Metal Foam inoreva zvinhu zvakakosha zvesimbi zvine furo pores.Kuburikidza nemaitiro ayo akasiyana ezvimiro, furo resimbi rine nhevedzano yezvakanaka zvakanakira, senge yakaderera density, yakanaka kupisa kupisa kuita, kuita kwakanaka kwekuvharisa ruzha uye kugona kubata mafungu emagetsi.

Iine kukwirira kwemhepo, anenge ese ma pores akabatana, iyo BET yemapores yakakura uye diki yakawanda yakawanda.

Metal foam classifications

Metal Foam inonyanya kuita sealuminium furo, furo remhangura, furo renickel uye mamwe alloys foam.

Aluminium foam ine alloys ane huremu huremu uye ane hunhu hwekunyudza ruzha, kupisa kupisa, kudzikisa vibration, kuvhunduka kwesimba kunyura uye electromagnetic wave, nezvimwe. Izvo zvakakodzerwa nemhedzisiro yekudzivirira layer ye missile, ndege uye zvikamu zvayo zvekudzoreredza, buffer yemotokari, electromechanical vibration kuderedza mudziyo, electromagnetic wave shielding chivharo che pulse power supply, nezvimwe.

Nekuda kweiyo yakabatana pore chimiro uye yakakwirira porosity, nickel foam ine yakakwira gasi kuita, yakakwirira chaiyo nzvimbo uye capillary simba. Inonyanya kushandiswa sechinhu chinoshanda kugadzira mafirita mafirita, maatomizer, catalytic converters, bhatiri mahwendefa uye kupisa ex-kuchinja.

Foam yemhangura ine yakanaka conductivity uye ductility, yakaderera mutengo wekugadzirira pane nickel furo, uye nani conductivity, saka inogona kushandiswa mukugadzirira bhatiri anode (mutakuri) zvinhu, catalyst vatakuri uye electromagnetic shielding zvinhu.

Kunyanya, foam yemhangura inoshandiswa sechinhu chekutanga chebhatiri electrode, iyo ine mabhenefiti ari pachena. Zvisinei, mhangura yekudzivirira kusvibiswa haina kunaka se nickel, iyo inoderedza kushandiswa kwayo.

Metal furo kushandiswa

Mafuro esimbi ane rimwe simba, ductility uye addability, uye anogona kushandiswa seakareruka structural materials.Ichi chinhu chakagara chichishandiswa sechinhu chakakosha chezvikamu zvendege.Munzvimbo yeaerospace uye yezvombo zvemabhomba, furo dzesimbi dzinoshandiswa sehuremu, kupisa-kutamisa. kutsigira zvimiro.Nekuti inogona kuve yakakwenenzverwa, kunama kana kunamirwa pamagetsi, inogona kugadzirwa kuita sangweji inotakura nhengo.Sekutsigirwa kwe simbi ganda rebapiro, iyo yekudzivirira-kudonha tsigiro yemhino koni yemusungo (nekuda kweiyo yakanaka yekupisa conductivity) uye giya rekumhara re spacecraft, nezvimwe.

Pakuvaka, furo resimbi rinodiwa kugadzira zvinhu zvakareruka, zvakaoma, uye zvinodzivirira moto, simbi, kana zvitsigiso zvezvinhu izvi. zvese kunyura kwesimba uye kutakura maitiro ekuderedza kushandiswa kwesimba.Makungu ecylindrical anoshandiswa zvakanyanya muzvivakwa zveinjiniya, zvakaita semafuselage endege nemafuta ekumahombekombe. RIGS.Thin-walled cylindrical shells inowanzokuvadza kana ichiiswa pasi pemitoro, asi kana ganda rinotsigirwa nefuro rinoramba riripo: makoiri, chimiro chine simba guru kudarika ganda repakati risina kusimbiswa rehupamhi hwakafanana nehukuru.

Foam yemhangura iri nyore kugadzira uye iri nyore kukanganisa, saka yakakodzera kune fasteners.

Mafuro esimbi anogonawo kushandiswa sekusimbisa kune akawanda organic, inorganic uye esimbi zvinhu.Semuyenzaniso, nickel foam reinforced aluminium alloy (NFRA) zvinhu zvinogadzirwa mushure mekusimba nekuzadza yakanyungudutswa aluminium munickel foam.

Foam metal yakanyatsokodzera kushandiswa sechinhu chakareruka mupumburu wekutakura zvakasiyana-siyana mapaneru, mabhomba uye machubhu kuita zvakasiyana-siyana laminated composite.Muenzaniso wakajairika wekushandiswa kweporous zvinhu muzvikamu zvekuumbwa is sandwich panels.Sandwich panels inoshandiswa. mundege dzemazuvano shandisa girazi kana kabhoni fiber composite ganda. Iri ganda reganda rinopatsanurwa kubva kune resin muzinga weuchi nesimbi aruminiyamu kana bepa, kana neyakaomarara foam yekupa. iyo sandwich panel yakakura chaiyo yekukotama kuomarara uye chaiyo kukotama simba.Iyo tekinoroji yakatambanudzirwa kune mamwe maapplication apo uremu chiratidzo chakakosha: zvikepe, zvireyi, zvikepe zvekumhanya uye zvivakwa zvinofamba.

Kudzivirirwa kweBuffer zvakare ndeimwe yeakanyanya kushandiswa kwesimbi furo, iyo inofanirwa kuve nekugona kutora simba uchidzora iyo yakanyanya simba inobata pachinhu chinofanira kuchengetedzwa pasi pemuganho wekukuvadza.

Porous foams inonyatsokodzera maapplication akadaro.Nekudzora hukama hwayo, simba remafuro esimbi rinogona kugadziridzwa pamusoro pehupamhi.
