Puas yog 45 quenched thiab tempered steel muaj tib yam corrosion tiv taus nyob rau hauv cov xov xwm sib txawv

Lub corrosion tsis kam ntawm 45 quenched thiab tempered steel (45 quenched thiab tempered steel) nyob rau hauv cov xov xwm sib txawv yog qhov sib txawv. Cov hauv qab no yog qhov kev tshawb fawb tshwj xeeb:
Hauv thaj chaw thaj chaw huab cua: 45 Quenched thiab tempered steel yuav hnov ​​mob nrog oxygen, dej vapor, thiab lwm yam nyob rau hauv cov huab cua los tsim cov yeeb yaj kiab oxide rau saum npoo. Yog tias cov av noo nyob rau hauv cov huab cua yog qhov siab lossis muaj qee yam ntawm cov kua qaub (xws li cov roj sulfur, tab sis cov roj corrosion yog qeeb.
Nyob rau hauv ib puag ncig dej ntshiab: feem ntau, 45 quenched thiab tempered steel muaj qee yam corrosion tsis kam nyob rau hauv dej tshiab. Txawm li cas los xij, yog tias cov dej muaj cov pa oxygen ntau dua, cov tshuaj pleev xim rau sab nrauv, nws yuav rhuav tshem cov tshuaj tsw qab rau sab nrauv, thiab ua rau cov hlau mus rau corrode.
Nyob rau hauv ib puag ncig dej hiav txwv Chloride Ions muaj cov txheej txheem loj heev thiab tuaj yeem ua kom muaj cov txheej txheem uas ua kom zoo dua qub, ua kom muaj kev nrawm nrawm xws li pitting thiab compevice corrosion.
Hauv cov acidic nruab nrab: 45 quenched thiab tempered steel muaj kev tsis zoo corrosion tsis kam nyob hauv cov acidic nruab nrab. Piv txwv li, nyob rau hauv cov acid muaj zog xws li hydrochloric acid thiab sulfuric acid, cov hlau yuav hnov ​​mob siv tshuaj thiab yaj nrawm, ua rau muaj kev nrawm nrawm, ua rau muaj kev nrawm nrawm. Txawm nyob hauv qee qhov chaw nyob ib puag ncig tsis muaj zog, kev sib cuag ntev yuav maj mam txo cov kev ua tau zoo ntawm cov hlau.
Hauv qhov nruab nrab alkaline: 45 Quenched thiab tempered steel muaj zoo corrosion zoo nyob rau hauv alkaline nruab nrab. Feem ntau cov kev daws teeb meem tsis muaj zog, ib zaj yeeb yaj kiab tiv thaiv yuav tsim nyob rau saum npoo ntawm cov hlau mus rau corrosion ntxiv corrosion. Txawm li cas los xij, yog hais tias cov concentration ntawm alkali kev daws teeb meem yog qhov siab thiab qhov kub yog siab, nws kuj tseem tuaj yeem ua rau cov hlau.
Yog tias koj xav paub cov corrosion tsis kam ntawm 45 quenched thiab tempered steel tsis kam nyob rau ntau tshaj xov xwm, koj tuaj yeem sab laj rau peb cov neeg ua haujlwm hauv siab 24 teev hauv ib hnub!
