Piting Corrosion inonziwo diki yegomba regomba, pirting kana pamba.
Iyo fomu yekukuvara kwekukanganisa mune iyo yakawanda yezvikamu zveMetal anoitaKwete corrode kana corrodes zvishoma, asi maburi eora anoonekwa munzvimbo dzemunharaunda uye akura zvakadzama. Mamwe maMiti aripo mukuzviparadzanisa nevamwe, nepo vamwe vacho vakabatana uye vanotaridzika kunge nzvimbo yakaoma. Etch mabhegi anogona kunge ari makuru kana mashoma, asi anowanzove zvidiki, sezvakaratidzwa mumufananidzo uyu wakasiyana-siyana Pfungwa ndeimwe yemapatani anokuvadza zvakanyanya eDuplex Stainless Simbi. Pamba pamba kazhinji kazhinji nzvimbo yekutanga yekumanikidza corrosion cracks uye corrosion inonamira marara.
Simbi isina nguraSpecial Passivation firimu nekuda kwekuvapo kwekuremara muStule Simbi, iyo Inzvimbo Yekupararira inova isingaiti kukwidziridzwa, uye wobva waita akati wandei emakomba emakomba.
Simbi isina simbi, pamwe nedzimwe simbi dzinovimbaPassivationKuti udzorere kupokana, mune mhinduro ine chaiyo anon (chloride, bromide, hypochlorite, kana thosulfate ion). Chero bedzi iyo corrosion inogona (kana inogona kushandiswa panguva yeAnodic Polarization) inodarika iyo yekuisa iyo inogona kuita EB, pombi inogona kuitika. Iyo Mechanism yePleting Corrosion yeDuplex Stainless Simbi yakafanana nedzimwe stainless simbi.
Simbi yakarapwaNezve oxiding media, huwandu hwayo hwekuita kupfuura hwaro hwepakutanga husati hwadzikira kusati kwaderera muzvisuzhinji zvinozivikanwa sesimbi simbi. Iyo Spassivation Mechanism inogona kunyanya kushandiswa kutsanangura iyo yakaonda firimu dzidziso, kurevaPassivationinokonzerwa nebasa resimbi uye oxiding media, basa resimbi kuti riite mutete mutete, wekuvhara, unokwanisa kusungirirwa zvakanyanya kune iyo simbi yepasi pevhu firimu. Iyi firimu mune chikamu chakaparadzana iripo, kazhinji okisijeni uye mesimbi mishonga. Iyo inotora basa resimbi uye rezvenhau dzakaparadzaniswa zvachose nebasa rekudzivirira simbi uye nedhisheni yekubata zvakananga, kuti simbi yakamira ichinyungudika kuumba mamiriro ekudzivirira.
