Ngaba i-aluminiyam yobhedu inokutshintshwa ngepleyiti yobhedu yetin

Ngabaubhedu aluminiyamkufakwe ipleyiti yenkcenkce yobhedu endaweni yayo?
Njenge-alloy elastic, ipleyiti yobhedu ye-tin ibhekisa kwi-alloy ye-copper-tin equkethe i-Sn≤6.5%, ngokuqhelekileyo iqulethe i-P, i-Zn kunye nezinye izinto ze-alloy.Ukuba ikwaqulethe i-P, ibizwa ngokuba yi-phosphor-tin yobhedu, enomlinganiselo ophezulu weelastiki, imodyuli elastiki, ukuxhathisa okulungileyo;Umxholo we-aluminium we-aluminium ubhedu ngokuqhelekileyo awudluli kwi-11.5%, kwaye ngamanye amaxesha isixa esifanelekileyo sentsimbi, i-nickel, i-manganese kunye nezinye izinto zongezwa ukuphucula ngakumbi ukusebenza.Ubhedu lwe-aluminiyam lunokomelezwa ngonyango lobushushu, amandla ayo aphezulu kunepleyiti yobhedu yetin, kwaye ukuxhathisa kwayo kwi-oxidation yobushushu obuphezulu nako kungcono.Isetyenziselwa izikrufu eziphakamileyo, iinati, imikhono yobhedu, imisesane yokutywina, njl.Eyona nto ibalaseleyo kukuxhathisa kwayo kakuhle.Kwibronzi ye-aluminium equlethe isinyithi kunye nezinto ze-manganese, inamandla aphezulu kunye nokumelana nokunxiba.Emva kokucima kunye nokufudumala, ubunzima bunokwandiswa, kwaye bunokumelana nokushisa okuphezulu kwe-corrosion kunye nokumelana ne-oxidation.Ukumelana ne-Corrosion kwi-atmosphere, amanzi ahlambulukileyo kunye namanzi olwandle Kuhle kakhulu, ukucwangciswa kwe-machina kwamkelekile, kunokudityaniswa kwaye kungabi lula, kwaye ukucutshungulwa koxinzelelo kulungile kwindawo eshushu.Zombini ipleyiti yenkcenkce yobhedu kunye ne-aluminiyam yobhedu zizinto ezixhathisayo.
Ekubeni i-indenter yensimbi ikhubazekile ngexesha lokulinganisa, uhlobo lwesanti yensimbi.Ubungakanani kunye nomthwalo we-indenter uhlala ungatshintshi, i-HBS, ngakumbi xa izinto zokulinganisa zinzima, kunye nobudlelwane phakathi kwe-HBW: I-HB yixabiso lobunzima beBrinell: ZCuSn5Pb5Zn5;ixabiso lobulukhuni beBrinell kumgangatho omtsha lichaza ngokucacileyo i-indenter ngexesha lomlinganiselo : Amandla okuqina σb (MPa): I-HBW ibhekisa kwi-carbide indenter enesamente: 590HB.Ngenxa yokuguqulwa kwe-indenter yensimbi ngexesha lokulinganisa, umgangatho omtsha unciphisa izithuba kulo mba: ≥90;Ubude δ5 (%): ≥13.Qaphela: I-HWS ibhekisela kwi-indenter yensimbi, ngoko ke nantsi ukuhlukana kokuqala, ngakumbi xa ulinganisa izinto ezinzima, umgangatho omtsha unciphisa izithuba kulo mba.
