Mamiriro ezvinhu eAluminium Foam Materials

Aluminium foam inoumbwa nealuminium metalmatrix zvinhu uye pores. Izvo zvimiro zvealuminum foam zvinosanganisira pore dhayamita, porosity kana hama density, pore kutenderera, uye chaiyo nzvimbo. Kubatana pakati pezvimiro zvepore kunogona kuverengerwa seyakavhurika-sero aluminium foam uyeyakavharwa-sero aluminium foam, Kugoverwa kwepore kwealuminium foam kunowanzoita zvisina kujairika, asi maitiro chaiwo anogona kuwana kugoverwa kwakarongeka. Chimiro chepores chinogona kunge chakavharwa-sero chimiro, yakazaruka-sero chimiro, kana musanganiswa wezvose. Mapores eopen-cell aluminium foamakabatana, nepo pores yeakavharwa-sero aluminium foam akazvimirira uye akaparadzaniswa kubva kune mumwe nemumwe kuitira kuti aluminium furo inogona kutorwa sechinhu chinoumbwa chezvikamu zviviri: iyo aluminium matrix uye pores. Yakavharwa-sero chimiro: madziro epore akavharwa zvachose kune mumwe nemumwe, uye gasi rakaputirwa mumapores, iro rine ruzha rwakanaka uye kupisa kwekudzivirira mhedzisiro uye inowanzoshandiswa mukutora simba, kupesana-kudhumhana, uye mamwe minda. Yakavhurika-sero chimiro: madziro epore akabatana, ane mhepo yakanaka yekupinda uye fluid conductivity, yakakodzera kusefa, kupisa kupisa, uye zvimwe zviitiko. Sezvo zvimiro zvealuminium foam zvinotarisisa zvakananga kushanda kwealuminium furo, mukushandisa zvinoshanda, aluminium furo zvinhu zvine ma paramita akakodzera zvinofanirwa kusarudzwa zvinoenderana nekushandisa kwakasiyana. Kana ichienzaniswa nemidziyo yesimbi yechinyakare, furo realuminium rinoratidzwa nehukuru hwepore (pore saizi D = 0.2 mm kusvika 8 mm), high porosity (porosity 63% kusvika 90%), uye yakaderera density. Iyo skeleton chimiro chealuminium foaminoratidza matatu-dimensional reticular kugovera, kunosanganisira yakasimba zvikamu zvealuminium alloy. Iyi reticulation inopa zvinhu zvakanakisa zvemakanika zvivakwa, senge yakakwira chaiyo simba uye yakanaka yekunyudza simba. Kunze kwekunze kwealuminium furo kunowanzo kushata nemapores anooneka, asi mhando yepamusoro inogona kuvandudzwa nekumashure kurapwa (semuenzaniso, kupfekedza, machining).

Zvese mune zvese, zvimiro zvealuminium foam ndeye porosity, huremu uye simba rakakwirira, uye matatu-dimensional reticulated skeleton. Aya maumbirwo ezvivakwa anotaridza kushanda kwayo kwakakura muminda yeacoustic uye kupisa kwemafuta, kunyudzwa kwesimba, kukanganisa kupikisa, kusefa, uye kusimba kwekuvaka.

Zvimiro zvearuminiyamu yakapupuma: (a) iyo yakavhurika-celled foamed aluminium; (b) iyo yepedyo-celled foamed aluminium
