Intshayelelo
Ii-Super alloys zinamandla okusebenza kumaqondo obushushu aphezulu kakhulu kunye noxinzelelo loomatshini, kwaye nalapho kufuneka uzinzo oluphezulu lomphezulu. Zinokumelana okuhle kokuqhekeka kunye nokuxinana, kwaye zinokuveliswa ngeendlela ezahlukeneyo. Zinokuqiniswa ngokuqina kwesisombululo esiqinileyo, ukuqina komsebenzi, kunye nokuqina kwemvula.
Ii-Super alloys ziqulathe inani lezinto ezidityanisiweyo ukuze kufezekiswe iziphumo ezifunwayo. Zihlulwahlulwa zibe ngamaqela amathathu afana nee-cobalt-based, nickel-based, kunye nee-iron-based alloys.
I-Incoloy(r) alloy 825 yi-alloy ye-nickel-iron-chromium eyongezwa kunye nezinye izinto zokudibanisa ukuze kuphuculwe ipropati yayo yokumelana nokugqwala ngamakhemikhali. Olu luhlu lwedatha lulandelayo luza kubonelela ngeenkcukacha ezithe vetshe malunga ne-Incoloy(r) alloy 825.
