I-Precious Metal Re yokushisa okuphezulu kwe-alloy
Incazelo
I-Rhenium (Re) iyinsimbi ephikisayo eyivelakancane eyivelakancane futhi eyigugu enezici ezihlukile eziyenza ithandeke kakhulu ekusetshenzisweni okuhlukahlukene.Iyisiliva-emhlophe, insimbi esindayo enezinga eliphezulu lokuncibilika kanye nokuminyana okuphezulu, okuyenza ibe into efanelekile ukusetshenziswa ezindaweni ezishisayo nezinokucindezeleka okukhulu.
Enye yezinhlelo eziyinhloko ze-rhenium ekukhiqizeni ama-alloys asezingeni eliphezulu ukuze asetshenziswe ezinjinini zejethi.Eqinisweni, cishe amaphesenti angama-70 e-rhenium yomhlaba asetshenziswa ngale ndlela.I-Rhenium yengezwa kulawa ma-alloys ukuze kuthuthukiswe ukusebenza kwawo okunezinga lokushisa eliphezulu, okuhlanganisa amandla awo, ukuqina, nokumelana nokuguga nokugqwala.
Okunye ukusetshenziswa okubalulekile kwe-rhenium ekukhiqizeni ama-catalyst e-platinum-rhenium.Lawa ma-catalyst asetshenziswa embonini yamakhemikhali ukuze akhuthaze ukuguqulwa kwama-hydrocarbon nezinye izinhlanganisela zibe imikhiqizo ewusizo, njengophethiloli, amapulasitiki, namanye amakhemikhali.
Ngaphezu kwalezi zinhlelo zokusebenza, i-rhenium iye yasetshenziswa nakweminye imikhakha, njengasembonini ye-aerospace yamarokhethi nozzle kanye nasembonini ye-electronics ukuxhumana nogesi nezinye izakhi.Ngenxa yokungatholakali kwayo kanye nezindleko eziphakeme, i-rhenium ibhekwa njengensimbi eyigugu futhi ihlonishwa ngenxa yezakhiwo zayo eziyingqayizivele kanye nohlu olubanzi lwezinhlelo zokusebenza.
