Imvula Iqinisa Ukusakaza Kwensimbi Engagqwali

I-OEMimikhiqizo eyenziwe ngokwezifiso yokutshala imalieyenziwe kwezulu iqinisa insimbi engagqwali kusukaI-China foundry.

Imvula eyenza insimbi engagqwali ibe lukhuni ibhekisela ohlotsheni lwensimbi engagqwali enezela izinhlobo ezahlukene nenani lezinto eziqinisayo, futhi izinhlobo ezahlukene nenani lama-carbides, ama-nitride, ama-carbonitrides nezinhlanganisela ze-intermetallic ziyaziswa ngenqubo yokuqina kwemvula. Imvula eyenza insimbi engagqwali ibe lukhuni ayigcini nje ngokuba namandla aphezulu, kodwa futhi inokuqina okuhle nokumelana nokugqwala. Ngokusakazwa kwensimbi eqinisa imvula equkethe ithusi, ubulukhuni bokubunjwa kwensimbi buyanda ngenxa yokuna kwezigaba ezinothile ngethusi eliqinile esimweni sokupholisa phakathi nenqubo yokupholisa. Ukuze uthambise isakhiwo futhi uthuthukise ukusebenza kokucubungula, ukukhishwa kwensimbi okunjalo kudinga ukwelashwa kokushisa kwesisombululo. Izinga lokushisa eliqinile lesisombululo semvula eqinisa insimbi equkethe ithusi ngokuvamile liyi-900 ℃ ~ 950 ℃. Ngemuva kokupholisa, kungatholwa isakhiwo sesigaba esisodwa esine-supersaturated mass mass ingxenye engu-1.0% ~ 1.5%.

I-precipitation iqinisa insimbi engagqwali isetshenziswa kakhuluizimboni eziphambili. Isibonelo, imvula evamile eyenza insimbi engagqwali ibe lukhuni engu-17-4PH ingasetshenziswa ukwenza izakhiwo ezingaphansi kuka-370°C ezidinga ukumelana nokugqwala, ukumelana nokuguga, namandla aphezulu.
