Isingeniso Sokuvikelwa Komkhiqizo Wensimbi
Insimbi engazweli ukushisa ibhekisa kwinsimbi enokumelana nama-oxidation aphezulu aphezulu kanye namandla aphezulu okushisa . Insimbi ephakeme yokushisa i-air yokushisa, i-oxidive chempeling} ukukhiqizwa okuphezulu kwensimbi off . Ukuze uthuthukise ukumelana nokushisa okuphezulu kwe-oxidation yensimbi, izinto ezengeziwe zengezwa ngensimbi ukuze zishintshe ukwakheka kwe-oxium, noma i-aluminum ye-oxis I-Al2o3, ngaphezulu kwensimbi ukuvikela insimbi kusuka ku-oxidation . Lapho inani le-chromium, kepha i-aluminium yokuvikelwa kwensimbi ilungile, kepha i-aluminium yokuvikelwa kwensimbi iba kubi kakhulu, ngakho-ke i-aluminic yensimbi iba kubi kakhulu Into ye-Alloying, ne-Silicon ne-Aluminium njengezinto ezisizayo, ngamafuphi, ukumelana nokushisa okuphezulu kwe-oxidation yensimbi kuhlobene kuphela nokwakheka kwamakhemikhali .
Amandla okushisa aphezulu abhekisa emandleni ensimbi ukumelana nemithwalo emishini emazingeni okushisa aphezulu isikhathi eside . Insimbi ngaphansi kwengxenye yokushisa, okungukuthi, amandla epulasitiki akhuphuka kancane ngokunwebeka kwesikhathi, okubangelwa yinsimbi ephezulu I-Intragrazekar Slip kanye ne-Grame Slip Slip . Indlela yokufaka i-alloying ivame ukusetshenziselwa ukuthuthukisa amandla okushisa aphezulu wensimbi njll ., angaqinisa i-matrix yensimbi, futhi athuthukise izinga lokushisa kabusha kabusha, futhi akhiphe i-CR23c, njenge-CR23C, ayihlanganisi, ayigcini, futhi akhule, alondoloze ubulukhuni bawo . I-nickel yengezwa ikakhulukazi ukuthola i-aucen ., ama-athomu e-austomite ahlelwe ngaso eduze, amandla aphezulu okushisa anamandla okushisa angcono kakhulu ukwakheka, kepha kuhlobene nenhlangano .
