Corrosion kev tiv thaiv yog hais txog qee yam kev tiv thaiv tiv thaiv sib txawv los tiv thaiv cov tshuaj sib txawv los tiv thaiv cov khoom siv thiab cov khoom los ntawm kev puas tsuaj los ntawm kev siv tshuaj corrosion. Hauv kev tsim khoom lag luam, ntau cov kua tshuaj muaj ntau yam yog cov khoom siv ua kom zoo, yog li tiv thaiv kev tiv thaiv corrosion yuav tsum tau coj los tiv thaiv cov khoom siv. Raws li ib qho zoo tshaj plaws corrosion-resistant cov ntaub ntawv, titanium yog siv dav hauv kev tsim khoom ntawm cov khoom siv tshuaj lom neeg, cov cuab yeej siv marine, aerospace thiab lwm thaj teb. Kev corrosiveness ntawm titanium cov ntaub ntawv sib txawv nrog cov kua acidic thiab alkaline kua, yog li ntawd, xaiv cov khoom siv ntawm cov kua sib txawv. Hauv qab no, peb yuav qhia ntau hom acidic thiab alkaline kua, thiab cov hom titanium uas yuav tsum tau siv.
Cov kua kua qaub yog hais txog cov kua nrog tus nqi pH tsawg dua 7, uas tau muaj zog corrosiveness rau hlau thiab tooj. Titanium cov khoom muaj cov kua qaub tsis zoo thiab tuaj yeem tiv taus corrosion los ntawm ntau cov kua acidic. Cov kua ntau acidic muaj cov kev xaiv sib txawv rau cov khoom siv titanium. Cov hauv qab no yog ob peb cov kua dej acidic: (1) nitric acid. Nitric acid yog cov tshuaj oxidant muaj zog uas tuaj yeem ua rau corrosion nyob rau hauv cov ntaub ntawv hlau feem ntau. Txawm li cas los xij, Titanium cov khoom muaj zog corrosion tsis muaj zog rau nitric acid thiab tuaj yeem kho nrog ntshiab titanium lossis ti {}}. 8ni alloy rau kev tiv thaiv corrosion. Ntawm lawv, ti -0. 3mo}. 3Ni}. 8NI}. 8NI}. 8Ni Siv Hauv Cov Khoom Siv Ntau Lawm. (2) sulfuric acid yog cov kua tshuaj acidic uas muaj corrodes cov ntaub ntawv feem ntau. Txawm li cas los xij, Titanium cov ntaub ntawv muaj zoo corrosion tsis kam rau cov sulfuric acid, yog li ntshiab titanium lossis ti {13}}. 8Ni}. 8Ni}. 8Ni}. (3) Hydrochloric acid yog cov kua qaub inorganic acid uas yog cov khoom kom haum rau ntau cov ntaub ntawv metallic. Txawm li cas los xij, Titanium cov ntaub ntawv muaj zoo corrosion tsis kam rau hydrochloric acid, yog li ntshiab titanium lossis ti {16}}. 8Ni}.
Alkaline kua rau hais txog cov kua nrog tus nqi pH ntau dua 7, uas tuaj yeem corrode ntau cov ntaub ntawv hlau. Cov kua txiv alkaline txawv muaj sib txawv corrosiveness ntawm titanium cov ntaub ntawv. Cov hauv qab no yog ntau cov kua alkaline ntau: (1) sodium hydrocide yog cov kua muaj zog alkaline yog siv rau kev ntxuav thiab corroding hlau chaw. Titanium cov ntaub ntawv muaj zoo corrosion tsis kam rau sodium hydroxide thiab feem ntau ua los ntawm ntshiab titanium lossis ti {}}}. 8ni alloy. (2) poov tshuaj hydroxide tseem yog cov kua muaj zog alkaline nrog kev ua kom muaj zog. Hauv kev sib piv, titanium cov ntaub ntawv muaj cov tshuaj tsis zoo rau cov poov tshuaj hydroxide, yog li ti {}}. 8ni alloy feem ntau siv rau kev tsim khoom. (3) Cov khoom siv titanium nyob rau hauv cyanide tov feem ntau muaj qhov muaj zog heev thiab corrosiveness, yog li nws yog qhov tsim tittiium siv rau kev kho mob corrosion. Hauv cov kev daws teeb meem, feem ntau siv cov khoom siv titanium suav nrog TA1, TA2, thiab lwm yam, uas tuaj yeem tiv thaiv kev xeb hauv cov kev daws teeb meem cyanide.
Hauv ntej, cov khoom siv titanium yog ib qho khoom siv txhim kho dav-resistant dav siv nyob rau hauv ntau daim teb zoo li cov khoom siv tshuaj lom neeg, khoom siv kho mob, thiab cov khoom siv kho mob, thiab cov khoom siv kho mob, thiab marine engineering. Thaum xaiv cov khoom siv titanium, nws yog ib qho tsim nyog los xaiv hom uas tsim nyog ntawm titanium khoom raws li cov yam ntxwv sib txawv los ua haujlwm ntev ntawm cov khoom siv.
