Tsim thiab Stabilization ntawm Passivation Zaj duab xis

 

Pib tsim ntawm Passivation Zaj duab xis: Hauv stainless hlau, chromium yog lub hauv paus tseem ceeb rau kev tsim cov yeeb yaj kiab passivation. Thaum cov hlau tsis xeb raug rau cov pa oxygen - muaj ib puag ncig, cov chromium atoms ntawm qhov chaw yuav hnov ​​​​mob nrog oxygen los ua ib tug tuab chromium oxide (Cr₂O₃) nyias zaj duab xis. Cov yeeb yaj kiab no yog nyias nyias, feem ntau tsuas yog ob peb nanometers tuab, tab sis nws tuaj yeem cais cov hlau tsis muaj steel substrate los ntawm lwm cov xov xwm corrosive xws li oxygen, dej, thiab ntau yam tshuaj.

 

Stabilizing Lub luag haujlwm ntawm Nickel: Nickel plays lub luag haujlwm hauv kev ruaj khov thiab ntxiv dag zog rau cov yeeb yaj kiab passivation hauv cov txheej txheem no. Nickel atoms tuaj yeem muab tso rau hauv cov qauv lattice ntawm chromium oxide zaj duab xis, hloov cov qauv hluav taws xob thiab cov khoom siv tshuaj lom neeg ntawm cov yeeb yaj kiab. Qhov kev koom ua ke no ua rau cov yeeb yaj kiab passivation ntau dua thiab txo qhov tsis xws luag thiab qhov pores hauv zaj duab xis. Piv txwv li, nyob rau hauv npib tsib xee - muaj 304 stainless hlau, lub xub ntiag ntawm npib tsib xee ua rau cov zaj duab xis passivation ruaj khov dua li cov nickel - dawb stainless hlau thiab zoo dua tuaj yeem tiv thaiv kev nkag mus ntawm corrosive ions xws li chloride ions.

 

Kev Kho ntawm Kev puas tsuaj Passivation Zaj duab xis: Nyob rau hauv qhov chaw ua haujlwm tiag tiag, zaj duab xis passivation tuaj yeem raug puas tsuaj hauv zos vim kev puas tsuaj rau cov khoom siv tshuaj lom neeg, tshuaj yaig, lossis lwm yam laj thawj. Lub sijhawm no, npib tsib xee tuaj yeem txhawb nqa qhov sib txawv ntawm cov ntsiab lus chromium mus rau thaj chaw puas. Vim muaj cov npib tsib xee nyob rau hauv stainless - steel matrix, nws muaj peev xwm ua raws li "nruab nrab" coj chromium atoms kom txav ceev mus rau qhov chaw puas, kom cov chromium oxide tshiab tuaj yeem rov tsim dua ntawm thaj chaw puas, kho raws sijhawm. cov yeeb yaj kiab passivation, thiab tiv thaiv kev txhim kho ntxiv ntawm corrosion.

Hloov ntawm Corrosion Potential

 

Cov Ntsiab Cai ntawm Electrochemical Principles: Los ntawm kev xav ntawm electrochemical, hlau yuav tsim cov tshuaj tiv thaiv corrosion hauv cov tshuaj electrolyte. Nyob rau hauv lub xovtooj ntawm no, cov electrode muaj peev xwm ntawm cov hlau sib txawv txiav txim siab lawv lub luag haujlwm hauv cov txheej txheem corrosion. Cov hlau uas muaj peev xwm qis dua electrode feem ntau yuav plam electrons thiab raug corroded li anodes; thaum cov hlau uas muaj qhov muaj peev xwm electrode ntau dua yog qhov nyuaj dua kom raug corroded.

 

Cov txiaj ntsig ntawm Nickel ntawm Kev Muaj Peev Xwm Loj: Qhov sib ntxiv ntawm cov npib tsib xee tuaj yeem ua rau cov electrode muaj peev xwm ntawm cov hlau tsis muaj steel, ua rau nws muaj peev xwm muaj peev xwm ntawm cov hlau tsis zoo (xws li kub thiab platinum). Nyob rau hauv stainless - hlau - electrolyte tov system, anodic tshuaj tiv thaiv kev ua si ntawm npib tsib xee - muaj stainless hlau yog txo. Piv txwv li, nyob rau hauv ib tug qauv nrog ntau yam hlau sib txuas, xws li ib tug stainless - steel yeeb nkab txuas nrog ib tug carbon - steel kev them nyiaj yug, cov pa roj carbon steel muaj ib tug qis electrode peev xwm thiab yog yooj yim corroded raws li ib tug anode. Txawm li cas los xij, vim tias muaj peev xwm ntau ntxiv ntawm npib tsib xee - muaj cov hlau tsis muaj steel, qhov sib txawv ntawm nws thiab carbon hlau raug txo, yog li txo qhov kev pheej hmoo ntawm galvanic corrosion ntawm lawv. Qhov kev hloov pauv hauv qhov muaj peev xwm ua rau cov nickel - muaj cov hlau tsis muaj steel kom zoo dua tswj nws txoj kev ncaj ncees hauv ib puag ncig electrochemical corrosion.
