Qib 12 titanium barmuaj kev tiv thaiv corrosion zoo heev hauv ntau qhov chaw nruj heev, suav nrog ob qho tib si oxidizing thiab txo qhov chaw.
Nyob rau hauv oxidizing ib puag ncig, xws li marine thiab industrial atmospheres, qib 12 titanium bar tsim ib tug passive oxide txheej ntawm nws nto uas tiv thaiv nws los ntawm ntxiv oxidation. Cov oxide txheej ruaj khov thiab ua raws, uas ua rau qib 12 titanium bar tiv taus corrosion thiab yaig los ntawm dej hiav txwv, chlorides, thiab lwm yam tshuaj lom neeg.
Hauv kev txo qis ib puag ncig, qib 12 titanium bar qhov corrosion kuj yog vim nws lub peev xwm los tsim cov txheej txheem oxide ruaj khov nyob rau hauv lub xub ntiag ntawm hydrogen, hydrogen sulfide, thiab lwm yam tshuaj txo. Cov oxide txheej tiv thaiv qib 12 titanium bar los ntawm kev xeb ntxiv thiab yaig los ntawm cov neeg ua haujlwm no.
Tsis tas li ntawd, qib 12 titanium bar qhov corrosion kuj yog txhim kho los ntawm nws cov thermal expansion coefficient thiab siab melting point, uas ua rau nws haum rau siv nyob rau hauv high-temperature thiab cryogenic daim ntaub ntawv.
Qee cov ntsiab lus ntxiv txog kev tiv thaiv corrosion ntawm qib 12 titanium bar:
1. Qib 12 titanium bar yog cov resistant rau crevice corrosion thiab stress corrosion cracking (SCC) nyob rau hauv ib puag ncig uas muaj chloride, xws li seawater thiab brines. Qhov no yog vim nws lub peev xwm los tsim ib qho kev ruaj khov passive oxide txheej uas tiv thaiv cov hlau los ntawm kev xeb hauv zos.
2. Kev tiv thaiv corrosion ntawm qib 12 titanium tuav tuaj yeem txhim kho ntxiv los ntawm kev kho saum npoo, xws li anodizing lossis tshuaj passivation. Cov kev kho mob no tsim kom muaj cov oxide tuab dua thiab ua kom zoo dua qub.
3. Qib 12 titanium bar kuj tiv taus pitting corrosion. Pitting yog ib qho chaw hauv cheeb tsam ntawm corrosion uas tuaj yeem tshwm sim thaum muaj cov tshuaj phem, xws li chlorine thiab acids. Txawm li cas los xij, qib 12 titanium bar muaj peev xwm tsim cov txheej txheem oxide ruaj khov ntawm nws qhov chaw ua rau nws tiv taus pitting.
4. Qib 12 titanium bar kuj tiv taus galvanic corrosion, uas tshwm sim thaum ob qhov sib txawv ntawm cov hlau tsis sib xws nyob rau hauv lub xub ntiag ntawm electrolyte (xws li dej ntsev). Qib 12 titanium bar qhov tsis tshua muaj peev xwm galvanic thiab siab tiv thaiv corrosion ua rau nws haum rau siv hauv bimetallic daim ntaub ntawv.
Zuag qhia tag nrho, qib 12 titanium bar qhov zoo tshaj plaws corrosion kuj ua rau nws yog ib qho khoom siv zoo heev rau kev siv nyob rau hauv ntau qhov chaw ua phem, nrog rau kev ua dej hiav txwv, tshuaj lom neeg, thiab kev lag luam roj thiab roj, thiab lwm yam.
