Chii chinonzi foaming agent yealuminium?

Pane nzira huru dzakasiyana dzealuminium furo, kusanganisira nzira yekunyungudusa furo, upfu metallurgy foaming nzira uye yechipiri foaming nzira.
Melt foaming nzira inzira yekugadzira furo chimiro mune liquid aluminium. Iyo chaiyo maitiro ndeyekuwedzera viscosity inowedzera mumiriri, senge silicon carbide kana alumina, kune yakanyungudutswa aruminiyamu fluid kuitira kuti iwedzere viscosity yealuminum fluid uye kutadzisa mabhubhu kusimuka nekubatanidza nekukurumidza. Zvadaro, mumiriri anopupa, senge titanium hydride kana hydrogen zirconium hydride, inowedzerwa kune liquid aluminium, uye aya anopupa anoora patembiricha yakakwira kuti abudise magasi anoita kuti liquid aluminium iwedzere uye furo. Nekudzora huwandu hwekufuridza mumiriri wakawedzerwa, tembiricha yekuparara uye viscosity yealuminium fluid, saizi uye kugoverwa kwemabhuru egasi kunogona kugadziriswa, izvo zvinozoita kutialuminium foamnechimiro chaidiwa. Mushure mekutonhora uye kusimba, yakavharwa-sero kana yakavhurika-sero aluminium foam zvinhu inogadzirwa.
Powder metallurgy foaming nzira ndeyekugadzirira aluminium furo pahwaro hwehupfu hwealuminium hwakasimba. Chekutanga, iyo aruminiyamu poda inosanganiswa neinofuridza uye inotsikirirwa pasi peimwe dzvinyiriro kuita dense prefabricated block. Zvadaro, zvidhinha zvakagadzirirwa zvinoiswa muchoto chekupisa uye zvinopisa kuti zvivhare pedyo nekunyunguduka kwealuminium, panguva iyo iyo inoputika inotanga kuora, uye gasi rinogadzirwa rinoita kuti zvivharo zvakagadzirirwa zviwedzere kuumba porous chimiro. Nekugadzirisa tembiricha yekupupa, nguva uye density yezvakagadzirwa zvidhinha, iyo porosity uye pore chimiro chealuminium foaminogona kudzorwa. Iyo poda metallurgy foaming nzira yakakodzera kugadzirira zvigadzirwa zvealuminium foam zvine maumbirwo akaomarara uye yakakwira porosity zvinodiwa.
Yechipiri yekupupa nzira inosanganisa zvakanakira nzira yekunyungudutsa furo uye poda metallurgy foaming nzira. Iyo inotanga kuwedzera viscosity inowedzera mumiririri uye inopupuma mumiriri wealuminium inonyunguduka, inosanganiswa zvakanaka uye inokandira muforoma yekukasira kutonhora uye kusimba kuti iwane inopupuma precursor. Kana iyo precursor ichidziya kune imwe tembiricha, iyo inopupuma inotanga kuora uye kupupa, uye pakupedzisira inoburitsa furo realuminium. Iyi nzira inogona kudzora zvirinani chimiro chepore uye zvimiro zvealuminium furo kuburikidza nematanho maviri-anopupa maitiro, uye akakodzera kugadzirira yepamusoro-kuita.aluminium foamzvinhu.
Kune nzira dzakasiyana dzealuminium kupupa, uye imwe neimwe nzira ine yakasarudzika maitiro maitiro uye chiyero chekushandisa. Mukushanda kwekushanda, nzira yakakodzera inogona kusarudzwa maererano nezvinodiwa uye mamiriro ekugadzirira kwealuminium foam.
