I-aluminiyam i-foam ifunyenwe ngokuxuba i-aluminium alloy powder kunye nento eyahlulayo ngexesha lokufudumala kunye ne-gasification. Ineempawu zobunzima bokukhanya, i-porosity ephezulu kunye nommandla othile ophezulu. Inazo zombini iimpawu zemathiriyeli yentsimbi kunye negwebu, kwaye inokumelana nempembelelo eyomeleleyo, amandla athile aphezulu, ukumelana nobushushu obuphezulu, ukuxhathisa okuqinileyo komlilo, kwaye inokhuseleko oluluqilima lwe-electromagnetic kunye neempawu zokucoca. Namhlanje, siza kwazisa iingenelo ezisixhenxe zokusebenza zovavanyo lwe-aluminium amagwebu ngokweenkcukacha.

1. Ukuhlolwa kwe-foam ye-aluminium - uhlalutyo lwentsebenzo yesakhiwo
Eyona nto inkulu yesakhiwo se-aluminium foam kukuba inenani elikhulu leepores ngaphakathi, okwenza kube lula ubunzima kunye nokuphakama kwamandla athile. Ngenxa yezi mpawu, i-aluminiyam igwebu iba yeyona sandwich ilungileyo yokuzalisa iipaneli zesandwich composite panels, ephucula kakhulu imowudi yokuguqulwa kwezinto ezihlanganisiweyo phantsi komthwalo, ukuze kuphuculwe ukumelana kwayo nokugoba, amandla oxinzelelo, kunye nokukwazi ukufunxa ingxolo. uphuculo olusebenzayo. Xa kuthelekiswa nezinto eziqhelekileyo zesangweji ye-honeycomb, i-aluminiyam ene-foam iyancipha ngokufanelekileyo iindleko kwaye inqobe ukungahambi kakuhle kwe-anisotropy ye-honeycomb sandwich material.

2. Ukufunyanwa kwezinto ze-aluminium foam - uhlalutyo lwentsebenzo yokufunxa amandla
Inkqubo ukusuka kunyanzeliso ukuya ekunyanzelweni kwezinto ze-foam yahlulwe yangamanqanaba amathathu, inqanaba lokuqala linqanaba le-elastic deformation. Emva koxinzelelo, iipores zangaphakathi ze-aluminiyam enogwebu yemathiriyeli ziye zifumaneke kwakhona. Inqanaba lesibini linqanaba leqonga lokubumba. Xa amandla omatshini we-aluminium ene-foam afikelela kwinqanaba elingenakuhlawuleka, lingena kwinqanaba lokubunjwa kwe-deformation. Ngeli xesha, i-pores yangaphakathi ingena kwi-deformation efana nokuvuthwa kunye nokunyuka, kwaye ekugqibeleni idilike ngokupheleleyo. Xa iqondo lokuwa lifikelela kuqhagamshelwano phakathi kweendonga ze-pore ezichaseneyo, lingena kwinqanaba lesithathu: isigaba soxinaniso. Ke ngoko, emva kokuba i-foam ye-aluminiyam iphantsi koxinzelelo, ifumana i-deformation deformation ekhethekileyo. Kwinkqubo, uxinzelelo luguqulwa lube yimpumelelo ye-foam deformation, ethatha ngokufanelekileyo amandla ombane wempembelelo.

3. Ukufunyanwa kwe-foam ye-aluminium - uhlalutyo lwentsebenzo ye-shock absorption
I-aluminiyam enogwebu ineempawu eziphezulu zokudambisa, amaxesha ama-5 ukuya kwali-10 kune-aluminiyam ecocekileyo. Olu phawu lunxulumene ne-porosity, ubukhulu bepore kunye ne-load-strain amplitude ye-foam ye-aluminium ngokwayo. Ukuphakama kwe-porosity, incinci isayizi yepore kwaye inkulu i-amplitude yomthwalo womthwalo, kungcono ukudambisa i-foam ye-aluminium.

