Ibiranga Imiterere yibikoresho bya Aluminium

Aluminium ifuro igizwe na anicyuma cya aluminiummatrix materi na pore. Imiterere yimiterere ya aluminiyumu irimo pore diameter, porosity cyangwa ubucucike bugereranije, uburinganire bwa pore, hamwe nubuso bwihariye. Ihuza hagati yimiterere ya pore irashobora gushyirwa mubikorwa nkifungura-selile aluminium ifuro nagufunga-selile aluminium ifuroIkwirakwizwa rya pore ya aluminiyumu isanzwe ntisanzwe, ariko inzira zihariye zirashobora kugera kubikwirakwizwa kuri gahunda. Imiterere ya pore irashobora kuba ifunze-selile yubatswe, imiterere-ifunguye, cyangwa imvange yombi. Imyenge yagufungura-selile aluminiumbirahujwe, mugihe imyenge ya selile ya aluminiyumu ifunze irigenga kandi itandukanijwe hagati yazo kugirango ifuro rya aluminiyumu rishobora gufatwa nkibintu bigize ibice bibiri: materique ya aluminium na pore. Imiterere ya selile ifunze: urukuta rwa pore rufunze rwose, kandi gaze ipfunyitse mu byobo, bigira ingaruka nziza zijwi ry’ubushyuhe kandi bikoreshwa cyane mu kwinjiza ingufu, kurwanya kugongana, n’indi mirima. Imiterere ifunguye-selile: inkuta za pore zirahujwe, hamwe nu mwuka mwiza woguhumeka hamwe nuyoboro wamazi, bikwiranye no kuyungurura, gukwirakwiza ubushyuhe, nibindi bintu. Kubera ko ibipimo byububiko bwa aluminiyumu bigena neza imikorere ya aluminiyumu, mubikorwa bifatika, ibikoresho bya aluminiyumu bifitemo ibipimo bikwiye bigomba guhitamo ukurikije porogaramu zitandukanye. Ugereranije nibikoresho gakondo byibyuma, ifuro ya aluminiyumu irangwa nubunini bunini (ubunini bwa pore D = 0,2 mm kugeza kuri mm 8), ububobere buke (porosity 63% kugeza 90%), nubucucike buke. Imiterere ya skeleton yaaluminiumyerekana ibice bitatu-byo gukwirakwiza, bigizwe nibice bikomeye bya aluminiyumu. Iyi reticulation itanga ibikoresho byiza byubukanishi, nkimbaraga zidasanzwe hamwe no kwinjiza ingufu nziza. Ubuso bwinyuma bwa aluminiyumu isanzwe ikabije hamwe nu byobo bigaragara, ariko ubwiza bwubuso burashobora kunozwa nyuma yubuvuzi (urugero, gutwikira, gutunganya).

Muri byose, imiterere yimiterere ya aluminiyumu ni ububobere bwayo, uburemere n'imbaraga nyinshi, hamwe na skeleton-ya-reticulée. Iyi miterere yimiterere igena imikoreshereze yagutse mubice bya acoustique nubushyuhe bwumuriro, kwinjiza ingufu, kurwanya ingaruka, kuyungurura, no kubaka byoroheje.

Ibiranga imiterere ya aluminiyumu ifuro: (a) aluminiyumu ifunguye ingirabuzimafatizo; (b) aluminiyumu yegeranye cyane
