I-Metal Foam - isinyithi esiphefumlayo

Ngenxa yesakhiwo sayo esikhethekileyo, ineepropati ezikhethekileyo kwiinkalo ezininzi. Njengempahla yesakhiwo, ibonakala ngobunzima obulula kunye namandla athile aphezulu; njengento esebenzayo, ineempawu ezahlukeneyo zomzimba ezifana ne-porous, i-vibration damping, i-damping, i-sound-absorbing, i-insulation yesandi, ukutshatyalaliswa kobushushu, ukufunxa amandla, ukukhuselwa kwe-electromagnetic njalo njalo.
Isinyithi sogwebuilungiswa ngomgubo indlela metallurgy kunye electroplating indlela, yangaphambili ngokudibanisa agent agwebu kwintsimbi etyhidiweyo ukuvelisa isinyithi ugwebu; Le yokugqibela ngenkqubo electrodeposition kwi polyurethane amagwebu skeleton iphindaphindwe kwisinyithi ugwebu.
Indlela yesinyithi ye-powder yokwenza i-foam metal, yongezwa kwi-agent evuthela umgubo (efana ne-NH4Cl), i-sintering i-agent evuthela i-volatilization, ishiya i-pores. Isinyithi esinegwebu elinemibhobho emile rhoqo kunye ne-porosity ephezulu ukuya kuma-95% inokwenziwa ngokubekwa kwe-electrochemical, kubandakanywa izinto ezinogwebu ezinesinyithi kunye ne-alloys njengeCu, iNi, iNiCrFe, iZnCu, iNiCu, iNiCrW, iNiFe, kunye nezinye iintsimbi kunye nealloys. amathambo. Intsimbi ye-electrochemically efakwe kumzimba we-porous sintered ukwenzela ukuba amacandelo adipozithiwe adityaniswe ngokupheleleyo, kwaye amandla axhomekeke kwisinyithi esifunekayo esine-porous esine-porosity ephezulu, esinokuzaliswa ngezinto ezininzi ezifana ne-catalysts kunye ne-electrolytes kwi. sebenzisa.
I-aluminium, i-nickel kunye ne-alloys yabo ibe yintsimbi esebenzayo ye-foam, ukongeza, ubhedu lwe-foam lunendawo ethile yophuhliso.
I-aluminiyam yogwebukunye ne-alloys zayo zikhaphukhaphu, kunye nokufunxa isandi, ukugquma ubushushu, ukudambisa ukungcangcazela, ukufunxwa kwamandla empembelelo kunye namaza ombane kunye nezinye iimpawu, ezifanelekileyo kwimijukujelwa, inqwelomoya kunye neendawo zayo zokubuyisela impembelelo yomaleko okhuselayo, izithinteli zeemoto, ukungcangcazela koomatshini be-elektroniki. izixhobo zokudambisa, ipulse amandla e-electromagnetic wave shielding cover.
I-nickel foaminokufikelela kwigesi ephezulu, indawo ephezulu ephezulu kunye ne-capillary force ngenxa yesakhiwo sayo se-pore esidibeneyo kunye ne-porosity ephezulu, kwaye isetyenziswa kakhulu njengento esebenzayo yokwenza izihlungi zamanzi, i-atomizers, i-catalytic converters, iipleyiti ze-electrode zebhetri kunye nokutshintshana kobushushu.
Ugwebu lobheduconductivity kunye ductility ilungile, kunye neendleko ukulungiselela ingaphantsi kunegwebu nickel, conductivity engcono, ingasetyenziselwa ukulungiselela ibhetri negative electrode (carrier) izinto, abathwali catalyst kunye nezixhobo zokukhusela i-electromagnetic. Ngokukodwa, i-foam yobhedu yeebhetri njengezixhobo ze-electrode substrate, ineengenelo ezithile ezicacileyo, kodwa ngenxa yokumelana nokubola kobhedu ayilunganga njengenickel, ngaloo ndlela ikwanciphisa ezinye zezicelo zayo.
Esi sixhobo kudala sisetyenziswa njengesixhobo esiphambili sezixhobo zokubamba inqwelomoya. Kwishishini le-aerospace kunye ne-missile, inokwenziwa ibe yisandwich ethwele amacandelo, njengeqokobhe lentsimbi yephiko lomzimba wenkxaso, iqokobhe lempumlo yempumlo yeqokobhe lokuwa kobushushu obuphezulu bomzimba wenkxaso (ngenxa yobushushu bayo obuhle. conductivity) kunye nesixhobo sokumisa isiphekepheke. Ekwakhiweni, isinyithi esinogwebu siyafuneka ukwenza ukukhanya, ukuqina, izinto ezinokumelana nomlilo, iintsimbi okanye imibutho yokuxhasa ezi zinto. I-high-frequency, i-high-speed speed and deceleration ye-elevators zanamhlanje nazo zifuna izakhiwo ezikhaphukhaphu kunye neempawu zombini zokufunxa amandla kunye nomthwalo wokunciphisa ukusetyenziswa kwamandla. I-Cushioning nayo enye yezona zinto zisetyenziswayo kwintsimbi ye-foam, ekufuneka ibe namandla okufunxa amandla ngelixa igcina amandla aphezulu asebenza kwinto ekhuselweyo engaphantsi komda wokubangela umonakalo.
