Maganin Zafi na Carburizing don Gears: Inganta Ƙarfi, Dorewa & Aiki

A cikin tsarin watsa wutar lantarki na zamani, ana sa ran gears za su yi aiki a ƙarƙashin yanayi mai tsauri, juyawa mai ci gaba, nauyi mai yawa, saurin canzawa, da kuma tsawon lokacin aiki.

Don shawo kan waɗannan ƙalubalen, maganin zafi ya zama muhimmin mataki a cikin kera kaya, kuma daga cikin dukkan hanyoyin,carburizingya fito fili a matsayin ɗaya daga cikin hanyoyin da suka fi tasiri wajen taurare saman.

Carburizing (wanda kuma ake kira hardening case) wata dabara ce ta ƙarfe wadda ke shigar da carbon cikin saman gears na ƙarfe a zafin jiki mai yawa. Bayan an kashe shi, saman yana canzawa zuwa akwati mai tauri na martensitic yayin da zuciyar ke riƙe da tauri da juriyar girgiza. Wannan haɗin yana da tauri a waje, mai tauri a ciki. Shi ya sa ake amfani da gears ɗin da aka yi da carburized sosai a cikin watsawa na motoci, akwatunan gear na masana'antu, manyan injina, kayan haƙar ma'adinai, tuƙi na sararin samaniya, da kuma na'urorin robot.

Menene Carburizing?

Carburizing wani nau'in maganin zafi ne da aka yi ta hanyar yaɗawa wanda ake yi a yanayin zafi tsakanin 880°C – 950°C. A lokacin aikin, ana dumama giya a cikin yanayi mai cike da carbon. Kwayoyin carbon suna yaɗuwa zuwa saman ƙarfe, suna ƙara yawan sinadarin carbon. Bayan jiƙa shi na tsawon lokacin da ake buƙata, ana kashe giya da sauri don samar da akwati mai tauri na martensitic.

Zurfin shigar carbon ana kiransa zurfin akwati, kuma ana iya sarrafa shi ta hanyar yanayin zafi daban-daban, lokacin riƙewa, da ƙarfin carbon. Gabaɗaya, zurfin akwatin da aka nufa yana daga 0.8 mm zuwa 2.5 mm, ya danganta da aikace-aikacen, girman gear, da ƙarfin kaya da ake buƙata.
