Lihlahisoa tsa alloy tsa aluminium li sebelisoa haholo libakeng tse ngata ka lebaka la ts'ebetso ea tsona e babatsehang.Leha ho le joalo, ts'ebetso ea bona e babatsehang e ke ke ea aroloa ho mefuta e sa tšoaneng ea li-additive alloy aluminium.Lilemong tsa morao tjena, li-additive alloy aluminium li fetohile likarolo tsa bohlokoa bakeng sa ho ntlafatsa ts'ebetso ea lisebelisoa tsa aluminium le ho hloekisa sebopeho sa lijo-thollo.
Aluminium alloy additiveske lik'hemik'hale tse kenngoang tšepe e qhibilihisitsoeng nakong ea ts'ebetso ea tlhahiso.Li-additives tsena li sebeletsa mesebetsi e fapaneng 'me li na le tšusumetso e kholo sehlahisoa sa ho qetela.Karolo ea li-additives tse fapaneng e fapana, mohlala,li-additives tsa chromium, e bapalang karolo ea bohlokoa ho kenyelletsoeng ha chromium ho li-alloys tsa aluminium le ntlafatso ea sebopeho sa lijo-thollo, leli-additives tsa manganese, e ka amang litaba tsa manganese lihlahisoa tsa alloy aluminium.
Ho zhelu, li-additives tsa aluminium alloy li boetse li tsejoa e le 75% aluminium alloy additives, e bolelang hore litaba tsa lik'hemik'hale tse lokelang ho eketsoa ho tlatsetso ke 75% 'me tse ling kaofela ke aluminium, e bapalang karolo ea bohlokoa ho ntlafatsa ts'ebetso le ts'ebetso. boleng ba lihlahisoa tsa alloy aluminium.Ho phaella moo, lisebelisoa tsa aluminium alloy tse hlahisoang ke zhelu li na le lihlahisoa tse fetang 95%.Sena se matlafatsa ts'ebeliso ea thepa e tala, se fokotsa litšila mme se eketsa ts'ebetso e ntle.Sena ha se thuse feela bahlahisi ho fokotsa litšenyehelo, empa hape se khothalletsa tsoelo-pele e tsitsitseng ea indasteri eohle.
Tšireletso ea tikoloho le ho se silafatse li fetohile lintho tse tšoenyang haholo sechabeng.Ho na le tlhokomeliso e ntseng e eketseha ea bohlokoa ba ho sireletsa tikoloho le tlhokahalo ea mehato e baballang tikoloho liindastering tsohle.E 'ngoe ea melemo e ka sehloohong ea ho sebelisa lisebelisoa tsa aluminium alloy ke ts'ireletso ea tikoloho.Lintho tse kotsi li hlahisoa ka mokhoa o ke keng oa qojoa tlhahisong ea lik'hemik'hale.metsoako ea zhelu e shebana le ts'ireletso ea tikoloho le tlhahiso e se nang tšilafalo.Ba latela melao e thata mme ba thusa ho fokotsa tlhahiso ea litšila tse kotsi nakong ea ts'ebetso ea tlhahiso.
Li-additives tse ling tsa aluminium li boetse li na le phello e kholo ea ho hloekisa motsoako.Ka ho hlahisa likarolo tse itseng ka tšepe e qhibilihisitsoeng, li-additives tsena li thusa ho felisa litšila, ho ntlafatsa homogeneity ea alloy le ho ntlafatsa thepa ea eona ea mochine.Ka mohlala,motsoako oa magnesium, eketsa magnesium ingot morero o ka sehloohong ke ho ntlafatsa aluminium alloy die casting performance indicators, haholo-holo ho hanyetsa kutu.Ho ea ka litsebi, aluminium le magnesium alloy die casting e bobebe ebile e thata, ho hanyetsa kutu e ntle, ho bonolo ho cheselletsa le kalafo e meng ea holim'a metsi, ke ho etsoa ha lifofane, lirokete, liketsoana tse lebelo, likoloi le lisebelisoa tse ling tsa bohlokoa.Ho phaella moo, karolo ea aluminium alloy additives hase feela ho ntlafatsa thepa ea mechine, li-additives tsena li boetse li ntlafatsa machinability ea alloy, ho etsa hore ho be bonolo ho sebetsana le ho sebetsana le tsona.Li thusa ho fokotsa bofokoli bo hlahang nakong ea ho lahla le ho bopa, ka hona ho eketsa chai le ho fokotsa likhahla.The machinability e ntlafetseng ea li-additives tsena li thusa ho boloka litšenyehelo le ho netefatsa tlhahiso ea likarolo tsa boleng bo phahameng.
Le hoja li-additives li phetha karolo ea bohlokoa ts'ebetsong ea lihlahisoa tsa aluminium alloy, bahlahisi ba boetse ba hloka ho hlahisa mananeo a fapaneng a thehiloeng ho litšobotsi tsa li-additives tse fapaneng le mocheso oa bona oa ho sebetsa.Ka mohlala, chromium, manganese lekoporo ka li-additives tsa aluminium alloy kaofela li lokela ho eketsoa feela ha mocheso oa tsona o le moholo ho feta 730 ° C, athesiliconletšepee lokela ho sebelisoa tikolohong ea 740°C le 750°C, ka ho latellana.Ho phaella moo, bakeng sa litekanyetso, zhelu hangata e tataisoa ke sete sena sa liforomo:
tšebeliso e nepahetseng ea li-additives ke qeto ea boleng ba ho qetela ba lihlahisoa tsa alloy aluminium.
Qetellong, li-additives tsa aluminium alloy li phetha karolo ea bohlokoa tlhahisong ea li-alloys tse sebetsang hantle tse nang le botsoalle ba tikoloho.Li-additives tsena li kenya letsoho ts'ebetsong ea ts'ebetso ea indasteri ka ho tsepamisa maikutlo lits'ebetsong tse sa silafatsang tikoloho le tse sa silafatsang.Bokhoni ba bona ba ho ntlafatsa sebopeho sa lijo-thollo, ho eketsa litaba tsa ntho ka motsoako oa aluminium le ho ntlafatsa machina a alloy ho etsa hore e be tsa bohlokoa haholo masimong a fapaneng.Ha tlhokahalo ea lisebelisoa tsa tikoloho le tsa boleng bo phahameng e ntse e eketseha, ho tla ba joalo le ka bohlokoa ba li-additive alloy aluminium, ho bula tsela bakeng sa bokamoso bo botala, bo sebetsang haholoanyane.
