Ese umuringa wa aluminiyumu ushobora gusimburwa na tin bronze

Birashobokaumuringa wa aluminiumgusimburwa na tin bronze?
Nkumuti wa elastike, isahani yumuringa yerekana umuringa-amabati urimo Sn≤ 6.5%, mubisanzwe urimo P, Zn nibindi bintu bivangwa.Niba kandi irimo P, yitwa fosifore-tin bronze, ifite imipaka ihanitse ya elastike, modulus ya elastique, irwanya neza Kwambara no kurwanya ruswa, bikwiranye no gukora ibice bitandukanye bya elastique.Ibirimo bya aluminiyumu ya bronze ya aluminiyumu muri rusange ntibirenza 11.5%, kandi rimwe na rimwe urugero rwinshi rwa fer, nikel, manganese nibindi bintu byongeweho kugirango turusheho kunoza imikorere.Umuringa wa aluminiyumu urashobora gushimangirwa no kuvura ubushyuhe, imbaraga zawo zikaba nyinshi kuruta iz'isahani y'umuringa, kandi kurwanya imbaraga za okiside yo hejuru na byo ni byiza.Ikoreshwa mumashanyarazi akomeye, ibinyomoro, amaboko y'umuringa, impeta zifunga, nibindi, hamwe nibice bidashobora kwambara.Ikintu kigaragara cyane ni ukurwanya kwambara neza.Kuri bronze ya aluminium irimo ibyuma na manganese, ifite imbaraga nyinshi kandi irwanya kwambara.Nyuma yo kuzimya no gutwarwa, ubukana burashobora kwiyongera, kandi bufite ubushyuhe bwiza bwo kurwanya ruswa no kurwanya okiside.Kurwanya ruswa mu kirere, amazi meza n’amazi yo mu nyanja Nibyiza cyane, imashini irashobora kwemerwa, irashobora gusudwa kandi ntishobora gusya byoroshye, kandi gutunganya igitutu nibyiza mubihe bishyushye.Amabati yombi yumuringa hamwe na aluminium bronze ni ibikoresho birwanya kwambara.
Kubera ko ibyuma byerekana ibyuma byahinduwe mugihe cyo gupima, ubwoko bwicyuma cyumucanga.Ingano n'umutwaro wa indenter ntigihinduka, HBS, cyane cyane iyo ibikoresho byo gupima bigoye, kandi isano iri hagati ya HBW: HB nigiciro gikomeye cya Brinell: ZCuSn5Pb5Zn5;agaciro gakomeye ka Brinell murwego rushya rugaragaza neza indenter mugihe cyo gupimwa: Imbaraga zingana σb (MPa): HBW bivuga indimu ya sima ya sima: 590HB.Bitewe no guhindura ibyuma byerekana ibyuma mugihe cyo gupima, ibipimo bishya bigabanya icyuho muriki kibazo: ≥90;kurambura δ5 (%): ≥13.Icyitonderwa: HWS bivuga ibyuma byerekana ibyuma, dore rero itandukaniro ryambere, cyane cyane iyo upimye ibikoresho bikomeye, urwego rushya rugabanya icyuho muriki kibazo.
