Tsarin Shirya Samfurin Metallographic na Aluminum da Aluminum da Kayan Aikin Shirya Samfurin Metallographic

Ana amfani da kayayyakin aluminum da aluminum sosai a masana'antu, kuma fannoni daban-daban na aikace-aikace suna da buƙatu daban-daban ga ƙananan tsarin kayayyakin aluminum. Misali, a fannin sararin samaniya, ma'aunin AMS 2482 ya kafa buƙatu bayyanannu don girman hatsi da girman kayan aiki; a cikin radiators na motoci, akwai ƙa'idodi masu tsauri don porosity na sassan ƙarfe na aluminum. Saboda haka, manufar nazarin ƙarfe shine a tantance ko samfurin ya cancanci ta hanyar nazarin ƙananan tsarinsa.

Binciken ƙarfe yana amfani da na'urar hangen nesa ta gani (optical microscope) don lura da rikodinhalaye na ƙananan tsarin ƙarfe na ƙarfe na aluminum da aluminum, kamar girman hatsi, yanayin halitta, da daidaito, don tantance ƙarfi da ƙarfin kayan. Hakanan ana iya amfani da shi don nazarin girma, yawa, nau'i, da sauran halaye na matakai na biyu. A lokacin aikin lura, akwai buƙatu don kammala saman da kuma lanƙwasa na kayan aikin. Yawanci, ana buƙatar shirya samfurin ƙarfe kafin gwajin nazarin ƙarfe don kawar da lalacewar saman, bayyana ainihin tsarin ƙarfe na kayan aikin, da kuma tabbatar da cewa bayanan bincike na gaba sun fi daidai.

Matakan shirya samfurin don nazarin ƙarfe na samfuran ƙarfe na aluminum gabaɗaya sun haɗa da yanke ƙarfe, hawa, niƙa da gogewa, da kuma tsatsa. Ana buƙatar injin yanke ƙarfe don tsarin ɗaukar samfur, wanda aka sanye shi da tsarin sanyaya ruwa don hana lalacewar samfur, ƙonewa a saman, da lalacewar tsari yayin yankewa.

Don tsarin hawa, ana iya zaɓar hawa mai zafi ko sanyi kamar yadda ake buƙata; galibi ana amfani da hawa mai zafi don samfuran aluminum na gargajiya. A lokacin niƙa da gogewa, tunda samfuran aluminum suna da ƙarancin tauri, amfani da takarda mai dacewa da zane mai gogewa tare da ruwan gogewa na iya taimakawa wajen samun kyakkyawan saman samfurin har sai an sami kammala madubi.

A ƙarshe, don tsarin tsatsa, ana ba da shawarar amfani da maganin alkaline mai laushi don guje wa lalata ƙananan tsarin. Bayan tsatsa, ana iya sanya samfurin a ƙarƙashin na'urar hangen nesa don nazarin ƙarfe.
