Metal Foam - simbi inofema

Nekuda kwechimiro chayo chakakosha, ine yakakosha zvivakwa muzvinhu zvakawanda. Sechinhu chekugadzirisa, chinoratidzwa nehuremu huremu uye yakakwirira chaiyo simba; sechinhu chinoshanda, ine zvinhu zvakasiyana-siyana zvemuviri senge porous, vibration damping, damping, sound-absorbing, sound insulation, heat dissipation, impact absorption, electromagnetic shielding and so.
Foam metalinogadzirwa neupfu metallurgy nzira uye electroplating nzira, yekutanga nekuwedzera foam agent kune yakanyungudutswa simbi kuti ibudise furo simbi; iyo yekupedzisira ne electrodeposition process pane polyurethane foam skeleton yakadzokororwa kuita furo simbi.
Powder metallurgy nzira yekugadzira furo simbi, inowedzerwa kune hupfu inofuridza ajenti (yakadai seNH4Cl), sintering inofuridza agent volatilization, ichisiya pores. Masimbi efuro ane mapores akajairika uye porosity akakwira kusvika 95% anogona kugadzirwa neelectrochemical deposition, zvinosanganisira furo zvinhu zvine simbi uye alloys zvakaita seCu, Ni, NiCrFe, ZnCu, NiCu, NiCrW, NiFe, uye dzimwe simbi uye alloys se skeleton. Simbi ye electrochemically yakaiswa pa porous body is sintered kuitira kuti zvinhu zvakaiswa zvibatanidzwe zvakazara, uye simba riri kusvika kune inodiwa yakanyanya porous foam metal ine high porosity, iyo inogona kuzadzwa nezvimwe zvinhu zvakadai se catalysts uye electrolytes mu. use.
Aluminium, nickel uye alloys avo anga ari simbi yefuro, uyezve, iyo foam mhangura inewo imwe nzvimbo yekusimudzira.
Foam aluminiumuye ma alloys ayo akareruka, ane ruzha kunyura, kupisa kupisa, vibration damping, kunyura kwesimba rinokanganisa uye mafungu emagetsi uye humwe hunhu, hwakakodzera kupotsera, ndege uye zvikamu zvayo zvekudzoreredza zvekukanganisa kweiyo inodzivirira layer, mota buffers, zvemagetsi muchina vibration. daping zvishandiso, pulse power electromagnetic wave shielding cover.
Nickel foamine yakakwira gasi permeability, yakakwirira chaiyo nzvimbo uye capillary simba nekuda kweiyo yakabatana pore chimiro uye yakakwirira porosity, uye inonyanya kushandiswa sechinhu chinoshanda chekugadzira mafirita mafirita, maatomizer, catalytic converters, bhatiri electrode mahwendefa uye kupisa exchangers.
Foam yemhanguraconductivity uye ductility yakanaka, uye mutengo wekugadzirira wakaderera pane nickel furo, zviri nani conductivity, inogona kushandiswa kugadzirira bhatiri negative electrode (mutakuri) zvinhu, catalyst vatakuri uye electromagnetic shielding zvinhu. Kunyanya, foam yemhangura yemabhatiri se electrode substrate zvinhu, ine zvimwe zviri pachena zvakanakira, asi nekuda kwekushomeka kwemhangura haina kunaka senickel, nokudaro zvakare inoganhura zvimwe zvekushandisa kwayo.
Ichi chinyorwa chakagara chichishandiswa sechinhu chakakosha chezvikamu zvekusungirira ndege. Muindasitiri yemuchadenga uye yekupotsera, inogona kugadzirwa kuita sangweji inotakura zvinhu, senge yebapiro resimbi goko remuviri wekutsigira, missile mhino yekoni yegomba rekupisa kwepamusoro kudonha kwemuviri wekutsigira (nekuda kwekunaka kwayo kupisa. conductivity) uye giya rekumhara re spacecraft. Mukuvaka, simbi yefuro inodiwa kugadzira zvinhu zvakareruka, zvakaoma, zvisingadziviri moto, njanji kana mitumbi inotsigira zvinhu izvi. Iyo yakakwirira-frequency, kukurumidza-kumhanya uye kuderera kwezvikwiriso zvemazuva ano zvinodawo zvimiro zvakareruka zvine zvese zvinotora simba uye zvinotakura zvinhu kuti zvideredze mashandisiro emagetsi. Cushioning zvakare imwe yeakanyanya kushandiswa kwefoam metal, iyo inofanirwa kuve nekugona kutora simba uchichengeta iyo yakanyanya simba ichiita pane chinhu chakadzivirirwa pazasi pemuganho wekukonzera kukanganisa.
