Khoom Txheej Txheem

Peb cov qauv corrosion-resistant ntshiab cov ntawv kho cov hlau ua kom zoo dua qub, sib txuas ntawm cov pa hluav taws xob siab rau cov roj carbon ntau thiab stainless alloys. Tsim los rau kev lag luam xws li kev ua yeeb yam, ua haujlwm txuas ntxiv, cov ntawv sau txuas ntxiv mus rau oxidation, pitting, thiab kev nyuaj siab corrosion tawg (SCC).

Qhov tseem ceeb muaj pes tsawg leeg & cov khoom siv zoo

1. Ultra-siab purity:

- Cov ntsiab lus hlau: ntau dua lossis sib npaug nrog 99.95% FE, txo cov kab mob tsis zoo (C<0.005%, S/P <0.003%) that accelerate corrosion.

- Lw cov ntsiab lus: tswj xyuas cov hauv ntiaj teb tsis tshua muaj (piv txwv li, LA, CE<0.01%) refine grain boundaries and inhibit intergranular attack.

2. Nto Engineering:

- Ai-optimized oxide txheej: ib tug tswv yim profocemical passivation txheej txheem ua ib txheej sib txawv, tuab: 20-50 nm), txhim kho kev tiv thaiv kev tiv thaiv ntawm cov av noo lossis acidic.

- Nanocrystalline Coating: Optional plasma-sprayed Al₂O₃ or Cr₂O₃ coatings (adhesion strength >50 MPa) rau qhov ib puag ncig huab zoo li cov tub rog lossis cov chaw kub.

3. Microstration Dractory tsim:

- Lis Colinal Engineorineering

- Hydrogen embrittlement Kuj:<1 ppm dissolved hydrogen, validated via thermal desorption spectroscopy (TDS).

Cov Cuab Nruab Nruab Nruab Nruab Nruab Nruab Nruab

1. Passive zaj duab xis tsim:

- Cov hlau loj-huv siab loj sai sai, cov roj chromium-dawb oxide txheej hauv cov pa oxygenated, tiv thaiv kom tiv thaiv oxidation ntxiv.

- Tsis zoo li stainless hlau uas tau nce siab ntawm chromium, peb cov ntawv nyeem kom tsis txhob muaj kev pheej hmoo ntawm cov ciaj ciam av, hom tsis muaj ua tiav hauv Chloride-nplua nuj chaw.

2. Electrochemical stability:

- Cov kev ua haujlwm qis galvanic: homogeneous microotructure minimizes cov khub niam txiv me, txo pitting muaj peev xwm ntawm 40% piv rau cov hlau roj carbon tsawg.

- Ph phaptability: tswj kev txhim kho corrosion tsis hla muaj ntau yam ntau (3-11), zoo tagnrho rau kev tso tsheb hlau luam thiab desalination tshuab.

3. Kev ntxhov siab corrosion cracking (SCC) Mitigation:

- Muaj Kev Nyuaj Siab<50 MPa post-rolling, combined with ultra-low sulfur, eliminates crack initiation sites in high-stress applications.