Xa izinto ze-aluminium ezinogwebu ziphantsi koxinzelelo lwangaphandle, ngenxa yokungalingani kwee-pores, ukuhanjiswa kwamandla oxinzelelo akulingani, ukuze amandla aqhelekileyo aguqulwe abe nguxinzelelo lwe-shear, oludla uxinzelelo lwangaphandle kwaye luguqulelwe kumandla okushisa ngaphakathi. imathiriyeli yealuminiyam enegwebu. Ngokwalolu phawu lwemathiriyeli ye-aluminium enogwebu, imathiriyeli ye-aluminiyam enogwebu iba yeyona nto ibalaseleyo yokufunxa ukothuka. Ezinje ngee-bumpers zemoto, izixhobo zokumisa iziphekepheke, njl.

4. Uvavanyo lwe-Aluminiyam ye-foam - uhlalutyo lwentsebenzo yokufunxa isandi
Isakhiwo esikhethekileyo se-pore se-aluminium foam sisenza sibe nokusebenza kakuhle kokufunxa isandi. Xa isandi sidlula kwipore, sibangela ukuvakala kwesandi kwipore, kwaye ukungqubana nodonga lwepore kuvelisa amandla obushushu, kwaye amandla obushushu achithwa nge-aluminium, ngoko ke ubume bepore bezinto zealuminium ezinogwebu ngempumelelo. ifunxa ingxolo. Ukusebenza kwesandi sokufunxa kwemathiriyeli ye-aluminium enogwebu iyenyuka ngokunyuka kwe-porosity, ukuncipha kobungakanani bepore kunye nokwanda kobukhulu bezinto. Ngokweempawu zokufunxa isandi se-aluminium foam, isetyenziswa kakhulu kwizitudiyo zokurekhoda zikanomathotholo kunye nezixhobo zeofisi ezizenzekelayo.

5. Ukufunyanwa kwe-foam ye-aluminium - uhlalutyo lwentsebenzo ye-electromagnetic shielding
Uphando kunye novavanyo lubonisa ukuba imathiriyeli ye-aluminium enogwebu inomsebenzi olungileyo wokukhusela i-electromagnetic. Xa i-high-frequency magnetic field idlula kwi-foam, i-eddy yangoku yamagnetic field yenziwa ngaphakathi kwi-foam, ecima indawo yemagnethi yokuqala. Ngokwale ntsebenzo, izinto ze-aluminium ezinogwebu zisetyenziswa kwigumbi lezixhobo zombane kunye nezixhobo zombane,

Kwizixhobo zokukhusela izixhobo zombane.

6. Ukubona izinto ze-aluminium foam - uhlalutyo lokutshintsha kobushushu kunye nokusebenza kwe-thermal insulation
Ngenxa yokuba izinto ze-aluminiyam ze-foam ziqulethe inani elikhulu lamaqamza omoya anamandla amancinci okudlulisa ubushushu, ukuhanjiswa kwayo kwe-thermal ayiphezulu njenge-aluminium, kodwa ingcono kakhulu kuneeplastiki ezinogwebu. I-conductivity yayo ye-thermal ichaphazeleka yi-porosity, kwaye iphezulu i-porosity, i-thermal conductivity imbi kakhulu. Ngaphantsi kweemeko zendalo zokuhambisa, ubushushu buchithwa ngokutshintshiselana kobushushu phakathi kwegesi okanye ulwelo kunye neendonga zepore. Oku kwenza i-aluminiyam igwebu ibe ngutshintshiselwano olulungileyo lobushushu okanye imathiriyeli yokuchitha ubushushu. Ngokomzekelo, i-deicing device ifakwe phambi kwephiko lenqwelo-moya, kwaye igesi eshushu okanye i-antifreeze ikhutshwa kwizinto ezixutywe ne-aluminium ukuze kuphunyezwe injongo ye-deicing.

7. Ukufumanisa i-aluminium foam - uhlalutyo lokusebenza kokucoca
Ngenxa yokungena kwe-foam ye-aluminium, inokusetyenziswa njengento efanelekileyo yokucoca kwiindawo zebhayoloji kunye neekhemikhali. I-pores kwi-foam ye-aluminium inokucoca kakuhle kunye nefuthe lokwahlula kwiigesi okanye ulwelo, kwaye inokucoca umoya oqinileyo.
