Aluminium zvikamu
Aluminium alloy ialloy umo aruminiyamu (AL) ndiyo inonyanya simbi.
Izvo zvakajairika alloy zvinhu mhangura, magnesium, manganess, silicon uye chero zinc.
Kune maviri makuru emhando, ayo ekukanda alloys uye akagadzirwa alloys, ese ari maviri akapatsanurwa muzvikamu zvekupisa kunorapika uye kusapisa kunorapika.
Aluminium alloy yakajairika muhupenyu hwedu, magonhi edu nemahwindo, mubhedha, midziyo yekubikira, tableware, mabhasikoro, mota etc. Ine aruminiyamu alloy.
Yakajairika aluminium alloy mukushandiswa kwehupenyu.
Aluminium alloys ane huwandu hwakawanda hwezvivakwa inozivisa huinjiniya mune zvimiro.
Kusarudzwa kweiyo alloy yakakodzera kune yakapihwa application kunosanganisira kufunga kwesimba rayo rekusimba, density, ductility, formability, workability, weldability uye corrosion kubata.
Aluminium alloy inoshandiswa zvakanyanya mundege nekuda kwekusimba kwehuremu hwehuwandu.
Aluminium alloys anowanzo ane elastic modulus inosvika 70GPa, inova chikamu chimwe muzvitatu cheiyo elastic modulus yemhando zhinji dzesimbi nesimbi alloys.
Naizvozvo, pamutoro wakapihwa, chikamu kana yuniti yakagadzirwa nealuminium alloy inodhura yakakura elastic deformation pane chikamu chesimbi chehukuru hwakafanana hwechimiro.
Chiedza chemhando, simba repamusoro, ngura, kuramba, nyore kuumba, welding.
Alloys anoumbwa zvakanyanya nealuminium anga akakosha mukugadzirwa kwemuchadenga kubva pakaunzwa ndege dzakagadzirwa nesimbi.Aluminium magnesium alloys ese ari maviri akareruka kupfuura mamwe aruminiyamu alloys uye isingabatike zvakanyanya kupfuura alloy ine yakakwira chikamu chemagnesium.
Kazhinji, kunzwisiswa kwesimbi pakupisa kunotariswawo, kunyangwe maitirwo emusangano anosanganisira kudziyisa anoomeswa nekuti aruminiyamu, kusiyana nesimbi, inonyungudika isina kutanga kupenya tsvuku.
Aluminium alloy surfaces ichaita kuti zvirambe zvichipenya munzvimbo yakaoma nekuda kwekuumbwa kwechidimbu, chekudzivirira chealuminium oxide.Munzvimbo ine mvura, galvanic corrosion inogona kuitika kana aruminiyamu alloy yakaiswa pamagetsi kusangana nemamwe masimbi ane zvimwe zvakashata zvinokanganisa kupfuura aluminium.
Main alloying zvinhu imhangura, silicon, magnesium, zingi, manganese, yechipiri alloying zvinhu zviri nickle, simbi, titanium, chromium, lithium, nezvimwewo.
Aluminium alloy ndiyo inonyanya kushandiswa muindasitiri yeasina ferrous simbi zvimiro zvemuchadenga, aerospace, mota, kugadzira michina, kutumira uye yakashandiswa zvakanyanya muindasitiri yemakemikari.
Aluminium alloy density yakaderera, asi kusimba kwakakwira.
Iwo alloys anoiswa kufa casting zvino anogadzirwa nealuminium alloy.Iine zvinhu zvemuviri zvechiedza uye yakanaka corrosion resistance uye mechanical properties, uye yakanaka kupisa conduction.Aluminium alloy inogona kupatsanurwa kuita kugadzira uye kukanda zvinhu, uye inogona kuiswa mumhando mbiri: kupisa-yakagadziriswa aruminiyamu alloy uye isina kupisa yakagadziriswa aruminiyamu alloy zvinhu mukugadzirisa zvinhu.Die casting aluminium alloy ndiyo yekukanda zvinhu, uye iyo aluminium alloy iyo inoshandiswa kazhinji haina kukodzera kurapwa kwekupisa nekuti inogadziriswa kuita zvigadzirwa kuburikidza nekufa casting process.
Aluminium silicon series
Iyo general aluminium alloy, yakadai ADC1, inoshanda kumadziro makuru, matete uye maumbirwo akaomarara.Zvirimo zvesilicon zvinhu padhuze ne eutectic point uye kuita iyo yekukanda yakanyungudutswa liquidity yakanaka, ine yakanakisa castability, corrosion resistance, high thermal conductivity, thermal expansion and the part of less 2.65g/cm3, etc.Nekudaro, hazvina kunaka kuve brittle uye brittle, uye iyo anodic oxidation haina kunaka.Kana mamiriro ekukanda asina kukodzera, mvura yakanyungudutswa inononoka.
