Chikonzero chatinosarudza aruminiyamu yekushongedza imhaka yekuti chimiro chayo chakanyanya kugadzikana, uye ine corrosion resistance mukushandiswa kwenguva refu.Nekudaro, mamwe maaruminiyamu profiles anozove nekuora pamusoro, izvo zvinonyanya kukonzerwa nekuumbwa kwezvinhu zvisirizvo panguva yekugadzira.
1. Mukuita kwekukanda, chikamu che magnesium nesilicon hachina kukodzera, sekuvapo kweimwe silicon yakasara, iyo ine silicon shoma mukusununguka, ichaita ternary compounds mualuminium alloy panguva imwe chete. .Izvi zvisinganyunguriki zvetsvina zvikamu kana mahara ehutsvina nhanho akaumbwa mune alloy anowanzo kuunganidza pamuganhu wezviyo, uye anonetesa simba nekuoma kwemuganhu wezviyo panguva imwe chete, inova iyo isina kusimba link yekudzivirira ngura, uye ngura inotanga kubva ipapo.
2. Muchigadziro chekunyunguduka, kunyange zvazvo chikamu che magnesium nesilicon chiri mukati mehutano, asi dzimwe nguva nekuda kwekusaenzana uye kusina kukwana kusanganiswa, zvichiita kuti kugoverwa kusina kufanana kwesilicon mukunyunguduka, kune nzvimbo dzakapfuma uye nzvimbo dzine urombo.Iyo diki yemahara silicon mualuminium matrix haingoderedze kushora kwekupokana kwealloy, asiwo coarse saizi yezviyo zvealloy.
3. Kudzora kweakasiyana siyana tekinoroji parameters panguva extrusion, akadai bhawa preheating tembiricha yakawandisa, simbi extrusion kuyerera mwero, mhepo kutonhora simba panguva extrusion, kuchembera tembiricha uye kubata nguva uye kumwe kutadza kudzora zviri nyore kubudisa silicon segregation uye. dissociation, kuitira kuti magnesium nesilicon zvisaite zvachose Mg2Si, imwe yemahara silicon iripo.
Muchidimbu, kana pamusoro peiyo aruminiyamu profiles iri nyore kuita ngura mukushandiswa, imhaka yekuti mhando yemhando yealuminium profil yakadzikira mukugadzirwa, saka isu tinofanirwa kutsvaga mugadziri ane hunyanzvi pakusarudza iyo aluminium mbiri, saka iyo aluminium mbiri iwe. sarudza ichave yakachengeteka zvakanyanya.
