Zoo heev tiv thaiv corrosion los ntawm kev txo cov acids
Lub ntsiab kom zoo dua ntawm Gr7 (TA9) nyob rau hauv qhov sib ntxiv ntawm palladium. Taw qhia 0.12%–0.25% palladium (Pd) rau hauv kev lag luam ntshiab titanium (Gr2) ua kom nws cov corrosion kuj hauv kev txo cov kua qaub tawm. Hauv cov uas tsis yog -oxidizing acids xws li hydrochloric acid (HCl), sulfuric acid (H₂SO₄), formic acid, oxalic acid, thiab citric acid, tus nqi corrosion ntawm Gr7 yog qis dua li ntawm kev lag luam ntshiab titanium. Nws tuaj yeem hloov tau ntau dua zirconium los yog npib tsib xee-raws li alloys nyob rau hauv tej yam concentration thiab kub tej yam kev mob. Cov cuab yeej no ua rau nws yog ib qho khoom siv zoo tshaj plaws rau kev tuav cov xov xwm corrosive hauv kev lag luam xws li chemical engineering, pharmaceuticals, thiab hydrometallurgy.
Kev tiv thaiv zoo heev rau crevice corrosion thiab pitting corrosion
Gr7 (TA9) muaj kev tiv thaiv zoo heev rau kev xeb thiab pitting nyob rau hauv siab -kub tshuaj chloride xws li dej hiav txwv, brine, thiab dej brackish. Qhov sib ntxiv ntawm palladium txo qis titanium lub peev xwm passivation nyob rau hauv chloride media, tso cai rau cov khoom kom muaj kev ruaj ntseg passive lub xeev txawm nyob rau hauv siab - kub, siab - chloride ib puag ncig. Cov cuab yeej no ua rau nws qhov kev xaiv tsis tuaj yeem hloov pauv rau cov ntawv thov ntev ntev rau cov xov xwm corrosive, nrog rau cov khoom siv desalination, chlor-alkali kev lag luam txheej txheem, thiab marine engineering tshav kub exchangers.
Zoo machining thiab vuam zog
Gr7 (TA9) khaws cov khoom txias thiab kub ua haujlwm zoo thiab kev ua haujlwm vuam ntawm kev lag luam ntshiab titanium. Nws tuaj yeem dhau los ua cov txheej txheem xws li forging, dov, stamping, thiab dabtsi yog khoov, thiab tuaj yeem welded siv ntau txoj hauv kev xws li TIG (Tungsten Inert Gas) vuam, MIG (Hlau Inert Gas) vuam, plasma vuam, electron beam vuam, thiab welding kuj. Qhov kev tiv thaiv corrosion ntawm cov welded sib koom ua ke yog ib txwm ua raws li cov khoom siv hauv paus. Nws yog qhov tsim nyog rau kev tsim cov txheej txheem corrosion-cov cuab yeej tiv taus thiab cov ntim tshuaj loj.
Ntev -lub sijhawm ua haujlwm ruaj khov
Gr7 (TA9) nthuav tawm qhov kev txhim kho corrosion siab heev nyob rau hauv qhov hnyav corrosive ib puag ncig, cuam tshuam cov cuab yeej siv lub neej thiab txo kev tu thiab hloov zaus. Hauv kev lag luam xws li kev ua tshuaj lom neeg, dej hiav txwv desalination, thiab tshuaj, kev poob qis los ntawm cov khoom siv tsis ua haujlwm vim corrosion feem ntau tshaj tus nqi ntawm cov ntaub ntawv lawv tus kheej. Gr7 muab cov neeg siv khoom nrog ntev - lub sij hawm ruaj khov ruaj khov ntawm tus nqi qis dua tag nrho lub neej.
