Izicelo ze-aero-injini kanye ne-land-based gas turbine

Izicelo zenjini ye-aero-based kanye ne-land-based turbine yemikhiqizo ye-Powder Metallurgy zidinga izakhiwo ezinhle kakhulu futhi imizila yenqubo esekelwe ku-PM kulo mkhakha ngokuvamile ihlanganisa i-Hot Isostatic Pressing (HIP).

Kumadiski eturbine e-nickel asuselwe ku-superalloy, ukucutshungulwa kusuka kuzimpushana kuye kwaba kudingekile ukuze kuvunyelwe ukunyuka okulandelayo ekusebenzeni komkhiqizo, ngokulawulwa okuthuthukisiwe kwe-microstructural kanye nekhono lokuhlanganisa uma kuqhathaniswa nokokusebenza komzila we-ingot.Inqubo ye-Powder Metallurgy ngokuvamile ihilela ukwakhiwa kwe-isothermal ye-billet ye-HIP, nakuba izingxenye ze-"as-HIP" zingasetshenziswa lapho amandla okukhasa kuyiwona wodwa umbandela wokuklama.

Imikhiqizo ye-HIP titanium Powder Metallurgy enomumo weNet yenzelwe ukusetshenziswa kwe-turbine lapho ukucubungula okuvamile (okubandakanya imishini) kumosha kakhulu impahla futhi umzila we-Powder Metallurgy unganikeza izinzuzo zezindleko.Ukwengezwa kwezici ezingxenyeni ezifojiwe noma eziphonswe kusetshenziswa izindlela zokukhiqiza izithasiselo ezisuselwa kumpushana nakho kusetshenziswa ngezizathu ezifanayo.

Umkhakha we-Airframe

I-powder metallurgy iyinqubo yokukhiqiza ekhethwayo yezingxenye ezihlukahlukene ezihlelekile ngenxa yezindleko zayo eziphumelelayo.

Kuphinde kube nentshisekelo ekhulayo ekusetshenzisweni kwe-Powder Metallurgy emkhakheni we-airframe, kungaba okonga izindleko ezinhlelweni esezivele zisebenzisa i-titanium yomzila owenziwe noma ngokunciphisa isisindo ekushintsheni izingxenye zensimbi.
