Nusiwo wotsɔna tso duta vɛ ƒe sia ƒe sɔ gbɔ ŋutɔ.

1. Anyigba dzi numekuku le gakpo si mexɔ dzo o ŋu .

Woate ŋu azã AES mɔnu kple SPS mɔnu siaa atsɔ adzro gakpo si mexɔ dzo o ƒe anyigba dzi atsɔ anya gakpo si mexɔ dzo o ƒe ememe kple egodo ƒe xɔxlɔ̃ ƒe ŋutete. Kukuɖenuŋu ƒe didime si AES ɖena ɖe go la le sue ŋutɔ, si ate ŋu anye 20nm. Eƒe dɔ gbãtɔe nye be wòade dzesi nusiwo le eme. XPS mɔnu ƒe numekuku ƒe asixɔxɔ anɔ abe 10μm ene, si wozãna koŋ tsɔ nyaa nusiwo le nusiwo te ɖe anyigba ŋu ƒe atike ƒe nɔnɔme.

Ga si mexɔ dzo o ƒe anyigba si wotsɔ mɔ̃ wɔe si wotsɔ mɔ̃ wɔe si wotsɔ gakpo si mexɔ dzo o si wotsɔ AEwo kple XPS detektɔwo do goe la ɖee fia be numekuku goglome si bɔ wu le gakpo si mexɔ dzo o ƒe daimɔnd ƒe anyigba ŋue nye 15nm, eye wòna nyatakaka tso passivation layer ƒe wɔwɔme kple eƒe titrime ŋu. Tsitretsitsi ɖe xɔxlɔ̃ ŋu kple bubuawo.

Le gɔmesesea nu la, chromium kple nickel sɔ gbɔ ɖe austenitic gakpo si mexɔ dzo o me, eye molybdenum, titanium, kple bubuawo le ɖewo me, eye zi geɖe la, chromium ƒe 10.5% alo esi wu nenema le eme eye wòtsia tre ɖe xɔxlɔ̃ ŋu nyuie.

Wowɔa passivation layer le oxidation-reduction reaction process si me wowɔa chromium kple iron oxidized le la me. Ne passivation layer gblẽ la, passivation layer yeye aɖe ava kaba eye electrochemical corrosion adzɔ enumake, eye gakpo siwo mexɔ dzo o ƒe teƒe goglowo adze. Nusiwo gblẽa nu le ame ŋu kple domenyinyi ƒe xɔdzowo ƒe xɔxlɔ̃. Passivation corrosion resistance do ƒome kple atike ƒe akpa siwo le gakpo si mexɔ dzo o me ƒe agbɔsɔsɔ, abe chromium si sɔ gbɔ, nickel kple molybdenum, kple bubuawo ene ate ŋu adzi passivation layer ƒe binding energy ŋutete ɖe edzi, eye wòana passivation layer ƒe xɔxlɔ̃ ƒe tsitretsitsi nanyo ɖe edzi; eye nàzãe kple gakpo si mexɔ dzo o ƒe pɔmpia ƒe akpa si le eme.
