauv acid thiab kub alkali nruab nrab ib puag ncig. Feem ntau corrosion kuj ntawm stainless hlau yog feem ntau soj ntsuam los ntawm corrosion tus nqi (mm/a).

2. Ua rau corrosion ntawm stainless hlau lub kaum sab xis steel: cov zaj duab xis passive tsis tuaj yeem tsim los yog cov yeeb yaj kiab passive tsis ruaj khov, thiab cov yeeb yaj kiab passive puas thiab tsis tuaj yeem kho raws sijhawm; nyob rau hauv kev siv engineering siv, nyob rau hauv ntau electrolyte corrosion ib puag ncig, stainless hlau lub kaum sab xis steel yog nyob rau hauv ib tug passive lub xeev, txawm tias nws nyob rau hauv ib tug passive xeev. Nws feem ntau yaj ntawm qhov sib txawv ntawm qhov nrawm (qee zaum txawm tias qeeb heev); Thaum kawg, nws ua tsis tiav vim qhov maj mam thinning ntawm thickness (los yog seem) ntawm stainless hlau lub kaum sab xis steel khoom, Cheebtsam, ntim, thiab lwm yam.

3. Kev ntsuas los tiv thaiv corrosion ntawm stainless hlau lub kaum sab xis steel: xaiv qib ntawm corrosion kuj raws li hom, concentration, kub thiab lwm yam kev mob ntawm corrosive nruab nrab thiab cov kev cai tshwj xeeb ntawm kev siv. Tom qab ntawd xaiv cov qib stainless hlau uas tsim nyog raws li qib kev tiv thaiv corrosion.
