Metallographic Microscope Composition & Classification
Metallographic microscope yog ib qho khoom siv siab- thev naus laus zis tsim los ntawm kev sib txuas cov cuab yeej kho qhov muag microscopy, photoelectric hloov dua siab tshiab thev naus laus zis, thiab tshuab computer duab ua tshuab. Nws tuaj yeem yooj yim saib cov duab metallographic ntawm lub computer, tshuaj xyuas thiab qib metallographic spectra, thiab tso tawm thiab luam tawm cov duab. Nws tuaj yeem muab faib ua: upright metallographic microscope (GPM-100, IDL-100), inverted metallographic microscope (MG-MI, GX51, GX41), on-site metallographic microscope (MG-100), thiab lwm yam. Raws li paub zoo, muaj pes tsawg leeg, cov txheej txheem kho cua sov, thiab cov txheej txheem hlau thiab cov txheej txheem kub hloov pauv ncaj qha. li no ua rau kev hloov pauv ntawm cov khoom siv kho tshuab ntawm cov khoom siv kho tshuab. Yog li ntawd, siv lub tshuab ntsuas metallographic los soj ntsuam, tshuaj xyuas, thiab tshuaj xyuas cov qauv sab hauv ntawm cov hlau yog ib qho tseem ceeb hauv kev tsim khoom.
Metallographic microscope yog tsim los ntawm optical system, illumination system, mechanical system, thiab accessories (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, cov kev tshawb fawb kho qhov muag thiab cov lus piav qhia zoo thiab ntau yam ntawm cov ntaub so ntswg yog ua los ntawm kev siv lub tshuab tsom rau hauv qhov pom lub teeb pom kev. Nws tuaj yeem tso saib cov yam ntxwv ntawm cov qauv hlau hauv qhov ntsuas ntawm 500-0.2m. Thaum ntxov li 1841, Russians kawm cov qauv ntawm Damascus steel swords nyob rau hauv ib tug magnifying iav. Los ntawm 1863, tus txiv neej British HC Sorby tau hloov cov txheej txheem ntawm petrology, nrog rau cov qauv npaj, polishing, thiab etching, rau kev tshawb fawb steel, tsim cov txheej txheem metallographic. Tom qab ntawd, nws kuj tau coj ib pawg uas tsis tshua muaj magnification metallographic duab ntawm lwm cov qauv. Kev xyaum tshawb fawb ntawm Sobi 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 thaum ntxov, optical metallographic microscopy tau dhau los ua sophisticated thiab dav siv rau microscopic tsom xam ntawm hlau thiab alloys. Nws tseem yog ib qho tseem ceeb ntawm cov txheej txheem ntawm metallurgy mus rau niaj hnub no.
