Titanium Alloy phaj kuj yooj yim nyob rau hauv ib puag ncig ntawm kev txo cov acidgacic acid thiab nws yog qhov nyuaj los tswj cov yeeb yaj kiab passcide. Txhawm rau kom ua kom zoo txo corrosion, ntxiv corrosion inhibitors tau dhau los ua kev ntsuas zoo. Muaj ntau hom corrosion inhibitors, suav nrog cov hlau hlau, oxidizing inorganic compounds, thiab complex accicic corrosion inhibitors. Txawm li cas los xij, cov hlau hlau muaj nuj nqis yog tsis tshua muaj siv los ua corrosion inhibitors rau txo cov kua roj inorganic vim lawv tus nqi siab. Cov hlau hnyav, xws li tooj liab thiab hlau ions, muaj qhov tseem ceeb corrosion inhibition inhibition inhibition tom qab mus txog ib qho kev xav tseem ceeb. Oxidizing inorganic compounds xws li nitric acid, chlorine, poov tshuaj chlorchaate thiab hydrogen peroxivate thiab hydrogen peroxide kuj muaj qee cov nyhuv corrosion inhibition. Oxidizing organic tebchaw, xws li nitro lossis nitroso sib txuas thiab nitrogen sib xyaw, kuj tseem siv tau rau corrosion inhibition. Cov organic corrosion inhibitor sib txawv, nws tuaj yeem ua rau muaj kev tiv thaiv corrosion, nws tuaj yeem ua rau muaj kev xav, tsuas yog qhov loj ntawm lub luag haujlwm sib txawv.
Los ntawm kev kho deg, tuaj yeem txhim kho lub corrosion tsis kam ntawm titanium alloy phaj. Feem ntau siv cov txheej txheem kho deg muaj xws li Cathodic oxidation, thermal oxidation, nitriving thiab coated txheej thev naus laus zis. Qee cov ntaub ntawv qhia tias txheej txheej txheej pom tseeb tshaj plaws hauv kev txhim kho lub corrosion tsis kam ntawm torrosion tsis kam ntawm ti -0. 15PD.
Qhov anodic oxidation kev kho mob ntawm titanium alloy phaj feem ntau nqa tawm hauv 5% {% (NH4) daws nrog ib qho kev sib txheeb ntxiv nrog 25v dc voltage. Qhov kev kho no tau tshem tawm cov hlau steel stain rau saum npoo, ntev ntev ntawm lub sijhawm passive ntawm titanium alloy phaj, thiab tiv thaiv kom haum hydrogen nqus los ntawm hlau staining. Yog li ntawd, txawv teb chaws cov cai yuav tsum muaj tag nrho cov khoom siv titanium kom raug anodized. Txhawm rau txhim kho cov nyhuv ntawm anodizing, qee zaum sodium platinate yog siv hloov chaw ntawm ammonium sulfate ua ib qho kev ua kom muaj kev tiv thaiv corrosion zoo dua.
Thermal oxidation kev kho mob nyob rau hauv huab cua, titanium alloy phaj tuaj yeem tsim cov yeeb yaj kiab thiab ntau dua crystall thiab ntau dua crystall oxide zaj duab xis, thiab nws cov yeeb yaj kiab cryodic yog qhov zoo dua li ntawm anodic oxide zaj duab xis. Thermal oxidation kev kho mob feem ntau nqa tawm ntawm qhov kub ntawm 600-700 degree rau {1}} feeb. Kev ntsuas kub dhau los yog ntev heev yuav cuam tshuam cov nyhuv kho.
Nyob rau hauv lub txheej ntawm titanium alloy daim hlau, palladium-muaj cov txheej txheem txheej txheem yog siv tau tshwj xeeb. Palladium-muaj cov txheej txheem palladium yog feem ntau yog palladium oxide txheej lossis palladium txuam txheej txheej txheej. Ib txoj kev npaj ua rau lub Palladium oxide txheej PDCLICE Titanium phaj, thiab tom qab ntawd los ua kom sov nws ntawm {} degree rau {7}} feeb. Tus txheej txheem no tuaj yeem rov ua dua ob peb zaug kom ua tiav cov txheej txheej ntawm 1 g / m² lossis ntau dua. Palladium-alloyed txheej, ntawm qhov tod tes, yog thawj zaug tsim los ntawm cov khoom siv hluav taws xob, thiab tom qab ntawd lub tshuab nqus dej los ntawm cov khoom tso tawm saum npoo av lossis one txhim kho kom txhim kho adhesion thiab corrosion tsis kam. Cov kev kho mob no tau zoo heev rau Palladium oxide txheej.
