Corrosion mechanism thiab qaug zog kuaj
Kev Taw Qhia
Corrosion yog ib qho txheej txheem tsis tu ncua, txuas ntxiv mus, thiab feem ntau yog txheej txheem rov qab tsis tau.Kev lag luam, corrosion yuav cuam tshuam rau kev pab cuam lub neej ntawm cov cuab yeej siv, ua rau cov khoom puas tsuaj, thiab kuj coj lwm yam kev puas tsuaj;Hais txog kev nyab xeeb, kev xeb loj tuaj yeem ua rau raug mob.GRGTEST muab cov txheej txheem Corrosion thiab cov kev pabcuam kev qaug zog kom tsis txhob poob.
