Inkcazelo emfutshane:

I-foam ye-Copper luhlobo olutsha lwezinto ezisebenzayo kunye nenani elikhulu lee-pores ezidibeneyo okanye ezingaxhunywanga ngokulinganayo zisasazwe kwi-matrix yobhedu. I-foam ye-Copper ine-conductivity enhle kunye ne-ductility. Xa kuthelekiswa ne-nickel foam, inexabiso eliphantsi lokulungiselela kunye ne-conductivity elungileyo, kwaye ingasetyenziselwa ukulungisa i-electrode engalunganga yebhetri (i-carrier), i-catalyst carrier kunye ne-electromagnetic shielding material.
Ngokukodwa, ubhedu olugwetywe amagwebu lunezinto eziluncedo ezicacileyo njenge-substrate yee-electrode zebhetri, kodwa ngenxa yokuba ubhedu aluxhathisi umhlwa njenge-nickel, lukwanciphisa ezinye zezicelo zalo.

Ugwebu lobhedu-01
I-foam ye-Copper luhlobo olutsha lwezinto ezisebenzayo kunye nenani elikhulu lee-pores ezidibeneyo okanye ezingaxhunywanga ngokulinganayo zisasazwe kwi-matrix yobhedu. I-foam ye-Copper ine-conductivity enhle kunye ne-ductility. Xa kuthelekiswa ne-nickel foam, inexabiso eliphantsi lokulungiselela kunye ne-conductivity elungileyo, kwaye ingasetyenziselwa ukulungisa i-electrode engalunganga yebhetri (i-carrier), i-catalyst carrier kunye ne-electromagnetic shielding material.
Ngokukodwa, ubhedu olugwetywe amagwebu lunezinto eziluncedo ezicacileyo njenge-substrate yee-electrode zebhetri, kodwa ngenxa yokuba ubhedu aluxhathisi umhlwa njenge-nickel, lukwanciphisa ezinye zezicelo zalo.
Ubhedu olunamagwebu lulungiswa ngumgubo wesinyithi kunye ne-electroplating, kwaye isinyithi esinegwebu silungiswa ngokudibanisa i-agent ekhupha ugwebu kwisinyithi esityhidiweyo;
I-1.I-powder metallurgy metal foams ezenziwe ngokongeza i-agent evuthelayo (efana ne-NH4Cl) kwi-powder, i-agent evuthelayo i-volatilizes ngexesha lokucoca, ishiya i-voids.
2. Indlela yokubeka i-Electrochemical deposition ingasetyenziselwa ukulungisa isinyithi esinegwebu kunye nokumila rhoqo kunye ne-porosity ukuya kwi-95%, kubandakanywa i-foams yensimbi kunye ne-Cu, i-Ni, i-NiCrFe, i-ZnCu, i-NiCu, i-NiCrW, i-NiFe kunye nezinye iintsimbi kunye ne-alloys njengamathambo.

Isinyithi sifakwe kumzimba we-porous nge-electrochemical method, kwaye amacandelo adipozithiwe adibaniswa kunye ne-sintering, kwaye amandla afikelela kwi-foam yensimbi efunekayo ephezulu, ene-porosity ephezulu kwaye inokuzaliswa ngezinto ezininzi, ezifana ne-catalysts. . i-electrolyte, njl.
3. Umngxuma womngxumaugwebu lobheduilungiswe yinkqubo ye-sintering-desolvation, kunye ne-electrolytic powder copper, i-NaCl particles kunye ne-additives zixutywe ngokulinganayo kwaye zicinezelwe kwii-compacts eziluhlaza. Isithando somlilo sifakwe kwi-argon atmosphere for sintering, kwaye imveliso efunyenweyo ifakwe kumanzi ashushu ajikelezayo. Inyibilike kwisixhobo, emva koko ihlanjwe nge-ultrasonic bath yamanzi kunye ne-acetone, kwaye ekugqibeleni yomiswe ukwenza iipores ezivulekileyo, eziqulunqwe nguthungelwano lwesithuba esineendlela ezintathu, kunye ne-porosity ye-50-81%, i-avareji ye-pore ye-0.2- 4 mm, kunye nokuhanjiswa kwepore.

      Inkcazo yeMveliso ye-Copper Foam isetyenziswe ngokubanzi njengokulungiswa kwezinto ezithwala ibhetri, i-electrode substrate ye-lithium ion ibhetri okanye i-fuel, i-cellcatalyst carrier kunye nezixhobo zokukhusela i-electromagnetic. Ngokukodwa i-foam yobhedu yinto esisiseko esetyenziswa njenge-electrode yebhetri, kunye neenzuzo ezithile ezicacileyo. Uphawu lweMveliso 1) ugwebu lobhedu luneempawu ezibalaseleyo zobushushu, lunokusetyenziswa ngokubanzi kwimixholo yemoto/yombane kunye neye-elektroniki yerediyo yokuqhubela ubushushu...
