High-silicon aluminium alloy ke motsoako oa binary o entsoeng ka silicon le aluminium, 'me ke thepa ea tsamaiso ea mocheso e thehiloeng ka tšepe.Thepa e phahameng ea silicon alloy alloy e ka boloka thepa e babatsehang ea silicon le aluminium, ha e silafatse tikoloho, ebile ha e kotsi 'meleng oa motho.Boima ba alloy ea aluminium e phahameng ea silicon e pakeng tsa 2.4 ~ 2.7 g/cm³, 'me coefficient ea katoloso ea mocheso (CTE) e pakeng tsa 7-20ppm/℃.Ho eketsa dikahare tsa silicon ho ka fokotsa haholo boima ba 'mele le katoloso ea mocheso oa thepa ea alloy.Ka nako e ts'oanang, alloy ea aluminium e phahameng ea silicon e boetse e na le conductivity e ntle ea mocheso, ho satalla ho khethehileng le ho tiea, ts'ebetso e ntle ea ho roala ka khauta, silevera, koporo le nickel, e chesehang ka substrate, le machining a bonolo.Ke thepa ea ho paka ea elektroniki e nang le menyetla e pharaletseng ea ts'ebeliso.
Mekhoa ea ho etsa lihlahisoa tse entsoeng ka silicon e phahameng ea aluminium alloy composite haholo-holo e kenyelletsa tse latelang: 1) ho qhibiliha le ho lahla;2) mokhoa oa ho kenella;3) phofo ea metallurgy;4) vacuum chesang ho tobetsa mokhoa;5) mokhoa oa ho pholile ka potlako / ho fafatsa mokhoa oa ho beha.
Mokhoa oa Tlhahiso
1) Mokhoa oa ho qhibiliha le oa ho lahla
Thepa ea ho qhibiliha le mokhoa oa ho lahla o bonolo, o theko e tlase, 'me o khona ho hlokomela tlhahiso e kholo ea indasteri,' me ke mokhoa o pharalletseng oa ho lokisa lisebelisoa tsa alloy.
2) Mokhoa oa ho ima
Mokhoa oa ho kenya letsoho o na le mekhoa e 'meli: mokhoa oa ho kenella ka khatello le mokhoa oa ho kena ka ntle ho khatello.Mokhoa oa ho kenella ka khatello o sebelisa khatello ea mochine kapa khatello ea khase e hatelitsoeng ho etsa hore tšepe e qhibilihe e qoelisoe ka har'a lekhalo la ho matlafatsa.
3) Metallurgy ea phofo
Metallurgy ea phofo ke ho hasanya karolo e itseng ea phofo ea aluminium, phofo ea silicon le binder ka mokhoa o ts'oanang, ho kopanya le ho bopa li-powders ka ho hatella ka ho omella, ente le mekhoa e meng, 'me qetellong sinter sepakapaka se sireletsang ho etsa thepa e teteaneng.
4) Vacuum e chesang e hatellang mokhoa
Mokhoa oa ho hatella o chesang oa vacuum o bolela mokhoa oa sintering oo ho oona ho thehoang khatello le khatello ea khatello e etsoang ka nako e le 'ngoe.Melemo ea eona ke: ① phofo e bonolo ho phalla ka polasetiki le ho teteana;②Thempereichara ea sintering le nako ea sintering e khuts'oane;③Tekano e holimo.Ts'ebetso e akaretsang ke: tlas'a maemo a vacuum, phofo e kenngoa ka sekoting sa hlobo, phofo e futhumetse ha e ntse e hatelloa, 'me thepa e kopanetsoeng le e ts'oanang e thehoa ka mor'a nako e khutšoanyane ea khatello.
5) Pholiso e potlakileng / ho fafatsa ho beha
Theknoloji ea ho futhumatsa ka potlako / spray deposition ke theknoloji e potlakileng ea ho tiisa.E na le melemo e latelang: 1) ha ho na karohano e kholo;2) e ntle le e junifomo equiaxed kristale microstructure;3) mohato o motle oa pula ea pele;4) oksijene e fokolang;5) ntlafatso ea ts'ebetso ea mocheso oa mocheso.
Karolelano
(1) Hypoeutectic silicon aluminium alloy e na le 9% -12% silicon.
(2) Eutectic silicon aluminium alloy e na le silicon ea 11% ho isa ho 13%.
(3) Likahare tsa silicon tsa hypereutectic aluminium alloy li ka holimo ho 12%, haholo-holo ho tloha ho 15% ho ea ho 20%.
(4) Ba nang le silicon content ea 22% kapa ho feta ba bitsoa high-silicon aluminium alloys, eo 25% -70% e leng eona e ka sehloohong, 'me lihlahisoa tse phahameng ka ho fetisisa tsa silicon lefatšeng li ka fihla ho 80%.
Kopo
1) Sephutheloana sa potoloho se kopantsoeng ka matla a phahameng: alloy e phahameng ea silicon e fana ka mocheso o sebetsang hantle oa mocheso;
2) Carrier: E ka sebelisoa e le mocheso oa mocheso oa sebakeng seo ho etsa hore likarolo li behoe haufi-ufi;
3) Foreimi ea Optical: alloy e phahameng ea silicon aluminium e fana ka coefficient e tlase ea ho atolosa mocheso, ho tiea ho phahameng le ho sebetsa;
4) Mocheso oa mocheso: Alloy ea silicon e phahameng ea aluminium e fana ka mokhoa o atlehang oa ho senya mocheso le tšehetso ea sebopeho.
5) Likarolo tsa likoloi: Lintho tse entsoeng ka silicon e phahameng ea aluminium (liteng tsa silicon 20% -35%) li na le thepa e ntle ea tribological, 'me li ka sebelisoa e le lisebelisoa tse sa sebetsaneng le lisebelisoa tse fapaneng tsa lipalangoang, metjhini e fapaneng ea matla le mochini. lisebelisoa., Li-fasteners tse khethehileng le lisebelisoa li 'nile tsa sebelisoa haholo.
High-silicon alloy alloy e na le letoto la melemo e kang matla a khoheli a manyane, boima bo bobebe, conductivity e ntle ea mocheso, coefficient e tlase ea katoloso ea mocheso, botsitso ba molumo, khanyetso e ntle ea ho roala le ho hanyetsa kutu, 'me e sebelisoa haholo joalo ka li-cylinder liner, pistons. le li-rotor tsa enjine ea likoloi., Li-disk tsa Brake le lisebelisoa tse ling.
