Daim Ntawv Qhia Tag Nrho rau Inconel 718 (GH4169): Cov Khoom, Cov Khoom Sib Tw, Cov Ntawv Thov
Inconel 718 (tseem hu ua GH4169, UNS N07718, los yog W.Nr 2.4668) yog npib tsib xee-raws li nag lossis daus- hardening superalloy renowned rau nws lub zog tshwj xeeb, corrosion kuj, thiab thermal stability tshaj qhov kub ntawm qhov kub ntawm qis rau 700℃F (130 degree). Nws lub peev xwm los tswj cov khoom siv hluav taws xob siab hauv qhov chaw huab cua ua rau nws ua lub hnub qub ua yeeb yam hauv aerospace, roj thiab roj, thiab kev lag luam hluav taws xob. Txawm li cas los xij, cov khoom no tseem ua rau nws nyuaj rau kev siv tshuab, xav tau cov tswv yim ua tiav thiab tshwj xeeb.
GH4169 sib npaug li cas?
ib 718
GH4169 (sib npaug rau American hom Inconel 718) yog nag lossis daus-nickel hardening-raws li superalloy dav siv hauv kev lag luam aerospace vim nws cov khoom siv kho tshuab zoo heev (Lu li al., 2014).

3. Machining Sib tw thiab kev daws teeb meem rau Alloy GH4169
ib 718yog cais raws li "nyuaj-rau- tshuab" alloy vim muaj ntau yam: siab txiav quab yuam, siab thermal siv hauv cheeb tsam shear, thiab thermal conductivity tsawg, uas ua rau cov cua sov siab ntawm qhov txiav.
Machining Challenges:
Rapid flank hnav:Ua los ntawm qhov kub thiab txias thiab abrasive qhov ntawm cov khoom.
Built edge (BUE):Cov khoom zoo li ua raws li cov cuab yeej, txo qhov zoo ntawm qhov chaw.
Ua hauj lwm hardening:Cov txheej txheem tshiab txiav cov ntaub ntawv hardens, ua rau tom qab txiav nyuaj dua.
Cov kev coj ua zoo tshaj plaws thiab kev daws teeb meem:
Kev xaiv cuab yeej:Siv cov cuab yeej ntse, zoo rake kaum carbide (coated carbide nrog 8-12% cobalt yog tus qauv). Cov cuab yeej ceramic yog tsim rau kev ua tiav high-speed.
Txiav ceev thiab pub tus nqi:Siv cov kev txiav qis qis (15–30 m / min rau cov cuab yeej carbide; siab dua rau cov cuab yeej ceramic) thiab siab, cov khoom noj tas li kom ntseeg tau tias qhov tob ntawm kev txiav yog qis dua qhov ua haujlwm - txheej tawv.
Rigidity:Siv cov cuab yeej siv siab -rigidity tshuab thiab fixtures kom txo qis kev vibration thiab tiv thaiv cov cuab yeej puas tsuaj.
Coolant:High-siab, siab-flow- tus nqi coolant yog ib qho tseem ceeb rau cov cua kub dissipation.
Qhov tob ntawm kev txiav:Siv qhov tob loj txaus ntawm kev txiav kom tsis txhob nyob hauv qhov chaw ua haujlwm - txheej tawv tawv thiab rov txiav dua.
