1, nitric acid
Nitric kua qaub yog hom oxidizing acid, titanium hauv nitric acid, nws cov npoo tswj txoj ntswg ntawm oxide zaj duab xis. Yog li ntawd, titanium muaj zoo heev corrosion tsis zoo nyob rau hauv nitric acid. Tus nqi corrosion ntawm titanium nce nrog ntsuas kub ntawm nitric acid daws. Qhov kub nyob rau xyoo 190 ~ 240 degree, siab txog 20% ~ 70%, tus nqi xeb ntawm li 10mm / a. Tab sis nyob rau hauv nitric acid daws teeb meem me me ntawm silicone tebchaw, tuaj yeem inhibit qhov kub kub nitric acid corrosion ntawm titanium; Piv txwv li, hauv 40% ntawm qhov kub ntawm nitric acid Kev daws teeb meem ntxiv roj, cov xeb hauv corrosion tau raug txo kom muaj sib npaug rau xoom. Kuj tseem muaj cov ntaub ntawv nyob hauv qab 500 degree, titanium muaj qib siab ntawm corrosion tsis kam nyob rau hauv 40% rau 80% ntawm nitric acid daws thiab chav. Hauv fuming nitric acid, thaum muaj nitrogen dioxide nyob rau hauv ntau dua 2%, vim muaj cov tsis txaus, vim tias muaj kev tawg.
2, sulfuric acid
Sulfuric acid yog cov muaj zog txo cov kua qaub, titanium muaj qee cov degree tiv taus kub thiab qis sulfuric acid daws teeb meem. Ntawm {{{{{{4 4}}}}} degree, nws tuaj yeem tiv thaiv cov pa roj acid nrog rau 20%, thiab cov xeb ntawm cov kua qaub thiab ntsuas kub. Yog li ntawd, qhov ruaj khov ntawm titanium hauv sulfuric acid yog tsis zoo, txawm tias nyob rau hauv diam oxygen ntawm chav tsev kub, titanium tuaj yeem tiv taus 5% sulfuric acid corrosion. Ntawm 100 degree, titanium tsuas tuaj yeem tiv thaiv 0.2% sulfuric acid corrosion. Chlorine ntawm corrosion ntawm titanium hauv sulfuric acid muaj cov accegitia, tab sis ntawm 90 degree, tshwm sim los ntawm titanium corrosion nrawm, thiab txawm tias tshwm sim los ntawm hluav taws. Titanium corrosion tsis kam nyob rau hauv sulfuric acid tuaj yeem txhim kho los ntawm kev ua kua, yog li ntawd, titanium hauv sulfuric acid muaj tsawg tus nqi.
3, alkaline daws
Titanium has good corrosion resistance in most alkaline solutions, the corrosion rate increases gradually with the concentration and temperature of the solution, in the presence of oxygen, ammonia or carbon dioxide in the lye, will accelerate the corrosion of titanium, in the lye containing hydrogen oxide, titanium's corrosion resistance is very poor. Txawm li cas los xij, cov corrosion tsis kam nyob rau hauv sodium hydrocide kev daws teeb meem hydroundy thiab siab conclocide daws kuj muaj cov muaj zog corrosion. Xws li titanium ntawm 13 {{{0 degree, tiam sis yog qhov sib txawv ntawm cov khoom siv tshuaj lom neeg hydroxide Yog li no, titanium nyob rau caustic dej qab zib thiab lwm yam kev sib txuam ntawm alkaline cov kev daws teeb meem yuav tsum tau siv nyob rau hauv kub tsawg dua los yog sib npaug rau 93.33 degree.
4, Chlorine roj
Qhov kev ruaj ntseg ntawm titanium hauv cov tshuaj chlorine roj nyob ntawm cov ntsiab lus dej hauv chlorine. Txawm li cas los xij, nws tsis yog corrosion-resistant nyob rau hauv cov chaw muag tshuaj uas qhuav qhuav, thiab muaj kev phom sij ntawm kev ua rau kev sib txuas. Yog li, titanium siv nyob rau hauv cov tshuaj chlorine yuav tsum muaj cov ntsiab lus dej, hauv cov tshuaj hauv chav dej uas yuav tsum muaj nrog lub siab, ntws tawm, ntsuas kub thiab lwm yam kub thiab lwm yam cuam tshuam nrog cov tshuaj cholorine.
5,Organic Media
Titanium hauv roj av, Tolue, Phenol, Formaldehyde, acetic acid, citricoroacete acid, etc. muaj siab corrosion tsis kam. Nyob rau hauv lub boiling taw tes thiab tsis inflated, titanium nyob rau hauv 25% ntawm cov hauv qab acid yuav ua actict, hauv kev daws teeb meem, titanium tsis yog ua rau muaj kev sib cav sib ceg thiab yuav tsim cov corrosion. Rau ntau cov organic synthesis hauv kev sib cuag nrog cov organic media xws li nyob rau hauv kev tsim cov propylene oxide, tendanium corrosion yog zoo dua li stainless hlau thiab lwm cov txheej txheem txheej txheem.