Aluminium silicon mhangura
ADC12 alloy iri muAl-Si alloy wedzera copper alloy element, ndiyo inonyanya kushandiswa inomiririra yekufa kukandira aruminiyamu alloy, kunaka kwayo kukanda uye michina zvimiro, asi kushomeka kwekuora.
Aluminium-Silicon-Magnesium akatevedzana
ADC3 aruminiyamu alloy iri muAl-Si alloy inowedzera alloy element yakadai Mg, Fe, ine yakanakisa mechaniki zvivakwa, corrosion resistance inokandwa zvakanaka, asi kana zviri mukati mesimbi isingasviki 1% kunamatira nyore nesimbi mold, alloy inoshandiswa zvakanyanya.Imwe ADC5 uye ADC 6 alloys, inozivikanwawo sealuminium-magnesium alloys, ane simba rakawanda, corrision resistant and machined, uye ndiwo akanakisa mualuminium alloy.Nekudaro, nekuda kwehuwandu hukuru hwekusimba uye kupisa kwekuwedzera coefficient, iyo alloy casting haina kunaka.A liquidity zvakare yakashata, inonamira chiitiko chekunamira uye kurasikirwa kwesimbi inopenya mushure mekugaya, saka yakakodzera kune anodic oxidation kurapwa, uye kumwe kusachena kwakadai sesimbi, silicon uye zvichingodaro zvese zvinokanganisa chitarisiko chepamusoro.
Nyika dzakasiyana dzine mazita akasiyana eiyo die-cast aluminium alloy, senge Axxx iAmerican modhi, ADCxx iJapan modhi, LMxx iBritish modhi, YLxxx ndiyo yekuChina modhi.
Kurapa kwepamusoro kwekufa kukandira aluminium alloy zvikamu
Iyo anodic oxidation.
Panguva imwecheteyo, ine inoshanda uye yekushongedza pamusoro, uye yakawanda anodized aruminiyamu alloy inenge 2-25um.
Yakakwirira kusimba uye anti-kupfeka aruminiyamu alloy castings ine 25-75um pamusoro pehupamhi.Aluminium alloy oxide layer inogona kugadziriswa uye kugadzirwa.
Ese marudzi emavara haafambise kana akaiswa oxidized, saka anogona kushandiswa zvakachengeteka munzvimbo dzakasiyana dzemidziyo yemagetsi.
Phosphide/chromium.
Phosphatification inobatsira isiri simbi uye yakatetepa coating iyo inoumba yekutsiva layer pane simbi pamusoro kuburikidza nephosphorus compounds.
Inoshanda kune simbi, zinc alloy, aruminiyamu alloy uye zvimwe zvigadzirwa, izvo zvinogona kuvandudza kushora kuramba uye kupfeka kuramba.
Iyo membrane parizvino ndiyo inonyanya kurwisa aluminium inoshandura firimu, saka inogona kubatwa seyakapetwa kamwechete pamusoro peiyo aruminiyamu alloy.
Iyo micro-arc oxidation.
Kushandisa yakakwira voltage pane zvikamu zvealuminium kugadzira ceramic pamusoro pefirimu, kuomarara kwekuputira uye abrasion kuramba kwakakwira zvakanyanya, uye kusagadzikana kwekuora uye kwakasiyana.
Muganho uri nani pane anode.
Iyo microarc membrane inoumbwa nemapoka matatu:
Iyo yekutanga firimu yakaonda yakasungirirwa pamusoro pealuminium, iyo inenge 3 kusvika 5um.
Chikamu chechipiri ndicho chikamu chikuru che membrane, iyo inenge 150 kusvika 250um.Iyo huru layer yakakwira mukuoma uye porosity idiki uye denser yakakwira zvakanyanya.
Chikamu chechitatu ndicho chekupedzisira chepamusoro.Iyi denderedzwa yakasununguka uye yakashata, saka inowanzogadziriswa uye kubviswa kushandiswa pachikamu chikuru.
Iyo alunina microarc oxidation inofananidzwa neanodic oxidation.
Kushandiswa kweiyo microarc oxidation tekinoroji:
Aviation accessories: pneumatic zvikamu uye zvikamu zvekuisa chisimbiso.
Auto zvikamu: piston nozzle
Zvekushandisa pamba: pombi, simbi yemagetsi.
Zvishandiso zvemagetsi:mamita uye magetsi ekudzivirira zvinhu.
