Daawaha birta ku salaysan/Nikkel-ku-salaysan daawaha/Nikkel-ku-salaysan daxalka u adkaysta superalloy superalloy

Superalloys-ku-saleysan nikkel waa fasalka xoojiyey da'ay alloys ee si fiican uga shaqeeya jawi heerkul sare ah. Sifooyinka heerkul sarreeya ee heerkulbeegga sare ee nikkel-ku-salaysan waxay keeneen hirgelinta fasalkan alloys ee codsiyada hawada sare ee badan.

Superalloy-ku-saleysan birta waa nooc ka mid ah superalloy. Waxaa lagu gartaa in lagu daro walxo kale oo ku salaysan birta si loo isku daro. U dhiganta superalloys-ku-saleysan birta waa nikkel-ku-saleysan superalloys iyo kobalt-ku-saleysan.

Superalloys-ku-saleysan Cobalt waa maaddooyin lagu isticmaalo heerkul sare iyo deegaan aad u daran oo leh awood heerkul aad u sarreeya, iska caabin daxalka iyo xirashada caabbinta. Superalloys-ku-saleysan waxay inta badan ka kooban yihiin walxo ay ka mid yihiin kobalt, chromium, tungsten, nikkel iyo aluminium.

Daxalka u adkeysiga super Alloys waxay bixiyaan kororka xoogga farsamada, caabbinta qallafsanaanta kulaylka, iyo iska caabinta daxalka marka la barbar dhigo alloys dhaqameed, oo u baahan dayactir yar iyo u adkeysiga jawiga adag. Waxaa socda dadaallo lagu doonayo in lagu sameeyo daxalka cusub ee u adkeysanaya sida aluminiumka super Alloys-ku-saleysan, iyo in la abuuro habab cusub oo wax-soo-saar ah sida shucaac (radiolysis) oo ka faa'ideysanaya isku-dhafka nano-particle ee sameynta polycrystalline.

Iska caabinta heerkulka sare iyo iska caabbinta daxalka ee superalloy waxay inta badan ku xiran tahay isku dhafka kiimikada iyo qaab dhismeedka. Qaadashada Inconel718 nickel-based superalloy deformed tusaale ahaan, daawadu waxay ka kooban tahay γ matrix wajiga, wejiga δ, carbide, iyo γ 'iyo γ "waji la xoojiyay. Walxaha kiimikada iyo qaab-dhismeedka matrix ee Inconel718 alloy waxay muujinayaan sifooyinkeeda farsamo ee xooggan, xoogga wax-soo-saarka iyo xoogga xajinta 4 ayaa sidoo kale 5 ka fiican birta birta ah 4. Qaab dhismeedka shabaqlaha ah iyo tiro badan oo ah arrimo xoojinaya ayaa gacan ka geysta sifooyinkeeda farsamo ee aadka u fiican.

Iyada oo ay ugu wacan tahay jawiga shaqada ee adag iyo qallafsan ee superalloys, daacadnimada dusha mashiinada ayaa door muhiim ah ka ciyaara waxqabadkeeda. Si kastaba ha ahaatee, superalloy waa wax caadi ah oo ay adag tahay in la farsameeyo walxaha, sheyga xoojinta micro-engegnaanta waa mid sare, heerka adkeynta shaqadu waa mid halis ah, waxayna leedahay cadaadis sare oo xiirid ah iyo kulaylka kuleylka hooseeya, xoogga goynta iyo heerkulka goynta ee aagga goynta, inta badan waxay u muuqataa farsamaynta tayada hoose ee dusha sare, dhaawaca qalabku waa mid aad u daran iyo dhibaatooyin kale. Xaaladaha goynta guud, lakabka sare ee superalloy wuxuu soo saari doonaa dhibaatooyin aad u weyn sida lakabka adag, walbahaarka haraaga ah, lakabka cad, lakabka madow iyo lakabka qallafsanaanta hadhuudhka.

Superalloys waa alwaaxyo iska caabbinta kulaylka ee nikkel, iron-nickel, iyo cobalt kuwaas oo loo isticmaali karo heerkul sare, inta badan>70% heerkulkooda dhalaalka. Waxaa lagu isticmaali karaa heerkul ka sarreeya 1050 ° C iyada oo loo dalxiis tago ilaa 1200 ° C. Sifadan u adkaysiga heerkulka ayaa ka dhigaysa musharrax ku habboon beddelka Tungsten Carbide ee codsiyada Pick Up.

Nooca ugu badan ee la isticmaalo ee Superalloy waa walxo ku salaysan nikkel oo ka kooban xoojiye sare oo ah chromium, iron, titanium, cobalt iyo walxo kale oo alloying ah. Sida kooxaha kale ee walxaha birta ah, sifooyinka superalloys waxaa lagu hagaajin karaa daawaynta kulaylka kala duwan iyo/ama nuglaynta iyo deminta. Marka la barbardhigo kooxaha kale ee walxaha, Superalloys waxay leeyihiin heerkulka adeegga ugu sarreeya iyo qiimayaasha ugu sarreeya. Awoodda Superalloys waxay ka dhigaysa beddelka ugu fiican ee Carbide ee codsiyada xoogga curaarta sare (> 1kg).
