Maitiro Ekugadzira Sample yeMetallographic yeAluminium neAluminium Alloys uye Midziyo Yekugadzirira Sample yeMetallographic

Zvigadzirwa zvearuminiyamu nearuminiyamu zvinoshandiswa zvakanyanya mukugadzirwa kwemaindasitiri, uye minda yakasiyana yekushandisa ine zvinodiwa zvakasiyana zvakanyanya zve microstructure yezvigadzirwa zvearuminiyamu. Semuenzaniso, mumunda wendege, chiyero cheAMS 2482 chinoisa zvinodiwa zvakajeka zvehukuru hwezviyo uye saizi yezvigadzirwa; muma radiator emotokari, kune zvinodiwa zvakasimba zve porosity yezvikamu zvearuminiyamu alloy. Chinangwa chekuongorora metallographic ndechekuona kana chigadzirwa chakakodzera nekuongorora microstructure yacho.

Kuongororwa kwesimbi kunoshandisa maikorosikopu yemaziso kuona nekunyorahunhu hwechimiro chidiki chearuminiyamu nearuminiyamu, zvakaita sehukuru hwezviyo, chimiro, uye kufanana, kuitira kuona simba uye purasitiki yezvinhu. Inogona zvakare kushandiswa kuongorora saizi, huwandu, mhando, nezvimwe zvinhu zvezvikamu zvechipiri. Munguva yekutarisa, pane zvinodiwa zvekupedzwa kwepamusoro uye kutsetseka kwechinhu chebasa. Kazhinji, kugadzirira sampuro yemetallographic kunodiwa pamberi pebvunzo yekuongorora metallographic kubvisa kukuvara kwepamusoro, kuratidza chimiro chechokwadi chemetallographic chechigadzirwa chebasa, uye kuve nechokwadi chekuti data rekuongorora rinotevera rakarurama.

Matanho ekugadzirira mienzaniso yekuongorora metallographic yezvigadzirwa zvealuminium alloy anowanzo kuve nekucheka metallographic, kuisa, kukuya nekupolisha, uye ngura. Muchina wekucheka metallographic unodiwa kuti utore sampuli, uyo une sisitimu yekutonhodza mvura kudzivirira kushanduka kwechigadzirwa, kupisa pamusoro, uye kukuvara kwechigadzirwa panguva yekucheka.

Pakugadzika, kuisa zvinhu zvinopisa kana zvinotonhora zvinogona kusarudzwa sezvinodiwa; kuisa zvinhu zvinopisa kunonyanya kushandiswa pakugadzira zvinhu zvearuminiyamu. Munguva yekukuya nekupukuta, sezvo zvigadzirwa zvearuminiyamu zvine kuoma kwakaderera, kushandisa sandpaper yakakodzera nejira rekupukuta pamwe chete nemvura yekupukuta kunogona kubatsira kuwana muenzaniso wakanaka kusvika girazi rapera.

Chekupedzisira, pakuita ngura, zvinokurudzirwa kushandisa mushonga wealkaline unoparadza zvishoma kuti usakuvadza microstructure. Mushure mekuora, sampuro inogona kuiswa pasi pemaikorosikopu kuti iongororwe metallographic.
