Corrosion resistance cov yam ntxwv ntawm Nickel -} Raws alloy cov ntaub ntawv

Lub corrosion tsis kam ntawm nibel - Raws li cov txawv txav raws li lawv cov khoom nruab nrab lawv tau siv nyob rau hauv.

1.Pauv npe menyuam yaus (Nickel 201 / Nickel 200)
Cov Ntawv Thov:
Tiv taus rau alkaline media (xws li sodium hydroxide);
Tiv taus nruab nrab lossis tsis muaj zog kua qaub ntsev tov, dej tshiab, dej hiav txwv;
Tsis tiv thaiv muaj zog oxidizing acids (xws li muaj cov sulfuric acid, nitric acid).
Corrosion qib: hauv ib puag ncig me me, nws yog "zoo heev" (xeb tus nqi <0.1 millimeters ib xyoos).

2. Npib {-} tooj liab alloy (monel 400 / monel K-500)
Cov Ntawv Thov:
Tiv taus dej hiav txwv, hydrofluoric acid, phosphoric acid, organic acids;
Tiv taus chloride kev ntxhov siab corrosion (zoo dua li stainless hlau);
Tsis muaj kev tiv thaiv cov oxidizing ib puag ncig thiab siab -} hydrogen sulfide.
Corrosion qib: "Zoo heev" (heev corrosion tsawg) hauv marine thiab tshuaj ib puag ncig.

3. Npib - chromium alloy (inconel 600 / inconel 600 / Inconel 625)
Cov Ntawv Thov:
Resistant rau siab - kub oxidation, nitric acid, organic acids, thiab cov tshuaj pleev xim yeeb yam kev ntxhov siab.
Haum rau kev hloov oxidizing - kev txo qhov chaw ib puag ncig.
Corrosion qib: "Zoo heev" nyob rau hauv high - kub thiab tawv nqaij ib puag ncig (corrosion tus nqi <0.05 mm / xyoo).

4. Nickel - molybdenum alloy (haastelloy b / hastelloy B-2)
Cov Ntawv Thov:
Tiv taus hydrochloric acid, sulfuric acid, phosphoric acid, thiab lwm yam (tsis {{1 oxidizing acids);
Tsis txhob tawm tsam cov xov xwm uas muaj oxidants (xws li Fe³⁺, Cu²⁺).
Corrosion qib: "Zoo heev" hauv kev txo cov kua qaub (yuav luag tsis muaj xeb)

5. Npib - chromium - molybdenum alloy (haastelloy C-276 / C-22)
Cov Ntawv Thov:
Resistant rau oxidizing acids (nitric acid, sib xyaw acid), chloride, thiab dej noo noo;
Muaj zog heev tsis kam rau pitting thiab crevice corrosion.
Corrosion qib: "Sab saum toj" nyob rau hauv cov khoom sib xyaw thiab cov chaw muaj zog (corrosion tus nqi tuaj yeem tsis quav ntsej)

Qhov kev siv tau tiag tiag yuav tsum raug ntsuas raws li ib puag ncig, ntsuas kub, cov khoom lag luam thiab oxidation {{0} {kev ua haujlwm txo;
Nyob rau hauv ib puag ncig nrog cov leej faj lossis kev ntxhov siab ntau, tsim qauv tshwj xeeb yog tseev kom muaj (xws li ntxiv tungsten, tooj liab, thiab lwm yam);
Yog tias koj xav kom pom zoo nickel - Raws li cov chaw ib puag ncig, xws li Ecycomation Ec- Kev txo cov khoom ua tau zoo, oons.
