(Inconel 718 Powder kanye nokuwohloka kwayo)

I-Inconel 718 powder idlala indima ebalulekile ezinqubweni zokukhiqiza okungeziwe. Izakhiwo zayo zihlanganisa amandla amahle emishini emazingeni okushisa aphakeme, ukumelana nokugqwala, namandla okukhathala. Ngenxa yokushisela kwayo okuphezulu, isetshenziswa kakhulu kwi-aerospace ne-gas turbine application. Kulolu cwaningo, izifunda ezine zempushana zaphenywa ukuze kuphenywe umthelela wokucekelwa phansi kwezakhiwo zempushana. Izici zezimpushana ezine zaqhathaniswa futhi zabonakala ngokuya ngokugeleza, i-morphology, kanye nezakhiwo ze-physicochemical.

Ukuhlaziywa kwe-laser diffraction kwenziwa ezinhlayiyeni eziyimpushana. Ukusatshalaliswa kosayizi wezinhlayiyana kunqunyelwe izinhlayiyana ngayinye. Lezi zibe sezisetshenziselwa ukubala indawo elinganayo eqanjiwe yezinhlayiyana ngayinye. Zonke izinhlayiya zatholakala zine-morphology efanayo, ezinokwehluka okuncane kuphela.

Ukugeleza kwezifunda ezine kukalwe kusetshenziswa i-HORIBA LA-960 laser particle size analyzer. Kwabe sekuqhathaniswa ukusatshalaliswa kosayizi wezinhlayiyana ze-virgin kanye nempushana egaywe kabusha. Lokhu kwenzelwa ukuhlonza amazinga okuwohloka ngemva kokusetshenziswa kaningi.

Kuthathwe uchungechunge lwezithombe ezincane zempushana ukuze kubonakale ukumila nokusabalalisa usayizi wempushana. Kusetshenziswe isibonakhulu se-EVO MA25 esinomtshina we-EDS ukuze kutholwe lezi zithombe.

Kusetshenziswa isofthiwe ye-ImageJ 1.53a, izithombe ezincane zezinhlayiyana ngayinye zahlaziywa ukuze kuhlolwe ukwakheka kwayo, ukuthungwa, kanye nesici sangaphakathi. Izindawo ze-oxidation nazo zabonwa. Iningi lezinhlayiya ze-spatter azizange zibonise amabala e-oxide, ngaphandle kwenani elincane lezinhlayiya ezinongqimba olujiyile oluyi-oxidized ngaphezulu.
