2) auala impregnation
O le impregnation auala e aofia ai auala e lua: auala infiltration mamafa ma auala infiltration pressureless. O le auala e fa'aogaina ai le mamafa e fa'aaoga ai le mamafa fa'ainisinia po'o le mamafa o le kasa e fa'afefe ai le u'amea fa'avae e fa'atofu i le va fa'amalosi.
3) Metallurgy pauta
O le pauta metallurgy o le faʻasalalauina lea o se vaega o le paʻu alumini, paʻu silikoni ma faʻapipiʻi tutusa, faʻafefiloi ma faʻapipiʻi le paʻu e ala i le faʻamago oomi, tui ma isi metotia, ma mulimuli ane sinter i totonu o se siosiomaga puipuia e fausia ai se mea denser.
4) Vacuum vevela auala oomi
Ole auala ole fa'amama vevela e fa'atatau ile fa'agasologa ole fa'amama lea o lo'o fa'atinoina ile taimi e tasi. O ona tulaga lelei e: ①O le paʻu e faigofie ona tafe ma densify; ②O le vevela o le sintering ma le taimi o le sintering e puupuu; ③E maualuga le mafiafia. O le faiga lautele o le: i lalo o tulaga gaogao, o le paʻu o loʻo tuʻuina i totonu o le pusa faʻafefe, o le paʻu e vevela aʻo faʻamalosi, ma o se mea faʻapipiʻi ma toniga e faia pe a maeʻa sina taimi puʻupuʻu.
5) Fa'amalo vave/sausau fa'aputu
Fa'amalo vave/sausau tekinolosi teuina o se tekinolosi fa'amalosia vave. E iai fa'amanuiaga nei: 1) leai se fa'amatu'u-malaga; 2) lelei ma toniga equiaxed tioata microstructure; 3) vaega lelei o timuga muamua; 4) maualalo le okesene i totonu; 5) faʻaleleia le faʻaogaina o le gaosiga o le vevela.
Fa'avasegaga
(1) Hypoeutectic silicon alumini alumini e aofia ai le 9% -12% silicon.
(2) Eutectic silicon alumini alumini e aofia ai le 11% i le 13% silicon.
(3) O le silicon anotusi o le alumini alumini hypereutectic e sili atu i le 12%, aemaise i le va o le 15% i le 20%.
(4) O i latou o loʻo i ai le silicon content of 22% poʻo le sili atu e taʻua o le maualuga-silikoni alumini alumini, lea o le 25% -70% o mea autu ia, ma o le silicon content i le lalolagi e mafai ona oʻo atu i le 80%.
Fa'atatauga
1) Faʻapipiʻi faʻapipiʻi faʻapipiʻiina maualuga: maualuga-silikoni alumini alumini e maua ai le faʻafefe lelei o le vevela;
2) Carrier: E mafai ona faʻaaogaina e pei o se vevela i le lotoifale e faʻapipiʻi atili ai vaega;
3) Fa'avaa mata: maualuga alumini alumini alumini e maua ai le maualalo o le fa'alauteleina o le vevela, maualuga maualuga ma le mafai ona galue;
4) Su'ega vevela: Alumini alumini silikoni maualuga e maua ai le faʻamalo lelei o le vevela ma le lagolago faʻavae.
5) Vaega taʻavale: Mea faʻapipiʻi alumini alumini maualuga (silicon content 20% -35%) o loʻo i ai mea sili ona lelei o le tribological, ma e mafai ona faʻaaogaina e avea o se mea faʻafefeteina mama mama mo le faʻaaogaina i meafaigaluega felauaiga eseese, masini eletise eseese, ma masini. meafaigaluega. , Faʻapipiʻi faʻapitoa ma meafaigaluega ua faʻaaogaina lautele.
High-silicon alumini alumini o loʻo i ai se faʻasologa o mea lelei e pei o le laʻititi laʻititi, mamafa mama, lelei le faʻauluina o le vevela, maualalo le faʻalauteleina o le vevela, faʻamautu o le voluma, lelei le ofuina, ma le faʻafefeteina lelei, ma e faʻaaogaina lautele e pei o laina ogalaau, pistons, ma rotors o afi afi. , Tisiki taofi ma isi mea.
