Ultra Corrosion Resistant Qib 2 Titanium Rods

 

Ultra Corrosion Resistant Qib 2 Titanium Rods yog kev lag luam ntshiab titanium (CP titanium) thiab belongs rau - hom tsis yog - alloy titanium qeb. Nws yog qhov siv dav tshaj plaws thiab siab tshaj - qib ntim ntawm plaub qib ntawm kev lag luam ntshiab titanium (GR1-GR4). Vim tias nws ua rau qhov zoo tshaj qhov sib npaug ntawm lub zog, ductility, corrosion resistance, thiab nqi, nws yog lub npe hu ua "general-} hom phiaj" qib ntawm ntshiab titanium.

• Daim ntawv: Kub-khoov bar, forged tuav, tig tuav, hauv av tuav;
• Txoj kab uas hla: Feem ntau Φ1 txog Φ300 mm (qhov loj dua muaj nyob ntawm forging);
• Ntev: Feem ntau 50-6,000 mm; kev cai ntev muaj;
• Tus me nyuam mob: Annealed (M), nrog nto tiav raws li daim tawv nqaij dub, tig, los yog hauv av;
• Cov ntaub ntawv zoo: Kev yuav khoom raug cai yuav tsum muaj nrog Daim Ntawv Pov Thawj Khoom Siv (MTC); Kev kuaj ultrasonic tej zaum yuav xav tau rau cov ntawv thov tseem ceeb.

 

 

Lub corrosion kuj ntawm GR2 stems los ntawm ib tug tuab TiO₂ passivation txheej (1.5-10 nm tuab) uas tsim spontaneously ntawm nws nto; txheej no muaj nws tus kheej- kho cov khoom-ib zaug kho tshuab khawb, nws rov tsim dua tam sim hauv cov pa oxygen- muaj ib puag ncig. Qhov no yog qhov laj thawj tseem ceeb vim li cas titanium nthuav tawm qhov zoo tshaj plaws corrosion tsis kam rau stainless hlau.

Haum rau Corrosive Environments: Seawater thiab chloride ib puag ncig

Media	Cov xwm txheej	Corrosion Rate	Saib xyuas
Ntuj dej hiav txwv	Tag nrho immersion, chav tsev kub	Tsawg dua lossis sib npaug li 0.001 mm / a	Ua tiav corrosion-resistant; superior rau 316L thiab tooj liab-nickel alloys
Dej hiav txwv	110℃hauv qab no	Tsawg dua lossis sib npaug li 0.001 mm / a	Ua haujlwm rau crevice corrosion (dhau ASTM G48 Txoj Kev D)
Dej hiav txwv	Flow tus nqi 0-30m / s	Tsis yog -corrosive	Resistant rau erosion; tsis muaj cavitation corrosion tshwm sim
Dej ntsev (NaCl)	Saturated daws, boiling	< 0.025 mm/a	Ua tiav corrosion-resistant
Dej hiav txwv thiab Atmosphere	Ntev - raug raug	Tsis pom corrosion	Tsuas yog me ntsis discoloration ntawm qhov chaw

 

GR2 yog cov khoom ntawm kev xaiv rau cov khoom siv hluav taws xob sib txawv ntawm cov khoom siv sab nrauv, cov khoom siv desalination, thiab shipboard condensers. Nws cov corrosion kuj nyob rau hauv dej hiav txwv deb tshaj li ntawm 304/316 stainless hlau, thiab nws tsis raug rau pitting thiab crevice corrosion feem ntau txuam nrog stainless hlau.

GR2 pom zoo corrosion kuj nyob rau hauv oxidizing acids thiab nruab nrab / alkaline xov xwm; Txawm li cas los xij, nws cov corrosion kuj nyob rau hauv uas tsis yog - oxidizing, txo cov kua qaub (hydrochloric acid, dilute sulfuric acid, phosphoric acid) yog txwv, thiab nce kub thiab concentration yuav ua rau lub puas ntawm cov zaj duab xis passivation. Rau kev txo cov kua qaub ib puag ncig, corrosion-cov hlau tiv taus xws li GR7 (Ti-0.15Pd) lossis GR12 (Ti-0.3Mo-0.8Ni) yuav tsum raug xaiv.

- Crevice corrosion: GR2 is resistant to crevice corrosion in seawater at room temperature, but crevice corrosion may occur in high-temperature chlorinated water at temperatures >110 degree. Thaum lub sij hawm tsim, yuav tsum tau zam cov qauv tsim, lossis GR7 / GR12 yuav tsum tau siv
- Galvanic corrosion: Titanium muaj peev xwm zoo tshaj plaws hauv kev tshaj tawm feem ntau; thaum nyob rau hauv kev sib cuag nrog lwm yam hlau, nws ua raws li ib tug cathode thiab tiv thaiv, yog li nws tsis corrode. Txawm li cas los xij, nws ua kom lub zog corrosion ntawm aluminium, zinc, thiab carbon steel uas nws los rau hauv kev sib cuag, yog li insulating gaskets yuav tsum tau siv.
