Titaniumexhibits excellent corrosion resistance in both river and seawater, with its resistance in seawater being particularly valuable. It is no exaggeration to say that titanium is the most corrosion-resistant metal material in all natural waters. Titanium may discolor or lose its luster in high-temperature water and steam (e.g., >300 degree), thiab tej zaum yuav nce me ntsis qhov hnyav, tab sis qhov no yuav tsis ua rau corrosion.
Titanium yog corrosion kuj heev -resistant nyob rau hauv seawater ntawm qhov kub thiab txias li 260℃. Titanium tube condensers tau siv nyob rau hauv cov dej hiav txwv muaj kuab paug rau ntau tshaj 20 xyoo nrog tsuas yog me ntsis discoloration thiab tsis muaj cov cim ntawm corrosion. Vim tias titanium tsis yog corrosive los yog tshuaj lom nyob rau hauv seawater, marine organism attachment yog ib qho teeb meem tseem ceeb. Kev lag luam ntshiab titanium nthuav tawm qhov zoo tshaj plaws tiv thaiv corrosion, pitting corrosion, thiab cuam tshuam corrosion nyob rau hauv seawater, thiab nws susceptibility rau kev nyuaj siab corrosion thiab corrosion qaug zog yog tsis hnyav. Hauv siab - nrawm ntws dej hiav txwv (piv txwv li, 36.6 m / s), qhov kev yaig kuj nce me ntsis. Lub xub ntiag ntawm cov khoom abrasive xws li cov xuab zeb hauv dej hiav txwv muaj qee qhov cuam tshuam rau titanium qhov kev yaig, tab sis tsis hnyav li ntawm tooj liab thiab txhuas alloys. Hauv dej hiav txwv, titanium kuj yog cov khoom siv zoo tshaj plaws rau kev tiv thaiv cavitation corrosion.
1. Marine ib puag ncig:
Tsis tshua muaj zog corrosion kuj: Titanium tsis kam rau seawater corrosion yog 100 npaug ntawm stainless hlau, nrog zoo tsis muaj pitting, crevice corrosion, los yog uniform corrosion. Nws cov yeeb yaj kiab oxide nto yog tus kheej - kho thiab tuaj yeem rov tsim dua sai dua txawm tias puas.
High-temperature adaptability: Remains stable in seawater below 260℃, but strong acidic environments with pH=1 or high temperatures (>300 degree) tuaj yeem cuam tshuam kev ua haujlwm.
Daim ntaub ntawv: Dav siv nyob rau hauv seawater desalination khoom, offshore platform structural Cheebtsam, thiab lwm yam.
2. Dej dej ib puag ncig
Kev ruaj ntseg siab: Titanium pom zoo corrosion kuj nyob rau hauv dej tshiab (xws li dej dej), thiab nws cov oxide zaj duab xis zoo tiv thaiv corrosion los ntawm qaug zog acidic los yog alkaline xov xwm.
Qhov zoo sib piv: Piv nrog rau cov dej hiav txwv, cov dej hauv dej tsis tshua muaj corrosive, ua rau titanium txhim khu kev qha rau ntev - siv.
Lub hauv paus ntsiab lus ntawm Corrosion Resistance: Lub ntuj tsim ntom ntom oxide zaj duab xis (TiO₂) ntawm titanium nto yog qhov tseem ceeb rau kev tiv thaiv corrosion. Nws qhov P/B piv (1 ~ 2.5) ua kom tiav kev pab cuam ntawm substrate thiab nws tus kheej - kho.
