Ukulungiswa Kwegwebu Le-Aluminium Ngokusatshalaliswa Okufanayo Kosayizi Abancane Bembotshana nge-Novel Composite Foaming Agent

Izinsimbi ezifakwe amagwebu, ikakhulukazii-aluminium foam, ziya ngokuya zisetshenziswa kabanzi emkhakheni wezinto zokwakha. Inqubo yokuncibilika kwegwebu isetshenziswe kabanzi ekukhiqizeni izimboni ngenxa yokusebenza kahle kwayo okuphezulu kanye nezakhiwo zomkhiqizo ozinzile. Nakuba ukuhlobana okuqondile phakathi kwezakhiwo nokwakheka kwezimbotshana akukaqondwa ngokugcwele, amagwebu asatshalaliswa ngokulinganayo anosayizi abancane bezimbotshana kanye nokukhubazeka okumbalwa ahlala efiseleka kakhulu.

Okwamanje, ubukhulu pore kanye nesakhiwoamagwebu e-aluminiumkunzima ukuzilawula ngesikhathi senqubo yokuncibilika kwegwebu, futhi kuyinselele ukwenza amagwebu e-aluminium anamasayizi amancane wembotshana, ikakhulukazi ngenxa yokubola ngaphambi kwesikhathi kanye nokuhlakazeka kabi kwe-ejenti ephephethayo (imvamisa i-TiH2). Ngokusekelwe kulokhu, iqembu likaProf. Yanxiang Li eNyuvesi yaseTsinghua lafunda inqubo yokuhlakazwa kwangaphambili kwe-TiH2 ekuncibilikeni kwe-alloy ephakathi kwe-AlMg35 ngemva kokwelashwa kwe-oxidation, engaqedela inqubo yokuhlakazwa ngaphandle kokubola, futhi yakha i-AlMg35-TiH2 entsha. i-ejenti ye-foaming ehlanganisiwe. Imithelela yesikhathi esinyakazayo nesikali se-ejenti ephephethayo kwikhwalithi yegwebu elihambisanayo le-aluminium nakho kwahlaziywa. Imiphumela yocwaningo yanyatheliswa kujenali ethi "Journal of Materials Processing Technology" enesihloko esithi "Ukuthuthukiswa kwe-alMg35-TiH2 ehlanganisa i-ejenti eyenza amagwebu kanye nokwakhiwa kwamagwebu e-aluminium amancane angama-pore". Ijenali ye-Materials Processing Technology.Amagwebu e-aluminiumokulungiselelwe nale ejenti enegwebu eyinhlanganisela ibonakala ngesakhiwo esihle, usayizi omncane wembotshana, ukusatshalaliswa kwama-pore afanayo kanye nokuma kwe-pore eyindilinga. Ukuthuthukiswa kwale nqubo ukuthi izinhlayiya ze-TiH2 zihlakazeka endaweni encibilikayo ye-alloy encibilika isikhathi eside esinyakazayo futhi akulula ukubola.

I-ejenti evuthelayo iphumelele ekulungiseleleni izakhiwo zamaselula ezinhle kakhulu neziphindaphindekayo zezimbotshana ezincane kumagwebu e-aluminium anesilinganiso esincishisiwe sosayizi wembotshana ongu-0.6 mm, okwakubangelwa kakhulu isikhathi sokubola esibambezelekile se-TiH2 ngenxa yokwelashwa kwangaphambili kwe-oxidation kanye ne-AlMg35 eshumekwe kuyo. , okwenza isikhathi sokunyakazisa sibekezeleleke. Izinhlayiya ezifakwe ngaphambili kwe-TiH2 zihlakazwe kungxube ye-AlMg35 ewuketshezi, okwenza kube lula ukuhlakaza izinhlayiya ze-TiH2 ekuncibilikeni kwe-aluminium ngokuhlanganisa okuncane kwezinhlayiyana. Ngaphezu kwalokho, le ndlela inciphisa inani le-TiH2 elengezwe esigabeni sokukhihliza amagwebu, elingabizi kakhulu futhi elilungeleukukhiqizwa kwezimboni.
