Gadziridzo yeAluminium Foam ine Uniform Kugovera kweDiki Pore Size neNovel Composite Foaming Agent.

Simbi dzakaputika, kunyanyaaluminium foam, ari kuwedzera kushandiswa zvakanyanya mumunda wezvinhu. Iyo melt foaming process yakashandiswa zvakanyanya mukugadzirwa kwemaindasitiri nekuda kwepamusoro kugadzirira kwayo uye kugadzikana kwechigadzirwa zvivakwa. Kunyangwe hukama chaihwo pakati pezvivakwa uye chimiro chepore hachisati chanyatsonzwisiswa, furo dzakagovaniswa dzakafanana dzine saizi diki dzepore uye hurema hushoma dzinogara dzichidiwa zvakanyanya.

Parizvino, saizi yepore uye chimiro chealuminium foamszvinonetsa kudzora panguva yekunyunguduka kwefuro, uye zvinonetsa kugadzira mafuro ealuminium ane madiki pore saizi, kunyanya nekuda kwekuora kwekutanga uye kusapararira kwakanaka kweanofuridza agent (kazhinji TiH2). Kubva pane izvi, boka raProfessor Yanxiang Li paYunivhesiti yeTsinghua rakadzidza maitiro ekutanga kupararira kweTiH2 mukunyunguduka kweAlMg35 yepakati alloy mushure mekurapa oxidation, iyo inogona kupedzisa kupararira pasina kuora, uye yakagadzira AlMg35-TiH2 itsva. composite furo agent. Mhedzisiro yekukurudzira nguva uye kuvhuvhuta mumiriri dosage pamhando yeinoenderana aluminium furo yakaongororwawo. Mhedzisiro yekutsvagisa yakaburitswa mujenari "Journal of Materials Processing Technology" ine zita rekuti "Development of AlMg35-TiH2 composite foaming agent uye kugadzirwa kwediki pore size aluminium foams". Chinyorwa cheZvigadzirwa Processing Technology.Aluminium foamsyakagadzirirwa neiyi composite inopupuma agent inoratidzirwa nechimiro chakanaka, diki pore saizi, yunifomu pore kugovera uye spherical pore chimiro. Kuvandudzwa kweichi chiitiko ndechekuti zvimedu zveTiH2 zvinoparadzirwa munzvimbo yakaderera yekunyungudika alloy inonyungudika nekurebesa nguva uye haisi nyore kuora.

Iyo inofuridza yakabudirira mukugadzira yakanakisa uye inodhinda masero maumbirwo emapores madiki mumafuro ealuminium ane yakaderedzwa avhareji pore saizi ye 0.6 mm, iyo yainyanya kukonzerwa nekunonoka kuparara nguva yeTiH2 nekuda kwe pre-oxidation kurapwa uye AlMg35 yakaiswa mairi. , izvo zvakaita kuti nguva yekukurudzira iwedzere kushivirira. Iwo pre-oxidized TiH2 zvimedu zvakaparadzirwa mumvura AlMg35 alloy, zvichiita kuti zvive nyore kuparadzira zvimedu zveTiH2 mualuminium inonyunguduka ine zvishoma particle aggregation. Uye zvakare, iyo nzira inoderedza huwandu hweTiH2 yakawedzerwa padanho rekupupa, iro risingadhure uye rakanyanya kukodzerakugadzirwa kwemaindasitiri.
