Siv Metallurgical Microscopes hauv Metallurgy thiab Mechanical Industry
① Nws tuaj yeem siv rau kev txheeb xyuas cov ntaub ntawv raw thiab cov txheej txheem.
② Metallographic tshuaj xyuas ntawm cov khoom ua tiav tuaj yeem ua tiav thaum lub sijhawm tsim khoom kom ntseeg tau tias cov khoom siv microstructure ua tau raws li cov txheej txheem ua haujlwm tom ntej.
③ Muaj qee qhov kev sib raug zoo ntawm microstructure thiab cov khoom ntawm cov khoom, raws li cov khoom tsim nyog tuaj yeem xaiv.
④ Nws muab lub hauv paus rau kev ua tau zoo, kev ntseeg siab thiab kev pabcuam lub neej ntawm kev pabcuam hauv qhov chaw.
⑤ Txiav txim thiab txheeb xyuas qhov ua raws ntawm cov txheej txheem khoom.
⑥ Tshawb xyuas cov txheej txheem thiab cov khoom tsis xws luag, txhawm rau muab cov ntaub ntawv pov thawj macroscopic thiab microscopic rau kev ntsuas tsis ua haujlwm.
⑦ Muab cov ntaub ntawv tseem ceeb rau kev kho cov lus qhia tshawb fawb thiab kev tsim khoom.
Kev ua haujlwm ntawm Metallography
① Kev tswj xyuas cov khoom zoo: txhua qhov txuas hauv cov txheej txheem tsim khoom, los ntawm cov khoom siv raw thiab cov txheej txheem tswj mus rau kev soj ntsuam zoo ntawm cov khoom tiav thiab cov khoom tiav.
② Kev tshawb fawb txog kev kho cua sov ntawm cov hlau: Lub hauv paus ntsiab lus ntawm kev kho cua sov ntawm cov hlau yog ua raws theem kev hloov pauv thaum lub sij hawm cua sov thiab cua txias, thiab metallography yog ib qho kev sim loj rau kev tshawb fawb.
③ Txhim kho cov duab nco alloys: Cov duab nco alloys tau tshawb pom los ntawm kev tsom xam metallographic.
④ Kev soj ntsuam tsis ua haujlwm: Cov cuab yeej siv tshuab thiab cov khoom siv tsis raug cuam tshuam los ntawm kev ua haujlwm tsis zoo xws li deformation, tawg, hnav thiab corrosion hauv kev pabcuam. Kev ntsuam xyuas metallographic pab txheeb xyuas qhov ua tsis tiav thiab ntsuas kev tiv thaiv.
⑤ Kev tsom xam qhov xwm txheej: Siv rau kev soj ntsuam thiab pov thawj ntawm kev sib tsoo hluav taws hauv qhov hluav taws kub ua rau kev txheeb xyuas, uas muaj qhov rov ua tau zoo, sib piv thiab pom.
