Yog Gr 2 nyob rau hauv siab - kub thiab siab - dej siab

Yog lawm, Qib 2 kev lag luam ntshiab titanium nthuav tawm cov kev tiv thaiv corrosion zoo heev hauv siab - kub thiab siab - dej siab, ua rau nws yog ib qho ntawm cov khoom siv hlau siv ntau tshaj plaws rau cov cheeb tsam no.

Grade 2 titanium forms a dense, strongly adherent TiO₂ passive film on its surface. Cov oxide txheej no ruaj khov heev hauv cov dej ntshiab, dej deionized, thiab cov dej alkaline me ntsis txawm tias qhov kub thiab txias siab, tiv thaiv corrosion ntawm titanium matrix.

Nyob rau hauv siab -kub thiab siab - cov tshuab dej siab xws li cov chaw tsim hluav taws xob, cov khoom siv hluav taws xob, thiab dej hiav txwv desalination:

Nws qhia tau hais tias yuav luag tsis muaj kev xeb dav dav;

Nws tiv taus pitting corrosion, crevice corrosion, thiab kev nyuaj siab corrosion cracking (SCC);

Nws tus nqi corrosion yog tsawg heev, feem ntau tsawg dua 0.025 mm / xyoo, txawm tias nyob rau hauv lub sijhawm ntev - kev pabcuam.

Qib 2 ua tau zoo nyob rau hauv siab - dej kub txog li 300℃, uas npog feem ntau cov pa kev lag luam siab - kub thiab siab - dej siab.

Nyob rau ntawm qhov kub thiab txias tshaj qhov no, tus nqi corrosion tseem qis, tab sis cov zaj duab xis passive yuav maj mam thicken, uas yog feem ntau siv tau rau kev siv engineering.

Piv nrog cov hlau tsis muaj steel, tooj liab alloys, thiab carbon hlau, Qib 2 titanium yog qhov zoo tshaj nyob rau hauv siab - kub siab - dej siab, tshwj xeeb tshaj yog nyob rau hauv chloride ions. Nws tsis raug kev txom nyem los ntawm cov tshuaj chloride-induced SCC, uas yog hom tsis ua hauj lwm rau stainless hlau.

Qib 2 titanium yog corrosion heev-tiv taus hauv siab- kub thiab siab - dej siab. Nws muaj kev ruaj ntseg zoo, tus nqi qis dua, thiab muaj zog tiv thaiv rau ntau hom kev xeb, ua rau nws nyiam cov khoom siv rau siab -kub dej ib puag ncig xws li lub zog tsim hluav taws xob, khoom siv hluav taws xob hloov hluav taws xob, thiab kev tsim hluav taws xob hauv hiav txwv.
