Kev sib piv ntawm Chloride Tsis kam ntawm Cov Ntshiab Titanium thiab Titanium-Palladium Alloy
Qhov salinity ntawm seawater feem ntau yog tsawg dua li 5%. Raws li kev sim ntev thiab kev siv tiag tiag, tau txiav txim siab tias cov ntshiab titanium tuaj yeem siv tau huv hauv dej hiav txwv hauv qab 120 degrees, tab sis kev tsim xeb tuaj yeem tshwm sim yog tias qhov kub nce dua, pitting corrosion yuav tshwm sim yog tias nws txuas ntxiv .Qhov kev siv ntau ntawm titanium nyob rau hauv ntau qhov sib txawv, tus nqi Ph (3-9), qhov ntsuas kub hauv NaCl tov yog qhia hauv daim duab hauv qab no.
Ntxiv mus, Qib 7 Titanium Alloy (Ti-0. 2 Pd, Qib 7) thiab titanium-nickel-molybdenum alloy (Ti-Qib-1 2) tuaj yeem tau siv hauv qhov kub-pressurized dej hiav txwv ntawm 2 60 qib! Hauv qab no yog qhov siab tshaj qhov kub tshaj plaws ntawm cov ntshiab titanium, Ti Pd alloy (Qeb 7), titanium-nickel-molybdenum alloy (Qib 1 2) nyob rau hauv ntau qhov sib txawv ntawm magnesium chloride tov, sodium chloride tov, calcium chloride tov, dhau ntawm qhov kev txwv no, nws yuav tshwm sim kev pleev xim tsis zoo los yog pitting corrosion. Nws tuaj yeem pom tau tias nyob rau hauv qhov kev ua haujlwm no, Titanium Qib 7 thiab titanium-nickel-molybdenum alloy muaj ntau tiv taus chloride ions dua li cov titanium ntshiab!
Kev tiv thaiv xeb: qib 7 > Qib 12 > Ntshiab si ntshiab si titanium (Qeb 2).
Lus Cim: Hauv daim duab, cov voj voog dawb uas lawv siv tau; lub voj voos dub dub sawv cev tiv thaiv kev tsim xeb lossis pittingcorrosion; daim duab peb sab dawb ua rau lub ntsej muag me ntsis kev xeb, tab sis tsis cuam tshuam rau siv.
Hauv MgCl 2 txoj kev hais daws
Hauv CagCl 2 tov
Hauv NaCl daws
Daim duab hauv qab no qhia txog kev siv rangeof titanium thiab nws cov alloys hauv sodium sodium chloride tov ntawm PH tus nqi sib txawv.
Nws tuaj yeem hais tias qib 7 Ti-0. 15 Pd Alloy (UNS R 52400) tsis yog tsuas yog siv los ntawm qhov kub thiab txias tab sis kuj tuaj yeem siv raws li cov kua qaub siab dua.
