Ua kom ntseeg tau qhov tseeb ntawm alloy austenitization thiab kev tiv thaiv.
Siv lub siab -purityargon cua rauvNws yog ib qho tseem ceeb los tsim ib qho chaw inert uas tiv thaiv cov hlau los ntawm kev cuam tshuam nrog huab cua nyob ib puag ncig.
Thaum lub sij hawm siab -kub austenitization txheej txheem ntawm 1100 degree, qhov kev tiv thaiv no ncaj qha tiv thaiv oxidation hnyav thiab decarburization, yog li tswj qhov kev ncaj ncees ntawm cov qauv.
Physics ntawm Surface Protection
Tsim ib qho Inert Ib puag ncig
Thaum kub kub zoo li 1100 degree, lub alloy nto ua heev reactive.
Qhia siab -purity argon displaces oxygen thiab lwm yam reactive atmospheric hais nyob rau hauv lub cub tawg chamber.
Qhov no tsim ib qho chaw nruab nrab uas lub cev tiv thaiv cov huab cua los ntawm kev cuam tshuam nrog cov hlau kub.
Tiv thaiv Oxidation hnyav
Yog tsis muaj kev tiv thaiv, kub kub ceev oxidation ntawm tus qauv nto.
Qhov no ua rau kev tsim cov nplai lossis qhov chaw oxides, ua rau cov qauv ua kom puas.
Argon tiv thaiv mitigates cov nyhuv no, xyuas kom cov khoom tseem huv si thiab structurally suab.
Tswj Decarburization
Kev kub siab tuaj yeem ua rau cov pa roj carbon atom diffuse tawm ntawm cov hlau txheej txheej, ib txheej txheem hu ua decarburization.
Qhov kev poob no hloov cov tshuaj lom neeg ntawm qhov chaw, ua rau nws txawv ntawm cov khoom tseem ceeb.
Lub inert argon cua zoo tiv thaiv cov txheej txheem diffusion no, xauv cov pa roj carbon monoxide hauv cov iav siv lead ua.
Kev cuam tshuam rau cov ntaub ntawv thiab kev ntsuas
Ua kom muaj tseeb hauv Kev Tshawb Fawb Carbon
Txhawm rau nkag siab txog cov khoom ntawm martensitic matrix, kev ntsuas meej ntawm cov ntsiab lus hauv zos yog qhov tseem ceeb.
Yog tias decarburization tshwm sim ntawm qhov chaw, qhov ntsuas yuav pom cov ntsiab lus qis carbon tsawg.
Kev tiv thaiv Argon ua kom ntseeg tau tias qhov sib xyaw saum npoo tseem nyob nrog cov khoom siv ntau.
Tshem tawm Kev Ua Phem Tsis Txaus Siab
Scientific validity cia siab rau kev txo qis lwm yam hloov pauv ntau li ntau tau.
Tso cai rau oxidation los yog decarburization qhia "suab nrov" rau hauv cov ntaub ntawv, ua rau kev sim tsis ncaj ncees.
Los ntawm kev tswj cov huab cua, koj tuaj yeem cais qhov sib txawv ntawm kev txaus siab- cov tshuaj tiv thaiv rau cov cua sov- yog li ua kom muaj kev ntseeg siab ntawm koj cov ntaub ntawv.
