Corrosion resistance yog hais txog lub peev xwm ntawm cov khoom los tiv thaiv cov tshuaj corrosion nyob rau hauv tej yam kev mob ib puag ncig. Nws yog qhov tseem ceeb hauv kev lag luam xws li kev tsim kho tshuaj, kev tsim kho, kev xa khoom, aerospace, thiab lwm yam. Corrosion tsis tsuas yog ua rau txo qis zog thiab kev ua haujlwm ntawm cov kav hlau steel, tab sis kuj ua rau muaj kev nyab xeeb thiab kev poob nyiaj txiag.
Qhov tsim ntawm corrosion kuj yog ze ze rau cov tshuaj muaj pes tsawg leeg, lub cev muaj zog thiab qhov chaw ntawm cov khoom. Cov ntaub ntawv sib txawv tuaj yeem pom qhov sib txawv tseem ceeb hauv kev tiv thaiv corrosion thaum raug rau tib qhov chaw corrosive. Piv txwv li, stainless hlau thiab titanium alloys muaj tshwj xeeb alloy Cheebtsam thiab nto passivation txheej, qhia tau zoo heev corrosion kuj. Txawm li cas los xij, cov hlau zoo tib yam yog rusting nyob rau hauv cov av noo thiab acidic ib puag ncig, thiab tus nqi corrosion yog sai dua.
Sib nrug los ntawm cov yam ntxwv ntawm cov hlau nws tus kheej, ib puag ncig yam tseem ceeb muaj feem cuam tshuam rau corrosion kuj. Kub, av noo, pH tus nqi, oxygen concentration, thiab muaj cov corrosive media tag nrho cuam tshuam tus nqi ntawm corrosion. Nyob rau hauv siab - kub thiab siab - av noo ib puag ncig, tus nqi corrosion ntawm hlau feem ntau accelerates.
Kev kho saum npoo ntawm cov kav hlau tuaj yeem txhim kho lawv cov kev tiv thaiv corrosion los ntawm kev siv lub cev lossis tshuaj. Cov thev naus laus zis xws li txheej txheej, plating thiab anodizing tuaj yeem tsim cov yeeb yaj kiab tiv thaiv ntawm cov hlau nto, tiv thaiv kev cuam tshuam ntawm corrosive media, ua kom lub neej ntev ntawm cov kav dej steel thiab txhim kho kev ntseeg tau ntawm cov khoom.
Kev tiv thaiv corrosion tsis tsuas yog cuam tshuam rau kev ua haujlwm thiab kev siv cov hlau, tab sis kuj cuam tshuam rau kev nyab xeeb thiab kev lag luam ntawm cov khoom. Los ntawm kev xaiv cov khoom tsim nyog, xav txog ib puag ncig thiab siv cov thev naus laus zis kho saum npoo, qhov corrosion kuj ntawm cov hlau tuaj yeem txhim kho. Nrog rau kev txhim kho thev naus laus zis, yuav muaj kev tsim kho tshiab thiab kev ua kom zoo dua qub hauv corrosion-cov ntaub ntawv thiab cov thev naus laus zis yav tom ntej, muab cov kev daws teeb meem txhim khu kev qha rau ntau yam lag luam.
