Electrochemical corrosion thiab kev tiv thaiv ntawm cov ceev zog tshuab
Ⅰhat yog cov corrosion tawm tsam sib txawv ntawm zinc-nickel ally plating thiab kub-dip galvanizing?
Zinc-Nickel Alloy plating ({% Nickel), ua rau nws muaj xeb liab - rau galvanizing-resistant {}}} ho 30% tus nqi, nws foob cov chaw hnyav uas zoo li cov kab ke hla (E64 16}}}}}}
Ⅱhat yog xaiv lub hauv paus rau 304 vs 316 stainless hlau elastic clips?
304 stainless steel (8% nickel) resists corrosion better than carbon steel, suitable for humid areas (e.g., southern coasts), but rusts when Cl⁻ >200PPM {. 316} backing hlau (2% Molybdenum (2 {}}
Of Txoj kev tiv thaiv kab mob "yog li cas?
Cov qauv no teeb cov zinc blocks (-1.1 v muaj peev xwm los tiv thaiv steel faster, thiab hloov chaw 5} Qhov no txo corrosion los ntawm 80% tab sis ntxiv ~ ¥ 5 / m nyob rau hauv cov nqi .
Ⅳ Vim li cas dacromet-coated bolts yuav tsum tau kho kev kho mob?
Dacromet txheej muaj nanoscale lub hws uas nqus noo noo thaum 500 teev}}} xav tau ¥ 80, {{{}}} hauv cov nqi pabcuam ntxiv rau rov ua dua .
Ⅴthow yog "micro-roj teeb kev cuam tshuam" ntawm electrochemical corrosion manifest hauv cov tshuab ceev ceev?
Thaum ib qho elastic clip (60si2mn steel, {v txhu muaj cov tshuaj corrosion (304 steel ② Siv cov ntaub ntawv uniform (tag nrho cov pa hlau lossis txhua cov hlau stainless); ③ Cadmium-phaj clips ({nplooj ntoos} v muaj peev xwm txo qhov muaj peev xwm txo qhov sib txawv ntawm cov hlau).
