Titanium, kev ua haujlwm siab hlau, kev nthuav tawm cov kev daws teeb meem zoo nkauj ntawm cov hlau tsis muaj zog ntxiv rau hauv cov khoom siv hauv titanium nyob rau hauv titanium khoom yog nyob rau sawv.
Pitting corrosion nyob rau hauv titanium yog tsawg dua tshwm sim piv rau cov kab mob sib kis, nrog rau cov chaw nyob hauv zos .
Cov kev qhia hauv tshuab hluav taws xob tuaj yeem txiav txim siab rau cov pitting corrosion ntawm cov hlau, kev txhawb nqa lawv cov kev ntxim nyiam rau pitting corrosion .
Yam cuam tshuam rau titanium pitting corrosion
Rhiab heev nce nrog qhov kub hauv chloride lossis bromide daws .
pH muaj qhov cuam tshuam me me rau titanium tus pitting distortance .
Hauv kev daws teeb meem chloride, titanium lub peev xwm tshwm sim yog kwv yees li ntawm bromide lossis cov kev daws teeb meem qis dua, ua kom muaj kev sib cav sib ceg {}}
Cawv ntawm cov ntsiab lus hlau
Cov cov ntsiab lus hlau cov ntsiab lus txo cov titanium qhov tsis kam rau pitting corrosion, nrog Ti-Faib ntau dua li pitting caposion .
Deg ua ntej kho mob
Nqus Annealing thiab Anodization Txhim Kho Titanium tus pitting corrosion muaj peev xwm, txo cov kev ua tau zoo .
Ntub ntub cov av xuab zeb polishing tsub qhov ua kom zoo li ntawm pitting corrosion .
Lwm Yam
Nto roughness thiab tiv tauj nrog qee yam hlau zoo li zinc, hlau, manger txhawb pitting pitt corrosion .
Tej yam anion xws li sulfate, nitrate, chromate, phosphate, thiab carbonate ions txhim kho titanium kev tiv thaiv mus rau pitting corrosion .
Cov theem kev loj hlob ntawm pitting corrosion
Pitting corrosion feem ntau nce zuj zus mus los ntawm nucleation, kev loj hlob, thiab phais nplooj .
Nucleation tshwm sim thaum lub peev xwm ntawm titanium surpasses lub peev xwm tawg tau ntawm cov yeeb yaj kiab oxide .
Kev loj hlob muaj feem koom nrog lub ntsuas pom ntawm corrosion pits rau lub sij hawm .
Repassivation tuaj yeem nres kev txhim kho corrosion, qee zaum tiv thaiv kev ua kom tiav rau theem passive thiab zoo tso tseg qhov kev loj hlob .
