Ob nqe lus nug koj yuav tsum them sai sai rau thaum yuav ib lub ntsuas phoo metallographic
1. Nyob rau saum toj no, peb qhia txog cov kev cai uas nws lub tshuab tsom iav tsom iav yuav tsum sib ntsib. Ntawm no, peb xav qhia rau koj tias cov tseem ceeb tivthaiv ntawm Muallographic tsom kwm yog lub kaw lus kho qhov muag, uas tau muab faib ua plaub ntu ntawm cov tsom iav tsom iav. Metallographic tsom xam cov ntsiab cai kom tau txais cov duab hlau (piv txwv li kev coj ua cov qauv hlau thiab kev ntsuas ntau ntawm cov qauv hlau. Qhov zoo tshaj ntawm kev kuaj yog thawj qhov taw qhia rau ntsuas qhov ntsuas qhov zoo ntawm kev ntsuas me me ntawm cov tsom iav. Txhawm rau txais cov duab ntshiab, plaub qhov xwm txheej yuav tsum tau ua tiav: siab sib txawv, lub ci ci siab, thiab cov kev daws teeb meem siab. Thawj peb qho kev mob tau yooj yim dhau los ntawm cov neeg siv thaum xaiv, thiab cov neeg siv yuav tsum tsis dig muag rau kev tsis pom peb lub sijhawm thaum tsis saib xyuas peb peb yam. Tsuas yog nyob rau hauv txoj kev no tuaj yeem ua rau lawv ua tiav tus nqi rau nyiaj thiab ua kom zoo tshaj plaws siv cov peev txheej.
2. Thaum siv lub ntsuas phoo metallographic, cov nyhuv ruaj khov ntawm lub tsom iav yuav tsum tau txiav txim siab. Nyob rau hauv kev siv sijhawm ntev, nws yog tus kws tshawb fawb, xws li hauv kev tshawb fawb txog kev tshawb fawb thaum siv cov tshuaj tiv thaiv metallographic. Lub neej ua hauj lwm li qub ntawm metallographic microscopes tau ncav cuag 30 xyoo. Thaum lub sijhawm ntawd muaj kev pabcuam ntev ntev, qhov zoo ntawm kev ntaus nrig ntawm Moog metallographic yog tshwj xeeb yog qhov tseem ceeb. Txawm hais tias nws yog cov ntaub ntawv ntau lawm lossis kev paub meej kev paub tseeb, ntsuas phoo metallographic microscopes yuav tsum muaj cov teebmeem no.
Cov no yog ob qhov teeb meem peb yuav tsum them sai sai rau thaum yuav cov metallographic tsom iav. Nws tseem yog ib qho tseem ceeb kom nco ntsoov tias seb puas yuav xaiv siv cov tsom iav me me lossis yuav cov me me ntxiv, peb yuav tsum ua raws li cov kev yuav khoom.
