Nickle chrome alloy VS Inconel 718
Nickle chrome alloy VS Inconel 718
Inconel 718 yog qhov tshwj xeeb, siab -kev ua haujlwm nag lossis daus-nickel hardening-chromium superalloy, thaum "nickel-}chromium alloy" yog ib lo lus dav dav rau ntau yam nickel-chromium alloys. Inconel 718 nthuav tawm lub zog tensile zoo, qaug zog, thiab creep rupture lub zog ntawm qhov kub txog li 700℃(1290℃F), ua rau nws yog ib qho khoom siv zoo tshaj plaws rau aerospace / turbines. Txawm li cas los xij, piv rau tus qauv nickel{11}}chromium alloys, nws kim dua thiab nyuaj rau kev ua haujlwm.
Dab tsi yog qhov tsis zoo ntawm Inconel 718?
However, the disadvantages of Inconel 718, such as its high density, high melting point, and difficulty in machining, limit its application in the manufacture of complex parts. Yog li ntawd, xaiv laser melting (SLM) tshuab muab ib txoj hauv kev zoo los tsim cov khoom nyuaj los ntawm Inconel 718 alloys.
1. Kev piav qhia ntawm Inconel 718 thiab Nickel-Chromium Alloys
"Nickel-chromium alloys" yog cov khoom siv dav dav, thiab Inconel 718 yog ib tus neeg tshwj xeeb, siab -kawg. Kev nkag siab txog kev sib raug zoo nrog rau qhov no yog thawj kauj ruam hauv kev xaiv txoj cai.
Nickel-chromium alloys (txhais tau dav dav):Hais txog tsev neeg ntawm cov alloys nrog npib tsib xee (Ni) thiab chromium (Cr) ua cov ntsiab lus tseem ceeb. Lawv muab kev tiv thaiv corrosion thiab oxidation tsis kam los ntawm kev tiv thaiv oxide zaj duab xis tsim los ntawm chromium, thiab toughness thiab tsis kam los txo cov xov xwm los ntawm nickel matrix. Qhov no yog ib qho txuas ntxiv ntawm kev lag luam mus rau siab - kev ua tau zoo, nrog rau cov neeg sawv cev xws li:
Inconel 600 (Ni-Cr-Fe):Ib qho kev daws teeb meem yooj yim ntxiv dag zog rau alloy, tiv taus siab -kub oxidation.
Incoloy 800/800H (Ni-Fe-Cr):Lub tshav kub- tiv taus alloy nrog cov nqi zoo heev- ua tau zoo.
Inconel 625 (Ni-Cr-Mo-Nb):Ib qho kev daws teeb meem ntxiv dag zog rau alloy nrog zoo heev corrosion kuj.
Inconel 718 (Ni-Cr-Fe-Nb):Hom nag lossis daus hardening, sab saum toj -tier lub zog thiab siab - kub ua haujlwm.
Inconel 718 belongs rau nickel-chromium alloy tsev neeg, tab sis nws qhov kev ua tau zoo tau zoo dua los ntawm kev sib ntxiv ntawm niobium (Nb), molybdenum (Mo), aluminium (Al), thiab titanium (Ti) thiab daim ntawv thov ntawm nag lossis daus hardening kho cua sov. Nws yog tsim los rau qhov chaw huab cua uas xav tau ultra- lub zog siab, zoo heev - qhov kub thiab txias, thiab zoo corrosion kuj.
Ib qho piv txwv tseem ceeb:Yog tias npib tsib xee-chromium alloys zoo li "tsheb," ces Inconel 600/625 yog cov "tsev neeg sedans" thiab "SUVs," thaum Inconel 718 yog ib qho saum toj kawg nkaus - ntawm -- kab "Formula 1 race car," ua rau kev ua tau zoo heev.
2. Kev sib piv ntawm Inconel 718 nrog cov dav dav dav - lub hom phiaj nickel-chromium alloys (siv Inconel 625 ua piv txwv)
