I-Metal Foam ayisiyiyo eyona ntsimbi inzima kwaye ineempawu ezininzi ezintle

Metal Foams Overview
Metal Foamszizinto eziqulathe iileya zekhekheba lobusi lwezakhiwo zetsimbi ezinomlinganiselo othile we-porosity ezikhaphukhaphu, zifunxa kakhulu amandla, ezisebenza ngobushushu nangombane. I-Metal Foams inokulungelelaniswa kwintsimbi esetyenzisiweyo, ukucutshungulwa, kunye nesakhiwo se-pore, okukhokelela kwiipropati ezahlukeneyo kunye nezicelo ezahlukeneyo ezineemfuno ezahlukeneyo.

Ubunzima beMetal Foam
Amagwebu esinyithi ayizizo zezona zinzima; ubulukhuni babo bunokwahluka ngokuxhomekeke ekubunjweni kwesinyithi kunye nesakhiwo se-pore. Umzekelo, i-tungsten foam inokufikelela kubulukhuni be-Vickers obungama-600, ngelixa i-aluminiyam igwebu iphantsi ngokwentelekiso kwisikali sobulukhuni, ngokuqhelekileyo malunga ne-HV50. Ngokwahlukileyo koko, iidayimani eziqinileyo ezidityaniswe kuxinzelelo oluphezulu kunye namaqondo obushushu zinokufikelela kubulukhuni beVickers obumalunga nama-5,000, obungaphezu kobulukhuni obuphindwe kashumi kunogwebu lwesinyithi.

Iipropati ezigqwesileyo zamagwebu esinyithi
Nangona i-foam yensimbi ayilona nzima kakhulu, isenayo iindidi zeempawu ezigqwesileyo. Umzekelo:
I-1, ilula: ngenxa yesakhiwo sayo se-pore, i-foam yensimbi inoxinano oluphantsi kakhulu, ngokuqhelekileyo lungaphantsi kwe-0.5 g / cm3, ngoko lunokusetyenziswa njengeizinto zokwakha ezinobunzimakwi-aerospace kunye nezicelo zeemoto.
I-2, ifunxa amandla aphezulu: Ubume bepore be-foam yesinyithi ivumela ukuba ikhubaze kwaye ifunxe amandla xa iphantsi koxinzelelo, ngoko inamandla okuchasa ukungcangcazela kunye nokuchasana nokungqubana.
I-3, i-thermal kunye ne-electric properties: i-foam yensimbi ingasetyenziswa njengento efanelekileyo yokufakela i-thermal kunye ne-thermal conductivity material, kodwa inokusebenza kakuhle kombane.

Ngenxa yezi propati zibalaseleyo,igwebu lesinyithiinoluhlu olubanzi lwethemba lokufaka isicelo, elifana nezixhobo zokufunxa ukothuka kweemoto, iinxalenye zesakhiwo se-aerospace, imathiriyeli engangenwa bulletproof, ii-reactors zekhemikhali, kunye nezinye iinkalo.
