Abubuwan Superalloys na tushen Nickel

Nickel-tushen ƙera superalloys aji ne na kayan aiki mai girma da aka tsara don keɓaɓɓen ƙarfin injina, juriya, da kwanciyar hankali na tsari a yanayin zafi mai tsayi, yawanci sama da 540°C (1000°F). Kalmar "aikin" yana nuna cewa waɗannan allunan suna siffata su zuwa nau'insu na ƙarshe ta hanyar tsarin thermomechanical kamar ƙirƙira, mirgina, ko extrusion, wanda ke haifar da kyakkyawan tsari, tsarin hatsi na jagora wanda ke ba da ƙarancin ƙarfi da kaddarorin gajiya idan aka kwatanta da takwarorinsu na simintin gyaran kafa. Su ne kashin bayan abubuwan da ke jujjuya yanayin zafi a sararin samaniya da samar da wutar lantarki, inda gazawa ba zabi bane.

Abubuwan Haɗaɗɗen Ƙarfe Masu Haɓaka Zazzabi

Ƙarfe da aka yi da babban zafin jiki na ƙarfe nau'i ne na kayan ƙarfe tare da baƙin ƙarfe (Fe) a matsayin babban kashi, wanda aka ƙera shi don kiyaye ƙarfin injiniya mai kyau da juriya ga lalacewa (kamar oxidation) a yanayin zafi mai tsayi, yawanci a cikin kewayon 540 ° C zuwa 760 ° C (1000 ° F zuwa 1400 ° F). Sunan "aikin da aka yi" yana nuna an tsara su ta hanyar tsarin thermomechanical kamar mirgina mai zafi, ƙirƙira, ko extrusion, waɗanda ke tace ƙananan ƙirar su don samar da ingantaccen haɗin ƙarfi, ductility, da ƙirƙira. Suna aiki azaman bayani mai tsada mai tsada kuma mai dacewa sosai don ɗimbin aikace-aikacen zafin jiki mai yawa, yana daidaita tazarar aiki tsakanin bakin karfe da mafi tsadar nickel ko superalloys na tushen cobalt.

Cobalt-Based Superalloy

Cobalt-Based Superalloy

Superalloys na tushen Cobalt rukuni ne na kayan ƙarfe masu ƙarfi waɗanda aka ƙera don kiyaye ƙarfin injin na musamman, kwanciyar hankali, da juriya na lalata a yanayin zafi mai tsananin zafi, galibi ya zarce waɗanda superalloys na tushen nickel suka fara rauni. Abu ne na ginshiƙi don abubuwan da ke da mahimmanci a cikin mafi yawan wurare masu buƙata, musamman a sararin samaniya, injin injin injin masana'antu, da kayan aikin likita. Babban aikinsu ya samo asali ne daga ƙarfafan matrix na cobalt-chromium da babban ƙarar ƙarfi, barbashi na carbide mai jujjuyawa.
