Iron tushen gami/Nickel tushen gami/Nickel tushen gami/lalata resistant superalloy superalloy farantin karfe

Superalloys na tushen nickel rukuni ne na hazo da aka ƙarfafa gami waɗanda ke aiki da kyau a cikin yanayin zafi mai ƙarfi. Kyawawan kaddarorin yanayin zafin jiki na tushen nickel superalloys sun haifar da aiwatar da wannan nau'in gami a cikin aikace-aikacen sararin samaniya da yawa.

Ƙarfe superalloy wani nau'i ne na superalloy. An kwatanta shi ta hanyar ƙara wasu abubuwa akan tushen ƙarfe don haɗawa. Daidai da ma'aunin ƙarfe na tushen ƙarfe sune superalloys na tushen nickel da na tushen cobalt.

Superalloys na tushen Cobalt kayan aiki ne da ake amfani da su a cikin matsanancin zafin jiki da matsanancin yanayi tare da kyakkyawan ƙarfin zafin jiki, juriya na lalata da juriya. Superalloys na tushen Cobalt galibi sun ƙunshi abubuwa kamar cobalt, chromium, tungsten, nickel da aluminum.

Lalata resistant super alloys samar da wani karuwa a inji ƙarfi, juriya ga thermal nakasawa, da juriya ga lalata idan aka kwatanta da na gargajiya gami, da bukatar ƙasa da kiyayewa da kuma mafi kyau jure matsananci yanayi. Ana ci gaba da ƙoƙarin yin sabbin gyare-gyaren gyare-gyaren gyare-gyaren gyare-gyaren gyare-gyare irin su aluminum-based super alloys, da kuma samar da sababbin hanyoyin masana'antu irin su radiolysis wanda ke amfani da nano-barbashi kira ga polycrystalline samuwar.

Babban juriya na zafin jiki da juriyar lalata na superalloy ya dogara ne akan tsarin sinadaransa da tsarinsa. Ɗaukar Inconel718 nickel-based deformed superalloy a matsayin misali, da gami ya ƙunshi wani γ matrix lokaci, wani δ lokaci, a carbide, da kuma ƙarfafa γ' da γ "lokaci. The sinadaran abubuwa da matrix tsarin na Inconel718 alloy nuna da karfi inji Properties, da yawan amfanin ƙasa ƙarfi da tensile ƙarfi ne 5 karfe fiye da 5 sau fiye da karfe 4, fiye da karfe 4. Tsarin lattice da babban adadin abubuwan ƙarfafawa suna ba da gudummawa ga kyawawan kaddarorin injin sa.

Saboda hadadden yanayi da matsananciyar yanayin aiki na superalloys, amincin injin da aka kera yana taka muhimmiyar rawa a cikin aikinsa. Duk da haka, superalloy ne na hali da wuya aiwatar da abu, ta micro-ƙarfafa abu taurin ne high, mataki na aiki hardening ne mai tsanani, kuma yana da high karfi danniya da kuma low thermal watsin, yankan karfi da yankan zafin jiki a cikin yankan yankin, sau da yawa bayyana a cikin aiki na low surface quality, kayan aiki lalacewa ne mai tsanani da kuma sauran matsaloli.

Superalloys su ne alluran juriya na zafi na nickel, iron-nickel, da cobalt waɗanda za a iya amfani da su a yanayin zafi mai yawa, sau da yawa> 70% na yanayin narkewar su. Ana iya amfani da su a yanayin zafi sama da 1050 ° C tare da balaguron balaguro zuwa 1200 ° C. Wannan yanayin juriyar yanayin zafi ya sa ya zama ɗan takarar da ya dace don Tungsten Carbide a cikin aikace-aikacen Pick Up.

Mafi yawan nau'in Superalloy da ake amfani da shi shine kayan da ke da nickel wanda ya ƙunshi babban taro na chromium, iron, titanium, cobalt da sauran abubuwa masu haɗawa. Kamar yadda yake tare da sauran ƙungiyoyin kayan ƙarfe, ana iya daidaita kaddarorin superalloys tare da jiyya daban-daban na zafi da/ko kashewa da kashewa.
