Tasirin maganin cryogenic akan inganta ingancin simintin carbide

Tun daga 1980s, an yi nasarar amfani da maganin cryogenic don ingantawasiminti carbide.Yawancin karatu sun nuna cewa maganin cryogenic yana da wani tasiri mai kyau akan kayan aikin injiniya, sa juriya, yanke aikin, microstructure, da sauran yanayin damuwa na ciminti carbide.Ta hanyar ci gaba da bincike ta masu bincike, an sami jerin dabi'u masu amfani.da kuma ƙarewar mahimmancin kimiyya.

(1) Cryogenic magani iya inganta lankwasawa ƙarfi, sa juriya da yankan yi nasiminti carbide, ta yadda ya kamata mika rayuwar sabis nacemented carbide kayayyakin aiki.Ta hanyar nazarin tasirin sigogin tsarin jiyya na cryogenic akan kaddarorin injiniya na ciminti carbide, an yi imani da cewa tasirin ingantawa na jiyya na cryogenic ba ya canzawa a layi tare da raguwar zazzabin jiyya na cryogenic da haɓaka lokacin riƙewa.Domin takamaiman maki nasiminti carbide, akwai tsarin kulawa na cryogenic mafi kyau, wanda zai iya cimma sakamako mafi kyawun ingantawa a ƙananan farashi.

(2) Babban tasirin maganin cryogenic akan microstructure nasiminti carbidesune: ① canza yanayin halittar hatsi na lokaci mai wuya - WC;② inganta canjin martensitic na lokacin haɗin gwiwa;③ lafiyayyen carbide barbashi (eta lokaci) a cikin Watsewa da hazo akan matrix na kayan.

(3) A martensite canji na bonding lokaci, da hazo na lafiya carbides da kuma karuwa da saura matsawa danniya a kan abu surface bayan cryogenic magani iya muhimmanci inganta ƙarfi da kuma ci juriya na cimented carbide.Sabili da haka, haɓaka abubuwan macroscopic na simintin carbide shine sakamakon haɗin gwiwar haɓaka canjin lokaci da ƙarfafa ƙarfafawa.
