Isingeniso Sezinto

I-high-silicon aluminium alloy ingxubevange kanambambili eyakhiwe nge-silicon ne-aluminium, futhi iyinsimbi yokuphatha ezishisayo esekwe ngensimbi. I-high-silicon aluminium alloy material ingagcina izakhiwo ezinhle kakhulu ze-silicon ne-aluminium, ayingcolisi imvelo, futhi ayinabungozi emzimbeni womuntu. Ubuningi be-high-silicon aluminium alloy buphakathi kuka-2.4 ~ 2.7 g / cm³, kanti i-coefficient yokwanda okushisayo (CTE) iphakathi kuka-7-20ppm / ℃. Ukwandisa okuqukethwe kwe-silicon kunganciphisa kakhulu ukuminyana nokuqina kokushisa kokushisa kwe-alloy material. Ngasikhathi sinye, i-high-silicon aluminium alloy nayo ine-conductivity enhle yokushisa, ukuqina okuphezulu nokuqina, ukusebenza kahle kwe-plating ngegolide, isiliva, ithusi, ne-nickel, okushayelwa nge-substrate, kanye nemishini elula yokunemba. Kuyinto ephathekayo ye-elekthronikhi enamathemba abanzi wokufaka isicelo.

Izindlela zokukhiqiza ze-high-silicon aluminium alloy composite materials ikakhulu zifaka okulandelayo: 1) ukuncibilikisa nokuphonsa; 2) indlela yokungena; 3) i-powder metallurgy; 4) cleaner hot ngokucindezela indlela; 5) indlela yokupholisa / yokufafaza esheshayo.

Inqubo Yokukhiqiza

1) Indlela yokuncibilika nokusakaza

Okokusebenza kwendlela yokuncibilikisa nokuphonsa kulula, kubiza kancane, futhi kungabona ukukhiqizwa okukhulu kwezimboni, futhi kuyindlela ebanzi kakhulu yokulungiselela izinto zokwenziwa kwe-alloy.

2) Indlela yokukhulelwa

Indlela yokumithisa iqukethe izindlela ezimbili: indlela yokungena kwengcindezi nendlela yokungena engacindezeli. Indlela yokungena kwengcindezi isebenzisa ingcindezi yemishini noma ingcindezi yegesi ecindezelwe ukwenza ukuncibilika kwensimbi yensimbi kungene esikhaleni sokuqinisa.

3) Insimbi yensimbi

I-powder metallurgy ukuhlakaza ingxenye ethile ye-aluminium powder, i-silicon powder ne-binder ngokufanayo, uhlanganise futhi ulolonge izimpushana ngokucindezela okomile, umjovo nezinye izindlela, futhi ekugcineni usinter endaweni evikelayo ukwakha okokuqina okujiyile.

4) Umshini indlela esishisayo ngokucindezela

Indlela yokucindezela eshisayo eshisayo ibhekisa kunqubo yokuqhafaza lapho kwenziwa khona ingcindezi nokucindezela ngesikhathi esisodwa. Izinzuzo zayo yilezi: ①Umpuphu kulula ukugeleza kuplastikhi futhi uqine; Isikhathi sokushisa sintering nesikhathi sintering kufushane; Ubuningi buphezulu. Inqubo ejwayelekile ithi: ngaphansi kwezimo zokuhlanza, i-powder ibekwa emgodini wesikhunta, i-powder iyashiswa ngenkathi icindezelwa, futhi kwakhiwa into ehlangene neyunifomu ngemuva kwesikhathi esifushane sokucindezela.

5) Rapid Ukupholisa / fafaza sebethule

Ubuchwepheshe bokupholisa / ukufafaza obusheshayo ubuchwepheshe bokuqina obusheshayo. Inezinzuzo ezilandelayo: 1) akukho ukwahlukaniswa okukhulu; 2) i-crystal microstructure enhle nefananayo; 3) isigaba sokuqala semvula esihle; 4) okuqukethwe oksijini okuphansi; I-5) ithuthukise ukusebenza kokucubungula okushisayo.

Ukwahlukanisa

(1) I-Hypoeutectic silicon aluminium alloy iqukethe i-9% -12% silicon.

(2) I-Eutectic silicon aluminium alloy iqukethe i-silicon engu-11% kuye ku-13%.

(3) Okuqukethwe kwe-silicon ye-hypereutectic aluminium alloy kungaphezulu kwe-12%, ikakhulukazi ebangeni le-15% kuya ku-20%.

(4) Labo abanokuqukethwe kwe-silicon okungama-22% noma ngaphezulu babizwa ngokuthi ama-alloys e-high-silicon aluminium, okuyi-25% -70% yawo okuyiyona eyinhloko, futhi okuqukethwe kwe-silicon okuphezulu kakhulu emhlabeni kungafinyelela kuma-80%.

Isicelo

1) Ukupakisha okuhlanganisiwe kwamandla okuphezulu: i-high-silicon aluminium alloy inikeza ukushabalalisa okuphumelelayo kokushisa;

2) Isithwali: Ingasetshenziswa njengendawo yokushisa yasendaweni ukwenza izingxenye zihlelwe ngokuseduze;

3) Uhlaka lwe-Optical: i-silicon ephezulu ye-aluminium alloy inikeza i-coefficient yokwanda okuphansi okushisayo, ukuqina okuphezulu nokusebenza;

I-4) Isinki yokushisa: Isilicon ephezulu ye-aluminium alloy inikeza ukushabalalisa ukushisa okusebenzayo nokusekelwa kwesakhiwo.

I-5) Izingxenye ezizenzakalelayo: I-high-silicon aluminium alloy material (okuqukethwe kwe-silicon 20% -35%) inezakhiwo ezinhle kakhulu, futhi ingasetshenziswa njengempahla esezingeni eliphakeme engasindi yokugqoka yokusetshenziswa kumathuluzi ahlukahlukene ezokuthutha, imishini yamandla ehlukahlukene, nomshini amathuluzi. Kusetshenziswe kabanzi izinto zokubopha ezikhethekile namathuluzi.

I-high-silicon aluminium alloy inezinhlobonhlobo zezinzuzo ezifana namandla amancane adonsela phansi, isisindo esincane, ukuqhutshwa okuhle kokushisa, ukushisa okuphansi kokushisa okushisayo, ukuzinza kwevolumu, ukumelana okuhle kokugqoka, nokumelana nokugqwala okuhle, futhi kusetshenziswa kabanzi njenge-cylinder liners, ama-piston, nama-rotors ezinjini zezimoto. , Ama-disc Brake nezinye izinto.
