Ferro Niobium Corrosion Resistance

Ferroniobium yog ib qho khoom siv superalloy, uas muaj qhov zoo corrosion kuj nyob rau hauv qhov kub thiab txias thiab muaj zog corrosion tej yam kev mob.Lub ntsiab yog vim li cas niobium hlau muaj cov nram qab no zoo.

Kev piav qhia

Ferroniobium tuaj yeem tsim cov yeeb yaj kiab tuab ntawm cov pa roj oxygen, yog li ua si ib tug zoo heev orrosion anti-corrosion effections.in ntxiv, niobium oxide hauv niobium hlau oxide zaj duab xis kuj tuaj yeem tsim cov txheej txheem ruaj khov nrog rau saum npoo ntawm niobium hlau oxide zaj duab xis, ua rau kev ruaj ntseg ntawm oxide zaj duab xis muaj zog.

Niobium hlau tuaj yeem tiv taus ntau lub zog acid corrosion, xws li hydrofluoric acid, nitric acid, sulfuric acid, thiab lwm yam.

Qhov no yog vim hais tias cov oxide zaj duab xis nyob rau saum npoo ntawm hlau niobium tuaj yeem tiv thaiv kev yaig ntawm cov kua qaub tawm, thiab cov niobium hauv cov hlau niobium kuj tuaj yeem tsim qee cov tshuaj ruaj khov nrog qee cov kua qaub tawm, yog li ua si zoo heev los tiv thaiv corrosion.

Ferro Niobium Corrosion Resistance

Niobium hlau tuaj yeem tiv taus ntau alkali corrosion, xws li potassium hydroxide, sodium hydroxide, thiab lwm yam.

Qhov no yog vim hais tias oxide zaj duab xis nyob rau saum npoo ntawm hlau niobium tuaj yeem tiv thaiv kev yaig ntawm alkaline xov xwm, thiab niobium keeb hauv hlau niobium kuj tuaj yeem tsim qee qhov sib txuas ruaj khov nrog qee cov xov xwm alkaline, yog li ua si zoo heev los tiv thaiv corrosion.
