Douluo, kuv qhov system tsis ntseeg lawm
Metallographic microscope yog siv los txheeb xyuas thiab tshuaj xyuas cov qauv sab hauv thiab lub koom haum ntawm cov hlau. Nws yog ib qho cuab yeej tseem ceeb rau kev tshawb fawb metallographic thiab cov cuab yeej tseem ceeb rau cov tuam tsev lag luam los ntsuas cov khoom zoo. Lub cuab yeej yog nruab nrog lub koob yees duab, uas tuaj yeem ntes cov duab kos duab metallographic, ntsuas thiab txheeb xyuas cov duab kos, thiab hloov kho, tso tawm, khaws cia, thiab tswj cov duab.
Metallographic microscope yog cov khoom siv thev naus laus zis uas tsim los ntawm kev sib txuas cov tshuab kho qhov muag, tshuab photoelectric hloov dua siab tshiab, thiab tshuab computer duab ua tshuab. Nws tuaj yeem yooj yim saib cov duab metallographic ntawm lub computer, tshuaj xyuas thiab qib metallographic maps, thiab tso tawm thiab luam tawm cov duab. Raws li paub zoo, muaj pes tsawg leeg ntawm cov alloys, cov txheej txheem kev kho cua sov, thiab cov txheej txheem txias thiab kub ua haujlwm ncaj qha cuam tshuam rau lub koom haum sab hauv thiab cov qauv kev hloov ntawm cov ntaub ntawv hlau, yog li ua rau kev hloov pauv ntawm cov khoom siv ntawm cov khoom. Yog li ntawd, siv lub tshuab ntsuas metallographic los soj ntsuam, tshuaj xyuas, thiab tshuaj xyuas cov txheej txheem sab hauv ntawm cov hlau yog ib qho tseem ceeb hauv kev tsim khoom.
Metallographic microscopes feem ntau muaj cov tshuab kho qhov muag, teeb pom kev zoo, tshuab tshuab, thiab cov khoom siv ntxiv (nrog rau kev yees duab lossis lwm yam khoom siv xws li microhardness).
Raws li cov yam ntxwv ntawm lub teeb pom kev sib txawv ntawm cov ntaub so ntswg sib txawv ntawm cov qauv hlau, kev tshawb fawb kho qhov muag tau ua los ntawm kev siv lub tshuab tsom iav hauv qhov pom lub teeb pom kev kom zoo thiab ntau yam piav qhia txog cov ntaub so ntswg. Nws tuaj yeem tso saib cov yam ntxwv ntawm cov hlau microstructure hauv qhov ntsuas ntawm 500-0.2m. Thaum ntxov li 1841, cov Russians (п.п.Ансов) Kuv kawm cov qauv ntawm Damascus steel ntaj nyob rau hauv ib tug magnifying iav. Los ntawm 1863, cov British (HC Sorby) tau hloov cov qauv ntawm petrography, nrog rau cov qauv kev npaj, polishing, thiab etching cov tswv yim, rau txoj kev kawm ntawm steel, tsim metallographic cov tswv yim, thiab tom qab ntawd tsim ib pawg ntawm cov duab uas tsis tshua muaj magnification metallographic ntawm lwm cov ntaub so ntswg. Cov kev xyaum tshawb fawb ntawm Soby thiab nws cov neeg kawm, Germans (A. Martens) thiab Fabkis (F. Osmond), tau tsim lub hauv paus rau niaj hnub optical metallographic microscopy. Los ntawm lub xyoo pua 20th, optical metallographic microscopy tau maj mam txhim kho thiab tau nthuav dav rau kev tsom xam ntawm cov hlau thiab cov hlau. Nws tseem yog ib qho tseem ceeb hauv kev siv tshuab metallurgy mus txog niaj hnub no.
Metallographic microscope yog ib hom kab mob uas siv lub teeb pom kev zoo li lub teeb pom kev zoo. Discrete thiab kab rov tav, [optical microscope a vertical microscope b horizontal microscope]. Lawv tag nrho suav nrog optical amplification, teeb pom kev zoo, thiab tshuab tshuab.
Lub amplification system yog tus yuam sij rau kev cuam tshuam rau kev siv thiab kev siv tshuab microscopes zoo. Feem ntau yog tsim los ntawm lub hom phiaj lo ntsiab muag thiab eyepieces.
