Usetyenziso lwe-injini ye-aero kunye ne-injini yegesi esekwe emhlabeni

Izicelo ze-injini yomoya kunye ne-injini yerhasi esekwe emhlabeni kwiimveliso ze-Powder Metallurgy zifuna iipropati ezilunge kakhulu kwaye iindlela zenkqubo ezisekwe kwi-PM kweli candelo ngokubanzi zibandakanya i-Hot Isostatic Pressing (HIP).

Kwiidiski ze-nickel-based superalloy turbine discs, ukusetyenzwa kwi-powders kuye kwaba yimfuneko ukuvumela ukunyuka okulandelayo ekusebenzeni kwemveliso, ngolawulo oluphuculweyo lwe-microstructural kunye nokukwazi ukuhlanganisa xa kuthelekiswa nemathiriyeli yendlela ye-ingot.Inkqubo ye-Powder Metallurgy ngokubanzi ibandakanya ukubunjwa kwe-isothermal yebillet ye-HIP, nangona iindawo "njenge-HIP" zinokusetyenziswa apho amandla ahambayo ikuphela komgaqo woyilo.

Iimveliso ze-HIP ze-titanium Powder ze-Net-shape ye-Net-shape ziye zaphuhliselwa usetyenziso lwe-injini yomoya apho ukusetyenzwa kwesiqhelo (okubandakanya ukwenziwa komatshini) kuyinkcitho eninzi yemathiriyeli kwaye indlela ye-Powder Metallurgy inokubonelela ngeenzuzo zeendleko.Ukongezwa kweempawu kwiindawo ezibunjiweyo okanye ezityhidiweyo kusetyenziswa iindlela zokwenza ezongezelelo ezisekwe ngumgubo zikwasetyenziswa ngezizathu ezifanayo.

Icandelo le-Airframe

I-Metallurgy yomgubo yinkqubo ekhethiweyo yokwenziwa kweendawo ezahlukeneyo ezakhiweyo ngenxa yeendleko zayo.

Kukwakho umdla okhulayo wokusetyenziswa kwePowder Metallurgy kwicandelo le-airframe, nokuba kukugcinwa kweendleko kwizicelo esele zisebenzisa i-titanium yendlela eyenziweyo okanye ukunciphisa ubunzima obunokubakho ekutshintsheni iinxalenye zentsimbi.
