Kev Tiv Thaiv Kev Ntsuas Rau Intercrystalline Corrosion

Kev tiv thaiv kev tiv thaiv rau intercrystalline corrosion

Intercrystalline corrosion yog ib daim ntawv loj ntawm cov khoom tsis ua haujlwm, feem ntau ua rau cov cuab yeej ua haujlwm poob qis thiab muaj kev nyab xeeb. Txhawm rau tiv thaiv qhov tshwm sim ntawm intercrystalline corrosion, yuav tsum muaj kev tiv thaiv zoo.

Ua ntej, xaiv cov ntaub ntawv intercrystal corrosion resistant yog qhov tseem ceeb. Thaum xaiv cov ntaub ntawv, lawv cov corrosion kuj nyob rau hauv ib qho chaw tshwj xeeb yuav tsum tau txiav txim siab tag nrho. Piv txwv li, rau cov cuab yeej siv hauv kev tshaj tawm muaj zog corrosion, cov ntaub ntawv alloy uas muaj zog corrosion kuj, xws li stainless hlau, npib tsib xee-raws li alloy, yuav tsum tau xaiv.

Qhov thib ob, kev tswj cov txheej txheem ntawm cov khoom siv kuj yog ib qho kev ntsuas tseem ceeb los tiv thaiv intercrystalline corrosion. Nyob rau hauv cov txheej txheem ntawm kev kho cua sov thiab vuam ntawm cov ntaub ntawv, cov txheej txheem tsis yuav tsum tau nruj me ntsis tswj kom tsis txhob muaj kev ntxhov siab nyob rau hauv ntau seem thiab grain ciam dilution tshwm sim. Tsis tas li ntawd, kev kho qhov chaw tsim nyog ntawm cov khoom siv, xws li txau cov tshuaj tiv thaiv corrosion, electroplating, thiab lwm yam, tuaj yeem txhim kho nws cov corrosion kuj zoo.

Tsis tas li ntawd, kev tswj hwm ntawm ib puag ncig yam tseem ceeb kuj yog kev tiv thaiv ntawm intercrystalline corrosion. Hauv kev siv cov cuab yeej siv, qhov kev txhim kho corrosion ntawm cov khoom tsis zoo hauv nruab nrab yuav tsum zam. Piv txwv li, rau cov cuab yeej siv hauv cov khoom siv tshuaj, cov khoom siv sab hauv yuav tsum tau ntxuav tsis tu ncua kom tsis txhob muaj cov khoom corrosive. Nyob rau tib lub sijhawm, rau cov cuab yeej siv hauv qhov kub thiab txias, cov av noo thiab lwm qhov chaw hnyav, yuav tsum tau ua raws li kev tiv thaiv kev tiv thaiv, xws li ntxiv dag zog rau kev sib khi ntawm cov khoom siv, siv cov khoom noj khoom haus, thiab lwm yam.

Thaum kawg, tsis tu ncua kev soj ntsuam thiab kev ntsuam xyuas ntawm corrosion kuj ntawm cov ntaub ntawv kuj yog ib qho tseem ceeb txhais tau tias los tiv thaiv intercrystalline corrosion. Intercrystalline corrosion tuaj yeem zam tau los ntawm kev kuaj xyuas cov khoom siv corrosion tsis tu ncua thiab nrhiav thiab kho cov teeb meem corrosion hauv lub sijhawm. Nyob rau tib lub sijhawm, qhov kev ntsuam xyuas ntawm kev tiv thaiv corrosion ntawm cov ntaub ntawv tuaj yeem muab lub hauv paus kev tshawb fawb rau kev xaiv cov khoom siv thiab ua cov txheej txheem ntawm cov khoom siv.

Txhawm rau ua kom tiav, kev tiv thaiv ntawm intercrystalline corrosion yuav tsum tau pib los ntawm kev xaiv cov khoom siv, kev tswj cov txheej txheem, kev tswj hwm ib puag ncig thiab kev tshawb nrhiav tsis tu ncua, thiab ua kom tiav cov kev ntsuas kom ntseeg tau tias cov cuab yeej muaj peev xwm ua haujlwm ruaj khov thiab ntseeg tau hauv ib puag ncig hnyav.
