Ingabe ithusi le-aluminium lingathathelwa indawo ipuleti lethusi le-tin

Angakwaziithusi le-aluminiumesikhundleni sepuleti lethusi likathayela?
Njengengxube enwebekayo, ipuleti lethusi le-tin lisho ingxube ye-copper-tin equkethe i-Sn≤6.5%, ngokuvamile isaqukethe i-P, Zn nezinye izakhi ze-alloy.Uma futhi iqukethe i-P, ibizwa nge-phosphor-tin bronze, enomkhawulo ophezulu wokunwebeka, i-elastic modulus, ukumelana okuhle Gqoka nokumelana nokugqwala, okulungele ukwakhiwa kwezingxenye ezihlukahlukene zokunwebeka.Okuqukethwe kwe-aluminium yethusi ye-aluminium ngokuvamile akudluli ku-11.5%, futhi ngezinye izikhathi inani elifanele lensimbi, i-nickel, i-manganese nezinye izakhi zengezwa ukuze kuthuthukiswe ukusebenza.Ithusi le-aluminium lingaqiniswa ukwelashwa kokushisa, amandla ayo aphezulu kunepuleti lethusi le-tin, futhi ukumelana kwayo ne-oxidation yokushisa ephezulu nakho kungcono.Isetshenziselwa izikulufu eziqine kakhulu, amantongomane, imikhono yethusi, izindandatho zokuvala, njll., nezingxenye ezingagugi.Isici esigqame kakhulu ukumelana kwayo nokugqoka kahle.Ngethusi le-aluminium eliqukethe insimbi kanye nezakhi ze-manganese, inamandla aphezulu nokumelana nokugqoka.Ngemuva kokucisha nokushisa, ubulukhuni bungakhuphuka, futhi bunokushisa okuphezulu kokugqwala ukumelana nokumelana ne-oxidation.Ukumelana nokugqwala emkhathini, amanzi ahlanzekile namanzi olwandle Kuhle kakhulu, i-machinability iyamukeleka, ingafakwa i-welded futhi ingashisi kalula, futhi ukucubungula ingcindezi kuhle esimweni esishisayo.Kokubili ipuleti lethusi likathayela nethusi le-aluminium yizinto ezimelana nokugqokwa.
Njengoba i-indenter yensimbi ikhubazekile ngesikhathi sokulinganisa, uhlobo lwesihlabathi sohlobo lwensimbi.Usayizi nomthwalo we-indenter kuhlala kungashintshiwe, i-HBS, ikakhulukazi uma impahla yokulinganisa ilukhuni, futhi ubudlelwano phakathi kwe-HBW: HB yinani lobulukhuni be-Brinell: ZCuSn5Pb5Zn5;inani lokuqina kwe-Brinell endinganisweni entsha liyicacisa ngokucacile i-indenter ngesikhathi sokulinganisa : Amandla e-Tensile σb (MPa): I-HBW isho i-carbide indenter enosimende: 590HB.Ngenxa yokuguqulwa kwe-indenter yensimbi ngesikhathi sokulinganisa, izinga elisha linciphisa izintuba kulokhu: ≥90;Ubude δ5 (%): ≥13.Qaphela: I-HWS ibhekisela ku-indenter yensimbi, ngakho-ke nansi umehluko wokuqala, ikakhulukazi uma ukala izinto eziqinile, izinga elisha linciphisa izintuba kulokhu.
